Are many still using them?
I have 5 of them, some from tractors that are sold, I have never used any of them ever.

Is this one off a Deutz?

Used to use the 21 spline for harvester long go but got sick of changing the stub so desided to change the yoke on shaft to 6 spline. Anything 1000 speed is six spline now.

My neighbour is the only one I know of who still has 21 spline shafts on new implements! I think he hasn't realised that the lever in the cab changes the speed of the shaft without changing the stub!

He has 3 machines less than 7 years old, all with 21 spline shafts! He has 20 and 30 series deeres!

We used them on silage harvesters down through the years and had one on the first power harrow. I was using a friends Claas mower Monday and I had to swop shafts, it was a 21 and not very old, possibly 10 years.

I worked on a place for a summer and they had 21 spline shafts on anything running on 1000, I had to change over 3 or 4 times a week, sometimes twice a day. I have never used the 21 spline outside of that

A fair pile of them here right back to 500 series , once shiftable ptos appeared all the 1000 ends were changed , the minute they land in the scrap is when someone will be looking for one.

The Taarup double chop had a 21 shaft, back in the mid 90's.
Also a large Dowdeswell rotavator, gone with the beet.
So l have stubshafts knocking about somewhere in the shed, havent seen them in years though.
