Summary
The SUMO Deep Tillage Seeder (DTS) drill is based on a concept known as ‘strip till drilling’, a method
of only loosening and preparing a band of soil where the seed is to be placed and leaving the soil in-
between rows undisturbed, and therefore not working ground unnecessarily.
The DTS, a uniquely versatile drill capable of direct drilling, min-till drilling and conventional plough
based drilling. Designed and manufactured in Britain, the DTS features an auger (Sumo patent name
“Orga”) metering unit capable of dispensing wide range of seeds and fertilisers and widely varying rates.
DTS features:
•Based on 33.3cm row spacing.
•Individually mounted seeding units that articulate with ground contours and are governed by a
constant flow pressured hydraulic system.
•Leading opener disc for cutting through trash
•Single tungsten edged deep loosening auto-reset leg capable of a maximum working depth of
250mm
•Wide band (approx. 150mm) or narrow (approx. 25mm) row seed opener boots place seed in the
loosened strip
•Covering discs channel loosened soil over the seed
•Gel filled press wheels firm the soil around the seed and also govern the sowing depth of the
coulters
Before using the Sumo DTS it is absolutely necessary that you read this Operators manual and Safety
Instructions attentively.
Specifications, descriptions and illustrations in this manual are accurate, as known, at the time of
publication but may be subject to change.

When removing pipes from the tractor make sure all hydraulics are fully open or fully closed before
applying float on the tractor.
The wings are fitted with check valves on the rams which allows them to be depressurised without
letting the wings unfold.
The changeover tap for the wings and bout markers (4m, 4.8m and 6m versions only) is located on the
front of the chassis beneath the hopper access steps.
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 reduce the restrictions in the
free-flow line, usually at the point where it enters the tractor.

2.0 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 accessible 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 any warranty claims becoming invalid.
2.1 Qualification and Training
Reliable personnel only may 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.

12
2.2 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.
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 length, the wide overhang, the folded height and the sideways force acting
on the machine when turning or negotiating curves.
2.3 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 SUMO machine unless the tractor is
secured against rolling away by means of parking brake and/or wheel chocks.
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.
Ensure all persons are stood clear of the machine when folding or unfolding.
When making adjustments to the machine the tractor engine should be switched off to prevent the
hydraulics from operating.
When making adjustments to the machines care should be taken not to trap any body parts in
moving or pivoting parts.
When working on the coulters, extra consideration should be placed on the safety of personnel.
Ideally the DTS should be folded up with the wings positioned in their transport support carriers.
If this is not possible and there is no other way than to work beneath the coulters then the DTS
must be reversed up to a suitably strong wall to protect against crushing in the unlikely event that
the hydraulics should fail. Also the front end should be hitched up to a tractor, with the parking
brake applied on the tractor.

3.2 Main functions
The Artemis is designed to allow automatic, variable rate control of any drill. You can at any time,
also manually override the predetermined rate as field conditions require.
The basic functions are:
Variable Rate Control
Tramline Control
Forward Speed Alarms
Hopper Level alarm
Fan Speed & alarm
Information totals
The instrument has a special software routine that makes calibration of the metering unit(s) very easy. In
the calibration mode each metering unit is controlled via a ‘priming switch’ to dispense the product.
During normal operation the control system is started and stopped automatically via a magnetic sensor as
the drill is put into and taken out of work. Depending on the particular installation, this sensor is
triggered either by the operation of the lift/lower action or by the markers.

15
3.3 Control Modes and Data Logging
Automatic Control Mode
The application rate is automatically regulated as forward speed varies, to ensure that the actual
application rate constantly matches a preset target rate. The application rate can be manually
nudged up and down from the target rate as required.
Field data ("job summaries") can be logged and are stored in the instrument memory. Up to 75
summaries can be stored. With a GPS receiver and SD data card, as well as creating a job
summary, you can also log the vehicle route and application data to a "dynamic log" file on the
SD card. The job summary data is also appended to this file.
VRT (Variable-rate treatment) Control Mode
This enables the system to be controlled via treatment instructions prepared using Precision
Farming software in conjunction with DGPS position data. To enable fully automatic variable-rate
treatment for Precision Farming applications, the PS 8000i requires a suitable DGPS receiver and
a formatted SD data card to implement treatment plans generated in the Precision Farming
software.
A work record file is automatically created on the card to log data confirming the actual treatment.
The job summary data is also appended to this file, which can be viewed in the Precision Farming
software
3.4 Menu keys
All instrument functions are accessed by nine menu keys adjacent to the LCD display.
Figure 2. Artemis control box
The four menu keys to the right of the screen access the primary screen pages (those viewed
during normal operation). There are three primary screens MAIN, RATE and INFO for normal
operating functions, and a SETUP screen for calibration functions.
The five sub-menu keys below the screen control the various display functions and settings for
each of the primary screen pages. Text or icons are displayed adjacent to the sub-menu keys to
