Loader not lifting front of tractor?

[VTSasquatch]

I am not sure that this is a problem but it seems almost every advertisement that I see for a used tractor shows the loader lifting the front of the machine. My loader won't lift it but otherwise seems okay. Is this a problem with the pump or is it just that some machines wont do it? Could this be related to my clutch problem (gears grinding thread)? Thanks

Is that with the bucket curled down, and it won't lift the front end? Or is the bucket curled up when it won't lift?

What tractor, not that it really makes any difference.

With the bucket curled down. It is a Massey Ferguson 220-4 (1980s model 30 hp).

It could be the cylinders are bypassing.

An oil pressure gauge hooked up at various points (kennyd has a handy gauge on a short hose with a QC for easy plugging in to different circuits) will help track down the pressure problem.

All loaders, if properly sized for the tractor, should be able to lift the
front wheels off the ground. That's a good test when evaluating a used
CUT.

If it does not, it could be one or both cylinder piston seals are leaking
too much, as JL says. If that is the case, lifting force should be better
if you rev the engine higher.

You could have pressure issues, as also noted. Sometimes the system
relief valve is set too low, or you have added a valve with its own RV,
set too low. Diagnosing with a guage is the only good way to test this.

Sit the buckett flat on the ground and then try to curl it and see if it will pick up the frontend like that most tractors u have to do that to

I agree.. if nothing else, the curl should lift the front end.

unless it's a real low pressure/low capacity loader.

i have seen some cut loaders with payload ratings around 700#'s

check pressure and check ratings ( ratings first.. )

What kind of setup do you have? Single acting cylinders on loader arms will not lift front end of tractor, even if you have dual on bucket.
Far as grinding when shifting, other tractors have used different methods to stop, or slow moving parts to make the shift smoother. Maybe just an adjustment.

Yup, my FIL has an old Ford with a home-made loader. The bucket has a double acting cylinder but the boom is single acting. The boom comes down with gravity only.
