Worth Family no it will not. It will not move but should still start. Check for spark and check for fuel. Let us know if it turns over and what symptoms your mower has. The more detail you provide, the greater the likelihood of getting a good answer.

My mower seems to have the same issue! I can drop the deck and it starts right up. Put the deck back on and the engine wont start. I have the belt on correct (v inside). It gives the impression when it try’s to start Raaaaaa the belt is not moving freely. I’m working on this alone I have no good way to watch it and keep the seat in contact. I have a fixed bracket for the pTO tensioner, and unsure it the tensioner is any good. I really feel this has something to do with the small idler pulley. The idler pulley bracket seem very loose maybe even bent. Any update on your tractor?
