Some of you folks may remember this thread. I finally got some time yesterday to work on this some more. One issue holding up progress was figuring out the lift for it under the FF/20. I think I have that figured out now. So I plan to do more to get this thing working.

Here's a couple pics of yesterday's work.

This lets me see what clearance I have to the underside of the frame. And how tall I can make this blade. Not nearly what I had hoped for. I may have to cut the blade down to 6" tall. Still noodling some different options, but going forward with this.

As things are right now, the blade stands 8" tall. The 'swing' mechanism is another 2.5" tall. That's just about what I have from the ground up to the lift when it's raised. Not good! I may be able to gain another 1/2" to 3/4" under there, but still not enough as I would like at least 2" ground clearance with it raised. So the blade will have to have 2" cut off it. That will take a bit as I don't not have a torch!

Sounds interesting Kenny. I am still kicking around the idea of building one. One thing for sure, this site gives me a lot of ideas for what all I want to do.

Kenny, can you notch the top of the blade to fit around the lift arms? Looks like it would gain you an inch or so. Cut the blade down with cut off wheels, it will take some time, but will be a clean cut.

The issue there is if I 'tilt' it, it'll be against one foot board or the other! Think I have it figured out, but still much head scratching going on!

OK, I hadn't thought about tilting it but that would be a worth while option.

It will have tilt, Brian. Maybe only a max of 5°, but that can be a big help. I'm working on that now. I got a little more done yesterday.

Here's the front cross piece. It's 5/16" X 3" X 4". The tilt will be on this.

Here is where I moved the lift links holes closer together by 1". This gained a lot of height I needed.

Image020.jpg

 

Here is my redneck mill at work making the hole for the support tube to fit.

Hole saw was a little big, but it'll work.

This wasn't much progress, but I was thinking about the tilt mechanism. May have it figured out. If so things will move fairly quickly.

Just for info purposes, 5° across the 5' blade equals one side being 5.2" higher than the other. That's a lot of tilt.

I got a bunch done today! I started out on the tilt, Found a fitting from a dead LT that looked good. 1/2" hole, but no threads. Welded a nut to it.

Image024.jpg     Image025.jpg

 

Next I test fit the carrier tube into the 3X4 angle.

Image026.jpg

 

I needed to trim the radius on the swing. Nothing to draw the arc, so I made do with a stir stick. Then it was cutting on that radius with the angle grinder. That's fun!

Image027.jpg     Image028.jpg

Image029.jpg

 

Next was fitting the tilt bar into the inside tube.

Image030.jpg     Image031.jpg

 

This tube is a little thin in the wall dept, so I am adding a vertical bar inside and will weld thru the 1/2" holes I drilled. This bar is also welded to the tilt bar before installation.

Image032.jpg     Image033.jpg

Image034.jpg

 

Fitting parts back for finish weld.

Image035.jpg     Image036.jpg

 

All together! Just need a tab on the angle for the tilt bolt.

Looking good !   Will you be able to tilt the blade from the drivers seat ? Like those old road graders . That would be very handy , the rear blade I made and pull with the PK is kind of pain because every time I turn the blade from left to right I have to adjust the lift arms to either keep it level or when I'm trying to crown the driveway .

Al, I'll have to get off to adjust the angle. It's located down near the right front. Gotta figure out how to fix the turning issue first. Cannot move the mount back to clear as there is the lift cylinder and fitting right behind it. I'll look at it more today and see if trimming will work. Kinda bummed me out yesterday!

 

Edit: I rotated that last pic for a better view.
