One day I was driving my tractor past the boat ramp and decided to stop and rinse her off. Up till then I used the HST pedals as brakes. Unfortunately a new hydraulic hose may have interfered with the shift lever and she popped out of gear. I flailed away on the HST pedals until my pants were wet.

Then I found the brake. Once people stopped laughing they came over and helped me out. Then they left and continued to laugh out of earshot.

I rebuilt my first diesel engine that summer.
Since then I use the brake to stop and I clean my tractor with a broom.
