Operation
Note: Determine the left and right sides of the machine
from the normal operating position.
Controls
The controls are conveniently located on control tower at
front of frame. To raise mower(s), push control lever(s) up,
to lower mower(s) push control lever(s) down. Hold
lever(s) in their respective positions until cycle is
completed, then lever(s) will return to neutral. To partially
raise or lower mower(s), partially actuate control lever(s) to
move mowers as desired.
The transport frame is equipped with an open center
hydraulic system, and designed for use with tractor using
same system. Special precautions must be taken if tractor is
not an open center hydraulic system. Determine which
system is on tractor and use the following operating
procedures:
1. Open center hydraulic system on tractor and open
center hydraulic system on transport frame.
• Connect supply/return hoses to tractor valve
couplers. Make sure high pressure line is connected
to inlet port on frame valve.
• Restrain tractor hydraulic directional control valve
lever to allow a continual flow of fluid to the
transport frame valve.
• Start tractor and raise or lower mowers using control
levers.
Note: If mowers will not raise or lower, supply/ return
hoses may be reversed. Reinstall couplers reversing
position. Mark hoses for future identification or connect a
male and female coupler section to transport hoses to
prevent reversal.
Important After disconnecting supply/return hose
couplers from tractor valve always return tractor
hydraulic directional control valve lever to neutral, to
deactivate ”remote” hydraulic feature.
2. Closed center hydraulic system on tractor and open
center hydraulic system on transport frame.
Note: A closed center conversion kit is available from your
local Toro Distributor and is recommended for use with this
type of system. If kit is not used, follow these procedures
for operation.
• Connect supply/return hoses to tractor valve
couplers.
• Start tractor.
• Tractor hydraulic directional control lever must be
actuated simultaneously with control levers on
transport frame. Do not restrain tractor valve lever
permanently, damage may occur to system.
• Raise or lower mowers using control levers.
Note: If mowers will not raise or lower, supply/ return
hoses may be reversed. Reinstall couplers reversing
position. Mark hoses for future identification, or connect a
male and female coupler section to transport hoses to
prevent reversal.
3. Closed center hydraulic system on tractor and
closed center conversion kit mounted to transport
frame valve.
• Connect supply/return hoses from frame valve to
tractor valve couplers.
• Restrain tractor hydraulic directional control valve
lever to allow continual pressure at frame valve.
Note: When transporting frame, return tractor control valve
lever to neutral because the cylinders may gradually extend
causing lift arms to lower.
• Start tractor and raise or lower mower using control
levers.
Note: If mowers will not raise or lower, supply/ return
hoses may be reversed. Reinstall couplers reversing
position. Mark hoses for future identification, or connect a
male and female coupler section to transport hose to
prevent reversal.
Important After disconnecting supply/return hose
couplers from tractor valve, always return tractor
hydraulic directional control valve to neutral.
4. Open center hydraulic system on tractor and closed
center conversion kit mounted to transport frame
valve.
• NEVER use this combination.
Training Operation
Before mowing for the first time, practice operating your
Tractor and Transport Frame in a large, clear, level area.
Start, stop, raise and lower mowers and maneuver the
machine with all mowers down to develop skills necessary
to keep control of the extreme outboard mowers to prevent
hitting obstacles. Also, practice operating at transport
speeds with mowers in transport position to achieve
familiarity with all types of operating conditions.
