Driving On Windrow; Raking And Tedding; Chemical Drying Agents - MacDon D65 Operator's Manual

Configuration
High and fluffy
Consistent formation, not bunchy
Even distribution of material across windrow
Properly conditioned

4.11.5 Driving on Windrow

Driving on previously cut windrows can lengthen drying time by a full day in hay that will not be raked. If practical,
set forming shields for a narrower windrow that can be straddled.
NOTE:
Driving on the windrow in high yielding crops may be unavoidable if a full width windrow is necessary.

4.11.6 Raking and Tedding

Raking or tedding speeds up drying, however, benefits must be evaluated against additional leaf losses which will
be the result.
There is little or no advantage to raking or tedding if the ground beneath the windrow is dry. Large windrows on
damp or wet ground should be turned over when they reach 40–50% moisture.
Hay should not be raked or tedded at less than 25% moisture, or excessive yield losses will result.

4.11.7 Chemical Drying Agents

Hay drying agents work by removing wax from legume surfaces, enabling water to escape and evaporate faster.
However, treated hay lying on wet ground will also absorb ground moisture faster. Before deciding to use a drying
agent, costs and benefits relative to your area should be carefully evaluated.

OPERATION
Advantage
Movement of air through the windrow is more important to
the curing process than is direct sunlight.
Permits an even flow of material into the baler, chopper,
etc. and allows for more even drying.
Results in even and consistent bales to minimize handling
and stacking problems.
Prevents excessive leaf damage.
