There are a few bruises on the corners of my buildings. I have sliced and diced more lengths of garden hose than I care to tally. Kong dog toys exit a finish mower at an exciting velocity. I've electrified the whole tractor mowing too close to the electric fence. I was diligently leveling out some lumpy spots near the edge of the yard but I had forgotten about the black currant seedlings we had just transplanted right behind me - I back-dragged the loader right over them.
No damage to anything other than my pride - I was on an older Craftsman ride-on which had a 3-speed transmission. The shifter was in the middle of the platform in front of the seat. I hopped off to clear some debris from my path and hooked my pant leg on the shifter thus power shifting it into 3rd gear. It was plenty fast enough to make catching up a significant challenge. Of course, the neighbors were entertaining guests at the time and they were outside to witness the event. I got a round of applause.
Jusy been reading through this thread, only up to Post No 83,

but I'm just now able to stop laughing - so much so I've still got tears of laughter streaming down my face :laughing: :laughing: imagining those scenes!
To add my :2cents: I've only had two significant accidents - both as a young teenager. First one was refuelling our much-loved MF35 from an overhead 500gallon tank on a tripod frame (they are now outlawed - no prizes for guessing why). After filling up and hanging up the hose, looking rearward I reversed away. I felt something strange and turned my head just in time to see the tank falling toward the tractor.

Fortunately I was out of reach, but the tank tore the exhaust off, glanced off the bonnet and front wheel onto its side on the ground, diesel running out of the vent at the top of it. I jumped off and covered the vent with my hand until we could unscrew it and plug the hole. The tank had a huge dent in its side, but I reckon I was lucky I didn't get squashed. We found the hose had inadvertently looped around a length of heavy railway track across the front of the tractor. Next day Dad got a nearby road repair crew to stand it up again with their loader.
The other silly mistake - leaving our MF135 idling while I jumped off to grab some tools from near an irrigation pump engine.

Not applying the park brake, it rolled away, and went upside down into about an 8ft deep waterhole in the creek. We rolled it right way up and fished it out with the 35, then got it repaired. I was too young to repair it myself - I remember in 1975 it costing my parents $600 in repairs.
As someone else already stated - when you pay your own repair costs,

damage is dramatically reduced. Only mistake I've made recently :ashamed: is reversing and putting a rear tyre into the door of our 300E - whilst watching the bucket doesn't damage anything! :confused2: Again, as already stated, watching one end instead of the other!
(Edit): I reckon though,

the best so far is Post No 132 :drink:
