Reservoir Capacity 18.2L
Total System Capacity 25.7L
To check the hydraulic fluid level on units that DO
NOT have the electronic Turf Protection System
(leak detector), locate the sight glass on the tower
portion of the reservoir. Visually inspect to see if
there is 1/2” (13mm) (at ambient temperature) of oil
visible above the lower portion of the sight glass. If
not, unscrew the reservoir cap and fill to proper
level (See Fig 33).

Hydraulic Oil
The hydraulic fluid reservoir is filled at the factory
with Shell Harvella
Determination of the proper mineral oil hydraulic
fluid for your application will require selection of a
set of conditions that best matches your particular
situation. It is recommended that you then use that
type of fluid year round rather than changing fluid
types on a seasonal basis.
32/46 Multi-Viscosity Fluid
The 32/46 multi-viscosity type fluids allow normal
operation at lower ambient temperatures with less
increase in viscosity. These fluids are
recommended for operating temperature
environment consistently below 90°F (32°C).

All of the above fluids are interchangeable within the
32/46 multi-viscosity group.
Use of the 32/46 multi-viscosity type fluids in the
higher temperature environment may produce lower
efficiency in some of the hydraulic components as
compared to the ISO 46 straight-viscosity type
fluids.
ISO 46 Straight-Viscosity Fluid
When using the straight-viscosity ISO 46 fluid in a
lower temperature environment, conditions of
increased engine laboring, harder starting or
inconsistent control valve spool operation may occur
until the fluid has warmed.
The ISO 46 straight-viscosity type fluids will
maintain a slightly higher viscosity at higher
temperatures than the 32/46 multi-viscosity fluids.
These fluids are recommended for operating
temperature environment consistently above 70°F
(21°C).
