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...

SOURCE: John Deere 4410 three point hitch will not raise.

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.

You may need to do a compression test on the engine to confirm whether or not the head-gasket needs to be replaced,that's where i would start if the thermostat is not the problem and the hydraulics are not loading up.Check for oil in the radiator or anti-freeze in the oil as well as for white smoke out of the exhaust,all are indicators of a bad head-gasket.

My thee point hitch quit lifting on my 1979 2840 JD.the last time it happened i added some tractor fluid and it started to work. not this time


There must be a leak for it to need fluid. When so much fluid leaks out there is no hydraulic pressure it means the pump is running dry and is likely to be subject to a high rate of wear.

Whether or not the pump is faulty or the system airlocked or there is a relief valve stuck open is really a task for someone familiar with hydraulics who is on the ground where you are.
The pressures involved can be dangerously high and it is difficult to make a proper diagnosis without measuring those pressures.

Probably the most common cause is low transmission fluid level. Next might be low hydraulic pressure, or loose band adjustment. Let us know if this steers you in the right direction for a solution.

A WING ON THE JD 15' MOWER WILL NOT LOWER. ANY IDEAS?


Just an idea but my guess is that it is in the hydraulic system.
Probably a safety valve that prevents it from falling in case of a hydraulic line break.

Hi, don't know if you have checked this but anyway if you hydraulic oil filter is clean there may be another sintered bronze filter in the sump of the hydraulic tank this could be patially blocked> don't know this particular machine but if it is partially blocked it may be that you will clean that or there is air in the hydraulic system. Hope this is of some help.

Three point hitch on 2020 Jogn Deere Tractor will not raise.


The three point hitch raises with hydraulic pressure. When the hitch will not raise the first thing to check is the hydraulic fluid level. If it is low add hydraulic fluid to the proper level as stated in the owner manual.

John Deere 1020 Weak 3 point hydraulics


I would suggest you find a JD dealer and buy a manual if you want to do the maintenance yourself. You can also do a Google search and find manuals.

I would also suggest you completely drain the old hydraulic fluid and replace it with new fluid and a new filter if it has not been serviced any time in the recent past.

The symptoms you describe can be low fluid and/or a clogged filter. If you or anyone else has run the tractor too long and it has low fluids and/or a clogged filter, you can damage the hydraulic pump and that can get costly.
