I love my good-running, maneuverable little tractor with its 6’ belly mower, except it’s like riding a wild bull unless I travel at a snail’s-pace. I’ve tried various pressures with the R-4 industrial tires, but the only relief I’ve found is by hanging a 2,000 lb. concrete ballast off the 3-point arms. Short of this drastic "solution", I’m looking for ideas. Would turf tires be a significant improvement? How about an air-ride seat? I see Northern Tool offers Grammer seats for arounds $1,200, but there are no reviews or any indication they even sell any. I would appreciate hear what you have done to make riding on one of these little tractors more comfortable.
