Part of the Kubota Repair Manuals.
This Kubota Workshop Manual is the service supplement for the ZD326RP and ZD331RP zero-turn mowers, built around the D1005-E3-ZD-2 and D1305-E3-ZD diesel engines. Its 42 pages give the additional and altered functions of these RP models over the ZD326 and ZD331.
The manual is organized in Information, General, and Mower parts. You get identification, lubricant and coolant data, tightening torques, the maintenance check list, and then the mower power transmission, troubleshooting, servicing specifications, and checking, disassembling, and assembling procedures.
Owners and independent mechanics use it for deck and drive work with factory values, from mower blade screw torque and bevel gear backlash to pinion shaft turning force. It notes that items not covered here refer back to the base ZD321, ZD323, ZD326, and ZD331 workshop manual.
