the flange is pointing horizontal, the valve is open (calibration position). Ensure this is closed before
commencing seeding.
Sumo Orga Metering:
Sumo’s versatile metering unit. The metering unit is designed so that it can meter
any granular products at any reasonable rate and drilling speeds with only simple setting changes. The
Sumo ORGA Metering Unit does not use traditional rollers. There are two metering units, one for each
hopper. When the hopper is setup as a single large capacity, only one metering unit is necessary. The
second redundant metering unit can be shut off using the hopper slide inserted above the metering unit.
6m DTS’s and over also have the half width shut-off (HWSO) facility. This adds a further Orga metering
unit to each product hopper, so there will be four units in total.
Fan balancing Valves:
The seed/fert transfer Pipes are fitted with fan balancing valves so that
adjustment can be made to the velocity of the air travelling through each pipe. This may be necessary
when there is a large difference in rates between each metering unit. For example there may be a situation
when you are drilling 120kg/ha of seed and 340kg/ha of fertiliser, the percentage air velocity on the seed
side would need to be less to cater for the difference in seed/fert rates. This can be achieved by adjusting
the air valve on the seed pipe by moving the lever towards the rear of the machine (reducing air velocity).
Where possible the valves should be left fully open, only reduce the air velocity on the pipe metering the
smaller rate. Where rates are equal the valves should both remain fully open.
Fan/Coulter Pressure Gauges:
Indicators of Hydraulic Pressures in Fan/Coulter Systems.
Large Capacity Toolboxes:
Watertight large capacity toolboxes for storing tools, spare parts, seed boots,
calibration bag etc. The top toolbox also houses the RDS electronics to protect them from water and other
damage.
