Operating a Kubota L345DT or its sister models requires accurate factory data. This 72-page Operator Manual (OEM #35370-19716) details the L305, L305DT, L345, L345DT, and L355SS tractors. The guide dedicates 16 pages to the instrument panel and controls, mapping every switch, warning lamp, and shift lever. It also includes complete wiring diagrams for the L305/L345 and L355SS harness circuits with full color codes. Operating instructions span cold-weather starts, slope handling, and differential lock use, alongside a daily maintenance checklist and troubleshooting charts for engine, tractor, and battery faults. Stop guessing on specifications: rear wheel bolt torque is 196-226 N-m (145-165 ft-lbs), while transmission fluid capacity is 30 liters on 2WD models, 31 liters on the L305DT and L345DT, and 32 liters on the L355SS.

Kubota L305–L355 Series Common Problems This Manual Covers
Steering wheel hard to turn or fluid seeping from the column on the L345DT p. 58
Start by checking the power steering oil reservoir. The L345 and L355SS hold 1.5 L (1.6 U.S. qts.). Verify steering wheel free play is 20 to 50 mm (0.8 to 2.0 in.) per the adjustment chart on page 58. Inspect hose connections at the column base for leaks. If the level keeps dropping, schedule dealer service to inspect the seals.
Manual Section: Adjustments3-point hitch lift arms won't raise or respond to the position lever p. 59
Check hydraulic fluid level and condition in the transmission case. All models require SHELL DONAX-TD, Mobil Fluid 423, or Exxon Torque Fluid 56; wrong or degraded fluid is a common culprit. Clean the hydraulic filter every 300 hours per page 49. If fluid type and level are correct, review the hitch troubleshooting checklist on page 59.
Manual Section: TroubleshootingFrequently Asked Questions
What are the torque specs for wheel lug nuts on a Kubota L345DT?
For the rear wheels, the torque specification for the bolts is 196-226 N-m (20-23 kgf-m, 145-165 ft-lbs). For the front wheels, the torque specification is 127-147 N-m (13-15 kgf-m, 95-110 ft-lbs). Always retighten bolts to the specified torque any time they are loosened.

Document Quality
This document is a scanned PDF, not a native digital file. An OCR layer has been applied, so you can search and copy the text, though the text quality is not perfectly crisp and shows minor scanning artifacts. Diagrams and illustrations are raster images, generally clear with readable labels, but they may pixelate when highly magnified. Page condition is fair, with some background discoloration and occasional specks, and there are a few blank filler pages present.
