To obtain the best results from your granular fertilizers and pesticides, you have to apply them at the correct rate. One easy step you can take to help assure that your spreader delivers the correct rate of material is to calibrate your spreader.

The more you learn about lawn spreaders, the more you realize how complicated they really are. The LSU AgCenter has published a bulletin that summarizes 24 years of research on spreaders.

In some situations, a hand-cranked spreader is more practical than a wheeled model. When spreading granules in nurseries, beds of flowers and ornamentals, and other restricted areas, a wheeled spreader can be difficult or impossible to use. Hand- or strap-carried, hand-cranked spreaders are a viable option in such cases.

A simple hand spreader is often the best tool for applying granular fertilizer or pesticides.

Most professional applicators use rotary spreaders. Rotary spreaders are not only faster than drop spreaders, but are more forgiving of small errors in swath width.

Rotary broadcast spreaders offer many advantages for turf professionals. There are also some disadvantages including pattern skewing and the need to develop pattern settings for each product to center the pattern. Pendulum-action spreaders overcome those problems.

People tend to walk at different speeds. When you are pushing a spreader, this difference in walking speed can cause problems.

Some high-quality plastic spreaders have precision equivalent to the better homeowner metal spreaders. There is a tremendous difference in performance among brands and models.

A good lawn spreader is a precision tool and should be treated accordingly. Your lawn spreader doesn’t need a great deal of time-consuming maintenance, but a few simple steps can preserve the life and precision of your spreader.

Walk-behind lawn spreaders are designed to be pushed, not pulled. The delivery rate from drop spreaders and the pattern from rotary spreaders are distorted if a spreader is pulled backward.
