I have a 917.270821 crafstman 42" cut 19.5hp mower. i have replaced the mandrel numerous times. I have replaced the blades and pulleys over the past few years. Long story short when i engage the blades on my mower the belt just burns in two. If i unhook the belt from the tractor the tractor runs fine. and as long as the blades arent engaged it runs fine. but as soon as i engage the blades the belt burns up. i can spin each pulley freely with my fingers. they are not bound up or anything. any ideas??????????????

This can be due to a belt slipping or a bad spindle bearing.
And on the difficulty scale,10 being extremely difficult, The belt would be a 1 or 2 and the spindle about 6 or 7 (because the deck usually needs removed for this job)

Check proper belt routing. These models are a little tricky. Also check tensioner spring.

Try pulling on the cable coming down to deck. This cable might be your problem. Also check that the spring on the end of this cable is present and functional.

sounds like either the spindal bearings are shot or maybe the spindal shaft is bent. check for up and down slop at the blades. then turn blades towards each other and check that the heigth lines up. also chec the idler pully to make sure it is not slapping around.

Did you obtain the correct replacement belt AND pulley. Double check your part numbers against the parts list for your machine. If you verify that they are correct, double check the belt routing, make sure it didn't get on the wrong side of a belt guide and is in the correct configuration. Look at your idler pulley and make sure the release spring is doing its job pulling it back from the applied position. Make sure that the arm for the pulley moves freely where it is bolted to the deck, it could be bound up with rust or debris. You should have a lot of slack in the belt when it is in the released position. If it does not then either it is the wrong part or improper installation
