NOTE: Under certain conditions when tractor is standing idle with the eng!ne running, hot engine exhaust gases may cause "browning" of grass. To eliminate this possibility, always stop engine when stopping tractor on grass areas,

pletely, as described above, before leav- ing the operator's position; to empty grass catcher', etc.

TO USE THROTTLE CONTROL (See Fig. 6) Always operate engine at full throttle

Operating engine at less than full throttle reduces the battery charging rate

o Full throttle offers the best mower performance.

TO USE CHOKE CONTROL (See Fig. 6)

Use choke control whenever you are starting a cold engine, Do not use to start a warm engine

To engage choke control, pull knob out Slowly push knob in to disengage_

TO MOVE FORWARD AND BACKWARD (See Fig. 6)

The direction and speed of movement is controlled by the gearshift lever

Start tractor with clutch/brake peda! depressed and gearshift lever in neutral (N) position_

Move gearshift and range shift levers to desired posi- tion,

Slowly release clutch/brake pedal to start movemenL

IMPORTANT: BRING TRACTOR TO A COMPLETE STOP BEFORE SHIFTING OR CHANGING GEARS. FAILURE TO DO SO WILL SHORTEN THE USEFUL LIFE OF YOUR TRANSAXLE

TO ADJUST MOWER CUTTING HEIGHT

(See Fig. 6)

The cutting height is controlled by turning the height adjust- ment knob in desired direction

Turn knob clockwise (t_,_) to raise cutting height

=Turn knob counterclockwise (_) to lower cutting height.

The cutting height range is approximately 1-1/4" to 4-1/4" The heights are measured from the ground to the blade tip with the engine not running. These heights are approxi- mate and may vary depending upon soil conditions, height of grass and types of grass being mowed_

The average lawn should be cut to approximately 2-1/2 inches during the cool season and to over 3 inches during hot months. For healthier and better looking lawns, mew often and after moderate growth.

°For best cutting performance, grass over 6 inches in height should be mowed twice_ Make the first cut relatively high; the second to desired height,
