M4900 3 point lift problem

[Texaspsdx]

Will only lift if I pull lever all the way to the top. Then I push lever down and arms start lowering. I have to pull lever back up and try to stop arms at level I want. Tractor is a 2000 model with 454 hours on it.

I don't see how it would affect the lift but does your tractor have a draft control?

I thought I wrote this earlier but it got lost somewhere???

Check the feed back linkage it's located on the top of the three point arms and goes back to the lift and draft valves.
