OPERATING SPEED
The operating speed needs to be selected
as a function of :
- The desired consistency in the row
- The ground conditions
- The density of the seed
A high speed is not conducive to accuracy,
especially in rough or rocky conditions which
causes the unit to bounce.
Likewise, a high seed density may cause the
disc to rotate fast, burdening the metering.
It should also be noted, and especially for
corn, the misshapen and angular seeds are
difficult to sow regularly, especially at high
working speeds.
A base speed of 3 ½ to 4 ½ mph (5/7 km/h)
assures good results for most seeds in the
majority of conditions. However when
planting corn at lighter population more than
6” (15 cm) between the seed, 5/6 mph (8/10
km/h) is quite possible.
For planting of high seed population such as
peanuts, edible beans, and kidney beans,
best results can be obtained by not going
faster than ¾ mph (4,5/6 km/h).
STANDARD RATE DRIVE
Seed planting rate charts are based on the
standard rate drive. The standard rate drive
uses a 30 tooth sprocket on each contact
drive tire.
IMPORTANT : After each sprocket
combination adjustment, make a field
check to be sure you planting at the
desired rate.
