DAVID BROWN CROPMASTER POWER
ENGINE DETAIL
The David Brown Cropmaster features a robust 4-cylinder kerosene engine with a displacement of 2.5L, delivering 25hp at a rated RPM of 2000, making it suitable for small to medium agricultural tasks. Its bore and stroke ratio (3.50x4.00 inches) promotes effective torque at lower speeds, which is advantageous for plowing and tilling operations. However, the limited power output may pose challenges in more demanding applications, such as heavy-duty hauling or lifting.

DAVID BROWN CROPMASTER ENGINE
The David Brown Cropmaster features a 2.5L 4-cylinder kerosene engine, known for its fuel efficiency while delivering adequate power for light to medium agricultural tasks. A notable advantage of the kerosene fuel system is its lower cost and cleaner combustion compared to diesel, although it may result in reduced torque performance. Compatibility with various implements makes the Cropmaster a versatile choice for small to medium farms, but users should be aware of the maintenance requirements associated with older tractor models.

TRANSMISSIONS OVERVIEW
The David Brown Cropmaster tractor offers a choice of either a 4-speed or a 6-speed transmission, allowing for flexible speed control depending on the agricultural task at hand. The 6-speed option provides better torque characteristics and efficiency in diverse field conditions, while the 4-speed may simplify operation for tasks requiring less speed variation. The selection of gearbox can impact overall productivity and operator comfort, particularly in applications involving heavy towing or precise planting operations.

MECHANICAL
The David Brown Cropmaster tractor features a 4x2 2WD chassis, which offers simplicity and ease of maintenance but may limit traction in challenging terrains. With manual steering and mechanical drum brakes, operators should be prepared for potentially heavier steering input and less responsive braking compared to hydraulic systems. The 4-speed and 6-speed gear transmission options provide flexibility for various field tasks, catering to applications requiring different torque and speed settings, yet may necessitate frequent shifting during operations.

DAVID BROWN CROPMASTER TIRES
The David Brown Cropmaster tractor features a 26x5 steel front tire configuration and a substantial 42x10 steel rear tire setup, which enhances stability and traction on varied terrains. The larger rear tires provide improved load-bearing capacity and better flotation in soft soil conditions, making it advantageous for agricultural applications. However, the all-steel construction may increase weight, potentially leading to reduced maneuverability and increased soil compaction during operation.

DIMENSIONS & TIRES
The David Brown Cropmaster's wheelbase of 71.5 inches (181 cm) contributes to its stability during field operations, ideal for maneuvering in tight spaces. Weighing 2950 lbs (1338 kg), it offers a balance between sufficient traction and reduced ground compaction, beneficial for sensitive soil environments. However, the tire sizes (6.00-19 front and 9.00-28 rear) may limit flotation in softer terrains, necessitating consideration for appropriate ground conditions during use.
