L3240 with LA724 loader hydraulic issue

[rkubota]

I have a L3240 FST 4wd with a LA724 loader. The tractor has just over 500 hours on it. The hydraulic fluid and filter was changed around 400hours. I have 2 issues going on which are probably related. Hope someone on here can help keep me from having to haul it into the Kubota dealer and spend a fortune. The fluids are at proper level and proper Kubota UDT fluid. My loader seems to have lost a lot of it's lift power, especially when curling the bucket. In the past if I was to ever get stuck in mud, I could put the tractor in reverse and curl the bucket to walk myself out of the stuck situation. Now the tractor will barely do this.
The 2nd issue I noticed is if you lift the 3 point hitch lever to the highest position it will put a bind on the motor, bogging it down some and limit the power steering and front end loader power. If anyone has an idea of what the heck has happened, please chirp in. Much appreciated.

Sounds like when the 3pt is lifted to the top it's going to far and is opening the relief valve which in turn will take power away from the other hyd functions. May need to either adjust the stop at the top of the 3pt control or adjust the feed back rod for the 3pt. Just to see if that's whats wrong raise the control to the top and then let it down just a little to see if it functions as it should.

ok, I will look for that adjustment rod. Thanks for the advice.

Yes, adjust the feedback rod first! Seen more than a couple combine a misadjusted feedback link rod with bouncing around with a load on the 3 point, causing the entire rear part of the transmission to break ($$$).

The loader issue might "fix itself" once the feedback is adjusted properly.
