MASSEY-HARRIS 25 ENGINE
The Massey-Harris 25 tractor features a robust 5.7L 4-cylinder gasoline engine, providing substantial power for various agricultural tasks. With a fuel tank capacity of 24 gallons, it offers enhanced operational range, while the auxiliary fuel tank adds convenience for extended use without frequent refueling. However, gasoline engines typically experience lower fuel efficiency compared to diesel, potentially resulting in increased operational costs during prolonged tasks.

TRANSMISSION
The Massey-Harris 25 tractor features a 3-speed forward gearbox with 1 reverse, providing adequate versatility for various farming tasks within moderate speed ranges. Its dry disc clutch system offers reliable disengagement but can experience wear under heavy use, necessitating regular maintenance to ensure optimal performance. This tractor is well-suited for light to medium-duty applications, particularly in smaller agricultural operations or for hobby farming.

MECHANICAL
The Massey-Harris 25 features a 4x2 2WD chassis, which limits traction on loose or uneven terrain compared to a 4WD setup, but enhances fuel efficiency on flat, solid surfaces. Its manual steering allows for greater control in straightforward applications but can become cumbersome in tight spaces. The 3-speed gear transmission provides basic versatility for light tasks, though it may lack the range and responsiveness needed for more demanding agricultural operations.

MASSEY-HARRIS 25 TIRES
The Massey-Harris 25 tractor features robust steel agriculture wheels, with a front tire size of 30x6 inches and a rear size of 48x12 inches, enhancing durability and traction on various terrain types. The larger rear tires provide improved stability and load-bearing capacity, making it suitable for heavier agricultural implements. However, the steel construction may limit weight redistribution capabilities and ride comfort compared to rubber options, thereby impacting performance on softer soils.
