New TYM 2515R review

[ptsg]

Nothing was on the 3pt hitch. Once on the hill, the only way to continue up it was to use 4x4, because rear drive only resulted in sitting there with the loud noise and vibration in the rear end. Going down hill and on level ground I didn't need 4x4.

Did you check both rear tires once it reached the point it wouldn't move? Were those spinning? Both sides? Almost looks like it was just tire spin.

Or maybe the rim spinning inside the tire.

So the dealer cannot recreate it, and they looked in the rear end and found nothing?

Can they recreate the circumstances you were driving in?

I'm wondering about wheels spinning in the rims now too. Were you certain the rear axle wasn't turning?

Op. Mark the wheel tire alignments both sides and recheck would not be the first time a tubeless tire rotated on a tractor rim under power.

I guess that's possible...but every time the problem occurred, there was a significant vibration, too, like something mechanical slipping, ratcheting, or grinding.

In any case, I don't have the tractor, so I can't test it.

I dont think it's a tire vs rim issue, I think it sounds like an axle shaft kinda issue

Also, after it happened the first time, I again attempted to climb the hill and again it wouldn't move due to whatever issue it was. So, on the third try, I locked the rear, thinking it might help and nope, same thing again, so I doubt BOTH tires were spinning on their respective rims.

 

[paulsharvey]

I dont think it can be clutch, because you had plenty of drive on the fronts to pull yourself up hill; I highly doubt the tire slipping. And you tried locking the diff, so now, I'm thinking it's in the diff

 

[K5lwq]

I wonder what the dealer meant by they tore into it? Did they drain the hydraulic fluid before tearing into it? If so, did they inspect for metal in the fluid?

Do you have liquid ballast in the rear tires? If so, what was used and how much air pressure are you using behind the liquid?

I’m struggling to understand what could fail in the differential that would cause this scenario. I would think there would be noise or something regardless if it was under load or not. Just rotating would yield some noise I would think.

 

[paulsharvey]

Without a detailed schematic of the rear axle and differential, it's hard to say. Maybe under load, the axle stubs are able to shift outward, and have little engagement with the diff gears, causing the noise, and the lack of drive. That would clearly be a manufacturing problem, as the axle shouldn't be able to shift, and also, a 2515 should have an axle plenty strong enough for a 4515 or whatever it is, 4715, I don't know the TYM models that well.
