can lower slowly and unnoticed.
-It is expressly Forbidden for anyone to ride on our machines at any time.
-Never stand under the machine or lifted loads. Lower to the ground first.
-Machines should never be parked, folded or unfolded, or accessed in the
presence of overhead power lines or pylons to ensure no flashover is possible.
Special care should also be taken when manoeuvring nearby, folding or
unfolding to ensure no contact is made.
-Instruct persons to leave the danger zone around the machine and tractor.
-Before working in the danger zone of the machine or between machine and
tractor: Shut down the tractor! This also applies for short-term inspection work.
Many accidents happen because of carelessness and running machines!
-Accidental operation of the hydraulic system can trigger dangerous movements
of the machine.

8 | P a g e
-Failing to pay attention to the danger zone can result in severe or even fatal
physical injuries.
-Check around the machine before moving off or starting up (Watch out for
children or animals!). Make sure you have adequate all-round visibility.
-Always match your speed to the local conditions. Avoid any sudden acceleration
or turning manoeuvres when driving uphill or downhill or when travelling across
a slope.
-Consider the length, the wide overhang, the folded height and the sideways force
acting on the machine when turning or negotiating curves.
-Ensure all transportation guidelines are followed within this manual.
-Ensure Sumo machines are only used for their intended use as outlined in this
manual.
Young persons are less able to react to danger and are unlikely to have enough
experience to react to situations and therefore should be kept well clear of the operating
zone of the machine. Children should Not be left in/on the tractor/machine even when
the machine has been shut down as hydraulics can still be operated if they are a
mechanical spool. The minimum age of children riding on agricultural equipment locally
in the country of operation must be adhered to. Sumo does not permit Anyone to ride
its machines at any point, trained or untrained.
1.3 Personal Protective Equipment (PPE)
To protect the user and persons surrounding the machine during
operation/maintenance suitable PPE must be worn:
-Tight fitting clothes or overalls, ensuring no loose clothing is able to get caught
in the machine while it is in operation, this includes long hair, which should be
tied up or placed in a hair net.
-Suitable footwear, steel toe capped shoes/boots, especially during the lowering,
detachment or adjustment of any machine/feature.
-Eye protection such as safety glasses or goggles during general usage and
especially when changing wearing components as these may be under pressure
and can release suddenly, and when working with hydraulic components as the
pressure may not have been released properly and could release suddenly.
-Jewellery such as rings, necklaces, bracelets and watches should not be worn
while operating/maintaining this machine as it can get caught and cause further
injury.
-Suitable hand protection, specifically during adjustment, maintenance, and when
attaching the machine to a tractor as hydraulic oil can cause injury if it is under
pressure as it can pierce the skin and cause serious health problems if it enters
the blood stream.
As a general rule, Sumo advise all PPE to be worn at all times, just to be safe.

3. Preparation & Set Up
The following statements apply to the full range of Sumo drills. For an overview of your
specific machine, see associated Machine Manual and Parts Book in conjunction with these
instructions.
3.1 Pre-Check & System Overview
Before performing any other action on a Sumo machine, always check the following:
-Check the machine for worn or loose parts, mechanical and structural integrity,
hydraulic leaks, exposed or corroded wires, warning label cleanliness and clarity.
-Maintenance programme carried out in line with schedule.
Faulty equipment can lead to damage to the machine or injury to persons. Always be
diligent and ensure the machine is in perfect condition before use.
3.2 Hitching & Tractor Connection
Faulty hitching up of the machine to the tractor causes dangers, which could result in
severe accidents. Hitching and unhitching of the machine should only take place on a
secure and level surface with chocks placed under the wheels of trailed machines to
prevent the machine from rolling away.
General Safety
Familiarise yourself with the machine and all safety guidelines/regulations given in this
manual, industrial standards, and safe work practices, before attempting any hitching
of Sumo Machines.
Never allow anyone to stand between the tractor and the Sumo machine whilst the
tractor is manoeuvring into position. Only once the tractor is in position and secured
against rolling away, by means of parking brake and/or wheel chocks, can the
operator/third party secure the machine to the tractor.
Ensure the wings are either in the fully up ‘transport’ position or fully down in the “work”
position before uncoupling from the tractor. The machine should always remain secured
to the tractor when the wings are anywhere between fully up and fully down.
Always ensure tractor hydraulics are depressurised before attempting hydraulic
connection.
Types of Hitch
Sumo machines come with a variety of hitch types; fixed, adjustable, bolted. The tractor’s
hitch must be suited/adapted to match the machines requirements.
Fixed hitches generally refer to either a fixed position drawbar for trailed machines, or
three-point linkage for mounted machines.

