Spinners
IMPORTANT!
Keep your spinners clean. The smallest amount of build-up, rust, or
anything that causes a rough surface will affect the outcome of the spread
pattern.
Spinner RPM
– Spinners are powered by the tractor’s remote hydraulic ports. They are
controlled by the priority valve supplied with the hydraulic spinner system. The key to keeping
proper spinner speed is having enough oil supplied by the tractor to allow the priority valve to
maintain excess flow.
Proper spinner speed adjustment is very important in obtaining good spread patterns. Its use will
depend entirely on the material being spread. Once set for a particular material, use a marker to
label the location of the flow control lever so as to avoid having to rerun the trial and error
testing for that particular material again.
The particle size will also determine the maximum spread pattern width. The spread pattern can
vary anywhere from 25 ft for powder type materials such as lime or up to 60 ft for fertilizer
pellets.
Spinner speed will vary depending on the type of material being spread. The size and weight of
the particle determine the speed required. Too high a spinner speed will dump everything behind
the tractor. For finely powdered materials the speed will be fairly low but for large particle
materials, the speed may be very high.
Perhaps the best way to adjust the spinner speed is to observe the way material spins off the
spinner. At slow speed the material leaves the blades in bands. At medium speeds it forms wide
bands in the air, and at higher speeds the bands form into one thick blur.
DO NOT STAND ON THE FENDER WHILE THE SPREADER IS IN MOTION
Material Flow Divider
The material divider should be adjusted in conjunction with spinner speed to obtain the best
spread pattern. Moving the divider forward will increase the amount of material directly behind
the tractor, moving to the rear will decrease the same. Trial and error will help determine the
correct position most of the time. After experience is obtained with a variety of materials, the
trial and error will become less and less of an effort but never completely eliminated.
Here are some common results of spread pattern tests and how to correct them.
Pattern 1:
Two heavy swaths located directly behind the spinners; material is seen blowing
over the tops of the spinners.
Cause: Spinner speed too fast, material blows over the tops of the spinners and falls to the
ground directly behind the unit.
Cure: Decrease spinner speed.
Pattern 2: Heavy on one side only.
Cause: 1. More material is being deposited on one spinner.
2. Material has collected on the divider panels.
Cure: 1. Accurately measure the position of the flow divider and adjust if necessary.
2. Keep divider scraped clean of material build-up.
