Single-axis agricultural machine with continuous speed variation and independent power take-off
20240367510 · 2024-11-07 ·

A single-axis agricultural machine with continuous speed variation and independent power take-off includes an internal combustion engine, a clutch assembly, wheels, a power take-off for work tools controlled by a gearbox, and a guide handlebar with controls. A primary shaft extends from the clutch assembly and controls a gear reduction, at the output of which a coupling transmits the motion to a shaft of the power take-off. A hydrostatic assembly draws motion from the internal combustion engine through the clutch assembly, a first kinematic chain being coupled thereto, and is connected to a second kinematic chain that retracts in the gearbox and that controls an axle of the wheels through a final reduction. Three shaft assemblies transmit motion respectively from the engine toward the power take-off, from the engine toward the hydrostatic pump, from the hydrostatic motor to the final reduction, and from the final reduction toward the wheel axle, the three shaft assemblies being arranged orthogonal to each other.
