1. QUALITY AND CHARACTERISTICS
It is very important to choose a high-quality topdressing substrate.
For greatest cost eciency, Ecolawn recommends using a bulk
substrate which is friable, has a moisture content lower than 65%,
and contains no inorganic matter (plastic, glass, or concrete, etc.) or
raw organic matter (such as pieces of wood, raw manure).
2. FRIABILITY
A friable material is one that crumbles easily into small fragments.
A substrate that is not very friable appears to be composed of
numerous, compact pieces which do not readily break down.
Screening a substrate makes it much more friable. Additionally, a
substrate containing 10% sand is more friable and will ow more
smoothly and eciently through the applicator.
3. MOISTURE CONTENT
A substrate with a moisture content greater than 65% will tend to
stick to the inside walls of the Hopper and other parts of the spreader.
When working with a substrate with a high moisture content, coat
the insides of the Hopper and the Spreading Disk with a lubricant.
To help the substrate ow freely from the Hopper, stop the machine
and loosen with shovel. This will loosen the substrate so that it can
ow freely from the Hopper.
