6.12.9 Converging Drum Assemblies –
Grass Seed Header
The twin converging drum assemblies are
designed specifically for grass seed and similar
crops where conditioning is not a requirement.
The hydraulically adjustable drum assemblies
are used to form the desired type and shape of
windrow, depending on crop density, dryness,
and maturity. Refer to Section 6.13, Haying
Tips, for more information.
The position can be controlled from the
windrower cab with the REEL UP and REEL
DOWN switches on the GSL.
The drums are hydraulically driven and the
rotational speed can be varied from 0 to 1000
rpm from the windrower cab with the rotary knob
on the operator’s console.
6.12.10 Windrow Forming Rods
Grass seed headers are equipped with windrow
forming rods, which assist in forming the narrow
windrows preferred for this application. A rod
assembly is installed on the windrower tractor at
either side of header opening.
Adjust the rods as follows to modify the windrow
shape. Use the forming rods in conjunction with
the converging drum deflectors to achieve the
width and shape of windrows you desire.
a. Loosen clamp bolts (A) and move rod assembly
(B) inboard or outboard to achieve desired
swath width.
