I baled with a JD110 @ 33hp and a JD336 baler for 2 years without any problems. Take your time and slow down when you're in the heavy stuff. I decided to buy a newer baler (1982 model) after several recommendations from TBN members to avoid the older generation of machines because they made extensive use of chains and sprockets versus the later models that used machined gears. Chains stretch and sprockets wear more so than gears. Very difficult to diagnose inconsistent timing problems when you might only be one tooth off if a worn chain jumps.
I also went with a Kuhn DM400 disc mower. During my "formative" years, I had more than enough experience with sickle mowers to know that I didn't care to repeat that level of frustration!
This year will be number 7 for the baler and after using the mower for 3 years, I sold it for what I paid for it.
And that is one lesson that I've learned these past few years - find good equipment, fix what needs to be repaired, maintain it so it keeps working the way it's supposed to; when you want to upgrade, you can look anyone in the eye and tell them it's "field ready" and they'll gladly pay you what you paid for it!
Beyond my yearly operating costs, I have never sold any of my equipment for less than I originally bought it for and I've got folks that now contact me looking for equipment that I might consider selling.
