Gerg 14 Posted March 7, 2018 Finished building my mid-mount blade, tested on both 7117 Simplicity and 446 Case. Its was designed for the Simplicity and adapted to the Case. It pivots 0 to 25 degrees up and down both ways and 25 degrees front to back both ways. Work good on both tractors. Greg 5 Share this post Link to post Share on other sites
spi 416 Posted March 7, 2018 Good fabrication, looks like it is heavy enough to get the job done. How about some closer pics. of the adjustment details please. Thanks Jim 1 Share this post Link to post Share on other sites
Gerg 14 Posted March 8, 2018 I will take some close up photos and post them. Greg 1 Share this post Link to post Share on other sites

720nut 3,789 Posted March 8, 2018 Welcome I have a simple question as most blades are solid mount with angle pin, why the pivot ? just curious. Nice job 1 Share this post Link to post Share on other sites
Gerg 14 Posted March 8, 2018 Attached are some close up photos. The answer to the question "why a pivot" There are 4 reasons: 1 - To adjust out imperfections such as twist in the mounting frame and tractor height differences. If I am running a fixed level blade then I park it on level concrete and adjust so the blade is even all the way across. 2- One of the advantages of Simplicity and AC tractors is that the mounting for the attachments moves with the pivoting front axle which is good in most cases but not so much with a blade. By taking the stop bolts out completely letting the blade full float eliminates blade lift when one of the front tires rides over a hump. I have used it in limited float ant it works great. 3 - The blade when pivoted at an angle works good for tapering the edge of the driveway. 4 - I am going to build a dirt go kart track with banked corners, with the blade fixed at an angle it will continually build up dirt around the corners increasing the bank height. (probably easier said than done) 1 Share this post Link to post Share on other sites

PhanDad 3,245 Posted March 9, 2018 Great work. A lot of thought went into that design. You'll have to share pics of the go kart track when you complete it. 1 Share this post Link to post Share on other sites

Gerg 14 Posted March 23, 2018 Thanks to all of the replies. I am in the process of building a tooth bar attachment for the blade to loosen up hard packed gravel ( if it ever gets hard, frost moister is still coming up). Greg 1 Share this post Link to post Share on other sites
Chuck Mallory 917 3 Posted June 8, 2018 (edited) Thanks for the close ups. I just started building one for my 1985 917 Hydro. I found an old drag in my woods and plan on using that to make a raker tooth section that will flop down from a locked position to break things up before grading.

Manty 21 Posted June 11, 2018 Hey Greg - really like the center pivot on the grader blade. It would really help in putting a crown on a driveway. I would also like to see the toothed bar attachment when you get it - I've been thinking of making a ripper attachment to my stock blade to loosen up the driveway. It would be great to have an attachment that would go on & off easily when needed... a update to the much loved 'Dutch Blade' 1 Share this post Link to post Share on other sites
