Does anyone have a manual for this tiller? I am in need of a manual and need some felt seals for the gearbox. I have emailed Toro and am awaiting a reply. I was thinking about replacing the felt seals with rubber o-rings. Has anyone done this? I am just trying to bring this tiller back to its youth. Put a 6.5 horse engine on it and it runs great. After 5 hours of use the seals started leaking. Also, anyone know what year this tiller was made? Thanks in advance, Darin
