Assembly and System Documentation
The 2006 Fendt Farmer 400 manual provides a technical overview divided into logical main assemblies, mirroring the official factory documentation structure. Detailed sections address the 1000-series transmission, including differential and axle drive control modules, as well as the 2000-series engine block, cooling, lubrication, and fuel injection systems. The documentation further maps out the front axle suspension with leveling accumulators and hydraulic equipment, focusing on the load-sensing pump assemblies. Understanding the 9000-series electronic diagnostics for instruments and CAN bus communication is critical for accurate fault isolation and repair planning. Always verify factory pressure baselines and safely bleed hydraulic lines before interacting with load-sensing components to prevent severe physical injury.
Engine, Transmission, and Hydraulic Reference Values
Factory specifications are clearly defined for rapid shop reference. The engine cooling system thermostat opening is documented at 87 ± 2 °C. The 400-series transmission high-pressure forward and reverse values are strictly listed at 550 ± 20 bar. Fendt Farmer 400 hydraulic system pressure is specified at 200 bar, with auxiliary pump flow rates reaching 110 l/min on select models. Final assembly requires precision tightening. Rear wheel nut torque values are set to 450 Nm, while front wheel nuts require 275 Nm.
