I had mowed (bush hogged) a pasture for an hour, depressed the clutch, put PTO in Off and tractor in 8th (Hi) gear then drove down the pavement for ten minutes to the next field. As I decelerated turning in the temp light came on so I drove straight to the spicket 150' away. Raised hood ran water over the radiator (95 degrees that day) and the light went out very soon. Got back on the tractor and could not get it in gear (grinding as if no clutch), but the PTO would shift into gear when I depressed
Let her set overnite and problem still there. Remembered the "Freeing up rusted/stuck clutch" trick of pulling up to a tree, but the back wheels just dig down. Had the tractor for about a year (made 78-88) so clutch may have just went out, but it never even slipped before this. Any ideas would be welcomed? It's a two stage clutch. Had to crank it in gear to get it back home.
