[1965-100]

Greetings, it's been years since I was on last asking a question so I guess that means well for an old Cub Cadet.

I am using my son-in-law's grandfathers 1965-100 and it's been great. But today at my first mowing of the year it refuses to move when letting the clutch out. It worked fine for 10 minutes.

When I let the clutch out it seems like it want's to move just a little when the clutch is halfway out but then just stops and I had to push it up driveway with engine running and in gear.

When in gear and engine off I can push it easily in any gear.

I welcome any wise counsel and advice on what to look for and the difficulties to get this fine ol mower going again.
Thanks
Gary
