I read recently in one of the posts about a deck washer that could be bought from Hoobers and installed on the deck of a mower. It requires a 13/16" hole to be drilled for it to be installed. I have been looking at pieces and parts in a McMaster-Carr catalog and I think I can do the same thing and have to drill only a 1/2" hole. My question is: Do you do the washing process with the blades running wide open or is this a gradual ramp up process to full speed? Is there any danger of damaging the blades or spindles? I was by my dealer the other day and I thought I saw some type of water hose connection in the deck of one of the Kobotas sitting on display. Is anyone familiar with this and have you ever used or installed one?
