I have done way too many dumb things to even begin to try to list the majority here. Here is a small sample...
I have had my Kubota on every two wheel combination possible, some multiple times. Learned not to turn sharp with a really heavy load on the palet forks (few hundred T-posts) as the change in front end geometry tries to make the tractor roll over when the rear wheels come off the ground. I keep one hand on (guarding) the joy stick so I can dump the load quickly if needed (only 8-10 times so far.)
Don't mow too close to the fence on the uphill side as you can slip sideways a tad and let the bush hog get under the fence and then you can't turn to get away. I pulled the sway control pins and found that I could "bounce" the mower deck down hill and then shove it uphill and clear the T-post and drive nearly straight ahead and get away BUT... how to do that and drive at the same time? I foulnd a downed pecan limb only a few hundred yds away that was just barely strong enough to prop te dick to the high side and after a few attempts got it wedged with the deck high enough to clear the fence post. I drove slowly forward and got away, clearing the fence at a very slight angle and luckily not slipping.
I drove the cab model Kubota under a tree with limbs lower than the tractor roof and customized the top. I drove by a tree and the fold away mirrors folded but let a limb slap a back window. Boy that tempered glass sure EXPLODES. Backed into a limb... Boy that tempered glass sure explodes, every time!
"E" on the gauge must mean empty, especially if you drive on an incline.
If after having an engine cover fall off while brush hogging a little too enthusiastically and running over it, beating it out so it worked and then laying it down beside the tractor and runing over it again to get more body work practice.
I am on my 4th fuel tank cap. Only 3 count. Why doesn't Kubota put a keeper leash on the cap? (Because it is such a profitable item at about $20 or so a copy.) After losing the original and the first replacement I drilled a hole in #3 to tether it. Then the tank went bad and a new cap came with the new tank. I need to remember to take the new cap off before I lose it and put the one with the leash on it into service.
Brush hogged too close to my moms house after lifting the FEL high overhead to get clearance to make a particular turn in fear of hitting her siding. I missed the siding just fine but hit the soffit. That aluminum PVC coil isn't all that tough to work with and I had some scraps from when the house was built.
One of these days I really do need to make a mod to my trailer so that the one out of three times I put the tractor on it or remove it the ramps don't kick up and then miss their groove falling back and leave me sort of in a weird position.
I lowered the scarifier teeth on my box blade, shifted to low range, ran the RPM up tpo PTO speed (2600) and went at a piece of wire cable sticing out of a newly scraped place in the back yard. Yanked me to an instant stop, doing only mild chiropractic to my neck against the roof (Kubotas were designed to fit little people, not 6'2" 250 lb types.) I could have tested it with my FEL but no... just go for the gusto. I dug up 2 cu yds of dirt and removed a hundred feet of cable, alternator, truck leaf spring, fence posts, barbed wire, most of a washing machine, and so on. Seveal hundred pounds of debris. Previous owner had BIG dozers and apparenly burried some scrap metal. After I did some landscaping excavation (removed 4-5 feet to get drainage away from walkout basement.) Luck of draw, I found his dump site (In my "now" back yard.) Maybe next time I will test with the FEL and not assume a little piece of scrap could be dislodged by a few thousand pounds of moving steel (Kubota.)
I was just getting warmed up but have to go take care of some things.
