This is the Kubota T1880, T2080 and T2380 riding mower Workshop Manual (publication 9Y111-01106), a 585-page PDF for anyone servicing these lawn tractors. It documents both the mechanism and the servicing of the whole machine and folds in the full engine service manuals for the Kohler power units.
Machine coverage includes the engine, the hydrostatic transaxle, brakes, front axle, steering, the fender and lift system, the PTO system, the electrical system with the KRA reverse awareness circuit, and the mower deck and blade drive. Two complete Kohler engine service manuals are bound in: the Courage SV470 to SV620 and the 7000 Series KT715 to KT745.
Use it to troubleshoot a weak hydrostatic drive, set blade and pulley torque, adjust the brakes, follow the wiring diagram, and rebuild the Kohler engine to factory spec. It is a downloadable, printable PDF for the shop or the yard.
