ENGINE DETAIL
The Massey-Harris 30, powered by a Continental F162 engine, offers a 162.4 ci (2.7 L) displacement and a relatively low compression ratio of 6.1:1, which contributes to lower power output but enhances reliability and longevity at rated RPM of 1800. Its liquid-cooled system with a coolant capacity of 12 quarts (11.4 L) aids in maintaining optimal engine temperature, reducing the risk of overheating during prolonged use. However, the 6-volt starter may pose starting challenges in colder climates, demanding a reliable battery and maintenance for consistent performance.

MASSEY-HARRIS 30 ENGINE
The Massey-Harris 30 features a Continental 2.7L 4-cylinder gasoline engine, providing a balance of efficiency and power for light to medium agricultural tasks. With a fuel tank capacity of 20 gallons (75.7 L), it offers extended operational time, making it suitable for longer field work without frequent refueling. However, the gasoline engine may not deliver the same torque as diesel counterparts, possibly limiting its performance in heavy-duty applications.

TRANSMISSION
The Massey-Harris 30 tractor features a simple 5-speed forward and 1-reverse gear system, facilitating moderate speed control suitable for various farming tasks. The dry disc clutch provides reliable engagement and disengagement, but may require more frequent maintenance compared to wet clutches, especially under heavy-duty conditions. Overall, this tractor is advantageous for small to medium-scale operations, but operators should anticipate potential wear on the clutch with continuous use.

MECHANICAL
The Massey-Harris 30 tractor features a 4x2 2WD chassis, which may limit traction on uneven terrain but allows for simpler mechanical design and maintenance. Its manual steering and mechanical brakes could pose challenges in user-friendliness and stopping power, especially in demanding conditions. The 5-speed transmission offers versatility for various tasks, making it suitable for light agricultural operations, yet potentially lacking in speed ranges required for more extensive farming needs.

MASSEY-HARRIS 30 TIRES
The Massey-Harris 30 tractor features a front tire size of 5.00-15 and a rear size of 10-38, which facilitates optimized traction and stability on varied terrains. The narrower front tires may improve maneuverability in tight spaces, while the larger rear tires enhance pull strength and load capacity, ideal for agricultural applications. However, operators should be cautious of turf damage in softer ground conditions due to the rear tire's width.

DIMENSIONS & TIRES
The Massey-Harris 30 tractor, with an 84.5-inch wheelbase, offers a compact design that enhances maneuverability in tight fields but may limit stability under heavy loads. Weighing 3,500 lbs provides a balance between ground traction and transportability, though lighter weight may affect implementation of certain heavy-duty implements. The front tire size 5.00-15 coupled with rear tire size 10-38 allows for a favorable power-to-weight ratio, yet the disparity in tire dimensions may lead to uneven wear if not managed properly.
