G'day Guys and Gals I have recently bought a 2001 Scag Turf Tiger 25hp 52 inch deck. In long grass of 1 foot or more that is thick and matted, the grass wraps around the driveshaft and then works its way into the seal of the cutter deck gearbox and breaks the seal and leaks oil. I have already replaced one gearbox because of this and then 3 hours later it started to leak again. I have only had the machine for 40 hours after buying 2nd hand. Has anyone had a similiar problem of grass wrapping the driveshaft and then subsequently damaging the cutter deck gearbox seal.?? Is this a common problem with driveshaft driven machines.?? Any help appreciated.
