Yes, very big varmits, ones that drink excess alcohol and borrow your tractor. Reality is the bell housing was all ready broken from bush hog brand loader brackets vibrating loose and then loader pushing heavy, kinda fulcrum type action. This is my second time to see the exact same problem on my kubota's. L3600 and L3710, both have bush hog brand loaders. The block... Not my doing, but it still happened, was placed on steep hill pulling, got stuck, person reportedly was trying to get it out by bucking, etc. started knocking, person there told the operator to run it anyway, then bang, the rest is history. Now I'm holding the bag to get it running again, but I will and with a bigger engine too. I just can't see how it came apart with 1100 hours, service was always up to date, every fluid and filter clean as new, even the engine oil I drained looked good, I guess dry sump on the hill or bucking just broke the crank or connecting rod? I will tear it down after I get new engine in and I'll know.
