Kubota L5740 3 Point hitch arm fall off

[chrissy28]

warning, not so great with mecanical terms.

I do snowblowing with inverted snowblower pull behind on L5740 Kubota tractor and the arm on right side keeps falling off dropping my blower. This is second year with tractor. Any body else have this problem and why. My mechanic says arms sloppy so it just falls off. Kubota is sending new arms etc.. but I would like to know for future why this happens. As I go around corner blowing snow into snow bank it comes off.

thanks

Don't know what you mean by falling off the blower.

Are the pins on the blower cat 1, and if so, are you using reducer bushings because the 5740 arms are cat 2.

Cat2 but that is not where it falls off.

There is a splinded shaft that goes through the top of the axle housing, that has a snap ring on each end. The snap ring on right falls off causing the shaft to move over which allows the link arm to fall off. The link arm attaches to the upper end of the lift cylinder. The upper end of the stabilizer link also attaches to the same arm. When the snap ring falls off the shaft moves to the left causing the upper link arm linkage to fall which causes the right side of the snowblower to drop.

Does this make sense?

Oh, Yezzz - it makes as much sense as the other recent threads on Kubota "quality".

sounds like the groove that the snapring sits in on the rockshaft has worn or the snapring is the wrong size, how old is your tractor?

The tractor is one year old.We put one snap ring on.It lasted 2 weeks. We await parts and hopefully just the shaft warn and just one of those things

Chrissy, I'm not familiar with your tractor, could you post pics of the problem shaft? With and without the arm on it.

Here it is with the arms attached.

We have a L5740 (with only 33 hrs), so we'll keep a close eye on the link. Until now we don't have any issues with the link.

Your post makes sense to me.

We do have an issue with starting the tractor. For about 10 seconds at start up the tractor sputters and emits white smoke. After 10 seconds it cleans up and runs fine. Does yours do this as well?

Your problem is that you don't have enough heat to get proper combustion at initial startup, hence the white smoke.

You either need to run the glowplugs a bit longer, or need to plug in the block heater (if so equipped). The bigger the engine, the tougher the cold starts. There are times on my 7.3L diesel that the glowplugs just can't get enough heat in there to avoid the white smoke and rough idle, or even keep the engine running for more than a few seconds - that's when I NEED the block heater.