17 | P a g e
Adjustable hitches are single point connections that allow the hitch height to be adjusted
to suit tractor requirements.
Bolted hitches generally refer to an external supplied, pre-rated and approved hitches
which can be purchased separately or selected during the consultancy period (Note:
These may not be available on all machines). For more information contact your local
dealership or Sumo representative directly.
Fixed (1) Fixed (3) Adjustable Bolted
Standard Hydraulic Connections –Colour Code
Sumo’s colour coding is done through a
sequence of cable ties attached to the
individual hydraulic hoses, as seen in
this picture. Before connection, ensure
all connections are cleaned to reduce
the risk of contamination.
One cable tie = Return
Two cable ties = Pressure
Yellow
Orange
Blue
Red
Free-Flow Return
Damage will occur to either the fan motor seal or the oil cooler (oil coolers are only
fitted to seed & fertilizer machines) if the free-flow return hydraulic line is not
connected to the tractor first. Any movement of the fan or the coulters immediately
pressurizes the free-flow return line. This includes just lowering the machine to the
floor to allow the coulters to “take some weight”. Doing this will displace oil from the
coulter rams and pressurize the free-flow line, which may result in component
damage. When connecting the free-flow line it is necessary to observe the back-
pressure present. A gauge for this reason is provided, mounted on the fan. The
maximum return pressure is 15bar. Running with a pressure higher than this will
result in damage, so it is then necessary to take steps to relieve pressure in the free-
flow line. This is done by coupling it to the tractor via the QRC.

Air Brake Connections
The air brake hoses are colour coded as follows:
Yellow
Red
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.
3.2.1 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.

19 | P a g e
3.2.2 Trailed Machines
DD & DTS Trailed machines only come with a rigid design. Therefore, all
manipulation of the machine height and parallelism is done via the axle and
tractor positions.
Steps:
•Slowly back tractor up to machine.
•Release pick up hitch in a low position, extend outwards if required.
•Reverse carefully up to hitch and locate hitch onto machine towing eye.
•Retract hitch if it has been extended.
•Raise hitch until locking pin is secured.
•Lower three-point linkage to release upward pressure on pick up hitch.
•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.
3.3 Electronics Connection & Testing
Plug all electronic equipment in. Walk around the machine and ensure all lights are
functional. Visually inspect wiring looms for any exposed wires, breakages or damage.
If the system shows any sign of issue, see the troubleshooting section of this manual.
If you have any additional Sumo electronic equipment, see the Optional
Extras/Attachments section in this manual.
3.4 Hydraulics Testing
Check general hoses condition, abrasion, kinks etc. Visually inspect for leaks or
damaged connections. Do not touch with hands or get close enough to inhale any
vapours. Check cylinder condition and cleanliness. Run each system individually i.e.
wings up and down, drawbar up and down. If the system shows any sign of issue, see
the troubleshooting section of this manual.
3.5 Uncoupling of Tractor
Never uncouple on an uneven or unstable surface. Ensure both the tractor and the
Sumo machines are on level, solid ground and put them in a secured configuration,
by use of handbrakes, chocks and any other movement prevention systems available.

20 | P a g e
Tractor must be fully immobilized with the key removed from the ignition. Obey all
other relevant safety practices outlined within this manual, including but not exclusive
to, the machine in general, hydraulics and electrics, and environmental awareness.
Locate machine on the provided stands, or parking elements (see parking section of
this manual), Depressurise all hydraulics before disconnection, and ensure all electrics
are detached and safely tied back. Only once the machine is fully stabilised and clear
of the tractor linkage should the tractor be driven slowly away, remaining vigilant to
not drag or knock the machine.
