Is there a utility cart like a mule or gator that has a tachometer and a manual transmission and a very low gear? I have a blueberry farm and my tractor won't fit down the rows of mature plants without rubbing and breaking the canes.I have two golf carts one electric,one gas, the electric one heats up and smokes wires after prolonged slow speed use.The gas one has a centrifugal clutch,its to hard to maintian uniform speed.The field has about a 10 deg. pitch to it which makes up hill slower than downhill. So far I only looked at the E-Z go workhorse it has a centifugal clutch. BTW I keep the wires and connections on my electric cart clean.
