A40-D Self-Propelled
Header
Angle
(1)
Header angle is the angle between the guards
and the ground. It is adjustable to
accommodate soil type and/or conditions.
Hydraulic Link:
Determined by length of hydraulic center-link and displayed as a
value from 0 (shallow) to 10 (steep) on the windrower control
module (WCM). Adjust with controls in windrower cab.
Mechanical Link:
Determined by length of link (short for shallow, long for steep).
Knife
Speed
(2)
High: 1850–1950 SPM
Medium: 1600–1800 SPM
Low: 1400–1600 SPM
Displayed as strokes per minute on the windrower cab
display module (CDM). Adjust with controls in windrower cab.
Knife adjustment on low HP windrowers (M100 and M105) is
done directly on the pump.
Reel
Speed
(3)
Operate the reel at suggested percentage
above ground speed.
Displayed as mph, km/h, or rpm on the windrower cab
display module (CDM). Adjust with controls in windrower cab.
Low HP windrowers (M100 and M105) may not have reel
speed display capability, and require an expansion module to
display reel speed and knife speed. The expansion module
is available as an option.
Auger
Speed
(4)
Increase auger speed at high ground
speed or in heavy crop conditions.
Decrease auger speed at low ground
speed or in light crop conditions.
Refer to auger header operator’s manual
for detailed adjustment instructions.
Displayed on the cab display module (CDM) as auger rotational
speed. Values range from 4.7–9.9. Adjust with controls in
windrower cab.
Float
(5)
Increase float setting in rough terrain or at
high ground speeds to prevent excessive
header movement.
Adjustable springs on the windrower header lift system.
Use in-cab controls for fine adjustments.
Feed Pan
/ Rock
Drop
Tine
Position
(6)
Lower the feed pan in heavy crop to help
prevent plugging.
Raise the feed pan in light crop to form an
even windrow.
1. Loosen bolt (A) at each end.
2. Move tines and pan (B) as required.
3. Tighten bolts (A).
Roll Gap
(7)
Roll gap (C) determines the amount of
conditioning and is preset at 6 mm (1/4 in.).
Increase roll gap to reduce conditioning: Loosen jam nut (D),
and turn lower nut (E) clockwise. Tighten jam nut (D).
Reduce roll gap to increase conditioning: Loosen jam nut (D)
and turn lower nut (E) counterclockwise. Tighten jam nut (D).

ALean Bar
 Height should be set at 2/3 (two-thirds) of the crop height.
 In crops over 1.52 m (5 ft.), an optional Tall Crop Divider kit (MD #B4690) is available that
includes lean bar extensions to raise the lean bar.
BSkid Shoe
 Cutting height is controlled with a combination of skid shoes or gauge rollers, and header
angle adjustment—NOT with the header lift cylinders.
 Adjust as follows:
1. Remove clevis pin (X).
2. Adjust skid shoe (B).
3. Install clevis pin (X).
CCenter Baffle
 Use full raised position for narrower windrows.
 Lower 1 or 2 notches to prevent crop from being projected over forming shield.
 Use fully lowered position for maximum swath width.
DReel Cam
 The reel cam at the right end of the reel controls the aggressiveness of the reel tines which
affect the crop flow into the auger.
 To change reel tine aggressiveness, loosen bolts securing cam disc to end sheet. Tighten
bolts after adjusting cam disc. Refer to the header operator’s manual.
 To increase tine aggressiveness, turn front adjuster bolt to lower the front of cam disc and
turn the rear adjuster bolt to raise the rear of cam disc. Turn bolts by equal amounts.
 To decrease tine aggressiveness, turn front adjuster bolt to raise the front of cam disc and
turn rear adjuster bolt to lower rear of cam disc. Turn bolts by equal amounts.
ERear Baffle
 Raise or lower baffle to adjust the angle.
NOTE: SP rear baffle has handles that must be loosened to move the baffle.
 Lower positions create fluffy windrows. If baffle is too low, an uneven windrow may result.
 When using the DWA (SP), position rear baffle in highest position.
If necessary, lower the left side to direct crop onto the DWA belt.
FForming Shield
Adjustment
 Remove hairpin, and lower or raise shield with straps to the desired height. Install hairpin.
 Generally, the fourth hole from the top is a good starting position.
 Lower the shield if crop is not hitting the top cover.
 Use highest position with the DWA (Remove center deflectors to improve
crop flow to DWA).
GForming Shield
Deflectors
 Adjust both side deflectors to the same hole position to ensure windrow placement is
centered with respect to carrier/drive wheels.
H
Reel Position
 Maintain 2–10 mm (3/32–13/32 in.) clearance between reel tines and pan.
 Reel can be moved forward to improve crop lifting action in lodged crops, or rearward for
lighter crop conditions.
J
Auger to
Stripper Bar
Clearance
 Maintain proper clearance between auger flighting and stripper bars.
Refer to the header operator’s manual.
