Have a John Deere LT155 riding lawn mower that I am trying to repair.
The tractor runs, but when the transmission is engaged, the drive belt is forced off the pulleys by the transmission fan. I have posted a video demonstrating the problem.
It appears that the fan is sitting too close to the pulley, but I can't see how to adjust the height next to the drive belt pulley.
Anyone know what might be the problem? Is there something I can adjust? We bought a new transmission fan blade, but after I got in to see the problem closer I really don't think it will make a difference.
