Rebuilds start with the factory document, and this 607-page reference (OEM #9Y111-01120) covers all three machines: the M59 tractor, the TL1350 front loader, and the BT1200 backhoe. Wiring diagrams map ECU logic, HST pedal sensors, and the engine start/stop circuit. Hydraulic schematics trace every line from the front loader control valve through the backhoe boom and bucket cylinders. All 11 systems sit here, from EGR and crankshaft teardown to hydrostatic transmission, differential gears, brakes, and steering, backed by torque tables, troubleshooting steps, and exploded views. Torque the TL1350 loader mount bolts to 167 to 196 N·m; set the BT1200 boom cylinder head between 950 and 1000 N·m. When the machine is down, those numbers beat a forum guess. The PDF opens on a laptop, tablet, or phone and is bookmarked for quick jumps, so you can read it right at the machine.

Kubota M59, TL1350, BT1200 Common Problems This Manual Covers
Kubota M59 TL1350 hydraulic pump whining noise under load, insufficient boom speed and bucket won't lift p. 404
Test the cylinder safety valve operating pressure on page 404 and verify it reads 19.7 to 22.5 MPa. Replace the hydraulic oil filter if over the 200 Hr interval. Torque hydraulic hose retaining nuts (3/4) to 35 to 41 N·m.
Manual Section: Hydraulic System TroubleshootingBoom cylinder leaking fluid down the rod, excessive cylinder movement and individual circuit feels weak p. 585
Drain the fluid and pull the boom cylinder. Fit new piston seals and O-rings, but do not turn (roll) the piston seal as you install it (page 542). Reassemble, then torque the boom cylinder head to 950.0 to 1000 N·m as shown on page 585.
Manual Section: 11 BackhoeError display on LCD screen, transmission oil over heats and machine will not stop in neutral position p. 230
Check the error code reference to identify the specific HST system fault. Drain the fluid and verify the transmission case capacity is refilled to exactly 46 L (12.2 U.S.gals, 10.1 Imp.gals). Inspect the shift linkage mechanism for binding or worn components.
Manual Section: Transmission Troubleshooting (HST System)Front end loader bucket drops by its weight, self-leveling does not work and excessive joint play p. 527
Measure the pin to cylinder pin hole clearance and confirm it falls within 0.10 to 0.38 mm as specified on page 527. Replace worn pins and bushings if clearance exceeds the limit. Torque the front frame to loader frame mounting bolt and nut (M14 9T) to 167 to 196 N·m.
Manual Section: Front Loader TroubleshootingFrequently Asked Questions
How do I reset the Kubota M59 service or maintenance light?
To reset the service interval alert, hold both the display mode switch (2) and the travel speed switch (3) for two seconds or more while the hour meter (Normal Display 1) is showing. That clears the periodic maintenance alert.
What are the torque specs for Kubota M59 wheel bolts, loader pins, and backhoe mounting hardware?
On the Kubota M59, torque the front wheel mounting nuts to 196 N·m (20 kgf·m, 145 lbf·ft) and the rear wheel mounting nuts to 260 N·m (27 kgf·m, 192 lbf·ft). Loader frame mounting bolts (M14 9T) require 167 to 196 N·m (17.0 to 20.0 kgf·m, 123 to 144 lbf·ft). Backhoe step mounting screws are 48.1 to 55.8 N·m (4.9 to 5.7 kgf·m, 35.5 to 41.2 lbf·ft), and backhoe cylinder support mounting screws are 300 to 430 N·m (30.6 to 43.8 kgf·m, 222 to 317 lbf·ft).
What do Kubota M59 error codes or warning lights mean?
ERROR-00 flags a failed electronic instrument panel memory device, and ERROR-20 points to a communication error between the ECU and that panel. Warning lights include 'FUEL' on the LCD when fuel drops below 5 L (1.32 U.S.gals.), plus 'OVERHEAT' and 'Eng SLOW' when coolant temperature hits 125 °C (257 °F) or more.
How do I reset the Kubota M59 hydraulic system after a fault or air lock?
After installing the front loader, bleed air from the hydraulic system by operating the control lever. For the steering system, start the engine, then turn the steering wheel slowly in both directions alternately several times, and stop the engine to bleed air.
What do I get after purchasing this Kubota M59, TL1350, BT1200 manual?
Immediate download of the complete 607-page searchable Workshop Manual. Read it on any device, whether a laptop at your desk or a phone out in the field.
