Default Cub Cadet LT 2180 PTO Belt Problem
I have a 2180 with PTO belt problems that I posted about a month or so ago. The problem is still there, but I have had an idea that I would like to run by the brain trust on here, as a sanity check, if nothing else.

I put (yet another) PTO belt on it today. I mowed with it for about 5 or 6 minutes and checked the new belt. It was HOT. It was so hot I could not keep my hand on it. It is not rubbing anywhere. The two idler pulleys below the drive pulley were replaced last year. The blades spin freely. The pulleys all line up as they are supposed to. All the factory heat shields are in place around the muffler. I'm running out of hair to pull out.

While I was finishing the yard with my 50+ year old 123, I had an idea. Here is where I need somebody with more experience than I have to chime in and tell me if I am crazy:

Could the electric PTO clutch be slipping and transmitting that heat to the belt? It seems to be working, but where else could all that heat be coming from?

Then the follow up: how hard and expensive is it to replace the electric PTO clutch? It's on an 18 horse B&S 2 cylinder.

OK, have at it. Am I crazy, or just delirious with frustration?

The Wife wants to send it down the road and buy a cheap big box special from Lowes, but I don't want one of those. If I don't come up with an answer soon, she is going to get her way, and we can't have that.

My old friend had a similar situation, said his wife mentioned either the cub goes or she does.
He loaded the cub in the pickup and dropped her off at Walmart while on the way to the car wash.
He says sometimes he has long conversations with his cub.

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.
