@Bar Nuthin related PTO MULE DRIVE pulleys are also a very important part of that , personally repacked mule drive bearings , easy also go after pto cone drive , needle bearing ( clean out , regrease , hi temp grease ) LUCAS GREEN CHASSIS , outer sealed bearing , NAPA , that entire set up can / should , move easily by hand at pto to deck , down slope , a screaming belt clutch is telling you of bearing related problems , its the functional detailing / verifying , smooth easy belt drive , that is what you want , pete
