Mowers TRIZ Cases

A pivoting trimmer arm lets zero-turn mowers cut edges without a separate tool.

A spring-biased coupler keeps twin drive levers aligned, enabling one-handed straight travel while preserving differential steering.

A movable gate and rear deflector create temporary crop storage, keeping the harvester running during receiver mispositioning.

A constituent sensor measures sugar content in extractor airflow to identify small or shredded billets and guide operational adjustment.

Sensors and actuators automate mower headland turns by raising the implement, shifting position, and aligning traction unit around windrows.

This agricultural machine uses a normally open hydro-mechanical clutch and oil bath to improve shutdown safety, cooling, and clutch life.

Spring- and damper-supported arms automatically adjust insect-scaring position around obstacles, reducing manual intervention during mowing.

An operator-adjustable solenoid valve modulates hydraulic flow, balancing fast cutting-unit lifting with stable motion across engine speeds.

Hydraulic line switching reverses blade rotation for serrated or smooth vegetation cutting.

This case uses sensors and a gear-driven rotating return tube to align openings with grain flow, improving distribution and reducing loss.

Handlebar pivot force sensing drives an electric motor, adapting walk-behind equipment speed to terrain and operator input.

A harder coating on cutting edges and uplift areas helps mower blades resist wear, extending service life and reducing maintenance.

Sensor feedback automatically positions concave covers and adjusts rotor speed for better grain separation across crop conditions.

An electric blower injects air into the discharge chute to prevent wet trimming buildup despite changing blade speeds.

Grooves and removable clamping rods secure cutting wires while enabling fast, single-operator replacement without specialized tools.

This case shows how a backsheet extension and variable-diameter auger segments help prevent material loss while preserving crop engagement.

Ultrasonic Doppler measurements track airborne grain and MOG velocity, improving fan and sieve adjustments while reducing grain loss.

A robust coupling lets the drive handle move laterally and adjust in height, improving access around hedges and trees while limiting wear.

This case shows how a pivoting C-shaped grip enables forward, rearward, and angular adjustment for comfortable portable tool operation.

A retrofit concave kit varies openings along the rotor to reduce clogging, grain loss, and MOG entry across crop conditions.

This handle uses a 20°–70° thumb support, rounded hand support, and positioned controls for comfortable trimmer operation.

This trimmer head uses a flexible sealing ring and spring-reset control assembly to block clippings and dust during wire release.

A hydraulic pump driven by crop-cutter motion powers the auger, enabling independent speeds without a bulky header gearbox.

Pivot joints position sensors across the agricultural header for field and height monitoring, then retract the arms for compliant transport.

Light emitters and detectors measure MOG between stalk rollers, enabling automatic adjustments that improve cleanup and reduce yield loss.

Pressure sensors compare supply and return conduit pressures to detect rotor slugging and enable timely load management.

Forward-looking and component sensors update biomass conversion during harvest, enabling proactive ground-speed and subsystem adjustments.

Segmented conveying ribs redirect edge grains onto the belt, limiting crop loss, accumulation, and oil contamination.
