@chibi2666 The tracks, axles and wheels are all self contained on an assembly that was removed from an old snowblower. A adapter plate made that fit the bolt holes and drive shaft of the wheelchair motors. The adapter plate was welded onto the track assembly. The wheelchair motors i used had a 3/4" keyed drive shaft. The track assembly I used mounted to the snowblower drive axle with a keyed 3/4" shaft. So I put the drive sprocket right on the wheel chair motor drive shaft.
Regarding the sabertooth, it has not over heated and I think the reason is because I'm running at 24 volts, so 3000watts divided by 24volts equals only 12.5 amps. Even if these are 400watt motors that is still only approx 17amps. The sabertooth is not being maxed out or pushed too hard even when there is a reasonable amount of loading on these motors.
The idler is the wheel that doesn't drive the track. Its just a wide smooth wheel so snow that gets between it and the track gets pressed on and builds up like a snowball, that increases the diameter slowly and cracks the track.
These had a tendency to ball up snow around the idler wheel making the diameter larger with packed snow and then cracking the track. So watch for cracked tracks. One of mine has actually got a crack in it and is slightly longer than the other.
@bzeug Where is the idler wheel? I am going to check this more thoroughly when I go to purchase it Monday. $40 for the base, the rubber tracks seemed to be in good condition.
These tracks are manufactured without bearings. This unit was almost completely ceased up. I pressed out the rusty 5/8" axles and replaced the bushings with bearings and new axles. The 3/4" sprocket fit right on the 3/4" wheelchair motor.
The "trac drive" tracks are found on several model of older snowblower. I don't know what brand and model these came from, and it was only a red painted (maybe MTD) base with tracks that I bought. These can still be found on old blowers, I've seen them on Craftsman blowers, 5/24 I think was the model.
The sabbertooth seems to be a good match for these wheelchair motors. I think they are 300 watt motors not the extra large ones that run something like 400 watts.
I've gotten a few inquiries about the construction and performance of my bot. The sabertooth 2x25 has been a solid performer. I don't really pull or haul with the bot though I do push snow and little nephew tried to run it up a tree.
nice work!!!
from where do u buy these tracks?
is there any online store?

HI,
Could you please tell me how you attached the track wheels to the body. What kind of axle configuration did you use.
Thanks

@bzeug What does that convert to in amps? Are you able to pull the full amperage through this driver?
