Poulan PP21H42 manual To Move Forward and Backward, To USE Cruise Control

TO USE THROTTLE CONTROL (See Fig. 5)

Always operate engine at full speed (fast).

•Operating engine at less than full speed (fast) reduces engine's operating efficiency.

•Full speed (fast) offers the best mower performance.

TO MOVE FORWARD AND BACKWARD

The direction and speed of movement is controlled by the forward and reverse drive pedals.

•Start tractor and release parking brake.

•Slowly depress forward or reverse drive pedal to begin movement. Ground speed increases the further down the pedal is depressed.

TO USE CRUISE CONTROL

The cruise control feature can be used for forward travel only.

SYSTEM CHARACTERISTICS

The cruise control should only be used while mowing or transporting on relatively smooth, straight surfaces. Other conditions such as trimming at slow speeds may cause the cruise control to disengage. Do not use the cruise control on slopes, rough terrain or while trimming or turning.

•With forward drive pedal depressed to desired speed, move cruise control lever forward to “SET” position and hold while lifting your foot off the pedal, then release the cruise control lever.

•To disengage the cruise control, pull the lever backward to “OFF” position, or fully depress the brake pedal.

TO ADJUST MOWER CUTTING HEIGHT (See Fig. 6)

The cutting height is controlled by turning the height ad- justment knob in desired direction.

•Turn knob clockwise ( ) to raise cutting height.

•Turn knob counterclockwise ( ) to lower cutting height.

The cutting height range is approximately 1-1/2" to 4". The heights are measured from the ground to the blade tip with the engine not running. These heights are approximate 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, mow 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.

TO ADJUST GAUGE WHEELS (See Fig. 7)

Gauge wheels are properly adjusted when they are slightly off the ground when mower is at the desired cutting height in operating position. Gauge wheels then keep the deck in proper position to help prevent scalping in most terrain conditions.

NOTE: Be sure tractor is on a flat level surface.

•Lower mower and adjust mower to desired cutting height(See “TO ADJUST MOWER CUTTING HEIGHT” in this section of manual).

•Remove retainer spring and clevis pin which secure each gauge wheel bar.

•Lower gauge wheels to ground. Raise gauge wheels slightly to align holes in bracket and gauge wheel bar and insert clevis pin. Gauge wheels should be slightly off the ground.

•Replace retainer spring into clevis pin.

•Be sure all gauge wheels are in the same setting.

IMPORTANT: BE SURE TO READJUST GAUGE WHEELS IF YOU CHANGE THE CUTTING HEIGHT OF THE MOWER DECK.

TO OPERATE MOWER (See Fig. 8)

Your tractor is equipped with an operator presence sensing switch. Any attempt by the operator to leave the seat with the engine running and the attachment clutch engaged will shut off the engine. You must remain fully and centrally positioned in the seat to prevent the engine from hesitating or cutting off when operating your equipment on rough, rolling terrain or hills.

•Select desired height of cut.

•Lower mower with attachment lift control.

•Start mower blades by engaging attachment clutch control.

•TO STOP MOWER BLADES - disengage attachment clutch control.
