Older versions may lack features like adjustable handles or improved spool systems found in the GH600.
This manual specifically addresses the GH600; however, many instructions are broadly applicable. Always refer to model-specific labeling and diagrams for precise component identification and operation.

Safety First: Important Precautions
Prioritize safety! Always read all instructions carefully before operating your Grass Hog. Protective gear is essential, and awareness of surroundings is crucial for safe use.
General Safety Warnings
Read carefully before use! This power tool is capable of causing serious injury if not operated correctly. Always disconnect the power source before making any adjustments or changing accessories. Never operate the Grass Hog in wet conditions or near flammable materials. Keep bystanders, especially children and pets, a safe distance away from the work area.
Inspect the cord regularly for damage and replace if necessary. Avoid using extension cords unless absolutely required, and ensure they are properly rated for outdoor use. Never carry the tool by the cord or yank it to disconnect from the power outlet. Maintain a firm grip on the handles at all times during operation.
Specific Safety Instructions for the Grass Hog
Prioritize your safety! Always ensure the rotating blade has completely stopped before setting the Grass Hog down or attempting any maintenance. Never reach under the cutting deck while the motor is running. Be mindful of hidden objects like rocks or debris that could be thrown by the blade.
Avoid operating on steep slopes to maintain control and prevent rollovers. Regularly check blade sharpness and replace dull blades immediately.

Operating Instructions
Beginner-friendly operation is key! Follow these steps for safe and effective trimming; mastering your Black & Decker Grass Hog is now within reach.
Starting the Grass Hog
Before you begin, ensure the cutting head is clear of obstructions. Connect the Grass Hog to a properly grounded extension cord, suitable for outdoor use, and verify the power switch is in the ‘off’ position. Depress the safety lock button and simultaneously squeeze the trigger to initiate operation.
If the motor doesn’t start, double-check the extension cord connection and ensure the safety lock is fully engaged before attempting again. Avoid continuous trigger squeezing; use short bursts for controlled operation. Always maintain a firm grip and be aware of your surroundings during startup and operation for optimal safety.
Proper Cutting Techniques
For optimal results, utilize a sweeping motion, slightly overlapping each pass to avoid leaving uncut patches. Maintain a consistent walking speed, allowing the Grass Hog to efficiently trim the grass. Avoid forcing the unit; let the blades do the work. When encountering thicker patches, reduce your walking speed and make multiple passes.
Always cut across slopes, never up and down, to prevent loss of control. Be mindful of debris and obstacles, and adjust your technique accordingly. Regularly inspect the cutting head for buildup and clear any obstructions to maintain peak performance and a clean cut.
Adjusting Cutting Height
The Grass Hog GH600 features easy-to-use height adjustment settings, typically controlled by levers or dials near the wheels. Before starting, select your desired cutting height based on grass length and preference. Lower settings provide a closer cut, while higher settings are suitable for longer grass or uneven terrain.
Always ensure all wheels are set to the same height to maintain an even cut. Periodically check the settings during use, as bumps or obstacles can sometimes shift them. Refer to the diagram in the manual for specific adjustment instructions for your model.

Maintenance and Care
Prolong your Grass Hog’s life with routine cleaning, blade upkeep, and motor checks – essential for peak performance and lasting durability!
Cleaning After Each Use
Maintaining a clean Grass Hog is crucial for optimal performance and longevity. After every use, always disconnect the power source before beginning any cleaning procedures. Remove any accumulated grass clippings from the cutting head and surrounding areas using a brush or scraper – avoid using water directly on the motor or electrical components.
Inspect the blade for damage or debris and clean accordingly. Wipe down the exterior housing with a damp cloth. Regularly check the cord for any signs of wear or damage, and address them promptly. Proper cleaning prevents build-up, ensuring efficient operation and extending the life of your Grass Hog.
Blade Sharpening and Replacement
A sharp blade ensures a clean cut and reduces strain on the motor. Regularly inspect the blade for dullness or damage. Sharpening can be done with a metal file, following the original bevel angle – exercise extreme caution! If the blade is severely damaged, or excessively worn, it must be replaced.
Always disconnect the power before handling the blade. Replacement blades are readily available; refer to the ‘Parts & Accessories’ section for compatible options. Ensure the new blade is securely fastened before operation. A dull or damaged blade compromises cutting performance and safety.
Motor Maintenance
Prolonging your Grass Hog’s life requires minimal motor maintenance. Regularly remove grass clippings and debris from the motor housing vents to prevent overheating. Never attempt to lubricate the motor yourself; this can cause damage and void the warranty.
Inspect the power cord for any signs of damage – fraying or cuts – and replace it immediately if found. Store the Grass Hog in a dry location to protect the motor from moisture. Proper ventilation and storage are key to optimal motor performance and longevity.

Troubleshooting Common Issues
Facing problems? This section provides solutions for typical Grass Hog issues like starting failures, vibrations, and uneven cuts, ensuring smooth operation quickly.
Grass Hog Won’t Start
Is your Grass Hog refusing to power on? First, verify the power cord is securely connected to both the trimmer and a functioning outlet. Check the outlet itself with another device to confirm it’s delivering power. Inspect the cord for any visible damage – cuts or fraying – and do not use if compromised.
Next, ensure the safety lock-off button is fully engaged. The Grass Hog requires this to be held down while pressing the trigger. Finally, examine the motor brushes; worn brushes can prevent starting. If these checks don’t resolve the issue, consult a qualified technician.
Excessive Vibration
Experiencing unusual shaking during operation? Excessive vibration often indicates an imbalance in the cutting head. Immediately stop the Grass Hog and disconnect the power. Carefully inspect the blade for damage – nicks, bends, or uneven wear. A damaged blade must be replaced; do not attempt repairs.
Also, ensure the blade is securely fastened. Loose mounting hardware can cause significant vibration. Check all screws and bolts, tightening as needed. If vibration persists with a new, properly installed blade, contact Black & Decker support for further assistance.
Cutting Issues & Uneven Cut
Frustrated with patchy results? An uneven cut typically stems from a dull blade or incorrect cutting height. First, ensure the blade is sharp – a dull blade tears grass instead of cleanly cutting it. Adjust the cutting height to suit your lawn’s conditions; avoid scalping.
Also, maintain a consistent walking pace. Moving too quickly can overwhelm the motor, leading to an uneven finish. Overlapping each pass slightly ensures complete coverage and a professional-looking lawn. Regularly clean the underside of the guard to prevent buildup.

