What a tomcat worth
I got mine for 4k but it needed 2k of work. If your looking for one cheap to have fun get one that’s been snowmobile engine swapped. Of course if you want a new 4wd one you gotta shell out 35-50k
All that work and he never tested it to see if it worked. I wanted to see it work.
Too wide and expensive for me. Trails are 65 inch maximum width in my state. That exposed drive belt is a no go! You run over a branch and there goes your belt.
I totally understand about the 65 inch limit. They sell certain models with no cover so that you can change belts literally in seconds during combat, but they also have covers if you’re gonna be in wet places.
cheers from Lebanon, great video
Thanks. Glad it made it all the way to you. If you ever have video ideas send them my way!
Very good! The best, simplest, explanation I've found. Thank you!
Glad it helped!
I would buy one today for an Alaskan sawmill
Grab yourself a three or 5 hp industrial motor and throw a bar on it if you have something to plug into that’s definitely the way to go.

I'm in AZ and this is the most informative video I've seen on TOMCAR. Thanks!
Thank You for the info. How does a bigger tire affect mpg?
By and large, a bigger tire, will give you worse MPG. That being said, it is possible for a larger diameter tire that is much lighter to give you better MPG. It’s all about the tires moment of inertia( resistance to spinning) and obviously about how heavy you are on the pedal. When a figure skater holds their arms out, they’re spinning at a certain speed, but when they pull their arms in, they start spinning faster, even though there was no force supplied to them because they brought their mass closer to the center of rotation. that’s an example of changing a moment of inertia. If you have an extremely large diameter ring of wood(or some relatively light material), it will have the same moment of inertia(resistance to rotating) as a much smaller diameter, solid lead disc. The point being the farther out the masses, the harder it is to spin. When you get into the weeds of rotational dynamics, you actually find out that increasing tire size decreases the inertial mass of your car, although this is typically negated by other stuff. If you’d like a deeper dive into it let me know, and I’ll give you some more detail. Otherwise, I don’t wanna boar you:)
Hey where did you find this??????
Where did I find my Tomcar? Craigslist in Phoenix.
@@redneckphysics I cant believe you got it for 4k. I need to find one.
tucson.craigslist.org/snw/d/amado-2007-tomcar-tm4/7730508933.html
If you’re in Arizona, there’s plenty. Here’s one in Tucson for 5K.
You won’t be able to get the new TX four, but any of the old TM you can find.
I had a TM-4, loved it. Tomcar in Phoenix cares NOTHING about customer service. They want to sell NEW units, not support older units. I took my 4 seater to the factory on a trailer (9 hrs each way) and could not get anyone to even talk with me. I was prepared to spend thousands, just not tens of thousands. They are Israeli, that tells me something.
That's to bad that you had that experience. I personally spent hours on the phone with them while working through a repair troubles, and one of the higher ups even sat down with me and we had a very enjoyable conversation when i went in for a new trany. Maybe you caught them on a bad day...
Did you just randomly show up to the factory? If so, I doubt many manufactures would react any different.
Any design engineer that designs automobiles should have to *_WORK ON THEM for 10 YEARS FIRST!!!_*
Yes it should be required!
Just a little bit of hands on experience goes a long way
If there was ever a waste of effort.....you're watching it now.
Well done guys. And ignore the naysayers hereabouts, the fact that you got this put together in 10 weeks in an attempt to solve a problem bought about by a stupid (though well intentioned) law change is pretty impressive. I think California has many more and much bigger problems they should deal with than small petrol engines. That law is ridiculous!
Everything’s gotta start somewhere.
Cool design! Not enough batteries though
Had me going till you said you can plug it into a standard outlet......12hp 9000w nope
I didn’t mean to insinuate that we were pulling 12hp off a wall plug. More like 2
The sale of gas is banned but what about for government and essential industries??? I’d put my money on they buy out of state and use instate without problem. Also I’ve heard a whisper that if memory serves me correct, EGO or ECHO have a high end forestry saw made but with current battery tech it only runs for about 12 seconds.
Speaking as a climbing arborist, and having 23 years of experience, I have to say that what matters most for the cutter is chain speed and torque. Without enough of either you simply cannot control your cuts, meaning unpredictable behavior from the piece being let go. When operating over houses or in an urban environment in general, uncontrolled cuts are not allowed. The weight of the machine and its center of mass have a major role as well. Internal combustion power saws are a thing of beauty, with many decades of experience and engineering behind the design. This electric fad is interesting, I am enjoying seeing how people are attempting to solve the issues at hand, however it will be a very long time before I trust my life, the lives of my crews, and the property of my clientele to an electric saw.
