JD 2520 Snapped Axle

[slowzuki]

I've used them and hooked things before, yes it can suck you down a bit and lift the front, but if it happened before the break there wouldn't be skid marks because when it hooks and sucks you down it stops the tractor.

Skid marks like that are from the tire locking up while the tractor was moving at a good clip.

you don't know that...if you have your three point with boxblade at a set level, and a tooth hooks something, it tries to pull the three point down, and fast for that matter.....

that could very easily be what happened. i've had it happen and it pulls the front end right in the air...fortunately i never broke anything major.

as far as the tires rubbing on three point arms, if your going forward and it catches that should make the tire want to go down, not up. that would break the final drive housing on the top first, so without seeing it first hand it is a little hard to tell.

You sure the tire "skidding" mark is from dragging and not spinning? If the rear wheel was spinning at a high rate of speed, the same imprint in the dirt would be made. Right?

I find it hard to believe using a box blade could cause this type of damage. IMHO the tractor had a flawed casting. Or is a poor design. Or the tractor has seen an abnormally high impact to the tire/wheel (dropping off a trailer, falling in a ditch, etc.).

How did that plastic netting get wrapped around the axles like that?

No if you look at the skid, the lines in the mud are straight. The tire was locked. If it was spinning it leaves spiral shaped lines, the curve of which can tell you the direction and speed of the spinning.

Does the 2520 have aluminum or cast iron housings?

I was wondering the same thing. I think some JD CUT have an aluminum center section. Did the bolts pull out of the aluminum or did it break or is the casting iron on this model JD?

i notice what looks like oil spots on the left tire,
would the right tire splatter it that much?
also, there is a pic where there is oil on the
front right tire, good sized spot, did it
splatter from the rear rotating around?
if so, how fast was that wheel spinning?(maybe
it broke traction and the wheel spun fast?) or was there
oil on the ground that didn't get noticed
and the tractor had driven over it?

they are all aluminum( axle housing and center housing) on these tractors. same for the 3x20 series....

Wonder if that may be part of the problem?

There's been a lot of Deere CUTs with those aluminum castings without breaking during use.
IIRC, there was a rash of breakages of the top link bracket several years ago. I think that was attributed to using the wrong link hole. Again, IIRC, this was mostly on the 4200 and 4300 tractors.

I don't find it hard to believe.

Nor do we know if a catastrophic impact happened that over stressed the casting at a time before the actual failure. Or even related to the previous failures or their repair. Many, many unknowns here.
