planetary drives

Transmitting power without losses
Pro-Drive planetary drives generate an absolutely linear stroke length. Force progression and knife movement are just as linear. The torque available is converted into a linear stroke of the knife without almost any losses. This is the key for maintaining the efficiency of the cutting system especially in difficult harvest conditions.

The Schumacher range of drives offers the perfect solution for every cutting system.

Maximum rotor speed: 600 rpm

Sensor technology for knife drives

The use of sensors on a knife drive allows us to implement a technology that collects data on the cutting system and evaluates these for the purpose of optimizing the throughput. The technology instantly detects any variations in the crop stand for adapting the current forward speed and maintaining a consistent flow of material into the machine. It also detects damage from impacting an obstacle.

Solutions for your harvest needs

The Pro-Drive Modular series

Pro-Drive 85MH (AS) hydro motor

For hydro motor powered knives
Pro-Drive 85MH (AS)

This knife drive connects to a hydraulic system. Adapters are available in various sizes to connect to the hydro motor’s output shaft. This drive is typically used on headers with variable tables or variable speed cutter bars.

Pro-Drive 85MH (AS) cardan shaft

For cardan shaft powered drives
Pro-Drive 85MH (AS)

This flange-mounted drive was developed for headers and machines that have a cardan shaft to drive the cutter bar. The unit is also available with a regular 1 3/8 inch, six-spline pto shaft as an option. This drive is the unit of choice for headers with variable tables.

Pro-Drive 85MH (AS) belt drive

For belt driven knives
Pro-Drive 85MH (RS)

This drive transmits the power to the cutting system via a horizontal pulley. The working diameter of the pulley is customized ex factory. Typically used on standard headers.

Pro-Drive 85MV (AS) belt drive

For belt driven knives
Pro-Drive 85MV (RS)

This drive transmits the power to the cutting system via a vertical pulley which eliminates a change in direction of the power flow. Multiple variants available ex factory. This versatile drive that is used in a variety of header types.

Pro-Drive Economy series

Pro-Drive 85EH (RS) belt drive

For belt driven knives
Pro-Drive 80EH (RS)

This compact and light-weight drive unit has a horizontal pulley for direct power transmission to the cutting system. It is particularly suitable for small-width canola and sunflower headers.

Pro-Drive 80EV (RS) belt drive

For belt driven knives
Pro-Drive 80EV (RS)

This compact and light-weight drive unit has a vertical pulley and an integral angular gearbox which eliminates a change in direction of the power flow. Multiple variants available ex factory.

Standard pulleys

Standard pulleys

Standard pulleys

A large range of pulleys is available in different sizes (7-9 inch diameters) and specifications for the Pro-Drive 85MV (RS) and Pro-Drive 80EV (RS) knife drives. All pulleys have the SPC profile (DIN 7753) as standard. Further pulleys for belt pairs and poly belts are available on request.
