Cub 149 front PTO engaged at all times..why?
 

I'm new here so please forgive my technical ignorance.

A relative gave me his old 149 with a mower, tiller, cycle cutter, snow blower and single forrow plow. All implements need work, but that's late. This relative he just got tired of repairing it. I think he will regret that someday. I have had it running using the lawnmower for several years. There are problems that I am fixing one at a time. I'm not a mechanic, so I have to do my homework before starting any repairs.

My current issue is the front PTO is engaged at all times. I start the tractor and the mower is instantly running. I wasn't so concerned if I was the only one around the tractor. All of a sudden I have 3 grand kids that like to be around grandpa when he's running any machine. It's a safety thing.

I don't know if its a clutch bearing or what it could be. I also have read, but don't know, if I have a with or without brake type clutch. I've attached a .jpg image.

My machine is a 149 serial number 2050047u467251. I'm told the serial number is the second number, built April 1973.

I forgot to.mention ...its a 14 hp kholer... k321a I think.

First, welcome to OCC....... :Welcome2:

Yes, the 149 has a 14HP engine, hence the "14"9.

First thing I would check is the PTO bearing. Pull the PTO lever to "disengage" the PTO. There should be a gap in the clutch plates, if not adjust for same. The PTO should be free wheeling. If not, replace the bearing.

NO, your PTO is not the Brake type.

See link.......... PTO

Thankyou Roland for responding... I do not see any spacing in the clutch plates. I pull the lever and basically nothing moves on the clutch
The only thing the lever is doing is pressing the buttons together. Am I essentially rebuilding the clutch ...if yes what parts should I order?

It appears that someone put some type of adjustable button on your lever. Does it actually make enough pressure to push the center of the pto inward??
The rod is also adjustable...

Try adjusting the linkage.
When the lever is pulled back it should compress the spring enough so you can turn the very front plate by hand.
The clutch soring itself may/could also be adjusted incorrectly.
There is a gage that is to be used when rebuilding these units so it is adjusted correctly using the 1/4" nuts and a jam nut on each of the 3 "special" screws that hold the ass'y together.
Unfortunately , these nuts on the screws can only be accessed by removing the clutch from the engine.

I'm back home in Ottawa ontario canada and the tractor is at the cottage at Round Lake... u r probably correct in saying someone has made a part addition that isnt a cub cadet part. ill try to adjust the turnbuckle when I get back there next weekend. Removing the clutch is in my future but not until the grass goes dormant. I'm very grateful for your ideas. This weekend I installed 2 new mule drive bearing and a new mower v belt. One issue at a time. Thanks again.

I would like to order the pto bearing and the front pto rebuild kit.... the type b without brake version. Can someone tell me where I can find part numbers or better still, tell what they are...thankyou in advance.

He will have everything you will need to get that clutch fixed right.

Do it right and do it once.
