50 Series Firming Wheel Arm Upgrade – For all 750 after serial number 3835, and ALL 1850 air-seeders.



As acres accumulate on John Deere drills and air-seeders, the pins (welded to the factory firming wheel arms) wear and they can’t be replaced without replacing the whole firming wheel arms.

Our firming wheel arm upgrade kit replaces the factory firming wheel arm with a new one which also allows the pin to be replaced (just like the newer 60 & 90 series firming wheel arms).


  • Comes as a kit, which includes a high quality steel arm and high quality precision ground pin to improve service life.
  • Same arm works on both the RH and LH side.
  • Comes with our high quality seals and poly bushings.
  • Comes with a 4 ¼” Grade 8 Flange bolt, Grade 8 flange nut and 1” ID Grade 8 washer.

NOTE: A free firming wheel arm removal/install tool (worth $70.00) is shipped free with 24 (or more) rows of the 50 Series Firming Wheel Arm Upgrade Kits.
