We purchased a used White 6B 598 vari-width plow last week. I have milked about all the life out of the old early 70's Case hydraulic reset plow. The White plow had dealer stickers on it from a dealer in Indiana. Likely it never had to turn furrows on sidehills. Several Mfgs mounted a cylinder down on the hitch bar to shift the plow RH and LH in relation to the tractor, but they did nothing to actually steer the plow RH to LH like the landing lever on a 3pt mounted plow. The brackets that I fabricated actually steers the plow by changing the angle between the draft beam and the plow beam. The old Case plow had the same setup. The plow beam and the draft beam both had some 5/8" threaded holes already where I needed them and I drilled and tapped a few more for the main bracket so it will stay secure on the draft beam.
In making this attachment, it is also necessary to release the clamp bolts that tie the draft beam to the front cross frame. Easy to do. Just cut 4 pieces of 3/4" pipe and place them between the clamp assy. so the draft beam can slide laterally on the cross frame. I just smear some grease on the cross bar so clamp assy slides on it easily.
The long pipes that connect to the tailwheel will get cut and rethreaded at the pivot point and hoses will be strung up to the tractor to operate the tailwheel. I also had to raise the mechanical indexing gauge that shows what setting the bottoms are rotated to, and modify the linkage just a bit so nothing gets pinched or bent when the cylinder strokes each way and the bottoms are rotated.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
