Hydraulic Angle Rear Blade

[liledoun]

Check my approach on a low cost blade. It works great with no problems over the past couple years. Pictures are posted at: Pictures Several other public picture albums are available at that site.

The T'N'T really helps the blade useage. My design is easily removeable for reversing or puting it on the landscape rake.

I posted a full description of the parts, etc in a post a year or so ago.

Good luck,

JR

Hey JR I didn't see any pictures of the blade reversed. Can you be so kind as to post a picture of either the blade or the rake reversed? I would like to see the hydraulics in that position as well. Thanks!

The angle cylinder does not work when the blade is reversed. It must be released from the blade before the blade is reversed and the lock pin inserted.

In case you didn't realize it, PineRidge was just giving you a hard time........ he likes to cause a stir whenever possible. You ought to meet the daughter..... just like her father... always causing a disturbance in the family over some nonsensical issue /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif..

Ok..I'll take a guess...

You must be the daughter! /forums/images/graemlins/shocked.gif /forums/images/graemlins/shocked.gif /forums/images/graemlins/shocked.gif

It's all starting to make sense now... /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

Hey Junk looks to me like Henro has you all figured out.

Looks great and appears to be a pretty straight forward mod. This is something thats been on my list to do for while.

I'm assuming you can still spin it around if you wanted to and pin it.

Can someone tell what a cushion valve is? Is this something that would be on the cylinder like a check/pilot valve?

CT,
You can spin it 180 degrees by removing the cylinder pins. With another front cylinder mount on the opposite side, you could rehook the cylinder and use it in the reverse angle mode. I plan to add that this summer.

CT,
The cushion valve or a cross over relief valve protects the components by letting fluid go from on end of the cylinder to the other at a preset level with out passing through your regular service valve.
Example, No cushion valve in system. You have a grader blade on the three point hitch and catch the left end on a tree stump. One of several things can now happen. Engine stalls, tires spin, stump breaks, blade or hitch parts break or bend, hydraulic lines blow because the pressure that has built up as the blade pushes against the cylinder is more than they are rated for.
With cushion valve blade hits stump, pressure rises in the cylinder and line against the valve relief setting. When the setting is reached it opens and allows the oil to cross over into the other end of the cylinder until the pressure is below the setting. This will result in a movement of the cylinder, but protects the components from excessive damage.
Most snow plow angle circuits use one of these.
Both the A and B hoses on the service valve connect to two ports on the cushion valve. Both cylinder hoses connect to two ports on the cushion valve, basically it forms a "H" between the two hoses with the cross bar "-" being two relief valves that let fluid flow into the other hose.
