I have a factory grader blade on my 425 but have not had much of a chance to use it.Your's looks like it is going to turn out pretty good.I always had intentions of building one for years and a new one  just fell into my lap.I didn't even realize they made them for my machine.I think it was actually made for the newer X series.

 

Mine mounts from the rear and does not have down pressure.

 

Is it better to have it mount from the rear if you have no down pressure?

 

My thinking is that it will exert more pressure as it tries to cut in while mounting it on the front might have the opposite effect?

Yes, it does cut more, just like a front mounted dozer plow hence the use of the adjustable feet. Dragging the blade is much more flexible in what can be done to the blade due to the draft and suction created by the blade in pulling.

 

An esample is all moldboard plows are drawn, not pushed, same with vators or any other plough, ever wonder why motor graders drag the blade.

 

A idea you could add to control the suction created by the cutting edge would be to use a trip snow plow, remove the springs and weld on two pivots for bolts or the like hinged to the middle of the plow to the plow carry frame, the bolts (or what ever adjusts and is strong enough) can screw in which would tilt the moldboard forwards reducing the suction on the cutting edge, driveway graders use a near vertical to flat blade, in reverse the cutting edge is extream and cuts more like a plough, this is a common mistake people make with graders and make up for by using weights on the blade when the suction is not enough, more or less they are dragging the cutting edge across the ground and vice versa when scraping.

 

If the grader is to be used just for general driveways or spreading around material a fixed blade would be fine. If the blade is on a hinge to tilt back and forwards you can control the blade without fighting with it, with the side to side tilt and plow points added to the edges of the cutter blade. If so tilt the top of the blade all the way back, turn the blade all the way to the front and angle the tip into the ground like a plough, you can cut ditches with it.

 

Side suction and draft is not too much an issue seeing as the tractor is a solid platform on four  wheels, it gets tricky when used as a walk behind.

To show you what i mean by replacing springs and the pivot point on a trip plow, below is a picture of one showing the springs, replace the springs with long bolts or the likes.

I do have down pressure on the lift. The float is in the lift valve!

I haven't a clue what the difference would be on how it's mounted! Have you got pics of yours? I can use all the help I can find for this!

I just got done using it to clean the top layer of silt from my drive.

It only takes 2 seconds to angle from side to side.

 

I am sure KennyP will have hydro on his!

Yes, it will go on a hydro tractor, but probably not hydraulic actuated.

Well new issues showed their ugly head! I started mocking up the lift mechanism for this and had not taken into account all the steering apparatus under there. Right in the way. So more thinking is in order.

Kenny, when you get a chance to, could you stage the blade with push frame under the tractor and point out the steering arm issue, flash a pile of photos from the front, side, back and the push itself, no shame, lol, , point and shoot, the more the better.

 

Could you also outline some of the metal stock you currently have to work with.

 

Im really starting to pick up speed up here so my postings will become increasingly sporadic.

I'll see what I can do. May take a couple days as I am working the yard rake right now. Need it done soon.
