Check knife drive belt tension (single or untimed knife)
2. Loosen the two bolts (A) that secure the motor assembly to the header end sheet (see
figure 7.103 at right).
3. Turn adjuster bolt (B) clockwise to move the drive motor until a force of 20 ft·lbf (80 N·m)
deflects the belt ¾ inches (18 mm) at mid-span.
To prolong belt life do not overtighten. Please refer to the maintenance and servicing section of your operators manual
Check knife drive belt tension (timed double knifed)
1. Open end sheet.
2. Loosen the two bolts (A) on drive belt idler bracket (see figure 7.117 at right).
3. Position pry bar under idler bracket, and push bracket upwards until a force of 6 ft·lbf (27
N·m) deflects the timing belt ½ inch (13mm) at mid-span.
4. Tighten nuts (A) on idler mounting bracket.
5. Loosen bolts (B) and adjust guide (A) shown in figure 7.118 on right. The measurement
should be 0.02-0.04 inches (0.5 –1.0 mm).
6. Readjust tension of a new belt after a short run-in period (about 5 hours).
Check for Loose Hardware
Check for loose hardware and tighten to required torque. Refer to torque specifications section of operators manual.
Check knife drive box mounting bolts
Check the four knife drive box mounting bolts (A1, A2) torque after the first 10 hours
operation and every 100 hours thereafter. Tighten knife drive box side bolts (A1) first,
then the bottom bolts (A2). Torque to 200-ft lbs (271 N m).

Check Reservoir Hydraulic Fluid on Combine Adapter
Check fluid level every 25 hours with cutterbar just touching the ground. Check when oil is
cold and with center link fully retracted. At ambient temperatures above 95ºF (35ºC) it may
be necessary to lower oil level slightly to prevent overflow. CA20 and CA25 combine
adapters use 15w –40 engine oil in this reservoir. For other models please refer to your
operators manual to find the correct fluid requirements for your specific equipment.

CAUTION: Never use gasoline, naphtha or any volatile material for cleaning purposes. These materials may be toxic
and/or flammable.
CAUTION: Cover cutterbar and knife guards to prevent injury from accidental contact.
1. Clean the header thoroughly.
2. Store the machine in a dry, protected place if possible. If stored outside, always cover with waterproof canvas or other protective material.
3. If machine is stored outside, remove drapers and store in a dark, dry place.
NOTE: If drapers are not removed, store header with cutterbar lowered so water/snow will not accumulate on drapers. This
accumulation of weight puts excessive stress on drapers and header.
4. Lower header onto blocks to keep cutterbar off the ground.
5. Lower reel completely. If stored outside, tie reel to frame to prevent rotation caused by wind.
6. Repaint all worn or chipped painted surfaces to prevent rust.
7. Loosen drive belts.
8. Lubricate the header thoroughly, leaving excess grease on fittings to keep moisture out of bearings. Apply grease to exposed threads,
cylinder rods, and sliding surfaces of components. Oil knife components to prevent rust.
9. Check for worn or broken components and repair or order replacement from your MacDon Dealer. Attention to these items right away will
save time and effort at the beginning of next season.
10. Replace or tighten any missing or loose hardware.

