Hi Norm,
I was just thinking about the heavy steering on the ATV ,it may not be only the weight of the slasher making steering
hard as these ATV bikes can be difficult to steer at walking speeds and that's what it's mostly doing when you cut grass .
The one thing I've found with the small Chinese quad bikes is they are easy to steer at walking speed
I guess it's not worth trying to make power steering for the ATV.
Cheers
Max.
