I want to say hello to everyone. I have been coming to this site about a year now and always seemed to find the info I needed. I have a 3 point lift problem and did not find my answer so I thought I better sign up. I have a L1801 that the lift will creep down from the up postion after it is shut off. Takes about 2 to 3 minutes to get to the full down postion. When running everything works great. The 3-point will not stay in the up position when engine is off. This only started last year but before that it was always rock solid. I do mow with this tractor with a finish mower and I do work the lift up and down alot when turning. Could this be a worn piston and seals or is there something else that could cause this.
