McCulloch M16538H ユーザーズマニュアル

• 

Mower should be properly leveled for best mowing per-

 for mance.  See "TO LEVEL MOWER HOUSING" in the 

Service and Adjustments section of this manual.

•  The left hand side of mower should be used for trim-

 ming.

•  Drive so that clippings are discharged onto the area 

that has been cut.  Have the cut area to the right of the 

machine.  This will result in a more even distribution of 

clippings and more uniform cutting.

• 

When mowing large areas, start by turning to the right 

so that clippings will discharge away from shrubs, 

fences, drive ways, etc.  After one or two rounds, mow 

in the opposite direction making left hand turns until 

finished (See Fig. 11).

•  If  grass is extremely tall, it should be mowed twice to 

reduce load and possible fire hazard from dried clip-

 pings.  Make first cut relatively high; the second to the 

desired height.

•  Do not mow grass when it is wet.  Wet grass will plug 

mower and leave undesirable clumps.  Allow grass to 

dry before mowing.

•  Always operate engine at full throttle when mow-

ing to assure better mowing performance and proper 

dis charge of ma te ri al.  Regulate ground speed by se-

 lect ing a low enough gear to give the mower cutting 

per for mance as well as the quality of cut desired.

•  When operating attachments, select a ground speed 

that will suit the terrain and give best performance of 

the attachment being used. 

To ensure proper operation and performance, it is rec om -

mend ed that the transmission be purged before operating 

tractor for the first time. This procedure will remove any 

trapped air inside the transmission which may have de-

 vel oped during shipping of your tractor.

IMPORTANT:  SHOULD YOUR TRANSMISSION RE QUIRE 

REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD 

BE PURGED AFTER REINSTALLATION BEFORE OPERATING 

THE TRACTOR.

1.  Place tractor safely on a level surface - that is clear 

and open - with engine off and parking brake set.

2.  Disengage transmission by placing freewheel control 

in freewheeling position (See “TO TRANSPORT” in 

this section of manual).

3.  Sitting in the tractor seat, start engine. After the engine 

is running, move throttle control to slow position. With 

motion control lever in neutral (N) po si tion, slowly 

disengage clutch/brake pedal. 

4.  Move motion control lever to full forward position and 

hold for five (5) seconds. Move lever to full reverse 

position and hold for five (5) seconds. Repeat this 

procedure three (3) times.

5.  Move motion control lever to neutral (N) position. Shut- 

off engine and set parking brake.

6.  Engage transmission by placing freewheel control in 

engaged position (See “TO TRANSPORT” in this sec-

 tion of manual).

7.  Sitting in the tractor  seat, start engine. After the engine 

is running, move throttle control to half (1/2) speed. 

With motion control lever in neutral (N) position, slowly 

disengage clutch/brake pedal.

8.  Slowly move motion control lever forward, after the 

tractor moves approximately five (5) feet, slowly move 

motion control lever to reverse position. After the trac-

tor moves approximately five (5) feet return the motion 

control lever to the neutral (N) position. Repeat this 

procedure with the motion control lever three (3) times.

Your transmission is now purged and now ready for normal 

op er a tion.

COLD WEATHER STARTING (50° F and below)

• 

When engine starts, slowly push choke control in until 

the engine begins to run smoothly. Continue to push 

the choke control in small steps allowing the engine to 

accept small changes in speed and load, until the choke 

control is fully in. If the engine starts to run roughly, pull 

the choke control out slightly for a few seconds and 

then continue to push the control in slowly. This may 

require an engine warm-up period from several sec onds 

to several minutes, depending on the temperature.

AUTOMATIC TRANSMISSION WARM UP

•  Before driving the unit in cold weather, the trans mis sion 

should be warmed up as follows:

•  Be sure the tractor is on level ground.
•  Place the motion control lever in neu tral.  

Re lease the parking brake and let the clutch/brake 

slowly return to operating po si tion.

•  Allow one minute for transmission to warm up. This 

can be done during the engine warm up period.

• 

The attachments can be used during the engine warm-

up period after the transmission has been warmed up 

and may require the choke con trol be pulled out slight ly.

NOTE: If at a high altitude (above 3000 feet) or in cold 

temperatures (below 32 F) the carburetor fuel mixture may 

need to be adjusted for best engine performance. See “TO 

ADJUST CARBURETOR” in the Service and Ad just ments 

section of this manual.
