Adding insult, and more injury......and a bit irony..............

The insight given was what tipped the scale. As I know I do not know everything I need to know, it helps to get ideas and insight from others' experience.

But after scales tipped, its a shame the others seem to force the issue that previous suggestion where not valid or short sighted.... Often trying to demean the responses of others...

Anybody ever know it the drain plug ever got removed in another thread after 200 or more pages of remarks?

By any chance, had you heated the end of the shaft to remove the nut & jumper? If so, you may have case hardened the shaft and it became brittle.

It had actually never been "off" before..

Can't help you with the broken shaft but as I enlarge your picture and scan the upper left corner I see a twisted wire in the field. Bob

Catvines or one of the other climbers, which are part of the reason we burn. I really think I'd just hit to many stumps over the years while mowing the thinned stands, something I will be more careful of heretofore.

Your brown cutter will be able to handle anything you throw at it, as you found the weak link in the MX cutter as has so many others with them.

Ummm... Don't think so... Blowing up image on 24 inch monitor only shows dirt and organic growth...

Now that is a thread that went off the deep end big time. I lost interest after about the first ten posts so i’m Assuming a bigger hammer and a chisel came to the rescue.

had this happen with a straight bevel gearbox, what happened is the straight bevel gears had enough play in them they float so much in the teeth they will internally lock up and the intertia of the blades and pto still stopping will shear the shaft - i ordered a new set of gears for my gearbox, oddly enough the replacements came as a spiral bevel - had to work with shim stock from the auto parts store to get the preload set properly but they have worked fine - took me about 2 hours to get apart, 4 to 6 hours to get all bearings/race metal fished out parts installed for fitment then had to get shim stock - i could have gotten an entire new gearbox but it still woul dhave had to be disassembled to replace on my tiller. No this was not a rotary mower but same principle.

took me another hour to get things like i wanted and bolted down and filled up with oil so 8 hours total - new gear box was 500ish - gears, bearing, shims, oil cost me less than 200 bucks

Aren't there shear pins built into these things? Or am I on the wrong track with this? I've never used a stump jumper, just an old 5 foot old, old M5 brush hog pulled by an even older 30 hp JD. When I mow a large field I carry along a coffee can full of shear pins & shear bolts. There's always some hidden trash, so It's not unusual to break a dozen bolts or more in an afternoon. The blades are getting beat up, but the gear box seems fine.

most of the time it wasn't a matter of hitting anything, they just weren't made correctly and just broke, back when I was still at a Deere dealer we had several thet just "fell off" as they were mowing, blades were perfect and showed no strike marks. It's really a shame, because it's one of the nicest build HD mowers out there were it not for this issue.