Advanced Features & Techniques
Master your lawn! Explore edging, tight-space cutting, and tackling thick or wet grass with the Grass Hog – maximizing its versatility and power.
Edging with the Grass Hog
Achieve professional-looking edges effortlessly! The Black & Decker Grass Hog excels at defining borders along sidewalks, driveways, and flowerbeds. Tilt the trimmer head vertically, using the edge guide if equipped, for a clean, precise cut.
Maintain a steady pace and avoid pressing too hard, allowing the blade to do the work. For thicker grass or stubborn edges, make multiple passes. Remember to always wear appropriate safety gear, including eye protection, when edging. Regularly inspect the blade for damage and ensure it’s properly secured for optimal performance and safety during edging tasks.
Cutting in Tight Spaces
Navigate challenging areas with ease! The Grass Hog’s lightweight design and maneuverability make it ideal for trimming around obstacles like trees, shrubs, and garden furniture. Utilize short, controlled sweeps, angling the trimmer head to reach under and around objects effectively.
Avoid forcing the trimmer into confined spaces; instead, reposition yourself for a clearer approach. Regularly clear away cut grass to maintain visibility and prevent clogging. Prioritize safety by being mindful of your surroundings and keeping hands and feet clear of the cutting path when working in tight spaces.
Dealing with Thick or Wet Grass
Conquer challenging conditions! When encountering thick or wet grass, reduce your walking speed and take smaller, overlapping passes. This prevents bogging down and ensures a cleaner cut. Raise the cutting height slightly to avoid straining the motor and potential clogging.
Frequently clear accumulated clippings from the trimmer head. Avoid operating in excessively wet conditions, as this poses an electrical hazard and reduces cutting efficiency. Allow grass to dry before trimming for optimal results and to prolong the life of your Grass Hog.

Parts & Accessories
Enhance your Grass Hog! Discover genuine replacement blades, convenient spool options, and valuable accessories designed to maximize performance and extend its lifespan.
Replacement Blades
Maintaining optimal cutting performance relies heavily on sharp, undamaged blades. Regularly inspect your Grass Hog’s blades for wear, nicks, or bending. Dull blades tear grass instead of cutting cleanly, stressing the motor and yielding an unsatisfactory finish. Black & Decker offers a variety of replacement blade options, specifically engineered for compatibility with your GH600 model.
Ensure you select the correct blade type for your grass and intended use. Consider purchasing multiple sets to avoid downtime during peak mowing season. Always disconnect the power source before changing blades, and follow the detailed instructions in the ‘Blade Sharpening and Replacement’ section for safe and effective installation.
Spool Replacements (if applicable)
For Grass Hog models utilizing a spool for line advancement – though the GH600’s spool functionality varies by version – understanding replacement is crucial. Check your specific model’s documentation to confirm spool compatibility. When the line becomes worn or broken, a new spool ensures continued edging and trimming capabilities. Black & Decker provides genuine replacement spools designed for smooth feeding and optimal performance.
Always ensure the Grass Hog is powered off before attempting a spool change. Follow the instructions detailed in your model’s manual for proper installation, avoiding damage to the trimmer head. Using non-genuine spools may void your warranty.
Available Accessories
Enhance your Grass Hog’s versatility with a range of Black & Decker accessories! These include additional replacement blades for varied terrain, extending the tool’s lifespan and maintaining optimal cutting performance. Extension poles are available, allowing for increased reach and reducing strain during use, particularly for larger yards. Protective guards offer enhanced safety, shielding against debris.
Consider battery upgrades (for cordless models) for extended runtime. Explore edging wheels for precise sidewalk and driveway detailing. Always verify accessory compatibility with your specific Grass Hog model before purchase.

Frequently Asked Questions (FAQ)
Get Answers: Find solutions to common queries regarding your Grass Hog, covering weed control, optimal grass types, and accessing further support resources.
Can the Grass Hog handle weeds?
Weed Management: The Black & Decker Grass Hog is primarily designed for trimming grass, but it can tackle smaller, softer weeds effectively, especially when they are young. However, attempting to cut through thick, woody, or established weeds may strain the motor and potentially damage the trimmer head.
For optimal performance, it’s recommended to address weeds before they become overly robust. Regularly trimming around garden beds and along fences will prevent weeds from gaining a strong foothold. Consider using a dedicated weed whacker or herbicide for larger, more persistent weed infestations to prolong the life of your Grass Hog.
What type of grass is best suited for the Grass Hog?
Grass Compatibility: The Black & Decker Grass Hog excels at maintaining common lawn grasses like Kentucky Bluegrass, Fescue, and Ryegrass. It’s particularly effective on grass that hasn’t been allowed to grow excessively long or become overly dense.
While it can handle St. Augustine and Zoysia grass, these thicker varieties may require more frequent trimming and potentially slower cutting speeds. Avoid using the Grass Hog on very tall, coarse grasses, as this can overload the motor. Regular maintenance and appropriate cutting techniques will ensure optimal results for various grass types.
