Operation. Troy-Bilt 41AD254X966 | Manualzz




Keep all body parts (hands, feet, face, etc.) away from moving blades. Contact with moving blades will result in serious personal injury.

WARNING: Always wear appropriate eye, hearing, hand, foot and body protection to reduce the risk of injury when operating this unit. Wear head protection. Use a full face shield when needed. Refer to the Safety section for appropriate safety equipment information.


To prevent serious personal injury, avoid arm contact with the engine while operating the unit. The engine may be extremely hot.

• Stand in the operating position (Fig. 17). Stand up straight. Do not bend over.

• Keep feet apart and firmly planted.

• Hold the shaft grip with the right hand. Keep the right arm slightly bent.

• Hold the handle with the left hand. Keep the left arm straight.

• Hold the unit at waist level.

• Position the cutting head / blade a few inches above the ground.


This unit is equipped with a bump head. Trimming line can be released from the cutting head without stopping the engine.

To release more line, lightly tap the bump knob on the ground (Fig. 18) while operating the unit at high speed. For best results, tap the bump knob on bare ground or hard soil. Attempting to release line in tall grass may stall the engine.

NOTE: Do not rest the cutting head on the ground while the unit is running.

Each time the bump knob is tapped, about 1.5 inches (38 mm) of trimming line is released.

NOTE: Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter.

A blade in the cutting head shield will cut the line to the proper length if any excess line is released.

WARNING: Do not remove or alter the line cutting blade assembly. Excessive line length will make the unit overheat. This may lead to serious personal injury or damage to the unit.


• For most operations, cut from side to side.

• To direct clippings away from the operator, tilt the cutting head slightly down to the right; cut from left to right whenever possible.

• Cut tall grass (over 8 inches (20cm)) from the top down by lowering the cutting head onto the grass.

• Cut with the tip of the trimming line.

• Cut in small increments. Move slowly. Do not force the unit.

• Do not trim wet grass or weeds.

NOTE: Some line breakage will occur from:

• Entanglement with foreign matter

• Normal line fatigue

• Attempting to cut thick vegetation

• Forcing the line into objects such as walls or fence posts


When trimming around trees, posts, fences, etc., rotate the whole unit so that the cutting head is at a 30° angle to the ground (Fig. 19).

The trimmer attachment can be used for edging (Fig. 20). Alternatively, a bladed lawn edger attachment can also be purchased for use with this unit.

Rotating the Trimmer Attachment

WARNING: To avoid serious personal injury and damage to the unit, shut the unit off before rotating the attachment.

When edging around sidewalks, flowerbeds, etc., rotate the trimmer attachment 90° inside the coupler. DO NOT rotate the entire unit 90°.

1. Turn the knob counterclockwise to loosen the coupler (Fig. 21).

2. Press and hold the release button (Fig. 21).

3. Rotate the attachment until the release button snaps firmly into the 90° edging hole (Fig. 21).

4. Turn the knob clockwise to tighten the coupler (Fig. 21).

WARNING: Only snap the release button into the 90° edging hole when edging with the trimmer attachment.

Using the 90° edging hole with other attachments could lead to personal injury or damage to the unit.

Maintaining the Trimming Line

Hard surfaces, such as sidewalks, can cause the trimming line to wear down quickly or break.

• Frequently check and adjust the trimming line length. Refer to

Adjusting the Trimming Line Length. Always keep the trimming line fully extended.

DO NOT force the unit. Make shallow cuts in as many passes as are necessary to achieve the desired depth. Cut at a slow, even pace.

WARNING: To avoid serious injury to the operator or others, do not use the blade as an edger.

• Keep the blade parallel to the ground.

• Always cut with the unit running at full speed. This provides maximum cutting power and makes the blade less likely to bind, stall or cause blade thrust.

WARNING: Blade thrust can occur when the spinning blade contacts an object that it does not immediately cut.

Blade thrust can be violent enough to cause the unit and/or operator to be propelled in any direction and possibly lose control of the unit. Blade thrust can occur without warning if the blade snags, stalls or binds. This is more likely to occur in areas where it is difficult to see the material being cut.

• To direct clippings away from the operator, cut from left to right whenever possible.

• Always release the throttle control and allow the unit to idle when not cutting.

• When finished, always unsnap the shoulder strap from the unit before taking off the shoulder strap.

• Never use a dull blade. If the blade becomes dull, refer to

Maintaining the Blade in the Maintenance section.

WARNING: The blade will continue to spin for a while after the unit is turned off. To avoid serious personal injury, do not touch a coasting blade.

WARNING: To avoid serious personal injury, always turn the unit off before removing debris from the unit. Allow the blade to come to a complete stop.
