I have a 17.5 Hp sears riding lawn tractor. The blades will not engage. I have cleaned the top of the mowing deck but still nothing.
Model 917258862 mower was given to me. sat outside numerous years. I've managed to get it to start run and drive, but cant get blades to engage. don't know what the wires are for or do that go to some sort of pulley attached to the bottom of motor. can somebody help me pls ?
I have a Craftsman DLS 3500 and the blades would not engage. I don't know the proper names but there are parts that stop the belt when you disengage. Look at the pulley system and engage and disengage several times with engine off. My mower would not engage becuase the part that stopped the belt would not let it go. I backed off the nut at that pulley just a little and it let go and allowed the belt to engage. If the nut is completely tight the brake on the pulley will not let go and thus it will not engage.
I added picture. The yellow arrows point to one of the pulleys that are too tight. Get a helper and engage/disengage the arm on outside you use when operating and loose one of the two pulleys just a little. You will see when the belt is released. Leave it as tight as you can with it working properly.

Is the belt spinning & smoking when blades are engaged or the belt won't spin if the belt spins but blades wont go then there is something stuck under the deck or the bearings are gone out do to not being greased
