Tc 33d PTO won't engage after chain fell off snowblower

[SUPERSTEER]

The main drive chain fell off the sprocket of my front mount 60" snowblower., Now The mid or rear pto will not run,I checked switches, levers and linkage move freely, SHEAR PIN for both pto's??? In rear end ??? HELP!! Tractor still moves [ hydro] Front hydraulics still work, Any help would be appreciated!!

WOW, No ideas, Nobody has had any PTO issues? I think the splined coupler let go on the main shaft feeding both pto's. HELLO, Anyone out there?

you need to be more specific in your description of the problem.

so lets troubleshoot the rear as you can actually see it....

your in HST2 range... and moveing forward
you push the clutch in while still keeping the HST peddal pressed.
the tractor stops moving forward...
You can feel the pto lever firmly engage...
You see the orange dash light come on indicating PTO in operation
you let the clutch back out the tractor starts moving forward again
you look back and see no rear PTO spinning?

Correct, Everything works as normal, Clutch is working. Both mid and rear PTO'S engage, shaft going into trans moves freely clicks in , light is lit and neither run. Tractor is in heated 55 degree garage. here is what happened, I touched off the blower on an icy snowbank , The main drive chain came off, Which takes a lot of force to come off the sprockets. I took off masterlink and realligned sprockets , Put all back togather and now neither mid or rear pto's work.........From a schematic I found I'm thinking the splined coupler on the main shaft that feeds both PTO'S...... Has anyone had any of these probs?. HELP!!!!!

You may as well drain the oil and remove the hitch cover so you can see what is(n't) going on. it's all speculation till you do that.
The sprag, or one way clutch may have grenaded.

Rickb, Are you at capital tractor ? Thanks for some input. Would you have access to service manuals? I'd be willing to buy a trans section. Any other help would be greatly appreciated..Thanks

No, I am in Pine Plains. You can go here and buy NH manuals direct without the dealer's markup:

There are two sets of manuals for a TC33D. The later set lists a serial number range. If you are prior to that range, or don't have a 'G' prefix s/n, you need the set that also lists 1530, 1630, 1725 and 1925. That complete manual on CD in pdf format is under $90. They are apparently getting out of the business of selling individual sections, as only two are available, neither for transmissions.
