I'm glad your not telling us this from a hospital bed. Thank you for the reminder.
Glad you're ok. Thanks for having the forthought to post this. I always set my brake but last month I remember a time I didn't. Nothing happened but that isn't the point.
Sometimes when I exit the cab the door handle can catch my left jacket pocket. This makes me think what could happen if I left the throttle up, gear selector engaged and somehow hit the shuttle lever exiting the cab...
Lazy + Uncautious = Mishap
When I dismount out of my cab I often hit the range select lever out of B into neutral. Not a problem if the gear shift on the right is in park where it belongs. Funny that they can put a good solid park position in a manual shift tractor but they don't seem to be able to do that for a manual pick up truck or car.
Does your tractor not cut off if the brake isnt applied? Mine will shut down if the gear selector isnt in N and the parking brake is on, sorta like a little garden tractor.
I had my old Yanmar take off down a small hill once. It had blown a FEL hose, so I lowered the FEL, left the tractor in gear and killed the engine. I got out my wrenches, removed the hose and was walking away when I heard the tractor start to move, just a couple of little creaks in the tranny at first then away it went. As I watched the tractor started slowly to roll backward and ended up rolling all the way to the bottom of the hill. What I didnt know about the hydraulic clutch (it had a powershift transmission) was that the hydraulic pressure would bleed off after a few minutes with the engine off and then it disengaged so it was then like it was clutched. You also couldnt pull start it due to this issue as I discovered later. Luckily for me, there was nothing in the way so I just let it roll to a stop about 60 feet away. From then on, I tilted the FEL blade down and set it with the wheels off the ground when I stopped if not on level ground. It did have brake locks but the lever was a bit hard for me to reach to release it while pushing the brakes so it didnt get used much.
This reminds me of one time I was clearing snow at a friend's house. There's a gate with an electric fence wire across the opening, which I wanted to go through. Got off the tractor, idling in neutral, and no brake on. The ground is pretty flat, but apparently not zero grade.. just as I was reaching for the handle on the electric wire I felt the edge of the bucket (waist height) press into my back and push me into the wire! I don't know exactly how many volts the **** fencer puts out, but it's no wonder the horses don't mess with it. After getting that across the chest for about 5 pulses, I always drop the bucket and quite often set the brake now.
That's with a geared transmission, I'd be more cautious with an HST tractor.
