Tiny tractor: More rototiller repair, taking it apart to replace a bearing housing. These jobs either go fast or take exactly 5x as long as your worst case expectation because of little snags. (It would be quicker if I did this stuff all the time!) Here, I’m fixing the chain, a straightforward mission that involves lots of little nuts and bolts (remove and replace the housing) and a lot of grease. The caulking gun is for running a bead of silicone to between the two halves of the housing to seal it up. Concrete blocks and cardboard make a surprisingly workable instant workshop.
