JD 4100

[TonyBMI]

Hello everyone

Have a problem with a 4100 JD three point lift links

After 3 times to a dealer and talking to 4 others the 3 point still fails to lift.

Have a Land pride 5 ft finish mower 440 pounds and will only lift the from wheel off the ground. But you can take two fingers and lift the back of the deck and will raise fully and stay in place with engine off dropping only a inch in 3 hours. Sadly my 8n will lift is fine

Dealer change the filters and cleaned the intake screen. Also put in a new valve for a total of 1700, but still does not work.

Also will not pick a 10" post hole auger out of the ground half full.

But 410 loader will lift back end off the ground. Unweighted.

At my wits end has to be something simple that every one is over looking.

Also has 2440 pounds pressure.

With a hyd gage installed, what is the pressure when you try to lift a load?

You say the pressure shows 2440 psi, and that indicates the pump is probably working.

You only have two things left, and that is 3pt piston seals or valve. You did say that the dealer replaced the 3 pt valve.

Tell us the pressure when you lift a heavy load.
