The wheel motors have given them tons of trouble.
I have several people how have repetitive failures every 500 too 800 hours.
The repair is several grand per side.
The factory dealer here who sells in this area will not replace them under warranty till they completely die.
Normally they give intermittent trouble first of randomly they will stop pulling.
Most have traded out of them when financially possible or when the extended warranty expires.
Bobcat makes a good machine .They say they have the wheel motor problem fixed.
I prefer Pilot controls and do not care for the suspended track machine.
Only one choice out there right now.
