Part of the Kubota Repair Manuals.
This is the factory operator manual and parts catalog for the Kubota B2550 front-mount snowblower, publication number 70060-03613, covering units with serial number 0200101 and up. The 38-page PDF walks you through assembly onto the tractor, operating controls, snow removal technique, seasonal maintenance, and dismounting at the end of winter.
The second half is a full illustrated parts section, with exploded diagrams and Kubota part numbers for the push frame, drivelines, snowblower head, worm gear box, reduction box, and chute rotation system, including the optional electric chute and deflector kits. A torque specification table and lubrication intervals round it out.
Whether you are setting the blower up for the first time, chasing a rotation or shear-bolt problem, or ordering a replacement part by its exact number, this manual gives you the information straight from Kubota.
