I would like to nominate my Four Wheel Drive Allis-Grader for this month’s contest. For those of you who are not yet up on the proper pronunciation of the term, the "s" is silent therefore this creation is pronounced "Al-E-Grader”
We moved to our lake property in winter of 2005 and now have about 600 foot of driveway to maintain. I had a box blade for the rear of my ford LGT
145 and my brother has a small Kubota with a back blade. These both worked OK but still left some "whoop-de-dos" and seemed to make the humps and holes grow instead of smoothing them out. So off I go to cyber space to see what was available that would do a better job. I ended up surfing many sites that had some good practical info regarding the advantages of a center mount grader blade over a rear mount. As I now considered myself more educated on graders in general, I decided to round up what I could find around here and build a center grader blade. This first blade was made from an old MTD plow swivel, cut up sides of a 100 pound LP tank and parts from a cub cadet mower carrier. I used this under my Allis Chalmers 919H with very good success. BIG difference over the rear mount blades and I was able to set the blade square and at an angle either direction. I hooked up a solid lift link and could raise the front of the tractor off the ground when lowering the blade down all the way. I used this grader blade and tractor for 5 years or so and was real happy with the outcome. But thanks to the info I had learned surfing about graders, swirling around in my head was an idea or two on what could be done to make it better.
In early spring of 2010 I found a CL buy close enough to go for a trip. I picked up a 1977 A/C 700 series with no engine, but in real good shape with a 3 speed with high low. When I got it home it was such good shape that I hated to disassemble it and thought I should just park it out back for a while and get working on a Simplicity 3314H that I had gotten earlier for a parts machine. As the simplicity came apart and I got down to the front end disassembly, the proverbial light bulb went on above my head. Out comes the reciprocating saw and some c-clamps, a 2x4 to support the hood and here was a mock up of a longer wheelbase tractor to use as a grader. Granted there was one too many sets of front tires on my prototype but the thought was there.
So the day came when I got ready to weld the two front ends together and I ended with this 13 inch extension, (a little shorter than my prototype). Then I thought about the extra rear end I had and figured, "Why not" and so the idea was born. After attaching and connecting the second rear end, adding the 16 HP Briggs and rewiring the Allis-Grader from its Kohler beginnings, she was put to driveway duty with the blade I had used on the 919H. And a darn fine job she did too.
But being the kind of guy I am, I knew there was still room for improvement. I decided the A-G needed a different “Grader-Like” blade with more adjustments keeping the side to side swivel by using a circle like a motor grader, blade angle to ground so I could cut slopes and blade tilt front to back for digging or smoothing. This was mostly built as I went along, again with what I could find laying around, but I started with a good basic idea and a car brake rotor as my “Circle”. Using some scrap steel I had, a blue dish shaped steel piece and some welding rod I came up with this. Now it was time to add the electric lift I had as this new Grader Blade creation weighed in at about 160 pounds.
The brake rotor with blade attached spins in a welded circle with the blue disc as the top support for the hanger. There is a stop bolt at both front “corners” of this circle that allow me to adjust the blade to any angle short of the rear tires. The front of the hanger attached at the front axle mower attachment points. But I could not get the side movement I wanted and after a few attempts I ended up with this as my height adjustment (the top piece in picture), one each side, which gives me a side to side lift height of 6 inches high right and seven high left. This was after figuring out that an upside down trailer ball hitch would give me the best swivel on the front end of the hanger, instead of the mower mount points on the axle. My new blade was even better, my prototype was built and proven and now time for some cosmetics.
I eventually welded the two hoods into one, added two sets of Carlisle Ag tires, a toothed scarifier bar in front of the blade, put a deep cycle battery in front of the motor with some extra grill work to cover the space on the sides, used cans upon cans of spray paint, and the current Allis-Grader now looks like this, with a short action video.http://www.youtube.com/watch?v=ZMXJvBZC52Q
Good luck to all and let the games begin
add a few pics and correct some weirdness in my story
