Offset Rear Blades --- Swinging vs Sliding

I'm in the process of rebuilding a very old eroded roadbed. So I need a rear blade that will recut the drainage ditches and then blade the fill and gravel surface; and eventually maintain the road.

I'm looking at the two different types of rear offset blades, not box blades. One is made by Leinbach (Model SO-6)and offsets using a 4"X4" swinging beam; the other unit is made by Midwest (Model RB22-72)and has a moldboard backing bar that allows 24" of horizontal offset. Both have the tilt and angle features for grading and working ditches. The Leinbach is a heavier unit (393 lbs) than the Midwest/Corriher/Kioti unit (304 lbs). From a geometric standpoint it would appear that the swinging blade would be able to cut a steeper ditch than the sliding setup.

Are there any advantages or disadvantages of one system over the other? Anyone have any experience with these blades? Thanks in advance for you thoughts and advise.

Lou, my first comment, based on a LOT of years of maintaining dirt roads is that yoiu are going to need EVERY single hp and pound of weight that poor old Harvester can make.

Cutting into the ground takes a lot of grunt, when it's off-side even more so since it's easier to swing the front-end around than to cut the banks by much. Add as much ballast as you can possibly manage since you won't have the added traction of the front wheels pulling.

Past that I have always had better luck with the swing-beam style, the leverage produced when you meet a rock in a ditch bank will quick put a bow in any blade stuck out beyond the frame by much.

If you can find a rotary ditcher the work will go WAY faster, then you just follow up with the blade and massage it into place after the ditches have been dug.

Best of luck. ....