Well done...
the environmental regulators are out of control. they can't just say good enough. they have to make rules for everything,. in ny state they now regulate parts washers in all businesses .??? the emmissions from those are trivial but no they gotta do it. they have also banned gas appliances as well in new builds.
idiot legislators in california need to make exceptions for people like firefighters. but the law is an ass as they say. so if they can't cut down the trees in a forest fire more of them will burn and more acreage will burn. how is that good for the environment?
I mean great job on the build like I said it's amazing
And I don't believe that there's no way that matches gas powered performance. I'm sorry. I would love you to do a video with. And 066 next to that in the same log
Yeah, there's no way I'm going to that saw from gasoline. Never sorry great build though definitely
So, if I've got this correct, in California if you're fighting a forest fire that's emitting an enormous amount of pollution into the environment each second that it burns you can't use a chainsaw with a small gas motor to help stop the fire because the small engine pollutes the environment? Boy howdy! We're making progress now!
Yep. One BIG YES SIR.
Have they banned using heavy equipment like dozers to push through a fire break, or do they just have to be the latest newest low emissions models? Seems like they are chasing things that don't matter and I am pretty sure no private company would risk expensive brand new heavy equipment on a fire line, old cheap and reliable is the way to go, but hey if it's us forest service it's only taxpayers money right
@@CameronGarben Watch, Western Truck and Tractor Repair. The guy who runs that channel works in northern California and works on a vast array of equipment. He was working on some older dozers a while back and talking about that very thing. A lot of the equipment used to fight the California wildfires are operated by contractors. There are a lot of old dozers equipped to fight the wildfires, but the state of California won't hire them on as contractors because the old dozers don't meet their new emission standards. Meanwhile while the wildfires blaze out of control the older dozers are just sitting there.
@TheLangko this lack of logic and common sense they seem to have makes my brain hurt. They are not smart enough to put in a small amendment to the law that during a ln emergency situation where lives property and people's livelihoods are at stake that their silly CARB laws don't apply
@@CameronGarben If you haven't noticed common sense is in short supply nowadays.
They simply used technology from old Soviet battery watches. The watch is small, light and comfortable. The battery is located on two railway wagons. still, could be worse. What is it that doesn't light up and doesn't fit in your ass? a Soviet device for lighting up the ass.
And to charge those batteries out in the forest, someone on the team will carry a generator. Bingo. Wonderful machine I'm sure it's great, kudos to the team for their effort. But these cutthroat, hack-down policies are the real problem. The politicians have probably never held a power tool in their own hands. They care about the green deals and have no real idea what their decisions do out in the field.
Necessity is the mother of invention, self-imposed scarcity the mother of nonsense. I see you all bundled up, power tool batteries have a hard time in the Florida summer, how much more so a California forest fire.
Well said.
how would it work on MX Fuel or Power Adapt batteries?
It would just be a matter of adjusting the ESC a little bit.
But the next few weeks here I’m gonna start over so I’ll think about going to MX fuel instead of the M18
Maybe get the mx fuel battery off the tool and into the backpack, I belive milwaukee actually just showed the backpack battery extension for mx fuel as an upcoming product at one of the latest trade shows
Great now firefighters have to log equipement around that is double the weight and only lasts half as long, California is clearly digging its own grave with these mandates...
If only actually, it lasted half as long:) mathematically, even with six Milwaukee batteries and the motor running 100% efficiency if you’re actually pulling 7 to 9 kW you’re only gonna get about five minutes full load. It’s kind of comical
@@redneckphysics Now someone has to show me who can take down a BIG tree in 5 minutes, if you even can't take down a single tree with one battery charge, whats the point. I mean the concept is kinda cool and 9kW is ALOT of power for a chainsaw, especially with the torque you are getting out of the electric motors but its the weight man. Even hauling a big gas powered chainsaw around is really tiresome after just a few hundred yards...
That’s a joke California. Surely.
Small engines ban? You could go with baterries... or you could LS swap it. No small engine anymore
Note… they only band spark ignition:) time for the return of the Comet diesel!
