Been busy on this 3 point!  I got to thinking it would be good to keep the original JB look to the rear if I could.  So I drug out the old rear section that I had to cut out to get this new driveline installed.  So instead of a LOT of fabricating, I have redone the old rear plate so that it will bolt on for easy removal if needed.  I had to cut out a pieece to weld onto the old plate, as the rest had to stay with the chassis.  I have large angle iron welded at the bottom that will bolt to the heavy angle that the transaxle mounts to.  Then I welded smaller angle to the rear plate at the sides which will bolt to the side panels once I get all the holes drilled.  The rear plate will be 3" further rearward, so all I need to do is build cylinder mounts 3" longer than stock to hold the OE Bush Hog lift cylinder.

MUCH easier doing it this way, and I hope to add rear pto some day, and being removable is a big plus when/if the pto idea becomes reality.

Just remember it's 3" further back when you go to lifting heavy things. The front will get lighter sooner.

Glad to see you are able to bring her back to looking like a JB in the back again. I think it looks great Daniel, and that ability to access the axle and PTO is worth a lot of time  for you. :thumbs:

Doubt that will be a problem with that diesel engine in the front.

Well, the rear axle center point is almost 2" further rearward than the original JB axles, so in reality, the hitch is only 1" further rearward speaking in terms of leverage.

So the front end has an extra 2 inches of leverage!

Just got the mounting holes all drilled, and the plate is mounted!  With any luck, in between milking chores tomorrow, I can get the cylinder mounts in, cylinder hooked up, and she'll be ready to plow again.  She ain't pretty, but maybe I can make it to a plow day near me this spring!  :dancingbanana:

If you stretched it an extra 2" and only moved the plate back 1" you actually gained lift capacity because you increased the leverage ratio greater than the hitches distance from the rear pivot point (axle center line).

Just finished installing all the 3pt lift components.   :dancingbanana: Only thing left to do to the 3pt is the cylinder needs a new shaft seal soon, or new cylinder, as the shaft has some pitting.

 The entire tractor project is beginning to wind down.  Most of the mechanical/fabrication is done.  Just need to brace up the brake pedal mount area, make a small metal shield, and a few little things.   I would like to say paint will be sometime this year, but available time will control that outcome.  I can do mechanical stuff in series of short bursts, but readying it for paint will take a LOT of time, and while prepping, not being able to use it plays a big part.

Forgot a major thing I need to complete on this tractor.  The front axle beam needs to be widened 3" to give clearance for the left tire when it rides high over an obstacle in a tight right turn.  So far I've just avoided such turns, but I want to get this corrected.  One afternoon should do it, so not terribly hard to get done.  I can still use it just as it is with caution.  When I widen the axle, I will also raise the front end of the tractor about 1 1/2".

Whoops!  Had just a few minutes before milking the cows, so I thought I'd drop the front end out from under the JB so I could get right to the widening of it later.  But Houston....we have a problem!  In my haste to put the diesel engine into it, I did not swap ends on the center pin of the axle beam.....yep, the head of the bolt is next to the oil pan!  :wallbanging:   I "may" be able to use a .045 cutoff wheel, or maybe even the plasma cutter can get in there, but not simple as I figured.  I would just leave it as-is & widen the beam while still on the tractor, but the pivot bushing is worn bad & needs replaced.  Oh well, my fault....my job!  :(

I can understand how that happened. Been there, done that! All the careful planning and heavy thinking just got blowed out the window! I know you ain't pulling the engine!
