Hydraulic Brake Connections
Hydraulic Brake hose connections are not colour coded, however the connection
socket is shaped so that it cannot be mistaken or interchanged with any other
connection. Ensure hose is depressurised before coupling/uncoupling.

Mounted Machines
Due to the physical nature and weight distribution of some Sumo machines a
category three enclosed ball top link is highly recommended. Due to the
exaggerated loads experienced during normal working conditions, the top link
pin is considered as a consumable part and should be checked for wear on a
regular basis.
When hitching the Sumo machines three-point linkage to the tractor, ensure the
linkage arms are correctly angled so that the lower arm is horizontal and top
arm
linkage is diagonally aligned with the tractor’s front axle. This will ensure a
strong, stable weight distribution and connection. Top & Bottom linkage arms
should never be parallel. Having them parallel will reduce the tractors drive
wheel grip and may cause damage to both the tractor and the linkages.
Steps:
•
Attach lower linkage points first, then attach the top linkage, ensuring a
permanent and secure fix.
•
Turn tractor off, float hydraulic systems, then safely connect hydraulic &
electric connections.
•
Lift machine just enough to clear the ground of any parking
feature/working instruments.
•
Remove parking features/position them in the transport/working
positions.
•
Perform all necessary tests as outline within this manual.
•
Turn tractor back on.
3.2.2
Trailed Machines
Trailed machines come in two variants, rigid & hydraulic drawbar, depending on
the design. Both follow the same hitching process, although hydraulic drawbars
can be positioned to better suit the tractor hitch point, if necessary.
