How much torque does your AATV produce?

[Tinodesis]

I'm considering building a hydrostatic 6x6 and want to buy transaxles that are capable of delivering the torque I need. I'm interested in torque at the wheel. The transaxle I'm looking at is rated for 220 ft/lb continuous; 415 ft/lb intermittent.

I know every machine is different, but if you know what yours is rated at please post.

Thanks.

45.7 at the wheel. This was on a chassy dyno. 52hp at 7700 rpm.

Hope this helps. I have a video of it on the Crush thread.

Thanks Lewis. I feel more confident with my math now.

I wish I had run the numbers before buying the hydro transaxles I did. I'll be lucky to get half my money back. I sold a battery charger from my electric buggy to pay for the ones I need.

There are several hydraulic conversion projects on the site, but none of them are posted to completion. Makes me wonder why???

I enjoyed the videos on your Crush thread. You have a great looking machine!

You are looking for actual torque on the wheel which could be several hundred ftlbs. If you think about a 1200lb argo spinning it's wheels, means there is alot of twisting force.
Lewis is talking about engine horsepower and torque that was measured AT the wheel.

Hi Jim,

I think I understand what you're saying. I should have posted my math so others could follow and make corrections. I used the following equations:

Torque = hp x 5252 / Speed (rpm)

HP = Torque (ft/lb) x Speed (rpm) / 5252

Speed = hp x 5252 / Torque
