OPERATION
WINDROW CHARACTERISTICS
Factors such as ground speed, reel speed, draper speed and delivery opening will all affect the resulting
windrow. You will quickly become adept at adjusting these variables to achieve the desired results.
NOTE: Crop condition is a major factor in forming a good windrow. While standing or uniformly leaning crops
can generally be easily formed into an acceptable windrow, such is not the case when stalks are tangled or
leaning in several directions.
There are three basic criteria by which the quality of a windrow is measured:
1. Weight Distribution - heads and stalks distributed evenly across full width of windrow.
2. Good Curing - a loose, open windrow for better drying.
3. Good Weatherability - a well formed windrow that supports heads off the ground and holds together in
extreme weather conditions.
HERRINGBONE WINDROW
The most desirable form of windrow, stalks are
crossed and interwoven. Heads are distributed
across full width of windrow. Windrow rating:
Weight Distribution: Good
Curing Characteristics: Good
Weatherability: Excellent
FANTAIL WINDROW
The stalk tips are crossed in the center and heads
are in line along outside edges. Windrow rating:
Weight Distribution: Fair
Curing Characteristics: Fair
Weatherability: Fair
DOVETAIL WINDROW
The stalk tips are lined along outside edges of
windrow and heads are crossed in center.
Windrow rating:
Weight Distribution: Poor
Curing Characteristics: Fair
Weatherability: Poor
PARALLEL WINDROW
The stalks are parallel to windrow and heads
evenly distributed across width of windrow.
Windrow rating:
Weight Distribution: Good
Curing Characteristics: Good
Weatherability: Good
