He Overhauled The Pivot Arms That Hold Double Disc Seed Openers On Deere Drill
 ✖  |
Stuart Gunness, 6220 165th Ave. S.E., Walcott, N. Dak. 58077 (ph 701 372-3761): "I overhauled the pivot arms that hold the double disc seed openers on my 1992 Deere 9300 40-ft. drill. I used bolts and bushings instead of replacing the original rivets. The problem is that when the rivets wear out, the piece the arm pivots on also wears out. Replacing the rivets and this piece costs about $16 per arm.
"I removed the rivets and drilled out the piece that the arm pivots on to 3/4 inch. Then I moved the pivot arms from outside the disc opener to the inside. Then I installed two bushings (JD part no. A41207), a 3 1/2-in. length of 1/2-in. pipe as a spacer, and a 7/16-in. bolt to reassemble it. The pipe keeps the bushings from twisting as they wear.
"I made the conversion four years ago and installed new discs at the same time. It was a big job, but I saved a lot of money. I paid $1 apiece for the bushings. My total cost was only about $3 per set of disc openers. The same idea would also work on older Deere LLA drills."