Ten weeks of thought is not enough time, go back to the drawing board. I've run power saws for 18 years, many of those years as a professional. I have run the small battery operated Husqvarna saws all the way up to Stihl 880's. I have also run a 20v DeWalt and was thoroughly unimpressed. Battery operated saws have their place in some home owner uses and even in some professional tree service uses, where the cutting is more "occasional." A decent battery (like the Husqvarna) powering a narrow chain on a short bar will last about half a day in this type of usage setting, cutting limbs and even bucking small "logs." Like 1-3 cuts every 15 minutes. A handful of disposable tool batteries running a 3/8 or .404 chain on a 4 foot bar will most likely not last much time at all. That's probably the reason that you failed to demonstrate the saw you created making one single cut with that huge bar and chain setup. It can't do it for any reasonable amount of time, if at all. I didn't even see it spin the chain in the air! Can it even do that? A battery operated saw will always fail miserably trying to keep up with a gas powered saw when it comes to the near constant cutting that occurs in other homeowner use and professional settings. Spending a day in the woods running 8+ tanks of fuel through a power saw will never be outdone by a battery powered saw. Most especially considering that with the recent advent of fuel injected power saws like the Stihl 500i, the mark that battery operated saws have to match or beat has now moved considerably. So this video was basically a demonstration of how someone can make their own crappy disposable battery operated saw just like a DeWalt or Makita and it can use up to 6 batteries to run it. But there's no point in using all 6 batteries, when instead, a person could either use their much better suited gas powered saw, or they could use one of the battery manufacturers' saws and it only uses one battery at a time. The big bar and chain on this battery powered franken-saw is pure click-bait. You are better off marketing this to the type of people that buy "wood sharks" and "wild things." Attempting to market this to firefighters, thinners, and loggers will only continue to get you laughed out of the room. California's only solution to banning gas powered saws will be burning up even more than they already have until there's nothing left to burn.
When school gives you 10 weeks you only have 10 weeks:) in the next few weeks here I’m completely starting over and will be making a ground up chassis instead of retrofitting, a 660. In the video you can see me making a face cut with the large bar. And yes, it also spins in the air:) I agree with pretty much all of your grievances, but it was just a school project.
Mate they're trying to help people, don't whinge about it. I'm sure they're aware of its shortcomings, they deserve a pat on the back for their forward thinking
@@kurts64That's where you are wrong. #1 It's a school project which should indicate that there is an underlying motive to get a good grade. #2 It's a feeble attempt to adapt to an outrageous standard being adopted by lawmakers who only have an agenda to ban gas powered saws and other machines because they feel it is morally correct. They then force their moral standard on the people who DO know better. Just like you, telling me that I don't know better, when my 18+ years of experience should indicate otherwise.
@@Ian-mo1gv I'm wrong in saying they're trying to help people? Or Im wrong in saying they should get a pat on the back? Nowhere in my response did I say that you should know better, or mention your experience. BTW it should go without saying that we all think the law is stupid. It's obviously stupid. But in my opinion these guys are at least thinking about ways to navigate it so guys like us can still get our jobs done.
@@kurts64I will be as clear as I can then. I believe you are wrong in saying that this is forward thinking. Saying that it is, is just as stupid and backwards as banning gas powered saws based on moral superiority. It will not help sawyers to continue to get the job done, as it doesn't prove to be an effective replacement. Trading an 044 for a Milwaukee saw is a joke. I felt as though I made this abundantly clear in my original post, yet you somehow missed all those points and chose to call it "whinging." I agree with you when you say at least they tried. But I think they failed to show us anything new. You seem to think they are making some sort of leap or bound forward and I completely disagree.
It looks like ten weeks of thought went into this…who is going to buy, charge and then carry up to six Milwaukee batteries? What do you do out in the woods when your batteries are dead after 15 short minutes? Someone above suggested a backpack setup for the batteries. It’s a great start to making this somewhat usable. How are you going to charge the batteries away from home in a timely manner? The cost of gas vs just buying the batteries isn’t even a comparison.
I'm all for green tech, but... Small portable tools like chainsaws are going to be real hard to compete with, as a production cutter, you simply can't pack enough batteries to finish the day, when you burn 2-3 galons of fuel in 6 hours, battery tech just isn't ever going to be up to it, but also, small engines are a drop in the pollution bucket, heavy industry by far produces more then a few 1000 chainsaws
I could not agree more... The math is kinda comical when you compare the energy density of lithium with gas. That being said, I gotta try something cause once Cali gets an idea in there head.... :)
@@redneckphysics yeah, they are pushing for it up here too.... and I'm a fan of electric vehicles but come on man
Nah, if I lived in California, no way would I give up the gas power.
I believe the ban is for commercial work. If I was an arborist or landscaper I'd just install a loud speaker on my saws that makes the chainsaw sound lol
I totally agree! There’s nothing like tuning up your saw by ear, and then letting it rip.
love it! Have you considered tethered batteries that you would carry around your waist/backpack? That would remove the weight of the chainsaw entirely from your arms. It would imagine it would have to have a quick disconnect as well (magnetic would be cool). But since you already have a wall-plug option, wouldn't that be a "relatively" quick mod? The scalability of this is fantastic--more batteries, more power. I think this feature has been intentionally left out of electronic devices to force people to pay for entirely new units when they want a bit more power. Anyone who builds chainsaws = permanent man card membership.
