Keep your John Deere 17G mini excavator operating reliably with this aftermarket bottom roller assembly from United Skid Tracks. Bottom rollers are a critical undercarriage component, supporting the weight of the machine during travel and digging while guiding the track for smooth, consistent operation.

This bottom roller is a direct aftermarket replacement for part numbers 4340393 and 4640798. It is a single-flange, inside-guide style roller built to original specifications for proper fit and long-term performance.

Manufactured with high-quality seals, this roller is designed to keep dirt and debris out while retaining lubrication for extended service life in demanding jobsite conditions.

Installation is straightforward, using two bolts to secure the roller to the track frame. These rollers can typically be installed without fully removing the rubber track, making replacement a convenient on-site repair.
