Grinding Gears

Had a 86 model JD 850 in here last week that was grinding bad whenever you put it in gear. I split it to replace the clutch and throw out bearing. The main disc was in 2 pieces, the lining had came loose from the rivets, the pilot bearing was gone except for the outer ring and the pressure plate had some broke springs. I didn't take the plate apart but just looking at it the pto disc looked good. The flywheel was flat with no burn spots, I put a new pilot bearing, disc, pressure plate and throw-out bearing in it and then back together. It still grinds going into any gear whenever you start off from neutral. I've got about a inch of free play in the pedal, when releasing the clutch it will first engage the pto then the transmission, works like its supposed to. Don't understand the reason for all the grinding.
 
There has to be someone out there that could give me a few pointers on this. I was wondering if these transmissions had synchronizers like the older truck transmissions and they were broke.
 

Assuming you are giving it time to let the shafts stop..have you tried to activate your Hydraulics, to stop the clutch from spinning..(or is the Hydraulics driven another way)..?

A full inch of free-play is surely plenty...

Thanks for the answer but don't understand how the hydraulics will stop it from spinning. The pump is mounted up front, just nothing that I can think of that would stop the trans. from spinning. I have a manual but was unable to tell if this trans. has synchronizers.
