Question about John Deere 420,1020,2010,2020,2510,2520 Tractor Float
The loader on my 2020 John Deere tractor is slow to raise up and jerks as it raises. Also, at a slow idle, it has rattling sound coming from the hydraulic lines to the front hydraulic pump. When increasing the rpms,
the rattling decreases in volume.
a 6ya Repairman can help you resolve that issue over the phone in a minute or two.

SOURCE: IJohn Deere whinning noise
Is the device that lowers or raises the loader a hydraulic piston type device, or more of a hydrostatic type device? Whining noises are not uncommon with hydrostatic devices...

IF the rest of the hydraulic system has normal pressure, then the control valve for the 3 point may be faulty, or ; the hydraulic cylinder that raises/lowers the 3 point arms has failed (the sealing ring on the internal ring has torn)

Im sorry, I thought you said you changed the oil. My thought was that perhaps the hitch might have bled down during the oil change. That happens occasionally with the tractor I service at work.
I hope you find your trouble. If you could let me know the answer, id appreciate that.

In the worst scenario, the follower, or the piece that senses load on the control shaft , may have broken. Several causes could be the culprit, but happened on my 2520 . Fix requires total disassembly of final drive and differential to remove control arm and repair the follower. Good luck.
