Plow blade modified to fit snowblower mount (early design)
Posted September 03, 2015 - 06:31 PM
Now I happen to have a spare snowblower mount which goes between the blower and the mount bracket. This has been the inspiration to this modification. This will be unique to my set up partly because I am running a modified Craftsman blade to start with. However, this can be adapted to work with many blade designs and even full custom fabrication of a mount between the blower frame mount and a plow blade.
Tonight I brought up my spare 42" blade which shares the exact design and interchanges with my 48" Craftsman blade. I am planning to use the 42" blade to keep the stress down. I am also planning to design some push arms that mount between the frame and the bottom of the snowblower bracket. I do not know yet where these will go, or if I can even do it with the axle clearance. More on that later. I may also work in beefing up the frame bracket. Where it mounts near the grille.
To get started, a few photos!

It appears my main hurdle is the lift arm is in the way of where the adjustment notches are. However, I am sure I can work around this. I may even be required to move the point that the arm mounts do get the best lift out of the plow blade. I am not worried about float for upwards movement as the lift rod is two halves and slides to allow it to be pushed up, however, I need to maximize upwards travel and some sort of drop for the blade too. But for the most part, it looks really good!
This will be a little more light duty than the rear mounted plow but I am going to try, and you all get to watch and see if it works!
I have attached a photo of the mower deck mounted up with the blower frame mount in place. To do this all that was needed was to cut off the plate between the arms and move it behind the mount, and flip it upside down.

I was surprised that the blade mount gives the blade set up the appearance that the blade is very high at the mount! I was sure it would be pointing uphill because the frame bracket is so low.
Now that I have an idea how it will sit, it's time to try to midify what I have into a new mount. Once that is done, I can see where it sits and if the lift arm mount needs to be repositioned.

Looks good so far. Hope it turns out the way you want it.

I need to pick up some 1/4" strap to brace it up, and tack weld the set up. The other nice thing is by cutting the welds on the frame, now I can pivot and place the mount where the length works the best for me to lift the plow.

Ok, I know it's been a while... but let's be honest, no snow yet!!
So today I attacked my mount bracket with the mig-welder and grinder. First I had to drop the mower and mock up the mount with the blade and lift rod attached. This was needed to make sure that I rewelded the rod for the lift arm in the best rotation for lift and drop. I want the lift arm to be exactly the same for the plow and snowblower.
With the blade on flat ground, I set the handle in the middle position and tack welded it in place. This gave me a nice lift height and plenty of drop to keep the blade on the ground as I pull out of my garage. (My driveway has a pretty good slope right out the garage door, so this is important)
Using the stock lift, and stock snow blower lift arm, works great and has a perfect "weight" without using a helper spring. The only one thing that I am unhappy with is that there is no "twist" in the mount bracket. Because the bracket does not twist, it will not sit flat when angled. I may be able to elongate the mount at the snowblower frame, but that gives me less than a 1/4" before it will pop out of the mount. My other thought would be to use a "floating" cutting edge. Allowing it to float with a center pivot and 1" travel on each side. However, I think that it would pack with snow and not work right. I could weld up the slots that lock the angle tab and recut the slots with less travel. That would limit how far it can angle to help it out how much the blade needs to twist. I did manage to get it flat with maybe 50% less pivot, but If anyone has an idea, toss it in here! I know that a lot of tractors use a mount pivoted off the front of the frame like this, but I am not sure how they deal with the float when the blade is pivoted left or right.
I will also drill some holes in the snowblower frame mount at the lower rear corner and then add braces up to the mower hanger brackets. That will help with stress from the plow, yet be removable when the blade or blower is off.
The other modification will be to add a "U" shaped end to the lift rod. This will allow a pin mount to the bracket, allowing me to easily switch between the plow and snowblower. Three pins, and the plow slips right off the tractor, and the blower goes right back on.

Well it looks good, lots of work and thought has gone into it. Be interesting to see how it holds up, you got 1000lbs + behind pushing that.
One thing that might work ??? to get the frame more level to the ground so the corners don't raise up when you angle the blade would be to put a tall, 4" or more wear bare on the bottom of the blade. That way the blade doesn't go down as far and the frame (horizontal) stays more level to the ground, if you get what I mean.

Good tip, that may help a lot! Oh... and weighted down, I think she's porked up to close to 1250!

That's a great looking 12G and fabrication work! Thanks for the detailed build and pics.

Looks real good. I just picked a blade for a Gravely that is real similar where the blade mounts to the frame work. Was thinking on how I could mount it on my 718H Modified AC. Might use something similar to what you have.

Some of the sears blades have this issue too. I've looked at them and decided to leave well enough alone. One thing would beget another, and another, and another... I works OK and like you've noticed, less angle is less problem.

Looking real good.
I also had the angling issue when I built my blade for my Sears. I ended up having to cut and weld the main plow mount to get the blade level.

Good ideas, I appreciate it!
