I recently acquired a JD 425 in fair condition with 1700 hours although engine rebuilt 100 hours ago. I love the tractor. Big difference from a cub cadet lt1042. I put a tri-cycler mulch kit on the 48" deck and it cuts superbly, although it does not cut long enough for my taste. It is set at max height and still seems short. Tires are correct size so I don't know what else to look for. BTW it is AWS. Occasionally the engine runs rough at start up but infrequently. I am going to rebuild the carb soon as I got a kit a couple days ago. I have a technical service manual on CD but am looking for a OM144042 operators manual and have not had any luck finding one. The steering is "loose" and looks like the front steering pivot has way too much play in it and am looking for advice on how much play it should have and how to fix. It is hard to keep straight when mowing. I plan on going through the Tough-Tork K91 hydro trans this winter and replace seals that are leaking and I am looking for a starting point on doing that. Any advice would be appreciated.
