Default Cub Cadet 1872 SG Tractor - Oil and PTO Clutch Woes
Hi all,

Today when I went to mow the lawn, the blades quit moving. I pulled it over to the driveway thinking the grass had clogged up or I spent a belt. She was leaking oil pretty bad on the driveway. I made sure there was oil in the engine to prevent engine damage.

I pulled the front end apart and it appears the oil seal on the PTO shaft is leaking. I can't find the part in the parts tree online - anyone know where to locate it?

I tried to reengage the pto and the blades spun, but not as well as they used to. I am thinking I may have gotten oil on the clutch friction plates? I did notice that the plates did look a little worn - I can see ridges in them. Do I need to replace them? I don't think the clutch has been adjusted....ever. My dad didn't take too much time to maintain this machine. However, I want to make it right.

PS how does the PTO clutch work? I figured there would have been some friction material in there similar to a motor cycle or car clutch. I just see two little ridges. Does the driven side move towards the engine when the coil is energized???

Thank you!

Download the shop manual from our tech section.
Bearing IIRR is a 6206 commonly avail most any parts stores/ebay
Clean the clutch up with your favorite parts cleaner reassemble with new bearing and set air gap to .010
no lining in the clutch, steel to steel.

The number George gave is correct, to find it on partstree look under crankcase, then rear seal, as the front of the tractor is the rear of the engine.

Thanks for the help guys! Steel on steel, who da thunk it.

So would I be correct to assume the metal tangs holding the driven plate to the sheave flexes ever so slightly to engage? Otherwise I don't see what slides/moves. Must be one powerful magnet!

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.
