Description

Landini Legend 125-185 Training Manual – Techno, Top & Top Tronic

This is the full Landini training manual for the Legend series tractors, covering the 125, 135, 145, 165 and 185 models in all three build configurations: Techno, Top and Top Tronic. It is the workshop reference (publication number 3681702M1) used for technical specifications, mechanical and hydraulic layouts, wiring diagrams, operating instructions, adjustments and troubleshooting for the complete Legend range.

The manual is written for assistance technicians who already have practical training on the tractor, so it focuses on the data and procedures a working mechanic actually needs: measured values, torque figures, adjustment sequences, pressure test points, calibration routines and diagnostic alarm codes.

What This Manual Covers in Practice

The scope runs from the flywheel to the rear PTO. The transmission chapter breaks out the Techno double clutch and mechanical reverse shuttle, the Top version with single clutch, Power-six unit and mechanical reverse shuttle, and the Top Tronic version with damper disc and Deltashift electrohydraulic module for reversing and three ranges (underdrive / direct / overdrive). The gearbox is documented with six synchronized helical-toothed gears, three ranges and an optional creeper with a 5.357 reduction ratio. Rear axle coverage includes bevel gear pair adjustments, differential lock, 4WD engagement and PTO, plus side final drives in both flanged and sliding versions.

Hydraulic coverage separates the low flow circuit (power steering, differential lock, 4WD disengagement, Powersix, PTO and PTO brake) from the high flow circuit (trailer brake, auxiliary control valves, power lift, electrohydraulic flow selector). Pressure test procedures with dedicated IDR unions are given for each user.

The mechanical power lift chapter documents position, draft, mixed and floating control, the valve system in neutral, lifting and discharge phases, and step-by-step adjustment on both bench and tractor. The electronic power lift chapter covers the Bosch control unit, console, sensors and the Shock Absorber function.

The electrical system chapter gives complete wiring for all three versions with connector pinouts, cable colour codes, sensor and solenoid valve identification and test procedures. Calibration procedures C3 through C6 are shown with the exact display messages (C3, AC-3, do, etc.) and button sequences.

Why This Manual Matters

Landini Legend tractors with the Deltashift module, electrohydraulic power lift, hydro-pneumatic front suspension and electronically controlled PTO cannot be serviced correctly without the factory reference values and adjustment sequences. This manual supplies the torque figures, calibration routines, alarm code definitions and pressure settings that let a technician diagnose and repair the machine instead of replacing parts by guesswork.

The troubleshooting chapter alone – with alarm codes for the clutch pedal potentiometer, Deltashift speed sensors, engine rate sensor, Park Lock switch, reverse shuttle lever, clutch solenoid valves, underdrive / overdrive / reverse solenoid valves, enabling microswitches and transmission oil temperature sensor – can save hours of diagnostic time.
