So I noticed a bunch of oil on my trailer where I park my Z-spray. I looked and the wheel motor was leaking. Damn! My machine is 13 months old now and just out of warranty. I called L.T. Rich to figure out how long this was going to take and how much $$ I was going to be out. What happened? Bottom line: I had a wheel motor here the next morning, with a hub already pressed on and ready to bolt up and go. It took me 5 minutes. Cost: $0 Brett said it had probably been leaking for over a month which put it into it's warranty period. The worst part is now I can't say, "I never service my machine at all." That is why I love my Z-spray.
