Crack in JD rear discs!

[Acke]

Today I put dualwheels on for N spreading on wheats. And found out that there are a crack between boltholes! It is a JD6170 M with 2100hours . There are 650/65 42 with welded discs. Are this a often happens?

Jd wheels have been cracking up since 10 series!

ps at least they don’t fall off like they use to ?

Somebody I know has had this happen to his M series, not that old either.

Just because you can make a huge press to bend to shape the 10mm wheel centres doesn't mean you should.
The sharp bend leaves micro cracks which get bigger.
MF had the same problem.

Have you got the heavy duty rims to take duals ?

There is only about 3 main manufactures of agricultural wheel rims so I would expect a few to have seen it

Im happy found out to fix new rims instead of break down in field with 3000 kg feritilizer in spinner!

The centre will be about 30mm thick if not more basically a big thick plate welded in from the factory to strengthen them to take duals

This is the fix !!

Genuine Deere parts,happened to a mates tractor using Lely 3.2m mounted moco.Bit of a nightmare if you want to take the wheel off tho.

A 3.2m moco was enough load to cause that? Crikey! I don't expect that to happen to the 42" rims on the back of my tractor. Maybe I should take a closer look.

You only get three wheel drive on a JD so you surely don't need all 4 anyway.

What's with having flange axles on tractors?
Go with bar axles and steel center disc

It’s not an option on a lot of models here

I do not like the look of that, if it was in warranty I would require a new wheel

Or 2, and the kits.
