2. Set gauge
Refer to the factory-calibrated Gandy rate chai1s in
cluded with your Gandy spreader for a suggested
gauge setting. Move gauge away from the stop before
attempting adjustment. Turn gauge to desired number,
using the top edge of the stop as the setting indicator.
You can 'fine tune' the gauge with extreme precision.
The gauge is marked in increments of one. If you ad
just one tenth of one gauge stop, from 27.7 to 27.8, for
example, the slide will open approximately one thou
sandth of an inch more. The fine adjustments are pos
sible because the gauge is attached directly to the
slide-there is no error through linkage slack.
Remember the settings in the charts are guides for be
ginning. Check your results as outlined in Step 3 and
make adjustments as necessary.
NOTE:
Always move
the gauge away from the stop before attempting to set
the gauge.
3 Check rate
Making a precision application is now simply a
matter of filling up the hopper, moving the lever
so the gauge is against the stop, walking at your
elected speed, and checking your rate.
Most rates are expressed in pounds applied per
thousand square feet. Check your rate as follows;
Fill the hopper level full. Treat a lmown area,
such as 1,000 square feet. Weigh enough materi
al to more than fill the hopper level again. Refill
the hopper level full and weigh the material left
over to see how much was applied in the 1,000
feet. If necessary, adjust gauge up or down and
check again.
You can make a check on smaller areas, such as
500 square feet or 250 square feet, using 1/2 or
1/4 of the rate per 1,000 feet.
It is imp011ant that you check your rate to see
that the setting you chose from the chart is giv
ing you the results you want. Atmospheric con
ditions alone can affect the flow of materials.
CAUTION:
When applying high potency ferti
lizers that will burn, be sure to be moving when
beginning application.
