Default 1650 PTO question

I have a 1650 Hydro that has been in the family since it was new in the 70s. Just recently, the front PTO that runs the mower deck just cuts out. Now it will run the deck for 20 sec to as long as 3 - 4 minutes when the unit is just started, but then cuts out again. This has an electric switch that activates it. Sounds like an electrical problem, but it all looks ok from a visual inspection. Could the air gap adjustments on the front clutch be connected to this issue? Does anyone have any experience with this problem? Thanks.

It sounds like the air gap is you problem to me. The pto will act intermitten like that if the air gap gets to big. I believe the correct gap is .017". I might be wrong on that, but that was what it was on the x82 series I've worked on. It shouldn't be a hard fix.

Default problem solved

The gap adjustment was only off a little, so I adjusted it and the problem persisted. Then I was able to isolate a cracked wire going to the PTO, so that was the final fix. Thanks for the advice.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
