Was the short engagement lever for the pto discontinued at a certain serial number or year?  A friend of mine is looking at a late '66 model with that lever, and I was under the assumption that was on the '64 or early '65 models, but I could of course be wrong about that.  Was it an option all through production, or stopped when the series 3 came out?

Manual or hydraulic engagement?
 Short rod out of the floor was mechanical, or a short lever on side of counsel control tower was hyd. and little while later they put the long lever in on the left side for the mechanical.

It's the short mechanical engagement lever by your heel, this tractor has just a hole for the engagement lever in the console.

I should've clarified that a little better, sorry.  I'm just curious if the rear end has been changed because of the short lever, and I forgot to check the axle size and for the hash marks on the axle housings while I was there.  I know what you mean by the long mechanical engagement and short hydraulic engagement levers.  Can the long lever be put on in place of the short lever without much trouble, since it's quite a pita to deal with the short one?

The long lever style on the left side of the seat occurred at s/n 14,186 and up. BUT, there are hundreds of older tractors that had these parts added on over the years. The external/internal old lever would have to be modified to work with the long lever left of the seat. Technically, the tractor would have to be split to change that lever, but I'd have little problem refabbing it in chassis. Changing of a rear end would have ZERO to do with the improvement, other than this external/internal shift lever swap would have been easy to do at that time.
