That made me feel better.

I bent both upper hydraulic shafts on my tractor this week and wondered how I did it because I was just loading brush and branches, no dirt work.
I guess I dive in the pile <snip>

I had a JD 4010 (70ish hp) with a JD 157 loader. The rams connected directly into the back of the bucket...neat; had 2 rigid and 2 floating pins to capture to mount the bucket to the loader (great sport working alone as I do)....which was also used with a hay fork requiring swapping frequently. I was digging out a pond and was using the bucket in the vertical position to breakup the soil so that I could load and remove it.....bent both shafts.

Just got them back. Two bent shafts and they had to manufacture a new threaded collar as mine had a hairline crack in it.
Straightened the shafts, repacked them both re chromed the shafts, made a new collar $960.00 and a week down time.

My advice never even move your tractor if the bucket shafts are extended 100%. Seems that is when they are the weakest, and on mine only 1-1/2" Kubota 4060 so no more for me.

I think I figured out what I did. I was loading a dump trailer with brush and a grappler. I tilted the grappler all the way down and used that to "hammer" down the brush in the trailer to condense it. That hammering is what bent the shafts with the grappler 100% extended.

Note to self - don't hammer with FEL, it's a loader, not a hammer.
