  1. Engine Manufacturer: The heart of the John Deere D105 is a robust engine crafted by Briggs & Stratton, a company renowned for its high-quality engines in the lawn and garden industry. Briggs & Stratton engines are well-regarded for their durability, performance, and reliability, making them an ideal match for John Deere’s lawn tractors.
  1. Engine Type: This particular model is equipped with a single-cylinder, four-stroke, air-cooled engine. The single-cylinder design ensures simplicity and efficiency, while the four-stroke cycle offers a smooth and quiet operation. The air-cooled mechanism keeps the engine running at optimal temperatures, preventing overheating during extensive use.
  1. Power Output: With a power output of 17.5 horsepower, this engine provides ample strength for various lawn maintenance tasks. Whether it’s cutting thick grass or navigating hilly terrains, the 17.5 horsepower engine ensures the D105 has the necessary power to handle the demands of residential lawn care without faltering.
  1. Displacement: The engine boasts a displacement of 500 cubic centimeters (cc). This measurement indicates the volume of the cylinder, highlighting the engine’s capacity to generate power. A 500 cc displacement strikes a balance between fuel efficiency and the ability to deliver substantial power for lawn mowing tasks.
  1. Fuel Capacity: The D105 is designed with a fuel tank that can hold up to 2.4 gallons of fuel. This generous capacity allows for extended mowing sessions without the need for frequent refueling, enhancing the convenience for the user. It ensures that homeowners can focus on their lawn care tasks without constant interruptions, making lawn maintenance more efficient and enjoyable.

  1. Battery: The battery configuration in the John Deere D105 Lawn Tractor plays a crucial role in ensuring the machine’s operational readiness and reliability. The tractor is equipped with a single 12-volt battery, a standard in the industry for residential lawn tractors due to its ability to provide sufficient power for starting the engine and powering electrical components. This 12-volt system is designed to offer a balance between ample cranking power for the engine’s starter and the electrical demands of the tractor’s ignition system, lights, and any additional accessories that may be equipped.

Transmission Specifications of the John Deere D105 Lawn Tractor

  1. Transmission Type: The D105 is equipped with an automatic transmission, which significantly enhances the user experience by providing a seamless, user-friendly operation. This type of transmission eliminates the need for manual gear shifting, making the tractor easier to operate for users of all skill levels.
  1. Model: The transmission unit employed in the D105 is the General Transmission RT400. This model is known for its reliability and durability, ensuring smooth operation and longevity. The RT400 is specifically designed to handle the demands of lawn care, providing consistent performance and the flexibility needed for various tasks.
  1. Gears: It features infinite forward and reverse speeds, a key advantage for precise control over the tractor’s movement. This capability allows for easy adjustment of speed to match the task at hand, whether navigating tight spaces, maneuvering around obstacles, or adjusting the pace for different lawn conditions. The infinite speeds also contribute to a more efficient mowing experience, enabling the operator to optimize performance according to the specific requirements of the lawn or garden.

The chassis and dimensions of the John Deere D105 Lawn Tractor 

  1. Frame: The D105 features a full-length welded steel frame. This type of frame construction is known for its strength and durability, ensuring the tractor can withstand the demands of regular use while providing a stable platform for mowing and other lawn care tasks.
  1. Front Tires: It is equipped with 15×6-6 front tires. These dimensions indicate a tire that’s 15 inches in diameter, 6 inches wide, designed to fit a 6-inch rim. This size is optimal for providing good maneuverability and minimizing turf damage during turns.
  1. Rear Tires: The rear tires are sized at 20×8-8, meaning they’re 20 inches in diameter, 8 inches wide, and fit an 8-inch rim. Larger and wider than the front tires, they offer increased traction and stability, which is crucial for smooth operation over various types of terrain and slopes.
  1. Wheelbase: The wheelbase, or the distance between the centers of the front and rear wheels, is 48.9 inches. A longer wheelbase contributes to better stability and ride comfort, especially when operating over uneven ground.
  1. Length: The overall length of the tractor is 68.75 inches. This compact size allows for easy storage in a garage or shed, while still being long enough to ensure stability during use.
  1. Width: With a width of 51.75 inches when the mower deck is attached, the D105 is wide enough to offer a significant cutting path, reducing the time needed to mow a lawn, yet narrow enough to navigate through typical garden gates and between obstacles in the yard.
  1. Height: Standing at 42.5 inches tall, the tractor has a relatively low profile, which aids in lowering the center of gravity for enhanced stability. It’s also beneficial for maneuvering under tree branches and other overhead obstacles.
  1. Weight: Weighing in at 442 lbs, the D105 is designed to be heavy enough to ensure good traction and handling, yet light enough for ease of maneuverability and to minimize pressure on the lawn, helping to prevent compaction and damage to the turf.


  1. Mower Deck Width: The D105 is equipped with a 42-inch wide mower deck, a sizable width that strikes an ideal balance between covering a large area quickly and being agile enough to maneuver around obstacles and through garden gates. This width is conducive to maintaining medium-sized lawns efficiently, reducing the number of passes needed to complete the mowing task.
  1. Cutting Height: The cutting height can be adjusted from 1 inch to 4 inches in ¼-inch increments. This feature allows for precise control over the lawn’s appearance, enabling the user to achieve the desired grass length based on the season or personal preference. The wide range of adjustability also makes the D105 adaptable to different types of grass and lawn conditions, from fine lawns to more robust grass varieties.
  1. Mower Deck Lift System: Adjustments to the cutting height are facilitated by a manual lever, a straightforward and reliable mechanism that ensures ease of use. This manual lever allows for quick adjustments on the go, providing flexibility to adapt to varying lawn conditions without the need for complex procedures or tools.
  1. Blades: The mower deck houses two blades, a configuration that enhances the cutting efficiency and quality. Dual blades ensure a cleaner cut, as they can better distribute the grass clippings over the lawn or into a collection system if equipped. This setup is also beneficial for mulching, as it can more effectively chop the grass into fine pieces, which then decompose more quickly, providing nutrients back to the soil.

PTO (Power Take-Off) Specifications

  • Operational Type: Independent, a crucial feature that allows the PTO to operate independently of the tractor’s motion, offering versatility in how attachments are used and managed.
  • Clutch: Mechanical, ensuring durability and reliability in engaging and disengaging the PTO, a key aspect for the smooth operation of various attachments.
  • Speed: 3000 rpm, indicating the power output available for attachments, enhancing the tractor’s utility for a wide range of tasks.

Attachments Compatibility

  • Versatility is a key component of the D105’s design, as evidenced by its compatibility with a range of attachments. Owners can enhance the functionality of their tractor with options like a 46-inch front blade and a 44-inch front-mount snow blower, among others. This compatibility extends the utility of the D105 beyond traditional lawn mowing, allowing it to be used for tasks such as snow removal and landscape grading, thus offering year-round serviceability.

Compact Design

  • The compact design of the D105 makes it especially maneuverable in tight spaces, a crucial feature for residential properties with complex landscapes or limited storage space. Its design optimizes the balance between size and performance, ensuring that while it is powerful enough to handle various lawn care tasks, it remains easy to navigate through garden paths, around trees, and between flower beds. This maneuverability, combined with its efficient design, makes the D105 an ideal choice for homeowners seeking a practical and effective solution for their lawn maintenance needs.
