questions re. the pto on my howard rotorvator
the shaft is too long , I have to run it with a very long top link so I doesn't bottom out , don't think this is a good plan.
it does about 45 mins work a year for me on me veg. plot . ( prob 20 yard / meter square )
if I worked it for hours it would probably fail some were but it doing my job.
the shaft is splined , many splines prob 20 + , I thought all ptos pulled apart and then you can chop a lump of to shorten , my local agri. dealer agrees . this one is captive together , it telescopes but wont separate , ??
I cant decide if there is a collar to unscrew .
I was going to buy a new guarded shaft but his books didn't have one. vapormatic books. I have not researched online yet
the gearbox end has a spline and a parallel boss which sits in a oil seal , retained with a roll pin , not just a standard spine .
is advise is to keep the gear box end yoke , fit that to a new shaft which he cant source ! good plan if I can get one ?

if I can shorted it by about 1" , 2 " would be better then it will prob live for now

I bought the rotorvator about 10 year ago out of the village scrap mans skip for £25 !! it is not pretty but it does a good job and better than a spade / digging fork !
post photo soon

gear box end , prob standard 6 spline shaft , the shoulder for the seal is the odd bit .

the spline , the tine bit does unscrew , very fine thread but that didn't help ,

hi i would have thought it would come apart however thou its hard to tell from the photo a diffrent arproch may be to lower or make an extenton on the lower pins to move the hoe further back may only need an inch or so b

I'd wondered about modifying the lower link pins , 1 " further forwards , towards the tractor would prob do it / push the rotorvator further away from the tractor.
so yes you're right that might be the answer

it starts to get close with implement lowered deep into work , if its held up shallow with the position control all is well , I run it set at full depth 1st. gear 1800 revs ish on my mf 65
tried it this spring on my super dexta , same prob with the pto , noticeably make the dexta bark but it does it .

I used to use it full throttle on the 65 1st. full depth but it digs holes less of a problem at 1800 ish , because of the little square plot and layout its always a draw forward and back
up , which doesn't help , the soils always thrown backwards .

If the shaft has been a bit too long and has been compressed too much could the internal part have mushroomed out on the end and thats what stops it telescoping apart?

Possible
I'll have a look

bin to two agri dealers now , no one can separate it , 'never had one that didn't come apart before !'
even if it did separate I believe the female spline is only in the last few inch's , so it would mean cutting out a lump of the tube and rewelding it straight ,
im gonna mod the lower link mountings ,on the implement
if it looks presentable i'll post photos
thanks for help.
