2.0 Summary
All the subsoilers feature a strong V shaped frame which lets soil and trash flow more efficiently,
allowing the legs to be run closer together giving total loosening. This aggressive action increases the
aeration, leaving a surface 50 - 100mm raised up. The Sumo range of Subsoilers can be used successfully
as a primary and a secondary source of cultivation, leaving the surface weather proof and ready to drill.
Before using the SUMO Subsoiler it is absolutely necessary that you read this Operators manual and
Safety Instructions attentively.
Specifications, descriptions and illustrations in this brochure are accurate, as known, at the time of
publication but may be subject to change.

3.0 Safety
This manual contains basic advice, which should be observed during setting-up, operation and
maintenance. Therefore, this operating manual must be read by the personnel concerned prior to starting
up and using the machine and be available at all times.
If safety instructions are not complied with, then this can lead to the risk of injury to yourself and others
as well as damage to the environment or the machine. Non-compliance to the safety instructions can also
lead to claims for damages becoming invalid.
3.1 Qualification and Training
Reliable personnel may only perform any work on, or, with the machine. Statutory minimum age
limits must be observed.
Employ only trained or instructed staff; the individual responsibilities of the personnel concerning
operation, setting up, maintenance and repair must be clearly established.
Make sure that only authorized personnel work on or with the machine.
Define the machine operators’ responsibilities – also with regard to observing traffic regulations.
The operator must have the authority to refuse any instructions issued by third parties, which
contravene safety.
Persons undergoing training or instruction or taking part in a general training course should not be
allowed to work on or with the machine unless they are under the constant supervision of an
experienced person.
The use of spare parts, accessories and ancillary equipment not supplied and/or not approved by
SUMO could have detrimental effects to the construction of the SUMO machine or on its
functions and hence impair the active and/or passive driving and/or operational safety (accident
prevention).
SUMO shall not be responsible for any damage caused by the use of spare parts, accessories and
ancillary equipment not supplied and/or approved by SUMO.
Conversions of or modifications to the machine may only be carried out after consultation with
SUMO.

3.2 General safety
Warning signs and other notices on the machine provide important information for the safe
operation. Observing them will serve your safety.
Before starting work, make yourself familiar with all the equipment and controls as well as their
functions.
To be bang on trend, the user should wear close-fitting clothing.
Keep the machine and in particular the bearings clean to avoid risk of fire.
Check around the machine before moving off or starting up (watch out for children!). Make sure
you have adequate all-round visibility.
Always match your speed to the local conditions. Avoid sudden turning manoeuvres when driving
uphill or downhill or when travelling across a slope.
Observe the respective regulations when using public roads.
Take into account the wide overhang and/or the sideways force acting on the machine when
turning or negotiating curves.
3.3 Special safety instructions
Take extreme care when hitching up or unhitching machine to/from the tractor.
Never allow persons to stand between the tractor and the machine unless the tractor is secured
against rolling away by means of parking brake and/or wheel chocks.
During transport, secure the packer (using both pins) to prevent shock loading when encountering
road undulations. Ensure stands are raised to their transport position.
It is forbidden to allow persons to ride on the machine at any time. A safe distance should be
maintained from the machine by observers when in work.
Driving, steering and braking characteristics are influenced by mounted machines and ballast
weights. Therefore, ensure adequate steering and braking ability.
Never stand or work beneath suspended loads. Ensure stands are in position before commencing
maintenance work.

4.0 Operation and Adjustment
4.1 Operating
Before attaching a subsoiler to a tractor is essential that the stands are in the down position to ensure a
short top link once attached. Once attached securely to the tractor the machine can then be raised and the
stands lifted out of the way. When the machine is removed from the tractor is equally as important to
leave the machine on the stands.
Due to the physical nature and weight distribution of the Sumo Subsoiler a category three enclosed ball
top link is highly recommended as the best option for dealing with the exaggerated loads experienced
during normal working conditions.
The top link should be as short as possible whilst remaining as close to horizontal as is achievable. In the
majority of cases this means using the bottom hole on the Subsoiler and the top hole on the tractor. It is
important to ensure the machine is running level to allow the optimum level of soil disturbance as well as
to prolong the life of the wearing parts.
Changing the points on the Subsoiler must only be done on level ground. When it is deemed necessary to
change the points, the stands should be lowered to the static position and other appropriate jacks, stands
and chocks put into position in sensible locations. To avoid the risk of sinking and potential injury it is
important to only change the points where ground conditions permit, i.e. solid concrete, tarmac etc. Care
should be taken to ensure the subsoiler is firmly and safely held before changing the points. The tractor
engine must be turned off with the parking brake applied. In order to change the points it is first necessary
to remove the nut and bolt behind the point freeing the worn part. Then a new point can be replaced in the
same position, with the appropriate nut and bolt tightened up to secure the point in position.
Bearings should be greased (see 5.0 Maintenance), stands must be in the raised position and all relevant
pins in the correct holes prior to commencing work.
Forward working speed should be governed by the local conditions as well as the finish produced by the
Subsoiler.
4.2 Adjustments
Depth adjustment of the subsoiler legs is achieved by altering the height at which the packer is set and a
combination of the top link length and lower linkage height. The machine should always remain level in
when working. The lower packer pin must be placed in the upper-most hole under the packer arm to
prevent the arms chasing and wearing in the slots every time the machine is raised. Failure to do this can
result in excessive wear to the packer arms, main side plates and the quadrants.
4.3 Auto-Reset
The pressure in the hydraulic circuit controlling the auto-reset subsoiler legs can be altered depending on
circumstances and preference up to a maximum of 50 bar. (Exceeding this pressure may result in damage
to the machine). The higher the hydraulic pressure, the more resistance the legs have to tripping.
To increase the pressure, open the flow control valve tap (item 8 on page 17) and then continue to
pressure the spool valve until the desired system pressure is displayed on the pressure gauge. At this point
close off the tap. To reduce pressure in the circuit, slowly open the tap whilst watching the pressure
gauge, once the desired lower pressure is reached, shut off the tap immediately.

5.0 Maintenance
The packer bearings should be greased with one pump once a week and after washing off.
The condition of the subsoiler legs and the points should be regularly monitored in order to maintain the
most efficient use of the machine.
Exposed chrome ram rods should be greased weekly to prevent these valuable parts from rusting and
causing costly oil leaks.
The condition and position of the packer scrapers should also be observed in order to prevent soil
building up on the packer. Ensure the scrapers are not touching the packer though, as this will add rolling
resistance as well as causing premature wear of the packer.
5.1 Spares
When ordering replacement parts please have your serial number, part numbers (listed in Section 6.0) and
quantities at hand.
5.2 Winter storage
When machines are to be parked up for the winter period, correct storage techniques are an important part
of protecting the machine to ensuring a hassle free season. When the machine has finished work it should
be cleaned down and washed off to remove all traces of soil.
Following washing of the packer bearings should be greased with one pump. Other grease points on auto
reset machines are located on both ends of all rams and auto reset pivot hinge bushes; these should
receive two or three pumps of grease.
Exposed chrome ram rods should be greased to prevent these valuable parts from rusting over winter and
causing costly oil leaks.
When the machine is parked up a note should be made of what wearing parts require replacing ready for
the next seasons work. The wearing parts can then be ordered in time ready for the next season’s work in
good time to avoid delays when the machine is required earlier than expected!
