Part of the Kubota Operator Manuals.
This is the factory Kubota operator manual for the GR2846A front-mount snowblower (publication 77700-03964), covering units from serial 21216879 and up. Across 42 pages it walks through assembly, wiring harness installation, operating controls, maintenance, lubrication, and a full parts breakdown for the snowblower, drive system, chute, and worm gearbox.
Use it to attach and remove the blower from the tractor subframe, wire the chute rotation controls, set drive chain deflection, service the gearbox, and replace the auger and impeller shear bolts with the correct grade 5 hardware. Torque values, lubrication intervals, and specifications are included so you can service the machine to spec rather than by guess.
Delivered as an instantly downloadable PDF you can read on any device or print for the shop.

Quick Reference Specifications
| Specification | Value | Page |
|---|---|---|
| General Torque Specification Table | Values apply to fasteners as received from supplier dry, or when lubricated with normal engine oil. They do not apply if special graphited or moly sidulphide greases or other extreme pressure lubricants are used. These values apply to dry conditions; under lubricated conditions reduce by 25% the torques in this table. Torque tolerance +0%, -15% of torquing values. Unless otherwise specified use torque values listed above. | p. 41 |
