1952 8N with a Sherman... caught between gears???

Any ideas or help? Plus I would like to get the repair manuals for this thing and the sherman, any good connections for that?

Bad News: Missing a tooth with some others chewed up.

Yer trannys been jambed into 2-gears at the same time. That is why it is locked-up. And that is why yer engine dies when you let the clutch out. And that is why yer PTO driven brush-hog has a push-button disconned coupler so you can hydraulicly raise the brush-hog without the blades whirling. Remember, yer hydraulic lift pump is also run by the same PTO gears that drive the brushhogg blades.

As fer yer current delima. Remove yer 8n's tranny shifter top-cover (watch out for spring loaded detent balls going sprong) Remove yer gear shifting forks and inspect yer gears to find out which 2-sliding main gears are on the same gear of the counter-gearshaft. (tip: iff'n he was reversing off the trailer, probably reverse and 1st gear) Note also, the PTO shaft is also coupled to the tranny counter-gearshaft with the behind yer leftheel PTO shifter lever.

Recommend you consider the merits of buying your very own copy of the I&T FO-4 manual. $27 (cheap)..... ...respectfully, Dell

I am definitely going to buy my own manual.

But before I tear everything down I was hoping someone knew by the sound of it what it was. I have the shifter cover off and the gears toward the back of the tractor are the ones that seem to be frozen up.
