I recently purchased a fairly good shape Kubota G4200, after repairing some rust holes on the deck, servicing the various fluids and greasing every grease fitting on the mower I attempted to install the new PTO belts I had bought. https://www.amazon.com/gp/product/B08CQ4TZ2T/ref=ox_sc_act_title_1?smid=A1NOZYATA1STC0&psc=1 These are admittedly the cheapest ones I could find but I figured I would give them a chance. The issue I was running into was the belts were wanting to turn even when the PTO was off, so I checked and greased the PTO belt tensioner and it wasn't seized or anything and when in the off position it was letting of the belt. The "brakes" are all still in tact and present. So I loosened the adjuster until they weren't turning when the PTO was off, but then the problem I ran into was the belts were smoking and burning up rapidly when using them. I have the adjuster as loose as it realistically can go and they are still making noise when the PTO is off and when the PTO is on they are smoking badly and burning up, specifically the outer belt, one closest to the front of the mower. The inner belt lasted through 3/4 of an acre before shredding itself. Just really don't know what to do at this point. Here is what the pulleys and everything look like. Oh and yes I know the adjuster is broken, I am going to handle that eventually, honestly I am just asking for advice or the proper way to install these belts. All the pulleys move freely none are seized up, that's why I can't figure out why the belts are shredding themselves up. I also can't afford to pay Kubota's price tag for OEM belts if they are just going to burn up and shred themselves too.
