Subject:
Information to aid in correct fit and function of the HD Workman equipped with the
Cushman Core Harvester attachment.
Situation:
Prior to 2004, the Cushman Core Harvester was powered by the Workman Remote
Hydraulics system which is a 4 gpm circuit. The core harvester requires a 6 gpm hydraulic
power source. To compensate for this difference, Toro specified a smaller displacement
motor (92-4240) for the elevator conveyer on the core harvester. This motor was part of
Mount Kit (44242) that adapts the core harvester to the Workman application. In 2004, we
elected to eliminate the motor from the mount kit and power the system with the 8 gpm
High Flow Hydraulics circuit. This eliminated the need for the small displacement motor.
However, when running the 4 gpm system, operators had learned to run the engine at full
rpm to provide required performance from the core harvester. This operating practice
changed when the 8 gpm system was implemented due to the additional flow supplied by
the 8 gpm system. Operator re-education was required. Further confusion was
experienced when trying to mount an older core harvester on a newer Workman or the
opposite.
Correction:
A reference matrix was built to instruct on the required set-up and operating parameters,
dependent on the vintage of the vehicle and attachment involved. This matrix appears
below. When using High Flow Hydraulics, it is important to allow the vehicle engine to slow
to low idle prior to switching the hydraulic system off. This will avoid failed seals in the
system due to inertia developed by the conveyer motor.
Please contact your local Toro Commercial Products Distributor for additional information
and assistance on this issue; reference Service Bulletin Vehicles 17-19 “Cushman Core