We did consider backpack batteries. It’s just that firefighters already have a lot on their back and need to be able to drop the saw and run at any time.
Nice project, good job, but the whole premise is ludicrous. You're putting out a wildfire that's producing way more emissions than any number of chain saws. Oh wait... it's California - doesn't have to make sense.
This is a great idea, im an arborist/ restoration tech and currently the electric saws dont hold up for the amount of time i need to be cutting in a day, and i cant afford to have 8 batteries and constantly charging when in a remote location. Need to consider that a firefighter might be hiking up to over 20 miles or so each day so 30lbs isn't great. If you cant reduce the weight then consider some sort of transport modular carry pack to accommodate all the batteries and the powerhead.
Me and the rest of the team will be starting our design from scratch and should be able to shave. I’d say 3 to 5 pounds of unneeded chassis weight. Even with that you’re 100% correct that a carrying belt is mandatory
cheers brother, you're fighting the good fight@@redneckphysics
as an arborist I commend you but the sooner you figure out that weight problem the better. something that runs just as good as an 880 but weighs 5x-10x as much is not really marketable for people in the industry. Milwaukee's new line of electric chainsaws are impressive but still weigh too much compared to their gas alternative. I'm not trying to be too critical cause what you guys have accomplished is remarkable. I'm just saying if you can figure out how to minimize that weight and maintain that power you have a billion dollar idea.
very true! right now the power head weighs in at around 30 lbs with all 6 batteries installed. So pretty much like an old 090.
@@redneckphysicshow much continuous runtime do you get in the wood? What diameter log?
At this point, I don’t have very many good numbers As far as physical testing goes. Myself and the rest of the people on the team will be completely starting over here in the next few weeks because the current motor set up keeps overheating and I’m not even sure we’re getting the power it’s saying…
Mathematically at 100% efficiency you would only be able to get about five minutes of full load 7 kW 9 hp use.
Batteries are lame:)
Hey RedNeck, I'm curious has TOMCAR reached out to you? Danged if you ain't the best orator going in all things that matter when it comes to this mighty enduro 4 X4... then no one is.
The sun is embarrassed to shine in your world as your brilliance exceeds our star's lumens by, help me here Michael, I'd say a factor of ten.
Is there anything you have yet to get stumped with in calculus?
Yes certainly, I only understand enough calc to use a computer program to do it for me:)
Ohhh, Got It! Nope, no not even close. But I admire that you try to help one that loves anything mechanical without really understanding much about the physics behind the why.
Just fun '411' for this Boomer and whatever you're up to today Mr. ReNeck, be safe and may we see more sometime in the near future.
OMG, You're Dang Right there good buddy! But I Subbed anyways bc of your honesty. I absolutely do not like being asked to do something that I need not be asked to do. I had begun to wonder if for monitization it is obligatory for the ask by Giggle to be inserted.
Well I ain't monetized so I guess I'm not sure if it is required...
I have a 2023 that you are welcome to do a review, let me know location Frisco, Texas
Thanks for the offer! Unfortunately I’m stuck going to school and working in Indiana but if I can ever get over to Texas…
Well explained
My Tomcar TX2 is ancient... but still takes me where I want to go and back. Speedometer doesn't work anymore but they are easy to field repair and are tough as hell. I live in Arizona so think MOAB and the Centipede. I think mine is on the 2nd Kohler engine now with 100K+ miles on it. I was used as a rental in Sedona for 10+ years, 8 hour days 6 days per week with no breaks. Runs like a tank.
100k miles for real?!!! That’s pretty wild.
Did you swap the rear diff out for the OEM one available from CanAm?
I thought about it but no... The turf mode diffs that the OEMs put in have a considerable failure rate. Polaris especially. I wanted to avoid this and also allow for a purely front wheel drive set up.(like a twin stick transfer case) So what I ended up doing is making the half shafts themselves be able to engage or free spool. This gives you complete control if you want just one wheel or neither or both wheels driving. With the addition of cutting brakes this will allow for a pure front dig, with either one or both of the rear wheels locked by the brakes. Or a 3wd dig to either the left or the right. From a "turf mode" standpoint you could drive around on your lawn in one wheel rear drive, or if you disengage both rear axles and then engage 4wd you would have an open diff front wheel drive rig. You can pretty much have any combination you want of various wheels driving! I am hoping to be in some scale production this summer. You will be able to by bolt in replacements for your axles that can do all the stuff talked about above. Is there a particular SxS that you would want it for?
@@redneckphysics It would be for a Commander 1000 XT...I am looking to purchase one by this summer
I just am flabergassed at your replies or is it more that I'm 'Gobsmacked' either way, you sure don't skimp on the answers. Oh and your content and overall production is sublime @@redneckphysics
