Description
The 50 series seed boot bushing kit is designed to install within one row of a John Deere 50 series opener, such as a 750. The kits includes a tapered bushing, a parallel bushing, plus a grade 9 x 3/8″ bolt and a grade 9 x 3/8″ lock-nut (with loc-tite to help 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 without 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 often required when seeding small seeds (including canola or alfalfa) less than 1” deep.
IMPORTANT, if your middle hole on the drill has been drilled out and a bushing was installed into the opener arm, we don’t recommend using the Needham seed boot bushing kit, as the boot can no-longer be aligned flush against the disc.
The kits includes two 3/8″ ID x 5/8″ OD bushings, plus a grade 9 x 3/8″ bolt and a grade 9 x 3/8″ lock-nut (with loc-tite to stop the nut coming loose over time).

If your buying our pre-drilled 50 series seed boots, no drilling is required (NONE on the drill or seed boot).
If your wanting to add our bushing kit to existing seed boots (not the Needham brand pre-drilled ones), the existing two holes within the top of the 50 series seed boots will need to be drilled out with a 0.635” drill bit, which we have available. This will require a heavy drill press to drill them out, ideally one that weighs 500 lb or more. Once the boot mounting holes are drilled out, the 2 x 5/8” OD bushings are inserted into the seed boot lugs and the boot is installed on the arms using the 3/8″ bolt and nut. Once the nuts are torqued according to the instructions, the bushings clamp tightly against the lugs on the opener arms, 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.
