Part of the John Deere Repair Manuals.
This 699-page John Deere 6105E, 6120E, 6135E Repair Manual (TM608619) is built for the 2015 utility tractor lineup, and it names the family once before you're into model-specific torque and clearance calls. You get a full Engine Repair section, complete Electrical System groups, and page after page of Hydraulics procedures covering the pump, oil cooler, hitch valve, and rear selective control valve. Inside you'll also find Steering and Brakes, Drive Systems, and full Cab and Operator Station teardown groups. Torque the hydraulic pump-to-top cover socket head screws to 125 N-m, and set the main pump screws at 120 N-m before you button anything up. No more flipping through a parts-store binder hoping the numbers match your serial number. This PDF carries working bookmarks, so you jump straight from Engine Repair to Hydraulics without scrolling past 500 pages you don't need.

John Deere 6105E, 6120E, 6135E Common Problems This Manual Covers
John Deere 6105E, 6120E, 6135E DEF system error code ACU-1020 and unexpected engine shutdown
Test the fluid to ensure a proper DEF concentration of 31.8–33.2% urea as specified on page 72. Drain the tank and flush the lines if the fluid is contaminated. Replace the DEF dosing unit filter to clear the fault and restore normal operation.
Manual Section: Fuel, Air Intake, and Exhaust Systems p. 72Error code ACU-1035 and severe loss of engine power under heavy load with no warning lights
Remove latch (A) and cover (B), and pull out primary air cleaner element (C) following page 142. Inspect the housing for heavy dust buildup. Pull out secondary air cleaner element (D) on page 143 and replace both filters to clear the restriction and restore airflow.
Manual Section: Fuel, Air Intake, and Exhaust Systems p. 142Contaminated fluid and old oil filters triggering hydraulic system overheating and sluggish implement response
Inspect the pump housing for leaks and tighten the hydraulic pump-to-top cover socket head screws to 125 N·m (92 lb·ft) using the sequence on page 404. Drain the contaminated fluid. Install a new oil filter and refill the reservoir to the correct level.
Manual Section: Hydraulics p. 404Incorrect linkage adjustment triggering transmission grinding during shifts and poor clutch engagement
Measure the clutch pedal linkage clearance. Adjust the interlock cable to achieve a clutch pedal free travel of 32 ± 5 mm (1-1/4 ± 3/16 in.) as shown on page 336. Tighten all locknuts securely and test the tractor for smooth gear engagement under load.
