Allis-Chalmers Ripper Mounted On 3-Pt.
 |
“I wanted to tear up some headlands that had gotten compacted, but I wanted to mount the ripper on the 3-pt. on my International Hydro 84,” says Seltzer. “I cut off the snap coupler mount and after measuring some 3-pt. mounts I fabricated one for the subsoiler.”
The subsoiler frame consisted of a pair of steel bars that sandwiched the beam of the curved ripper tooth and came forward to the snap coupler. Seltzer ran a piece of rectangular tubing across the forward end of them. He welded short steel plates to the ends of the crossbar and drilled holes in the plates for the lift arm pins.
The top link connector was made with two 3/8 by 4-in. pieces of scrap iron. Two 3/8 by 3-in. steel supports were mounted vertically between the top link connector and the lower link crossbar.
“The top link is lighter as it doesn’t have that much stress,” says Seltzer. “I reinforced the crossbar, which gets terrible stress, by running pairs of 3/4-in. rebar from either end of the crossbar back to the joining of the frame and the ripper tooth beam. Since the ripper pulls from the center, these equalize the pressure to each 3-pt. arm.”
Adding the 3-pt. made the subsoiler top-heavy and awkward to move around. Seltzer added a forged 5/8-in. eyebolt to the balance point of the frame to make it easier to move.
“I used it on the headlands and also to rip through a pothole about an acre in size,” says Seltzer. “It gets about a foot and a half deep and opened up the ground to let the water through.”
Seltzer is unsure just how old the subsoiler is. A local machinery dealer who once carried Allis-Chalmers suggested it dates back to the 1950’s.
