On my 36" Mini Fastrak I have noticed on some inclines that when I am traveling across the incline the left side pump tends to not hold very well and when I am making a slight turn the mower will veer to the right and continue that direction even though I am putting pressure on to go left. Make sense? Are the EZT pump/motors as strong as the seperate wheel motors and pumps on the commercial mowers? What would be an easy test to see if i have a problem or if the incline is just too steep? I hope that makes sense????
