WARNING: Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Failure to follow these instructions can result in serious personal injury or property damage.

3.Clean around the oil dipstick or oil fill tube (whichever applies) to prevent dirt from falling into the crankcase.

4.On engines with an oil fill tube, remove the fill cap and add oil (if required) until it reaches the top of the fill tube. Reinstall the fill cap.

5.On engines with a dipstick, remove it and wipe it clean. Reinsert the dipstick, tighten it securely, and remove it. Add oil as needed to bring the level up to the FULL mark. Wipe dipstick clean each time oil level is checked. Do not overfill. Tighten dipstick securely.

B. To Change the Engine Oil:

Change the engine oil as instructed in the Engine Owner’s Manual.

SPARK PLUG SERVICE

Inspect and clean or replace the spark plug after every 100 operating hours or annual- ly. Refer to the Engine Owner’s Manual for spark plug service instructions.

In some areas, local law requires using re- sistor spark plugs to suppress ignition sig- nals. If the engine was originally equipped with a resistor spark plug, use the same type for replacement.

SPARK ARRESTER SCREEN SERVICE

If the engine muffler is equipped with a spark arrester screen, remove and clean it according to the service intervals and in- structions in the Engine Owner’s Manual.

THROTTLE LEVER ADJUSTMENT

If the engine does not respond to various throttle lever settings, refer to the Engine Owner’s Manual for service information or contact your local authorized engine deal- er.

WARNING: Operators shall not tamper with the engine governor settings on the machine; the governor controls the maximum safe operating speed to protect the engine and all moving parts from damage caused by overspeed. Authorized service shall be sought if a problem exists.

CARBURETOR/GOVERNOR CONTROL ADJUSTMENTS

The carburetor was adjusted at the factory for best operating speed. Refer to the En- gine Owner’s Manual for any adjustment information or see your authorized engine dealer.

The governor controls the maximum safe operating speed and protects the engine and all moving parts from damage caused by overspeeding. Do not tamper with the engine governor settings.

OFF-SEASON STORAGE

When the tiller won’t be used for an ex- tended period, prepare it for storage as fol- lows:

1.Clean the tiller and engine.

2.Do routine tiller lubrication and check for loose parts and hardware.

3.Protect the engine and perform recom- mended engine maintenance by following the storage instructions found in the En- gine Owner’s Manual. Be sure to protect the fuel lines, carburetor and fuel tank from gum deposits by removing fuel or by treating fuel with a fuel stabilizer (follow engine manufacturer’s recommendations).

4.Store unit in a clean, dry area.

5.Never store the tiller with fuel in the fuel tank in an enclosed area where gas fumes could reach an open flame or spark, or where ignition sources are present (space heaters, hot water heaters, furnaces, etc.).

634F, 630C, 634A specifications

The Troy-Bilt line of tillers, specifically the 634A, 630C, and 634F models, represents a blend of reliability, power, and advanced engineering designed to meet the needs of avid gardeners and professional landscapers alike. Each model boasts unique features and technologies that enhance performance and usability.

The Troy-Bilt 634A is equipped with a 6.5 HP engine, providing ample power for tackling tough soil conditions. The tiller's 16-inch tilling width allows for efficient breaking up of soil, while its impressive tilling depth of up to 8 inches ensures that garden beds are adequately prepared for planting. The 634A model features a lightweight design, making it easy to maneuver around flower beds and garden rows. Additionally, the adjustable handlebar enhances comfort during operation, accommodating various user heights.

In contrast, the Troy-Bilt 630C offers a slightly different approach. This model is designed for those who seek enhanced control and precision while tilling. It features a 6.75 HP engine and similar tilling capabilities but adds an innovative counter-rotating tilling technology. This feature is particularly useful for breaking up compacted soil and mixing in organic materials, resulting in a well-aerated and fertile garden bed. The 630C also comes equipped with a variety of attachments, allowing users to expand its functionality for different gardening tasks.

The 634F model elevates the line further with its robust frame and advanced features. With a powerful 7 HP engine, it provides optimal performance for larger plots of land. The 634F is designed with a wider tilling width of 18 inches, making it perfect for larger gardens and landscaping projects. Its self-propelled system allows for effortless movement across various terrains, reducing user fatigue. Additionally, the 634F includes a unique automatic depth adjustment feature, enabling gardeners to achieve the desired tilling depth without constant manual adjustments.

Across all three models, Troy-Bilt's commitment to user-friendly design shines through. Features such as easy-to-access controls, durable construction, and stable wheels enhance overall usability. The patented "Forward and Reverse" operating system found in these tillers ensures that gardeners can navigate easily in tight spaces, making them versatile for any gardening situation. The combination of power, advanced technology, and user-focused design makes the Troy-Bilt 634A, 630C, and 634F top choices for those looking to cultivate their garden with ease and efficiency.
