CUTTING GRAIN FOR SILAGE OR HAY
Rye, oats, barley, or wheat are often cut for silage or
hay. These crops should feed through the header
and conditioner, without problems, if the crop is taller
than 1 m (36"). If these crops are shorter or not fully
headed, the crop may stop or bunch up between the
reel and conditioner rolls. Back up about 300 mm
(12") and raise the header partway to help feed large
bunches through the conditioner rolls.
If the grain is too stiff stemmed and slippery, it will not
lay down in front of the rolls and feed through
smoothly. If ground speed is too slow, or the operator
has to stop too often, make the following
adjustments:
WARNING
Disengage the PTO, turn off the tractor engine
and remove the key. Wait for all movement to
stop before leaving the operator's position.
Never adjust, lubricate, clean or unplug machine
with the engine running. Failure to comply could
result in death or serious injury.
1. Move push bar, 1, down.
IMPORTANT: Do not set the push bar too low. Long
stems may become tangled in the reel before they
are cut off, and the push bar or reel could be
damaged.
2. Move the reel back at 2, and down at 3, so the
reel is close to the rolls and header floor pan. If
the cutter bar plugs, set the reel within 6 mm
(1/4") of the top of the guards.
3. If plugging at the cutter bar is not a problem,
reduce the reel speed. Be sure the reel drive
pulley is set at the lowest speed.
If the cutter bar is not plugging, install the optional
"Reel Speed Reduction Sprocket" for cutting
grain crops.
4. Tilt the header back so the header is close to the
conditioner rolls. The upper header links can be
adjusted shorter or the drilled pin can be set in the
rear hole of the optional "Hydraulic Guard Angle
Adjusting Kit."
5. Extend the lift cylinders 50 mm to 75 mm (2" to
3") to raise the trail frame. Material will feed lower
on the bottom roll.
6. Reduce conditioner roll pressure. Add additional
shims at the roll stops.
7. Try different ground speeds to get uniform
feeding to the rolls and acceptable stubble
length.
8. Taller, more mature crops may feed through the
header without bunching in front of the rolls.
