For no apparent reason, 3 pt hitch arms quit lifting.

Look at the posts related to your hydraulic system - I have the same problem, as well as the loader not lifting, and a hydraulic oil change along w/ screen cleaning & filter replacement should do it.

If hydraulic fluid gets over heated it will fail causing your hydraulic system to fail for sure do like the other post says change filter fluid and check screens for wear of chips from gears or casting build up blocking screen intake!
