My Homemade 4WD Mini Road Grader aptly named The Allis-Grader
Posted August 31, 2011 - 08:42 PM
Here is my still improving and always under construction but functional and very effective homemade "Allis-Grader" history with lots of pictures.
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-doos" 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.
Ended up at a site called roadgradingschool.com that had some good practical info regarding the advantages of a center mount grader blade over a rear mount, course they wanted you to buy their grader, which looks like it works great but way too large for me. But I did consider my self more educated on graders in general after going through their site. So I proceeded to round up some scraps and built me a grader blade that I used under my Allis 919H, used an old MTD plow swivel, cut up sides of a 100 pound LP tank, parts from cub cadet mower carrier. BIG difference over the rear mounts, worked real well, was able to set the blade square and at an angle either direction. Hooked up a solid lift link and could raise the front of the tractor off the ground when down all the way.
I used this blade and tractor for 5 years or so and was real happy with the outcome. BUT, thanks to the road grading school info, 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. Picked up an A/C 700 series with no engine, But in real good shape with a 3 speed with high low. Worth the drive at the price to be a parts tractor. When I got it home it was in really good shape, almost hated to disassemble it, thought should just park it out back for a while and get working in a Simplicity 3314H that I had gotten earlier and was going to part out for sure, I wanted the front clutch and the electric lift from the 3314, was also going to keep anything else I may need down the road for my other tractors from this and sell off the rest. As the simplicity came apart and I got down to the front end disassemble the proverbial light bulb went on above my head. Out comes the sawzall and some c-clamps, a 2x4 to support the hood and here is a longer wheelbase tractor to use as a grader.
Obviously the original set of front tires would come off, the engine could go in the original location to save the cost and hassle of longer driveshaft, etc.
So I am now thinking, " I can do this, I have a welder, not real good at it but gotta learn sometime, lots of scrap and leftover steel pieces around, and as long as I dont spend lots of cash, the wifes OK with most anything I do tractor wise".
So the day comes when I get ready to weld the two pieces together and I realize this would be too long, and probably kind of weak, so I end up with this
Added 13 inches to the front end. As I am standing their admiring my bad welds that darn light bulb went on again, (should of left the switch off), and I thought about the two old 3 speed A/C B112 tractors that I have sitting around growing rust. Are the gear ratios the same? Could I hook the two together and make it drive both rear ends? All sorts of questions I am asking myself????? But finally decided why not I did the front end and probably cant hurt it any worse and may get better at welding in the process.
So back out scrounging parts and stuff and got the two coupled together
Used what I could find around here and ended up making it so that I could remove the rear rearend if I needed or wanted to. Next step was to get the power back to the second rearend. Also built up a rod to connect the two shifters together.
Used the pulley and lever set up from the mower drive on the other side of the tractor to be able to drop the rear rearend out if needed.
Next was to get the rear seat deck centered over the tires. Had to add some metal here to get the right set back.
Also wanted the rear support to be fairly sturdy as I was thinking a dump bed, so added some steel here too.
And under the deck
So this is what I ended up with, both hoods on for visual purposes.
The AC 710 originally came with a Kohler, so I had some rewiring to do for a permanent install of the 16 HP Briggs I had but as I was anxious to take it for a spin I did a temporary hookup with the fuel tank in sideways and the battery setting up front, as well as the muffler setting askew.
Ended up with about a 14 foot outside turning radius. Discovered it was easier to turn going backwards and found out that my shifter connection needs some refinement after I stopped while going over some of the bumps in the front yard, needed a little extra twist to get the rear rearend in gear. Course this happened as Kathy was watching me out the front window. She asked if I broke it already and I told her it was a design error, not a break down.
Eventually got the wiring all switched over for the Briggs. Added the starter generator and took off the original starter as the nose gear was stripped. Started it up and the only smoke was from the exhaust, none of that bad smelling electrical smoke. Did pretty good on the rewiring for a color blind guy.
This was to be my new blade, donated to the project by a friend.
but I had lots of Ideas regarding blade mount so for now time to try it with the old blade.
These were the only pictures I could find of the original blade I made for the 919H,
added 13 inches to the attachment arms to get it at the right spot under the grader.
In action shots to follow
OK going to stop for now and will get to the rest of the story with in the next few days

Also, for the record, tractormike named his the "Allis-Gator" and this project is the "Allis Grader"

I am blond.
wvbuzzmaster you are correct on all accounts. I stand corrected. He did have to separate shift levers on that one. If I wasn't bald I'd think I was blond.:rolleyes:

Casey, we now know what your 'problem' is. Anybody got some 'blond' jokes?
P.S. This would be a great entry into the featured tractor thread.
