One of the biggest maintenance items for a gear tractor will be a new clutch. For some folks that will come sooner then later. If you ride the clutch or operate on hills, expect the clutch to wear out quicker then a comparable tractor that does not. On HST, the clutch is used so little, it should never need replacing, that goes for the brakes too. I ride the clutch on my International at times because I'm on hills and mow around sprinklers. It requires alot of extra effort compared to my HST on the Kubota. The clutch on the International is on its last legs. The tractor has 1500 hours on it, the last 200 are from me.
