Connect the hydraulic hoses to the tractor spools in their relevant pairs. The 1” ISO female coupling with
18L male thread supplied with your drill MUST be connected to the tractor rear axle. If necessary, your
tractor dealer will advise. The return pipe cannot just be inserted into the filler cap as the oil cannot
return to the pump sufficiently quickly in many tractors. DO NOT CHANGE THE 1” ISO TO A DIFFERENT
SIZE AS THIS COULD CAUSE DAMAGE TO THE FAN MOTOR,WHICH IS NOT COVERED BY WARRANTY. The
fan return cannot be connected to the tractor ISO.
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..
