OPERATING THE MOWER CONDITIONER
Characteristic Advantage
High and fluffy Movement of air through windrow is more important to the curing process
than direct sunlight.
Consistent formation, not bunchy Permits an even flow of material into the baler, chopper etc.
Even distribution of material across
windrow Results in even and consistent bales to minimize handling and stacking
problems.
Properly conditioned Prevents excessive leaf damage.
7.13.5 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.
7.13.6 Raking and Tedding
Raking or tedding speeds up drying, however the benefits must be weighed against the additional leaf losses which
will 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.
7.13.7 Using 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 compared.
