Rexroth A4VG hydraulic pump for Aebi Schmidt TT270 TT275 lawn tractor 1502477 1014407 1107628-4 0270850-1 1047931-4 0270843-6

The Rexroth A4VG series variable-displacement axial piston pump is a key hydraulic component integrated into specialized snow removal and grounds maintenance equipment such as the Aebi Schmidt TT270 and TT275 multifunction tractors. Designed for closed-loop hydrostatic transmission systems, this high-performance pump is engineered to deliver the precise, reliable power required for demanding municipal and airport operations.

In the TT270/TT275 platform, the A4VG pump typically functions as the central drive unit, converting mechanical power from the tractor's diesel engine into variable hydraulic flow. Its axial piston, swashplate design allows for smooth, stepless speed control of the vehicle's travel functions, providing exceptional traction and maneuverability in varied conditions, from snow clearance to lawn mowing.

Key operational advantages for this application include high power density, robust construction for continuous duty cycles, and high overall efficiency, which contributes to lower fuel consumption. The pump's variable displacement capability enables optimal power matching to the immediate load demand, whether for slow, high-torque plowing or transport travel. Integrated controls, such as the HD (hydrostatic displacement) controller, facilitate precise speed regulation and responsive handling.

Built to withstand harsh environmental conditions—including temperature extremes, vibration, and contamination—the A4VG ensures high system reliability and durability, which is critical for winter service vehicles with minimal downtime requirements. Its design also supports the integration of auxiliary functions, potentially powering various front- or rear-mounted implements.

In summary, the Rexroth A4VG pump provides the TT270/TT275 tractor with a sophisticated, efficient, and robust hydrostatic drive core, directly enabling its versatile, high-productivity performance as a versatile grounds care and snow removal unit.

Q1: What is the primary function of the Rexroth A4VG pump in the Aebi Schmidt TT270/TT275 tractor?

A1: Its primary function is to serve as the central drive unit within a closed-loop hydrostatic transmission system. It converts the mechanical power from the tractor's diesel engine into variable hydraulic flow, providing stepless speed and torque control for the vehicle's travel functions, enabling precise traction and maneuverability.

Q2: What key design feature allows the A4VG pump to provide variable speed control?

A2: The key design feature is its axial piston and swashplate configuration. By changing the angle of the swashplate, the displacement (volume of oil pumped per revolution) is varied. This allows for smooth, continuous adjustment of hydraulic flow and output speed without needing a gearbox.

Q3:What is the price and delivery time of the Rexroth A4VG pump for Aebi Schmidt lawn tractor？

A3: The specific price and delivery time will depend on the equipment model or specific product model you provide.
