Gearbox
The gearbox fitted to the MERCURY COVAMAX has two speeds,
•
Position 1 - Slow speed 540/1890RPM (1:3.5 Ratio)
•
Position 2 - Neutral (disengaged drive)
•
Position 3 - Fast speed 540/2380RPM (1:4.4 Ratio)
±
Warning: Make sure that PTO shaft has come to a complete stop before changing gears on gearbox
÷
Note: If the gearbox will not engage it is most likely that
the gear teeth are clashing. Move the gearbox lever to the
off (neutral) position and turn over the PTO, when PTO has
come to a stop attempt to engage gearbox again.
Blower Unit, Distribution Stack & Outlet Spouts
The HF600 blower unit takes its drive from the gearbox output to turn the blower wheel. Air is drawn in from the
rear of the blower and forced up through the distribution stack. Airflow is then carried through the boom tubes to
the outlet spouts where it blends with the spray solution from the spray nozzles.
Airflow quantity is controlled by the gearbox setting which determines the fan speed.
