Description
The Needham Ag 60 series seed boot bushing kit is designed to install within one row of a seed boot mounted to a John Deere 1560 or 1860 (with the two-piece seed boot) The kits includes two 7/16″ ID x 5/8″ OD bushings, plus a grade 9 x 7/16″ bolt and a grade 9 x 7/16″ lock-nut (with loc-tite to stop the nut coming loose over time).
Needham Ag Seed Boot Bushings are manufactured from a high grade, heat treated stainless steel material to provide excellent durability, no corrosion and long life. The bushing kit also allows growers to move the boot from the middle hole to the lower hole in the arm, such as what’s required when seeding small seeds (including canola or alfalfa) less than 1” deep.
How are the bushings installed?
First, using a heavy drill press, the existing holes within the top portion of the 60 series seed boots need to be drilled out with a 0.635” drill bit (see below). Next drill out the C shaped bracket which holds the seed tube within the seed boot. The 2 x 5/8” bushings are next inserted into the seed boot lugs and the boot is installed on the arms using the 7/16 bolt and nut. Once the nuts are torqued, the bushings clamp tightly to the arm, so the boots pivot on the bushings. This is a long term fix, plus by extending the pivot points outwards it helps eliminate play over time.
The YouTube Video below illustrates how the seed boot bushing kit works with the John Deere 50 series, but the principals are the same.
