Used Hydraulic Motor

Used earthmoving spare parts: hydraulic motor – operation within the agricultural circuit

The hydraulic motor converts the energy of pressurized fluid into rotary mechanical motion transmitted via the output shaft. In a closed or open hydraulic circuit, the hydraulic pump generates the flow rate, the hydraulic distributor directs the flow, and the motor delivers the rotational power. The motor’s displacement, maximum service pressures, and volumetric efficiency directly determine the torque available at the output shaft.

In agricultural machinery, the hydraulic motor drives shredder rotors, forage harvester wheels, cleaning fans on combine harvesters, and baler drive systems. Its durability largely depends on the quality of the supplying circuit: filtered oil, controlled pressures, and flow rate adapted to the displacement.

Slow or fast hydraulic motor: selection criteria by rotation speed

Choosing the right hydraulic motor relies on several parameters to be considered before ordering:

• Displacement: high for slow, high-torque motors (wheel drives, conveyors), low for fast motors (fans, high-speed shredders)
• Rotation speed: from a few dozen rpm for orbitals to several thousand rpm for high-speed gear motors
• Service pressures: to be matched with the hydraulic pump capacity of the tractor or carrier machine
• Output shaft: type, diameter, and keying must correspond to the driven component or the intermediate gearbox
• Rotation direction: single or bi-directional depending on the application (auger, reversible conveyor, fertilizer distributor)
• Nominal flow rate: to verify based on the available flow from your tractor or self-propelled machine’s hydraulic outlet

Gear, orbital, or piston motor: used technologies

Three main families of hydraulic motors are found in agricultural equipment. Gear motors are simple, robust, and economical, suited for high-speed applications like cleaning fans. Orbital motors (gerotor type, from Danfoss or Sauer technologies) provide high torque at low speed for slow drives: conveyors, feed belts, cutting mechanisms. Piston motors, axial or radial such as Poclain, deliver the highest power and equip hydrostatic transmissions of combine harvesters or telehandlers’ axles.

Each technology balances output power, compactness, volumetric efficiency, and cost. Used motors from all three families are available at TMC Bejenne, allowing you to select the best technology for your application without budget constraints.

Case TP France: Used agricultural hydraulic motors available at TMC Bejenne

Since 1945, TMC Bejenne has dismantled agricultural machines of all brands on its 11-hectare yard in Naintré. Extracted hydraulic motors are inspected in the workshop before entering our stock. You will find motors from equipment by Case IH , John Deere , New Holland , Massey Ferguson , and Claas . Our 25,000 references cover the majority of replacement needs for tractors, combines, balers, and telehandlers.

• Combine harvester hydraulic motors: rotor, cleaning fan, grain auger
• Orbital motors for conveyors, cutting units and feeding systems
• Rotation and translation motors for telehandlers and self-propelled machines
• Motors for augers, mower arms, and tractor-mounted equipment
• Bi-directional motors for reversible conveyors and fertilizer distributors

Used hydraulic cylinders: lift, tipper, and agricultural trailers

The hydraulic cylinder is the component under the highest stress in the agricultural hydraulic circuit. Each day’s startup sees lift cylinders front and rear, hood openers, steering cylinders on telehandlers, or tipper cylinders working under maximum pressure. A leak, worn seal, or scratched rod can immobilize the machine at the worst time.

TMC Bejenne offers a wide choice of inspected used hydraulic cylinders, derived from dismantling tractors, combines, and attached equipment. Tractor lift cylinders, support legs for agricultural trailers, tipper and slurry tank cylinders, combine body cylinders: each part is checked in the workshop before shipping. Buying used offers substantial savings compared to new parts, whose costs can quickly exceed several hundred euros per original piece.

Pump, distributor, and hydraulic unit: used agricultural parts

A high-performance hydraulic motor only functions properly when paired with a well-sized circuit. TMC Bejenne also stocks other system components:

• Used hydraulic pumps: flow and pressure tested, compatible with tractor, combine, or self-propelled machine
• Used hydraulic distributors: single or multiple effect, for lift, hydraulic PTO, or mounted equipment
• Hydraulic leg for trailer: support cylinders taken from dismantled agricultural trailers
• Used hydraulic groups and power units: complete blocks from self-propelled machines or telehandlers, available to replace a failed unit at a lower cost
• Hydraulic suspension block: for tractors with suspended cabins or self-propelled machines

This allows you to rebuild a failed hydraulic circuit entirely with used parts, saving significantly on overall repair costs.

Motors for augers, rotation, and bi-directional use: agricultural applications

Used agricultural hydraulic motors cover a wide range of field applications that new parts often make too expensive to replace. Rotation motors drive augers, forage harvester rotors, and corn pickers, while translation motors propel the hydrostatic axles of combines or sprayer self-propelled machines. For tractor-mounted augers, the high-torque, low-speed orbital motor is the benchmark solution, directly supplied from the tractor’s hydraulic outlet.

Bi-directional motors allow control of reversible conveyors, fertilizer distributor arms, or baler feed belts. In all cases, selecting a used motor correctly identified by our technicians avoids reference errors and costly returns. Call 05 86 24 00 26 to quickly identify the part compatible with your machine.

Hydraulic motor price and power: the savings of used agricultural parts

At comparable power, a used hydraulic motor generally represents 30 to 70% savings compared to the price of a new component:

• Price based on technology: standard orbital motor, compact gear motor, high-power piston motor all have very different price levels, both upwards and downwards in used parts
• Output power: depends on flow (l/min) and pressure (bar) available in the circuit; our technicians help verify compatibility with your tractor or machine
• Displacement: key parameter to specify when requesting a quote to receive a fitting reference
• 15-day return policy if the component does not fit or function: real security when buying used parts
