adjust hydraulics for loader

[mavrk]

DK35 when new a couple of years ago,i could pick up the front end by pushing the loader into the ground.it won`t do it any more,

is there an adjustment ???. i`m pushing wood poles into the ground with the loader and i can`t get the tractor weight on the bucket.

thanks george

Welcome to TBN

You can make a gauge setup for about $30 or so and test the PRV (pressure relief valve) pressure and see if it meets specs. Basically the gauge would plug into one of the loader ports, then you operate the joystick to activate that port and read the pressure.

Is the fluid clean/clear? Any evidence of water in the fluid (milky looking) or air (foamy)? When was the filter changed and the suction screen cleaned?

Picking up the front end requires much less than the 1600lb lift capacity of your loader. Are the other hydraulics on the tractor OK? Do you notice less lift capacity as well as lower "push" capacity on the loader? If you have a load a foot off the ground and shut the engine off, how long will the load stay off the ground? Kenny points out that the relief valve may be responsible but I was not aware that those need adjusting once set by the dealer initially (I just never heard of needing to adjust them in the field as a regular maintenance item but could be naive).

Just to be sure that the loader is not bottomed out, put the bucket in a dumping position before testing whether the machine can lift the tractor nose.

Does the joystick feel tight, or is there some slop before you feel it engaging? You might take a look at the cables going from the joystick to the valve incase they are loose or out of adjustment.

The "vital sign" tests for the Front Loader are a Pressure test and Leak-down test. You can tell a lot from these 2 simple tests. The pressure test should be done as previously posted. Perform the pressure test on both loader functions. Then you should also do a leak-down test.

Place the boom about 3 feet of the ground with the bucket bottom level to the ground. Meassure the cylinder rod stick-out on the boom and bucket cylinders. Place a bag of concrete or sand in the loader bucket (80lbs.). Every 15 minutes, re-measure the rod stick-out on the boom and bucket cylinders for 1hour.

With a pressure test and leak-down test, you can start to determine the health of the loader hydraulic system. You really need both tests.

He has an old style where the joystick is mounted on the loader.
We exchanged emails so he should be good to go!

Hey Rick, I have a number of problems in life and I'm wondering if exchanging a few emails with you would solve them too?

I think it would be best if you made a visit to my office!

I don't like the sounds of this!
