Part of the Kubota Operator Manuals.
This is the operator manual for the Kubota GCK60-BX grass catcher, the rear-mounted collection system built for BX-series compact tractors running the RCK54-22BX or RCK60B22BX mower decks. It walks through setting up the blower, installing the bag frame, and connecting the discharge boot to your deck, plus day-to-day operation and upkeep.
Inside you get the full setup sequence, safety sign locations, a bolt tightening chart with torque values, operating steps for bagging and clearing plugged ducts, and scheduled lubrication intervals for the gearbox and driveline. A parts list with exploded views covers the blower drive, gearbox, boot and hose, driveline, and grass bag components.
Owners and mechanics use it to install the catcher correctly, keep airflow strong, and order the right replacement parts by number. The file is a downloadable PDF you can read on any device or print for the shop.
