CAUTION 

Before attempting to use your DEK mower, please make sure you 
are familiar with all of the components and have read the manual. 

Operating the Mower (hydro drive models): 

1.  Make sure the brake has 

been moved to the “OFF 
Position. (Figure 3) 

Figure 3 

2.  Push down and hold the 

operator presence control 
levers “A” on the handle bar 
with both hands (Figure 4). 

 
3.  The forward and reverse 

levers (“B” and “C”) are 
spring loaded to the neutral 
position. 

Figure 4 

4.  To drive the mower forward, slide both hands slightly back on 

the handle bar and gently squeeze the forward levers “B” 
toward the handle bar.  The mower will move forward.  The 
forward speed will be directly proportional to the degree of 
movement of these forward levers toward the handle bar. 

5.  To turn the mower left, either release some pressure on the 

left lever (reduces the speed of the left wheel) increase the 
pressure of the right lever (increases the speed of the right 
wheel) or both.  The degree of the turn will be directly propor-
tional to the amount of movement of these levers. 

6.  To turn the mower right, simply perform the functions de-

scribed in instruction 5 with the opposite levers. 

7.  To stop the forward motion of the mower, release the forward 

levers.  The spring loaded feature of the hydrostatic drive 
units will return the levers to the neutral position and stop the 
mower. 

8.  To drive the mower backwards, slide both hands slightly for-

ward on the handle bar and gently squeeze the reverse lev-
ers “C” toward the handle bar.   

9.  When in the neutral position, the hydraulic system will prevent 

the mower from moving easily.  However, on a grade, the 
mower can drive very slowly (with the engine off or running).  
The manual parking brake should be “set” any time the 
mower is left unattended or is being transported. 

10.  To physically move the mower when the engine is 

NOT

 run-

ning, the hydrostatic drive units will need to be disengaged 
(bypassed).  To bypass these hydro units, pull the two levers 
below the rear of the chassis (Figure 5) through the holes and 
slide them in the slots provided.  This will allow the hydraulic 
fluid to bypass the drive wheels and allow the drive wheels to 
move freely. 

 

NOTE: 

Release the bypass levers when the desired mower move-

ment is complete to reengage the hydro drive units.  To release 
thee levers, simply slide the slots to the hole and they will auto-
matically return to their normal closed position. 

Figure 5 

WARNING 

DANGER: Thoroughly inspect the area where the equipment is to 
be used.  Look for items such as stones, sticks , wire, and other 
foreign objects.  When struck by the mower, these and other ob-
jects may become projectiles that could lead to serious injury and 
or death.  Clear area of all debris and keep people and pets away. 

Mowing Grass with Your DEK Lawn Mower 

Hydro by-

pass levers 

NOTE:  The safety interlock system  will prevent the engine 
from being started if the blade control lever is not in the 
“OFF” position 

 

DANGER: DO NOT OPERATE THE MOWER WITH DEFECTIVE 
GUARDS, SHIELDS, OR WITHOUT THE SAFETY DEVICES 
SECURELY IN PLACE. 
 
WARNING:  THIS MOWER IS DESIGNED SO THE BLADES 
WILL COME TO A COMPLETE STOP WITHIN 7 SECONDS OF 
THE BLADE CONTROL LEVER BEING PLACED IN THE “OFF” 
POSITION.  FOR YOUR SAFETY, PLEASE ENSURE IF THE 
BELTS WERE ADJUSTED IN ANY WAY, THAT THE BELT 
TENSIONS ARE RE-CALIBRATED TO MEET THIS SPECIFICA-
TION. 

1.  When the mower is in position on the area to be mowed, 

hold down with one hand the operator presence control. 

2.  With the other hand, SLOWLY push the blade control 

lever forward to the  “ON” position. 

3. 

Belt drive models

—Move the gear shift lever to the de-

sired speed.  Always begin at a slow ground speed and 
increase only as the condition of the terrain warrants. To 
stop mowing, slowly and evenly squeeze up on both trac-
tion control levers until the mower comes to a complete 
stop and  then with your thumbs, push down on the trac-
tion lever locks until the levers are securely locked in the 
neutral position.  Return the gear shift lever to the neutral 
“N” position 

4. 

Hydro drive models

—Slowly, and evenly, engage the 

forward and reverse levers and begin mowing. To stop 
moving, ease up on the levers or simply let go of the 
mower. 

5. 

To stop the blades, pull the blade control lever back to 
the “OFF” position.  

Warning—the blades may take up 

to 7 seconds to stop turning. 

The Soft Start feature is critical to maintaining belt, clutch, and 
engine life.  NEVER “slam” the blade on/off handle from off to 
on without pausing an adequate time in the soft start range.
