Out of curiosity does anyone have a complete pto shaft assembly for this tiller in good usable shape?
Thought I'd try this route before I order the parts to build one.......thanks

Yup, I sure did.......just short the pto shaft half that goes on tractor and both safety shields.
Kinda scared to use it now tho......gearbox parts are nonexistent and been told it's easy to strip the gears out inside box!
Thought about setting the slip clutch fairly loose that way it gives before it takes gears out......what's your experience!?

Hmmmmm,well I do some custom tilling for some extra cash. I did this one last spring.it was an old in ground pool that he neglected to mention.by the time I got it shut off,ut had a bunch of times bend to rat sh*t and both bearings buggered. No issues with the gear box at all. I have not tillers.the 48 tiller I actually snapped the output shaft off years ago

I run my slip clutch loose enough to slip before doing damage, but after sitting a long time, the discs can rust weld themselves tight, so I loosen my clutch a lot to let it slip to smooth things up, then tighten back a bit.

Thanks for the tip Daniel....hope all is well your way!
Yup I know exactly what you mean by the friction disks rusting together......our batwing mowers have a tendency of sticking after sitting over winter. A quick loosening of the bolts and letting them spin alittle then retightening does the trick.......👍👍👍
I never looked on agcopartsbooks or contacted my local dealers but maybe you know.......are the friction disks still available from agco/MF or any other aftermarket source?
I tried locating gearbox parts thru agco and had dealer check other dealers inventory......also checked depotparts thru dealer.......the shafts and gears are all gone.......thought about checking with my local machine shop guy about making new gears and shafts.......makes a guy wonder how many these tillers got junked because of no parts availability!?
Sorry for rambling on!

If anybody has been looking to build 2000rpm drive shafts this place has a lot of the materials to build what u need.......I have yet to do business w them so know nothing about them......just stumbled across their site and thought I'd pass the info along......hard to find 2000rpm driveshaft materials!

Hang onto your seat when you go to make that shaft from scratch as you will have close to $200 in parts buying from Ricks I sent them an email on the parts and they are not cheap but as my brother always says Well try making it work without it

Hey nick......how you been!?
Yeah I priced the stuff needed to build that shaft......haven't pulled the trigger yet but looking like it's coming down to that since can't find anything used.
Not crazy bout spending the big bucks for all new but what ya gonna do........pretty tough to use it without a shaft! Lol

Do not forget Weasler.  They have #6 driveshaft components.  Our best bet would be you local implement dealer.  I have used them with great results.  Fleet Farm also handles Weasler but do not have the 1 x 15 splined yoke or shaft.

 

Also the OEM drive shafts are repair with a little work.  I have some info on that if interested.

Could someone give me an overall length for the driveshaft on my 4850 tiller.
From tip of input yoke(part going into tractor pto)to the end of the square shaft that slips into the square tube shaft part.
Also how long is your shield on front part of shaft?
Pictures would help too if available
Thanks!