Setting Auto Header Height Control
3. Unlock float handles
(below) on each side of
combine adapter. Up is
locked, down is unlocked.
4. With stabilizer wheels fully raised and header resting on
ground, slightly raise and lower combine feeder house while
monitoring the float indicator (A) to verify that indicator has full
range from 0 –4 and that needle doesn’t stick.
1. Ensure that header float is properly adjusted. Reference the float adjustment section or watch float and
wing balance video series at http://www.macdon.com/videos
2. Perform a header calibration on your combine (refer to operators manual). In some cases the voltage
range will need to be adjusted on the float indicator potentiometer before the combine will calibrate. If
required, then please refer to your header operators manual for this adjustment procedure.
5. Adjust feeder house height until float needle indicates position 2. This is the recommended ground
pressure start point. In wet conditions this may need to be lighter (i.e.1.5)
6. Save float indicator position 2 on your combines auto header height control.
7. With combine parked and header completely lowered, increase combines auto header height control
sensitivity until combine feeder house begins to “hunt” or to automatically raise and lower with the combine
parked stationary. Slightly decrease sensitivity until feeder house stops “hunting”.
8. When cutting on the ground, float should range from 1-3 on indicator (A) above, with the auto header
height control correcting the needle back to position 2 reasonably quickly. When cutting on the ground, it is
important that AHHC maintain a range from 0.5-3 on the float indicator since this will keep float springs
properly tensioned resulting in correct header ground pressure the best terrain following performance. When
cutting off the ground using AHHC (see page 15) needle might be set to position 1 and range from 0-2.
Header Float (A)
Header Tilt (B)
MacDon auto header height control (AHHC) functions by sensing the
separation (or float) between the header and the combine adapter.
The header senses and follows the terrain by riding lightly along the
ground suspended from the combine adapter under spring tension. If
the header floats up or down off of the combine adapter following the
terrain, then AHHC will sense this and will adjust the feeder house
and combine adapter to follow the header either up or down.

Stabilizer Wheel Operation
Adjusting Slow Speed Transport Latch
If slow speed transport latch is difficult to engage (A in
figure 4.100), then adjust wheel hang height on rear axel
by loosening jam nut and turning bolt at rear axel swing
joint using a ¾” or 19mm wrench and socket (see E and
D in figure 3.46 below). Retighten jam nut after adjusting.
•Please Refer to Maintenance and Servicing Section of Operators Manual
***Important: There should only be one point of contact with the ground
at any time, either the cutterbar, skid shoes or stabilizer wheels****
When cutting on the ground: All stabilizer wheels should be locked into the
highest notch with wheels completely off the ground.
When cutting off the ground:
ØHeaders equipped with stabilizer wheel slow speed transport:
Wheels should be adjusted so that the spring is compressed to between 2 and 3 on
the stabilizer wheel compression gauge (see figure 1). Depending on header
configuration, it might be necessary to adjust LH and RH wheels to different notches
to achieve this proper compression and level cut height.
ØHeaders equipped with the stabilizer wheels only (non transport):
Operate with springs compressed as shown in figure 2. Total spring compression
should be 11.6 –13.6 inches (295-345 mm). It might be necessary to adjust LH and
RH wheels to different notches to achieve proper compression and level cut height.
Auto header height control when cutting off the ground: To operate with
AHHC when cutting off the ground, it might be necessary to lighten float or to add
slightly more compression to stabilizer wheel springs so that the header will float
upward off of adapter to sense terrain. Ensure that float is unlocked and properly
adjusted (see page 20), do not over compress springs as this may result in hazard or
damage to the shock and spring assembly. See page 14 for setting of AHHC.

Straight Cut Canola Optimization
Draper Clinic Handout

Optimize Reel Cam Position for Canola
•In standing shatter prone canola, the reel should be retracted as far
back (Aft) as possible to contain shatter loss onto the draper table.
Reel cam positions should also be adjusted to release crop and
prevent carry around. Reel cam positions are adjusted on the right
end of each reel. Please see page 11 of this document for further
information on reel cam positions and how to adjust them.
Optimize Header Tilt for Canola
•Retracting header tilt angle to position “A” or “B” will extend
the feed drum further into the crop and may aid crop
feeding in some high volume crop conditions.
Optimize Cross Auger, Reel & Side Drapers for Canola
•Leave Center Beaters on UCA. In these ripe fluffy conditions
they aid in crop delivery into Feed Auger.
•Reel Position
•As far rearward (Aft) as possible, delivering crop flow
into UCA, ensuring reel is behind C-bar.
•Reel height so that fingers just engage the crop. If reel is
too low it can hamper crop flow.
•Reel Cam set to position 1.
•Speed equal to ground speed.
•Side Draper Speed
•Full Open on CA20
•Position 9 on CA25
