Today I pulled the tractor up to the garage to install a new drive belt. That's not the interesting part.
When I put it back in the shed I got between the tractor and back blade to put a maintainer on the battery (it might be a long time before the tractor is used again). After the maintainer was connected I plugged it in.
Apparently plugging in the maintainer caused me to forget about the back blade. When I exited the shed I failed to step over the blade and tumbled over it. I skinned my shin real good going over then banged my knee very hard on the frozen ground. I'll be limping for a few days.
