If the weighing display fluctuates while the feed mixer moves or crosses uneven ground, potential causes include faulty load-cell wiring, a malfunctioning display, chassis or mounting damage, or improper electrical work. Inspect the equipment safely and have a qualified technician test the weighing system.

Hydraulic oil leaks may become worse when the hydraulic circuit overheats. Check the reservoir and pump sizing, hose and connector specifications, oil quality, filters and maintenance schedule. Never inspect a pressurised hydraulic leak by hand.

Cutting blades are wear components. Service life depends on forage abrasiveness, blade position, usage and material quality. Inspect cutting edges and mounting regularly, and replace damaged or excessively worn blades using the machine instructions.

Planetary gearboxes are used for speed reduction and torque transmission in agricultural machinery. Lubrication quality, correct oil level, shaft alignment and mounting conditions matter. Follow the specific gearbox manufacturer’s service requirements.

Changes in animal performance after new feed equipment is introduced may relate to ration formulation, mixing time, particle size, feeding behaviour and other management factors. Review the feeding plan with a qualified nutrition professional rather than assuming the machine alone is responsible.

Hydraulic oil, gear oil and grease should match the equipment requirements. Poor-quality or unsuitable lubricants and missed service intervals can increase wear and repair costs. Follow the manual and consult a qualified technician when faults occur.
