800 pto won't engage

I was bush hogging the field and the pto kicked off like it does on occasion.It will not allow me to put the lever back to engage now.Pushed clutch in ,have drove around abit,shut tractor off and rolled it,turned mower pto shaft,etc.Will not allow the lever to go rearward.How shall I start to determine what broke ? Do I take half the differential off,do I need to split the tractor ? Any help is appreciated since I need to finish getting the food plots in.Tractor is in nice shape. Thanks in advance Ed M
 
well.. it's been crying for help for a while now and you've been ignoring it.. why now are you concerned with fixing it???

it poping out of gear was a SIGN. it either had a bad pto bearing, a loose detent ( not likely ).. or most likely a damaged split ring or bearing carrier. you will need to pull the shaft and the pto shifter cover possibly, to find out more.

remember the pto shaft passes thru the hyds sump.. so you must drain the hyds and diffy before pulling the shaft.

what happens is the shaft can move in and out and walk out of engagement, damaging the splines on the end of the shaft and the sliding coupler.. it can also mushroom the end of the shaft. when one or both of these happens.. well.. she becomes hard to or won't engage.

I appreciate the reply.I thought maybe when I would hit the really tall stuff it would pop out because it did not have the 2 stage clutch like my MF 65.It would only pop out at most once every couple of hrs of use.It never popped out with the pto rototiller,just the bush hog. Thanks again. Ed
 
clutch style ( single/dual/independent ) has no operational bearing on the pto. it is a hard engagement and should not slip out. when it walked out enough to come out of gear.. that is where/when the damage occurs. as alan said.. implement deosn't matter.
