We had another complicated repair to make recently on the Kubota front mower used to mow slopes and uneven terrain with a flexible Lastec deck. It is an important machine as our other mowers with flat decks scalp the turf around the greens, tees, and bunkers. The machine was leaking fluid from a gasket on the hydrostatic transmission (HST). Normally, gasket changes are not that difficult, but on this machine the bolts needed to remove the transmission housing are located inside the tractor. The only way to access them is to separate the tractor completely and remove the transmission.
Here are some interesting pictures from the process:

The mower is now back together and working. Older machines are always an adventure. When I was researching this repair, I did not find much on the internet related to it. Luckily, I did have the workshop manual for this piece of equipment which was a pretty good guide. I share these photos because, first, they are pretty neat to look at (if you like machines), and, second, they might help another grounds crew or mechanic needing to do a similar repair.
