3. Preparation & Set Up The following statements apply to the full range of Sumo cultivators. For an overview of your specific machine, see associated Machine Manual and Parts Book in conjunction with these instructions. 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.

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.
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.
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.
Page 22
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.
& loading. Due to the length and design of many Sumo machines, the transportation wheels are often to the rearmost of the machine meaning it will cut corners. Care must be taken to ensure a wide swing and reasonable turning arc is maintained to avoid any fouling of other vehicles or road markings/obstacles.
It is the sole responsibility of the operator to ensure they comply with all local road laws and Sumo accepts no liability for negligence or carelessness.
Page 25
Fixed Stands Fixed Stands generally consist of a welded bracket, a bolted joint and a pin, offering two positions: In Work and Retracted. Simply remove pin, rotate the bracket until in retracted or in work position and re-insert pin. Pins must always be secured with an additional lynch pin.
Page 26
Adjustable Jack Stands: Adjustable jack stands generally consist of winding or lever systems allowing for a much slower and measured movement, whilst also providing greater support, or assistance with hitching/unhitching. To position an adjustable jack stand, support stand with one hand and pinch the two clasp levers together with your other hand until clear of holes, then lower slowly pivot and lower the unit down until in next set of holes.
Crank Lever Release Winding Handle Catch 4.3.3 Pneumatic Brakes Pneumatic brakes generally consist of two brake cylinders (one per wheel), a pressurised air tank, a set of configured brake levers (Both usually located at the rear of the machine closest the axle/wheels), and an REV (Typically located near the front of the machine).
4.3.4 Hydraulic Brakes Hydraulic brakes generally consist of two hydraulic cylinders attached directly to the axle brake levers, typically located at the rear of the machine/mid- machine axle. For connection details, see Hitching and tractor connections section of this manual. Example: 28 | P a g e...
5. 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.
Accumulators Sumo hydraulic systems use high pressure accumulators, which can present a danger if tampered with or misused. This includes drilling, welding or any other process that could compromise the safety of the accumulator. It is expressly forbidden for an operator, or any third party to dismantle or adjust the accumulator in any way.
This will set the working depth for any related elements. The machine should then be levelled/limited through the use of the cylinder shim holder, see Shim holders’ section. For trailed machines, the retractable wheel axle can now be retracted. 5.2.2 Leg Depth It is advised that the soil is assessed prior to working to determine the level of compaction within the soil profile and the depth this compaction is at.
5.2.3 Shear Pin (SP) Shear pins only need adjusting once the shear pin has sheared off. Simply remove the retention clip, correct the angle of the Retention leg and advance the shear pin through legs oblong hole to the Clip next stage, re-insert retention clip.
Even though the pressure is locked in the circuit, this system does remain active in that the legs can be raised up out of work. The tractor hydraulics should be returned to float to relieve any back pressure before commencing work at the new pressure Note: It is advised that on a machine fitted with auto reset legs the double acting feature is used in road transport to retract the legs and reduce the overall width...
5.2.6 Paddles Paddle arrangements operate using a simply tilt mechanism linked to a sequence hydraulic cylinders. To lower or raise, simply adjust the hydraulic pressure, hydraulic connections section of this manual. 5.2.7 Scrapers Scrapers come in an assortment of brackets and profiles, depending on the packer type &...
5.2.9 Depth Wheel Depth wheels come in a variety of different forms, but generally work either on a simple pin or top link system. For Pin Systems, simply remove the pin, raise and lower the depth wheel to the desire specification and reinsert the pin.
& Parts Book. For any parts not covered in these documents, contact Sumo directly, as they may be relevant to a set period of manufacture. Sumo do not sanction the use of any products/parts not produced and managed by Sumo. Using external products will invalidate your warranty.
Some Sumo parts are intended to be wearable due to the nature of their design and use. For best results, check routinely and replace as required. This will help prevent loss/destruction of implements during work.
Storage It is generally advised to store Sumo machines in their folded positions to minimise the exposure of unpainted rams, and lessen the impact on tools/wearable components. Follow all parking guidance given within this manual. Wherever possible, try to find a sheltered environment.
