The pedal kind of mushes to the floorboard without releasing, but pretty much everything is hidden inside the bellhousing, the tractor has to be split to see inside. May as well do it!
First support the front half on blocks, the rear on a trolley jack. Battery out and remove seven bell housing bolts.
Tip up and prop up the hood, remove one end of the radius rods and tie rods.
Remove the exhaust pipe clamp, coil wire, throttle and governor rods, hour meter cable and an oil line.
Pry the two halves apart about 6-8 inches and a look inside shows the throwout bearing is OK. The clutch comes off the flywheel with six bolts and- about after about an hour of working inefficiently...there's the problem- the rivets have sheared on the disc and the plate comes out in bits. If it is original, it's lasted 68 years.
One of the nice things about this model tractor is that most parts are still available, and a new plate has been ordered.
