LA302 Loader

[Jim Ingram]

Having trouble with LA302 loader joystick sticking when lowering, any help?

Is it cold?
Could be trapped water in the detent freezing.
You can remove the cover and clean it out on most models.
I would have to see a picture of the valve to give better info, as that loader came with 4 different valves.

If you’ve put quite a few hours on it my apologies for potentially insulting your skill level with the machine but you’ll probably get this from someone and it is the simplest answer if the machine is new to you.

If you push the joystick all the way forward to lower, there’s a detent that puts it into float. If you push forward carefully, you should feel a little bit of a bump in the stick as it goes past the detent. Once it goes past the detent it will stay full forward in float until you pull it back to pull it past the detent.

In the past some operators new to this feature who tend to lower very quickly in their operation have reported this as “sticking”. With the engine off and bucket on the ground you should be able to play with it just to get the feel of the detent if you aren’t already familiar with it.

If it isn’t that, I’d follow up on Wolfman’s questions.

Yes it is new to me and I have used loaders with this feature however I was not aware this loader had that feature. This is on a B7510 and it has 319 hr. on the tractor the valve is a B01303 if that helps. Also I have been playing around with it this morning and noticed it does not have the downward force it did have it will not lift the front end off the ground. The lift upward does not seem effected, it lifts the rear with a 6 ft box blade quickly.

This is where a pressure gauge is invaluable. You get numbers not vague perceptions. So now you have no down pressure but its no longer sticking?

Thanks for your reply. Sorry if I was not clear but yes the float/stick is still there. It seems the last 4 inches travel of the cylinders does not have enough pressure to raise the front of the tractor. Laying 4 x 4 blocks under the bucket it will not lift the tires, however lowering the bucket flat on the ground or on the blocks and curling the bucket it will lift the wheels. You are certainly having the correct tools would certainly help.

I don't expect this will help at all, but I will say that I have noticed lack of lift on my loader depending on what was going on in the rear of the tractor.

For example, if I have the backhoe on, and the stabilizers down, the front loader will not lift the front of the tractor.

If there is something heavy hanging on the 3PH arms, and off the ground the front lifts without much effort.

Point is, when you are comparing to past experience, try to make sure you are comparing apples to apples, and no oranges come into play.

Like I said, probably no help but just something I observed at my end over the years.

Thanks again for the reply. Only thing on the rear is the box blade sitting on the ground. I have some experience with a JD 4100 for a couple months and years with larger tractors but not much with these small tractors. I just got this one to use around the place. Finding out at my age I can't do what I use to. Thanks again.

If it won't lift the front with blocks under the bucket you are getting little or no downpressure from the boom cylinders.

When you dump the bucket the bucket cylinders are doing the lifting. All the boom cylinders are doing is locking the boom down. The fact that they hold rules out the possibility the valve is stuck in float.

Get yourself a pressure gauge and start measuring pressures. Also make sure the 3pt is fully lowered. It can block the loader cylinders if it is out of adjustment.

I do not know the geometry, but just for fun lift the box blade off the ground and see if there is a difference. I imagine their should be. If not this might become a data point too.

Just a thought...
