I worked as a mechanical engineer in tractor design and manufacturing for 42 years. However, those were big tractors. I'm looking to upgrade my lawn tractor to something with a more substantial transmission. My 20 year old Craftsman served me well (with a number of weld repairs to the front axle and frame). The hydro is about shot. So I will be posting some questions on the forum to find something with a k62 or heavier trans. Oh, one thing, I worked for IH and Case IH. Can't buy anything with yellow wheels.
