Ok well if he is only mowing 10 times a year he is asking for trouble - trying to push it through tall grass will wear it out in shorter order
If thats what he is doing, tell him to factor in $36 a cut because it will only last 5 years haha
MF, people don't know how to treat a SP box - most boxes are single speed - if you only pull the lever half way it goes slower but its the same as halfway releasing the clutch on a car.
Pair that with them being sealed units with grease not oil and you have a problem.
