I had a guy build a 6 wheel rough terrain wheelchair 24 volt 4 pole motors. These motors cannot produce enough torque to turn the chair. I have increased torque through the MK6i controller to max to no avail. I feel like I have wasted my money unless I can change to beefier motors. Obviously his idea of rough terrain and mine are different. I want to use it for hunting. I'm open to any and all suggestions.
Hi
As with your post last year, this is probably not the place to ask about electric hardware.
You need a more specific forum or motor supplier to advise you.
Have you measured the voltage and current supplied to the motors to check that they are being driven as hard as possible?
Tom... 
Successful projects along these lines start in the field, where you actually measure the torque required to overcome all important obstacles, then design and build accordingly.
What size batteries are you using.

What motors are these? Part number? Datasheet? What exactly are you wanting to do (ultimately
you'll need to measure/figure out the torque and speed requirements).
Trying to increase the torque beyond the motor's limits just fries the windings, its not the right approach.
Gear-reduction is much more likely to be useful.
Last time the OP posted (first post) he did not respond to questions.
