ENGINES OVERVIEW
The McCormick-Deering W-6 tractor features a robust International Harvester 4.1L 4-cylinder engine, capable of running on both distillate and gasoline, offering versatility in fuel options for various applications. Key advantages include its moderate horsepower for general farming tasks and reliability in different operating conditions. However, users may encounter challenges with engine efficiency when switching fuels, particularly if not adjusted properly, affecting overall performance in demanding scenarios.

ENGINE DETAIL 1
The McCormick-Deering W-6 features a robust 4-cylinder distillate engine with a relatively low compression ratio of 4.75:1 for gasoline and 4.5:1 for kerosene, enhancing fuel versatility but limiting power output compared to higher-compression counterparts. The oil bath air cleaner contributes to better filtration, making it suitable for agricultural environments, although it requires regular maintenance to prevent clogging. With a rated RPM of 1450, this tractor provides efficient torque for heavy-duty applications, but its relatively low RPM may limit speed on open terrains.

ENGINE DETAIL 2
The McCormick-Deering W-6, featuring a 247.7 ci (4.1L) 4-cylinder gasoline engine, excels in mid-range power delivery with a low compression ratio of 5.65:1, optimizing fuel efficiency for agricultural tasks. Its oil bath air cleaner enhances durability by minimizing filter maintenance, particularly in dusty environments. Operating at a rated RPM of 1450, the W-6 is well-suited for heavy-duty applications, though its relatively low power output at this RPM may limit performance for more demanding tasks compared to higher RPM counterparts.

MECHANICAL
The McCormick-Deering W-6 tractor features a 4x2 2WD chassis, providing good maneuverability for light- to medium-duty agricultural tasks but may struggle in muddy or hilly terrains due to lack of traction. The manual steering system offers a straightforward operation, yet requires physical effort, especially in tight turns. With a 5-speed sliding gear transmission, operators benefit from versatile speed selection, enhancing productivity for varied applications but may find gear shifting less smooth compared to modern synchro transmissions.

MCCORMICK-DEERING W-6 TIRES
The McCormick-Deering W-6, equipped with 6.00-16 front tires and 13-30 rear tires, offers excellent traction and stability for various agricultural tasks. The larger rear tires enhance weight distribution and improve field performance, particularly in uneven terrain, while the front tires provide adequate steering control. However, the narrower 6.00-16 front tires may limit its maneuverability in tighter spaces, making it more suitable for larger fields and open areas.
