DAVID BROWN 30 POWER
ENGINES OVERVIEW
The David Brown 30 tractor offers versatility with its 2.7L 4-cylinder engine available in diesel, gasoline, and kerosene fuels, catering to different agricultural needs and fuel availability. The diesel variant provides better fuel efficiency and torque for heavy-duty tasks, while gasoline and kerosene options may reduce operational costs in regions where those fuels are more accessible. However, the engine's limited displacement could struggle with heavy loads, making careful load management crucial for optimal performance.

ENGINE DETAIL 1
The David Brown 30 tractor, with its 165.1 ci (2.7 L) 4-cylinder liquid-cooled diesel engine, offers a power output of 34 hp (25.4 kW) at a rated RPM of 2000, making it suitable for light to medium-duty agricultural tasks. The bore and stroke dimensions of 3.625x4.00 inches (92 x 102 mm) indicate a long-stroke design, which typically enhances low-end torque, ideal for plowing and tilling. However, its comparatively lower horsepower may limit its efficiency in more demanding applications, such as heavy hauling or hillside operations.

ENGINE DETAIL 2
The David Brown 30 tractor features a 4-cylinder, gasoline engine with a displacement of 165.1 cubic inches (2.7 L) and a bore/stroke of 3.625x4.00 inches, which allows for efficient combustion and reliable torque delivery. Producing 41 hp at a rated RPM of 2300, it offers a balance of power suitable for small to mid-scale agricultural tasks, but may face challenges with fuel efficiency and higher operating costs compared to diesel alternatives. Ideal for hobby farmers and light-duty applications, this model provides good maneuverability and ease of use in penned or small-field operations.

DAVID BROWN 30 ENGINES
The David Brown 30 tractor features a versatile 2.7L 4-cylinder engine available in diesel, gasoline, and kerosene variants, allowing for adaptability in fuel sourcing based on availability and cost. With a fuel tank capacity of 12.7 gallons (48.1 L) and an auxiliary fuel tank of 1.8 gallons (6.8 L), it provides reasonable operational range for agricultural tasks, though the kerosene variant may require additional infrastructure for sourcing and handling. Challenges may arise in maintenance and performance tuning given the differences in fuel properties, which can affect engine efficiency and emissions.

TRANSMISSION
The David Brown 30 features a non-synchromesh gear system, providing 6 forward and 2 reverse gears for versatile operation across various terrains. This configuration offers good torque management for tasks like plowing or hauling, but may require more coordination when shifting gears. Users may find advantages in simplicity and durability, but potential challenges include difficulty in gear engagement under heavy loads.

MECHANICAL
The David Brown 30 features a 4x2 2WD chassis, which provides decent traction on flat terrains but may struggle in muddy or uneven conditions, limiting its versatility. The manual steering and mechanical drum brakes indicate lower maintenance needs, though they require more driver effort and may not offer optimal stopping power compared to modern hydraulic systems. With a 6-speed gear transmission, it facilitates a range of operational speeds, making this tractor suitable for light farming tasks but potentially challenging for heavier work without additional horsepower.

DAVID BROWN 30 TIRES
The David Brown 30 tractor features 6.00-19 front and 11-28/12.4-28 rear agricultural tires, providing a suitable balance of flotation and traction for various field conditions. The choice of tire sizes enhances stability and steering control while also allowing for operation in diverse terrains. A potential challenge is the limited ground clearance due to smaller front tires, which may affect performance in heavy, uneven soil conditions.
