A drop spreader applies a fairly even distribution which is a real benefit. This is because the distance between the wheels is limited and so the pattern remains tight. Generally this is very advantageous except when working around trees and shrubs when it can be a bit of a pain.
A rotary spreader has a wider distribution pattern and it can cover a larger area in a lot less time but the outer edge of the pattern is rather uneven and can be sporadic so overlapping application is advisable.
Calibrating A Drop Spreader
1. Check all parts for proper functioning starting at the top and working through to the bottom.2. Mark the area so that you will cover 100 square foot areas. You will need to know the width of the spreader to do your calculation.3. Fill the spreader with the material you will be using - lawn seed, fertilizer, lime, etc. Fill only to the level indicated by the directions.4. Make a trial run over the area so that you can see how the spreader works. Remember that if you open the spreader before it is moving you will get uneven distribution. Open and close smoothly.5. The weight of the material you are applying determines how it will be spread with the spreader. Remember it is part of the equation.6. Do your calibration according to the directions on the bag.7. Begin the calibration at the lowest setting and then gradually move up as required.8. One of the settings should be the correct rate for the material you are working with. Careful calibration is very important.
Calibrating A Rotary Spreader
1. Check that all parts on your spreader are operating correctly starting at the top and working through to the bottom.2. Fill your hopper half full with the material you will be working with3. Since rotary spreaders don't apply evenly with more material applied in the middle. So the width of your application is only accurate to about 60%. So if your width is 12 feet it's only accurate to about 8 feet center. Once you determine this band application is easy.4. Mark off your test area for a 1000 square foot area.5. Determine the amount of material you will need to apply by determining the material weight and the flow. Always do a test push before doing the complete application.6. Repeat the procedure.7. Select the setting that is closest to the desired rate of material distribution.
There have been a great deal of technological changes to the modern fertilizer spreader. This new technology allows for wider patterns and less damage and understanding this technology is important to ensuring you choose the right spreader for the job you've got to do.
And of course once you have the right spreader these fertilizer spreader settings will help you get things operating smoothly.
