John Deere BXX10720: Inner Drive Sprocket Mud Scraper Attachment Chain

Continuously removes bulk debris from the sprocket hub and discards it to the outside of the track assembly while the tractor is in forward motion.. Designed to significantly reduce mud, sand, rocks, and other potential buildup in the track assembly, while also increasing track belt life by discarding debris directly to the ground rather than on the track surface.. Kits are available in two sizes depending on wide- or narrow-track undercarriage.. Compatible with 9RX (serial number 820001- ) wide track models with belt width of 762 mm (30 in.) and 914 mm (36 in.). Includes four scrapers, one for each drive wheel (enough for one complete tractor).. Enhanced Performance and Longevity: Both kits are designed to significantly reduce mud, sand, rocks, and other buildups in the track assembly, increasing track belt life by directing debris to the ground instead of allowing it to accumulate on the track surface
