Default Cub Cadet 129 Mower Clutch
Hello everyone!

Excited to announce that after having my cylinder head resurfaced, installing a new head gasket, and re-setting the timing (according to Matt's procedure found on this website) my little 1973 model 129 is running and starting much, much better, even considering the large amount of blow-by.

Anyway, now that I have the cub starting and running more reliably, I want to get the mower deck back on it before winter comes so I can test it out! As of right now, the clutch on the front of the engine is stuck, so I disconnected the linkage so I could start and run the machine without the pad slowing everything down.

So my question is, since I've never worked on one of these types of clutches before, is there an easy way to get one freed up, or is it possible to buy an electric one like is on the newer machines? My dad said those mechanical ones never did work very well, and so I thought it might just be easiest to buy an electric one if possible.


Thanks for your help! This site has already helped a bunch!

Calvin

Do you mean it is always turning? Is there a belt connected to the pulley? Check the pto wear button? maybe it is too worn and not engaging the clutch?

Not sure if you can get an electric one or not, but the mechanical pto isn't that hard to rebuild. There are several threads here for guidance. I rebuilt my pto a few months ago and posted on it. The one thing that stands out to me is that there was a long and short set screw in each hole holding the pto on the shaft.

The engine block has to have the "mounting bosses" cast into it along with being drilled and tapped for an Elec PTO. The 129 has no such provision.

A suggestion, pull the Mech PTO clean it up, and rebuild it.

Service procedure for the PTO is in this manual.

They are not all that bad to work on. Did my first one a couple months ago on my 149.

Okay, thanks everyone. The manual will help a lot I'm sure. Do I have to pull the motor to work on it?

No but it is easier if you remove the grill.

The mechanical ones work great IMO.......rebuild yours and it should be just fine for years.

I agree, I'd much rather have a mechanical PTO. Actually the electric PTO ( among many other things ) is what keeps me away from a ql tractor.

The mechanical seems pretty simple once you get it off.

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.
