Hello all,

I have this Farmpro 2420 tractor and recently rebuilt the hydraulic lift and replaced the hydraulic filter under the seat, hoping to address a slow drop issue. I still have this very slow drop when an implement is attached. I have the adjustment screw in as far as I can without totally keeping it from dropping, but it is barely above that point. It is workable for now, but I would like to be able to set the height and be able to leave it there when grading the driveway and such. Any ideas of what to check and/or replace? I did notice the rubber o-ring on the piston itself didn't quite seem thick enough to fill the gap between the wiper/scraper rings, but was way tighter with the new rings compared to the old shredded ones. Amazingly, the lift still operated with them before the replacement. I couldn't see any gouges or such on the inner surface of the cylinder and the lift doesn't have any sudden drops or anything during the entire operation up and down. I am at a loss to figure out what to do next.

Thanks for the assist,
Bryan

So you can't position the three point? It's either up or down all the way?

It operates, but when you set it at a whatever height you want, it will very slowly drop. Doesn’t matter how high you set it.

Yep, been through that thread already and did what was suggested by rebuilding the lift cylinder with new o rings and wipers, but didn’t completely resolve the issue.

As I’ve never worked on hydraulic systems before, how would be the best method to do so? I have a sense of what needs to be done, just not how to go about it.
