I’ve greased all spindles and grease fittings, 2017 mower I bought it and it had 63 hrs on it, driveshaft coming out transaxle drives gearbox that drives belts
My Diesel zero turn mower runs great only
90 hrs engine hums along smoothly then deck slows down and almost stops in grass that’s a 1/2 “ and it’s not even thick blades are 2 weeks old belt looks great anyone had a similar problem
