The old Craftsman DGT6000 lawn tractor shredded another drive belt (it was a year old), the output shaft/rear main seal was leaking like crazy, and it did this thing where if you hit a slight bump while at max mowing speed (not top speed) it would bog way down, blow a bunch of black smoke, and if you weren’t quick on the speed lever it would die out. Oh, the seat cushion separated from the plastic, so it was supremely uncomfortable to use.
