JS45 &JS36 self propelled mowers. Both have Briggs motors, run fine and cut fine. The 36 is all good, new blade and fresh oil change. The 45 was running fast and the drive belt was wearing - in the middle of replacing the belt and messing with a new drive cable. Not a complicated fix but haven’t had the time to mess with it. Lot of interchangeable parts between the two, they have the mow-mentum variable speed drive system. OBO, open to trades.
