JOHN DEERE 1020
New User
Hi guys, I'm new to the forum so bear with me!
I have a later model (1970) john deere 1020. I bought it at an auction so i don't have any maintenance history.
My problem is the 3pth being slow to rise with or without an implement on it. The tractor runs great, drives and shifts very well. The line coming from the front hydraulic pump is vibrating in and out of the pressure control valve, the valve itself sounds like its chattering when the 3pth does lift a bit then the 3pth stops and so does the chatter. I have put new hydraulic oil in, the old oil wasnt milky or full of air bubbles.
My 1020 has manual steering and no hydraulic remotes. Also has a rear and mid mount pto. The brakes both work great. One side note is the previous owner had a mid mount sickle mower on it, it has since been removed. I did notice they plumbed the hydraulic line coming out of the backside of the pressure control valve into the bottom cover of the filter screen.
Hopefully someone has some ideas on whats wrong, I haven't checked pressures yet. I'm thinking maybe the pressure control valve is at fault?
thanks in advance for any advice!!!
