Operation & Adjustment
Before using any Sumo machine, you must ensure you are qualified and trained to use the
machine in the safest possible manner. Familiarise yourself with both the machine and this
manual and follow its instructions. Sumo will accept no liability for any persons
trained/untrained using the machine inappropriately.
The material within this section is correct, as known at the time of publication, but may be
subject to change. If in doubt, ask your local dealership/Sumo representative.
5.1
Operations
Before Start
Ensure machine is correctly hitched as described in the Hitching section of this manual,
and ensure all securing mechanisms such as dog bones and/or wing locks are fully
detached/disengaged.
5.1.1
Straights
Lower working implements into the ground and accelerate slowly to ensure the
machine does not endure any immediate jolts of pressure. This will help extend
the life of the product and reduce any damage/wear to wearing parts.
Adjust hydraulic systems gradually and do not overburden the system with
constant heavy/excessive pressure. This may damage the system and
instruments. Some machine elements such as Tines are designed to be flexible
and absorb moderate amounts of strain, but excessive/ prolonged amounts
may cause them to snap, so always be gentle but assertive with the machinery.
Advisable speed for any Sumo cultivator is 5 mph/8 km.
5.1.2
Turning
Depending on the machine purchased, some Sumo machines can have large
turning circles. Ensure there is enough of a berth before initiating any turn.
Raise all implements fully out of the ground. Move slowly so the weight of the
machine does not shunt drastically over to one side and topple the tractor.
Avoid turning on any slopes or unstable ground.
When turning on headlands the machine should be lifted clear of the ground
and can be run on just the packer to prevent excessive compaction of headlands
rather than running on the wheels.
