differential braking.....

has anyone figured out how to do differential braking on a mower yet? I think it would be sweet to be able to swing the front end around like you can a farm tractor lol I know i could use it in the woods when pullin out trees for firewood

I guess you could. You would need a brake on each axle even though that would basicly make it a zero turn

A brake on each axle would do it just fine. It wouldn't be a zero turn since a ZT reverses one wheel while the other one is going forward. It would give a very small turn radius. Remember that the unbraked wheel will speed up as the braked axle slows down

i have thought about doing this so you could have a unlocked dif and still be able to have it posish kinda like some Toyota trucks have.

Diff brake is far from posi. Its made to lock one axle or the other so the opposite spins.

it works on full size tractors

Full size tractors usually have limited slip or differential locks. If you try a diff brake setup on a straight axle, it wont work.

I messed around on a 4020 with the dual brakes it's ok for tight turns and all but it won't help if your stuck most of the time it will just burn up your brake.
