B21 Backhoe Ground Rules

Hello all. I have seen a few post regarding proper operation of a backhoe but nothing specific to what I have done. Yesterday, I had my hoe extended and hooked around a 3x3x8 piece of concrete. I got carried away and rocked the machine to get the concrete to budge. Once unseated, I pulled it with the extended hoe, about 30 foot to its final resting place. Once done, I was moving my tractor into my shop that is up a hill. I heard a popping sound followed by grinding. I think I have destroyed my differential and plan on a tear down in a few days. Sitting here thinking about it, even though great leverage, it obviously multiplied the torque in the differential to disastrous level. Have I broke one of the -Thou Shalt Not- rules of backhoe operation and was just unaware of it? Thoughts on my stupidity? I did find a post about a B21 differential tear down which will be invaluable in the coming days. I might try to document mine for the benefit of others. Thanks for the wonderful site and resource.

Most backhoe operations are done with the stabilizers down, bucket down and all the wheels in the air.

Despite my very limited experience, I would say both of those are NOTs.

I do not, what is KTAC?

I just looked it up. Unfortunately it excludes breakdowns! But it does cover a range of things. Thanks for the reply

It is damage insurance from Kubota mostly purchased when financing through Kubota.

Whether your situation would be covered is questionable, however reports indicate they cover many questionable issues.

Assuming you are out of factory warranty or the warranty claim is denied.

KTAC Insurance Agency - Default

Were you pulling the tractor with the stabilizers up or using the tractor to pull with the backhoe boom being the anchor?

The backhoe was extended as a hook and the anchors were up. The tractor was not being pulled, it was under its own power.

I wouldn’t think that would hurt anything on the tractor. It’s not good for the backhoe but the tractor is still limited by its own power.
