Choosing a Granular Spreader
Misusing your spreader or choosing the wrong style can cause you to waste your time and money when you apply your product. You need to figure in several factors when choosing a spreader:
The size of area to be covered
The characteristics of the product you plan to use
If the settings of the spreader can be modified
Uniformity of spreading ability
The cost of the spreader
You also need to consider what type of spreader you need. Most commonly you will find broadcast spreaders, also called rotary spreaders, and drop spreaders. Here are the differences:
Broadcast spreaders: These spreaders have a hopper that you put your granular product in, with one to three holes on the bottom, which can be adjusted and closed. The granules fall through the holes onto a rotating plate that spreads the product out on the ground. The drop pattern of these spreaders is wider than the hopper itself. Often times you will have to work in an overlapping pattern, because the margins of the drop patterns often contain less material.
Drop spreaders: This type of spreader is generally more precise, yet slower in application. There are holes lined up along the bottom with an agitator to distribute the product through the holes. The hole sizes are adjustable and the product is only dropped in the range of where the holes are. This type is great for smaller areas.
