Centering a front end loader

[nyone]

I took the tractor for a shakedown ride. Unfortunately, the arms shifted back to the left, so nothing was gained

That's what I would expect.
Are your tires inflated the same? Can you measure the rear axle height at each axle? I have seen two of the same brand, age and size of tire 1in bigger than the other.

Now that you mention it, the rear tires are mismatched. I'm casually looking around for a decent price for new ones.

I just worked the loader for three hours moving sand that blew into a fence line last summer. It works fine so I'll just learn to live with the whopper jawed look. I did figure out a way to level the arms that would be a lot easier than cutting and leveling the front support. It might involve an hours' time but I decided that I have more important things to do, mainly the work that I bought the tractor for.

Yep, as a quick temporary fix,
If the Rear tires are mismatched try elevating the pressure on the buckets low side and slightly lower the other Rear side pressure , may be able to get the bucket flat with just air pressure adjustment. Front tires will have no effect.

For the loader lift assembly to be off center one of two things has to be off.
1. The loader lift frame is not parallel. bent, this would be revealed by measuring the frame in an X pattern, say from the mounting (top pivot) pins to the same point on the opposite side at a point on the front. Crossbar, top of "knee" or other location.
2 One side of the mounting frame is "front" further than the other. Measure from a known location (front axle, rear axle, same spot of the frame on both sides) to the same spot on the mounting brackets.
Rear tire size, hydraulic cylinders (Unless one is longer than the other) will have no effect on the frame to tractor spacing.
Mismatched rear tires will cause the bucket to touch one side before the other And wear the cutting edge quicker on the lower side.

That is good information. I haven't put a tape measure on the frame yet as I assumed that since it is bolted into holes drilled into the casting at the factory, the back end of the frame will be what it is. It really is rather massive for the size of the tractor that it's mounted to. Nothing appears to be bent that wasn't bent in the manufacture of the loader. I did level the front support. It's been so hot outside that I've not had the motivation to look any deeper. Once the weather cools down, I'll take some time to do some measurements to see what that will reveal.

possibly the torsion cross bar is slightly twisted. did you by chance lift loads with one side connected & the other side disconnected to the bucket? had the same issue on mine once when one side of the bucket unknowingly became disconnected lifting loads. there are techniques to re straighten the connecting torsion bar, will let someone else recommend.
i wouldn't be cutting & rewelding just yet. good luck

I've only owned the tractor for nine days. Just like marrying a divorced woman, I have no idea what abuse has taken place. I have no intention of cutting anything until my new rear tires arrive and are mounted. I used the loader for a couple of hours this morning and had a good chance to look it over from the driver's seat. It definitely is higher on the right side at the front support. Once I get the new tires on it, I'll put it on a level slab and measure up to the bottom of the rear supports on each side. Casual observation shows the mounting plates to be drilled near identical, judging from the distance beneath the bolt heads to the bottom of the plate.

But with a tractor, discovering the results of said abuse is much less exciting, good or bad.
