Moore Unidrill-W Series, Owner'S Manual

Page: 19 / 46

SETTING 1
Spring loaded flaps one below each fluted metering roller allow the sowing of
a wide range of seed sizes, with a single adjustment to positively control the
flow of small to large seeds past the rollers without causing bruising. Should
any foreign objects enter the hopper e.g.. stones then the flap will retract to
allow the stone to pass through without causing damage.
A single lever situated at the right-hand end of the hopper adjusts the flaps;
each notch in the lever bracket is numbered 1-6 (7). See the seed calibration
charts for the guideline flap setting, Position 1 is for small seeds e.g. rape etc
where the flap is almost touching the roller and position 6 is for large seeds
for example beans. The operator must set the flaps to best suit the seed
being used.
SETTING 2
The variator can be thought of as an infinitely variable gearbox within its lower
0-rpm and upper limit. The sliding scale is split into increments from 0-90 the
number being purely for reference.
Refer to the seed calibration charts in main manual. Each seed type has the
approximate output in Kg/Ha for a particular setting on the variator. Choose
the desired seed rate and therefore variator setting and adjust variator slide
accordingly.
SETTING 3
White plastic blanking covers are used to disengage standard seedwheel;
these are easily put on/taken off, when flaps are in position 6.
Attention: This is only the start of calibration test. The actual sowing
rate must be checked prior to drilling
.
Calibration test.
The following step by step procedure should be adopted to accurately test the
sowing rate.
1.

turning anti-clockwise slightly until locks can be slid upwards, then
retighten.
