3. Using hydraulic controls in the tractor, fully retract the
hydraulic disconnect cylinder (1) to apply product.
Extend the cylinder to stop application.
IMPORTANT: Disengage the chain drive when field
work is complete by reversing step 1 from
above. Do not transport the spreader
when the ground drive is engaged.
Also, make sure the hydraulic disconnect
cylinder is extended to prevent product
from spilling.
CAUTION: Transporting the spreader at high
speeds with the ground drive engaged could
cause serious damage to the spreader.
Setting the Metering Gate Opening
(Mechanical Ground Drive)
The application rate is determined by the metering
gate opening and the speed range (high or low) of the
conveyor chain.
To determine the gate opening:
1. Find the fertilizer density. See “Determining Product
Density” on page 12.
NOTE: If scale is not available, weigh 1 gallon (3.78
Liters) of the fertilizer and then multiply that by
7.5 to establish the product density.
2. Go to the Rate Chart Selector Guide found on page
16. Use this chart to find the correct Application
Rate Chart within this manual that corresponds with
your desired spread width and the machine’s tire
size.
3. Under the “Product Density” row of the Application
Rate Chart, find the value closest to your outcome
from Step 1. Follow this column down to the desired
application rate.
4. Follow this row to the left of the chart to the proper
gate opening size.
