National Mower 99500500-8400 manual Starting the Engine, Driving the Tractor, Mowing Operation

Page 11

5.Before leaving the mower, always lower wing mowers so that when exiting the mower and stepping on the non-skid pads of the wing mowers, it will not put excessive strain on the lift mechanism.

6.Operate at speeds which allow you to have complete control of the tractor and allow you to stop the tractor or maneuver safely in case of an emergency. It is recommended that you adjust the Speed Control (7, Figure 1) to maintain a constant pedal position/speed and reduce the operator fatigue.

7.To obtain maximum mower life, the operator must use discretion when mowing near gravel areas (roadway, parking areas, cart paths etc.). By operating too close to overlapping gravel areas, stones maybe picked up by the mower and forced between bedknife and reel, causing wear and serious damage to the cutting unit.

STARTING THE ENGINE

Figure 4

1.Open the fuel tank shut off valve (1, Figure 4) (located by the fuel tank) on the fuel line by turning knob counterclockwise.

2.Sit in operator’s seat.

3.Place reel control switch in the “Off” position.

4.Place the traction pedal in “Neutral” position.

5.Pull choke control out and move throttle control lever to mid position.

6.Engage parking brake.

7.Insert ignition key, turn clockwise to “start” position, and release key when engine starts. Do not hold key in “start” position for more than 30 seconds or damage to the starter may result. If engine does not start within this time, release the key and wait for a few minutes before trying again.

8.Push choke control in as engine warms up (or immediately if engine is warm).

DRIVING THE TRACTOR

1.Position throttle at full throttle or slightly less for optimum power and reel speed.

2.Release parking brake (9, Figure 1).

3.Moving forward: Push the toe of the traction pedal forward with the ball of your foot to increase the forward speed.

4.Moving backward: Push the heel of the traction pedal in with the heel of your foot to increase the reverse speed.

5.To return traction pedal to neutral, rock pedal with foot until pedal stops. The pedal will stay in neutral when you remove your foot.

DANGER: To avoid possible loss of control and/or serious bodily injury, avoid abrupt changes in the traction pedal position. Reduce speed on slopes, rough terrain, and in sharp turns to prevent tipping or loss of control.

MOWING OPERATION

1.Check the turf area for debris that would cause damage to the reels. Never operate the mowers when they are not cutting grass, as excessive friction and heat will develop between the bedknife and reel, which will damage the cutting edge.

2.When cutting large areas, the most satisfactory method is to first cut the outer area and then mow clockwise toward the center. The next time you cut, it is advised that you mow in the opposite direction to prevent grass matting.

3.Cutting speeds are governed by conditions of turf, type of terrain, and obstacles to be encountered. Operate tractor at slow speeds when turning.
