DRIVE CONTROL

The drive system consists of a two speed transmission and an 
adjustable belt drive from the engine to the transmission.

The transmission speed can be set to 

LO - N - HI

HI speed is approximately  4mph - a fast walking speed.
LO speed is approximately 3mph - an average walking speed.

The shifter arm is intentionally made 

fl

 exible.  When the arm is 

locked in the 

LO

 or the 

HI

 position the transmission will 

automatically mesh into the gears as soon as the drive is 
engaged by operating the lower control bar. 

ENGAGING THE DRIVE

To engage and disengage the drive system pull up on the 
lower control bar (1).  Typically the drive will engage when the 
lower control bar is approximately 1 to 1.5 inches from the 
handle (2). 

Notice

Due to wear, the drive engagement position of the lower 
control bar can change.  If the distance between the lower 
bar and the handle (2) is less than a 1/4 inch when the mower 
starts to drive make an adjustment on the red knob located 
below the engine fuel tank (3).  
If needed turn the red knob 2 turns clockwise.  Verify the drive 
position of the control  bar by operating the mower.  If needed 
repeat the adjustment.

HEIGHT ADJUSTMENT

Each wheel can be adjusted individually to a speci

fi

 c cutting 

height from 1 inch to 4.5 inch.  

Notice: It is only possible to 

move the adjustment on one side 2 - 3 steps each time.
 

 

Moving the front wheel height adjusters forward raises the 
cutting height.  Moving the rear wheel height adjusters towards 
the rear of the mower raises the rear cutting height.  

Always adjust the height adjusters to the same position both in 
the front and the rear for best cutting results.

WARNING

Never readjust the cutting height while the engine 
is running.  STOP the engine.  Never lift the 
mower by placing your hand or 

fi

 ngers under the 

edge of the mower deck.
