Grouper Canvas Drive

To meet all tractor hydraulic system requirements, two grouper canvas drive configurations are available:

Self-contained Hydraulic Circuit:

In this configuration, the grouper is driven by a belt which makes the hydraulic canvas motor shift the windrow towards the left-hand side.

NOTE: This configuration avoids all risk of grouper oil becoming contaminated by oil from the tractor.

Direct Drive Hydraulic Circuit:

In this configuration, the grouper is directly driven by the tractor hydraulic system via one double-acting selective control valve, which makes the hydraulic canvas motor shift the windrow towards the left-hand side.

IMPORTANT: When using a 30, 40, 50 or 55 Series tractor with air conditioned cab, a second oil cooler is required to avoid oil overheating when driving the grouper's hydraulic motor.

NOTE: This configuration is particularly suitable for using the grouper with John Deere tractors. A 6000 or 7000 Series tractor must be equipped with a 200 or 300 Series selective control valve to drive the grouper's hydraulic motor.

A 3000 Series tractor must be equipped with a double-acting (3-position) selective control valve to drive the grouper's hydraulic motor.
