I stopped by the local Kubota dealer this afternoon to pick up the rear wiper and defrost kit for the M6060 that I ordered a few weeks ago.  I opened the boxes to make sure nothing was missing or broken.  There are a lot of parts in the kit including three pieces of glass, a new higher amperage alternator, alternator belt and mounting bracket, glass seals, wiper motor, wiper and blade, reservoir tubing, wiper switch, defrost switch and a few wiring harnesses.  Seems like a lot of parts for the money. 
I noticed the lights changing brightness a few weeks ago when pulling my neighbor's vehicles out of the ditch. I had front and rear work lights on as well as the regular lights, and when I reduced the rpm the output from the lights was reduced.  The standard alternator was having a hard time keeping up with the demand.  Perhaps this new alternator will be better in that regard. 
The dog didn't come with the kit.
