CUTTER DECK ADJUSTMENTS
Remove Hair Pins
SWZU05DHA
Due to the many cutting conditions that exist, it is difficult
to suggest a cutter deck setting that will work for every
lawn. There are two adjustments that can be made on
these decks, pitch and height.
PITCH is the angle of the blades in relation to the ground
(comparing front to rear). The pitch of the cutter blades
should be equal between the front and rear for proper
cutting performance. To check for proper deck pitch, be
sure that the mower is on a flat, level surface and the
tires are properly inflated.
HEIGHT is the nominal distance the blade is off of the
ground. This measurement is made with the blades
pointed side to side and distance is measured between
cutting tip and ground.
Changes to the cutting height can be achieved by repositioning the cutter deck. There are eight available positions from 1" to 4-1/2" (See Figure 2).
WARNING:
Do not adjust the cutting height with the mower
blades rotating. Shut off the engine and remove
the ignition key. Bodily injury could occur from
the rotating blades.
Figure 2. Cutting Height Adjustment
CUTTER DECK PITCH ADJUSTMENTS
The cutter deck pitch adjustment has been set at the
factory and normally will not need to be changed.
However, if the pitch needs to be adjusted due to service
work performed on the deck, follow the procedure below
(see Figure 3, Page 11).
1. Shut off the engine and remove the key.
2. Support the cutter deck with four blocks (you
will be removing the hair pins to make this
adjustment).
1. Shut off the engine and remove the ignition key .
2. While holding up on the deck support handle, remove
the two hairpins from the adjusting pins on one side
of the cutter deck (See Figure 2).
3. Lift or lower the deck to the desired cutting height
and reinstall the hairpins. A deck height decal is
located on the deck mounting frame as an aid in
adjusting the deck to the desired height.
4. Repeat the above process on the opposite side of the
cutter deck.
3. Remove the front hair pins from the front deck
support pins.
4. Loosen the jam nuts on the deck support pins.
5. Turn the deck support pins to lengthen or shorten
the pins to reach the desired result.
6. Tighten the jam nut, replace the hair pin, and
remove the blocks. Check that the desired deck
pitch is achieved.

CUTTER BLADES
Do not sharpen beyond 1/3 of the width of the blade.
(See Figure 4).
WARNING:
Blades have a sharp cutting edge. Wear proper
eye protection and protective gloves or wrap
blades with protective material when removing,
sharpening and installing blades.
The Custom-Cut Baffle is designed to deliver optimum
airflow and superior cutting performance in any type of
grass. The Custom-Cut Baffle can be raised or lowered
to precisely tailor the deck's performance for the type of
grass being cut. The baffle can be set in three (3)
different positions for optimum performance.
A. 3" Position - baffle is installed using the top set of
holes on the front baffle welded inside the cutter
deck. (See Figure 6, Page 12). The Velocity-Plus and
Advantage cutter deck will deliver the best qualityof-cut in very tall, wiry , tough to cut grass.
B. 3-1/2" Position (factory setting for advantage cutter
decks) - baffle is installed using the middle set of
holes on the front baffle welded inside the cutter
deck. (See Figure 7, Page 12). For general purpose
cutting, place the Custom-Cut Baffle in the 3-1/2"
position. This gives the best mix of cutting
performance in all types of grass.
C. 4" Position (factory setting for Velocity-Plus cutter
decks) - baffle is installed using the bottom set of
holes on the front baffle welded inside the cutter
deck. (See Figure 8, Page 12). Placing the baffle in
the 4" setting will enhance fall cutting (leaf pickup)
and reduce cutter deck "blowout".
-NOTE-
Dress the blade with a file. Using a wheel
grinder may burn the blade. Check the balance
of the blade. If blades are out of balance, vibration and premature wear of spindle assembly can
occur. See your authorized Scag dealer for
blade balancing or special tools, if you choose to
balance your own blades.

HYDRAULIC SYSTEM
Checking Hydraulic Oil Level
The hydraulic oil level should be checked after the first 8
hours of operation. Thereafter, check the oil every 100
hours of machine operation or monthly , whichever occurs
first.
-IMPORTANT-
If the oil level is consistently low , check for leaks and
correct immediately .
1. Wipe dirt and contaminants from around the
reservoir cap. Remove the cap from the hydraulic oil
reservoir.
2. Visually check the level of hydraulic oil. Hydraulic oil
must be at least 2 inches from top of the filler neck.
If the level cannot be determined visually, use a clean
tape measure to check the level. If the fluid is low,
add 20W50 motor oil. DO NOT overfill; (overfilling
the oil reservoir may cause oil seepage around the
cap area).
2. Place a suitable container under the hydraulic oil
drain. Remove the fill cap from the reservoir.
Remove the drain cap from the T-Fitting located on
the hydraulic system filter head. (See Figure 12).
Allow the fluid to drain into the container and
properly discard it.

3. Clean the fill cap and install it onto the reservoir.
Changing Hydraulic Oil
The hydraulic oil should be changed after every 500
hours or annually, whichever occurs first. The oil should
also be changed if the color of the fluid has become
black or milky . A black color and/or a rancid odor usually
indicates possible overheating of the oil, and a milky color
usually indicates water in the hydraulic oil.
-NOTE-
The hydraulic oil should be changed if you
notice the presence of water or a rancid odor
to the hydraulic oil.
1. Park the mower on a level surface and stop the
engine.
-NOTE-
Before refilling the hydraulic oil reservoir the
hydraulic oil filter should be changed as well.
See instructions outlined below.
4. Fill the reservoir to 2 inches from the top of the filler
neck with 20W50 motor oil.
5. Replace the reservoir fill cap. Start the engine and
drive forward and backward for two minutes.
Check the oil level in the reservoir. If necessary, add
oil to the reservoir.
Changing Hydraulic Oil Filter Element
The hydraulic oil filter should be changed after every 500
hours of operation or annually , whichever occurs first.
1. Remove the oil filter element (Figure 12) and
properly discard it. Fill the new filter with clean oil
and install the filter. Hand tighten only .

add SAE 20W50 motor oil.
Checking Engine Crankcase Oil Level
The engine oil level should be checked after every 8
hours of operation or daily as instructed in the Engine
Operator’s Manual furnished with this mower .
Changing Engine Crankcase Oil
After the first 20 hours of operation, change the engine
crankcase oil and replace the oil filter. Thereafter,
