I picked up an old Gehl 2500 a couple of months ago. I bought it knowing it had a engine problems. After playing with the engine that was in it I decided to just replace it. Old motor is a Onan 18 or 20 hp. What I want to put in is a 20 to 25 hp Kubota diesel. Any suggestions with this project would help. Will try to get pictures up in a little while. Tell me what you think about this! This will be my first repower.
