Hi all here's my problem . I brought a John Deere 165 hydro it ran great then one time mowing it came to a stop but was running fine .
So I looked to see what was wrong with it and the drive belt was off so after I got it in the garage and took the deck off . I put the belt back on and started it to see if it was on right nope it came off .
I then went to the internet to see if I had missed any thing . Well the mower was missing something . The drive belt was missing a whole pulley the one by the shaft that comes out of the engine . So I double checked it with the John Deere site the whole assembly was missing the bolt for the pulley .
So I went and walked where I had mowed to see if I could find any parts I found nothing . I got all the parts now this is where I went what the f as I had to undo the engine bolts to get the bolt in for the pulley .
The slot for the bolt was full of crap and looked like nothing had ever been there . So after fitting it I tried to start the mower and I think the belt was to tight and causing the engine to drag and not start . So I slacked it off and it started but the belt came off . Ive tried it so many time now I'm thinking may be I'm missing something with the belt . Now the belt is twisted would that cause it to come off
