4.Electric PTO clutch switch (Fig. 3-2)a two- position switch which controls the electric clutch on the PTO shaft. Down position is OFF and up position is ON. When clutch switch is on, the PTO shaft rotates and delivers live power to attachment requiring it.

IMPORTANT: Never engage clutch with engine running at high rpm. Clutch, drive line or attachment could be damaged.

WARNING: Never turn the PTO switch ON unless the PTO shaft is securely connected to a power driven attachment.

5.Neutral locks (Fig. 3-4)front and rear locking devices hold the steering control lever in a neutral position as tractor will not move when the engine is running and drive pump is operating. Rotating the front lock, up and forward, allows the control levers to be moved forward. Lifting the rear lock with toe of operator’s foot allows the control lever to be moved in reverse.

6.Steering control lever (Fig. 3-4)this lever controls tractor speed and direction. The lever is used to steer, accelerate, brake, and change direction.

7.Pump clutch lever (Fig. 3-5)this lever engages and disengages the hydraulic pump drive belt. Push forward on lever to engage the hydraulic pump drive. Pull back on lever to disengage.

IMPORTANT: Always let the engine warm up to operating temperature and set the throttle at a moderate rpm before engaging the hydraulic pump clutch. Engage the clutch slowly. Sometimes more than one attempt is necessary, particularly when the oil is cold and thickened. Never snap the clutch to engage. Allow the machine to run and warm the oil a short time before driving or using hydraulics.

8.Parking brake lever (Fig. 3-5)engage the parking brake by rotating the lever up and back until it over- centers and locks. Release by rotating the lever forward and down.

WARNING: The parking brake is not designed to hold tractor on steep slopes.

9.Attachment lift lever (Fig. 3-6)This lever controls the hydraulic raising and lowering of tractor tool bars and front end attachments. Pull lever back to raise the bars and push it forward to lower them.

Normally the attachment is lowered to rest directly on the ground or gauge wheels and allowed to follow, or float, over the ground contours (referred to as “flotation”). For best flotation, push the lever forward until attachment reaches the ground and hold it for several seconds until all weight is removed from the tool bars and lifting cables are slack.

10.Auxiliary control lever (Fig. 3-6)this lever is for control of the hydraulic cylinder mounted on some optional attachments. Use of lever varies with each
