ENGINES OVERVIEW
The Farmall 504 tractor is offered with different engine options, including a robust 3.1L 4-cylinder diesel for enhanced torque and fuel efficiency, making it ideal for heavy-duty agricultural tasks. In contrast, the 2.5L 4-cylinder gasoline and LP gas engines provide lower initial costs and simpler maintenance, but may lack the diesel engine's power under continuous load. Choosing between these engine types depends on the operational need; the diesel variant excels in farm operations requiring high power, while gasoline and LP options are preferable for lighter tasks and easier serviceability.

ENGINE DETAIL 1
The Farmall 504 is powered by a D-188 diesel engine, featuring a displacement of 3.1L and a high compression ratio of 18.7:1, which contributes to fuel efficiency and torque but may increase the risk of engine knocking if improperly maintained. Its relatively moderate rated RPM of 2200 and low idle range (900-2200 RPM) enhance its versatility for various farming tasks while providing a stable power profile. The oil bath air cleaner offers improved filtration, though it may require more frequent maintenance compared to dry filters, impacting operational downtime.

ENGINE DETAIL 2
The Farmall 504 features a C153 gasoline engine with a moderate 152.1 ci displacement, providing sufficient power for a variety of farming tasks, but its lower compression ratio of 7.70:1 may limit efficiency and power output under load. The engine's rated RPM of 2200 allows for adequate operational speed, making it suitable for cultivating and transport duties but may present challenges during high-demand activities. Additionally, the 5-quart oil and 15-quart coolant capacities indicate a simple maintenance schedule, yet vigilance is required to prevent overheating during prolonged use.

ENGINE DETAIL 3
The Farmall 504 tractor features a 4-cylinder LP gas engine with a displacement of 152.1 ci (2.5L), offering a balance between power and fuel efficiency at a rated RPM of 2200. Its oil bath air cleaner enhances filtration, resulting in improved engine longevity, while the 5-quart oil capacity and 16-quart coolant capacity provide adequate lubrication and cooling for extended operations. Notably, the tractor's LP gas system can reduce emissions and fuel costs but may present challenges in availability and infrastructure in certain areas.

FARMALL 504 ENGINES
The Farmall 504 tractor is equipped with options for three engine types: a robust 3.1L 4-cylinder diesel, a 2.5L 4-cylinder gasoline, and a 2.5L 4-cylinder LP gas. The diesel variant offers higher torque and fuel efficiency, making it ideal for heavy-duty applications, while the gasoline and LP models provide easier starting in cold conditions. However, the diesel's higher maintenance costs and the weight disadvantage may limit its utility in lighter tasks compared to the gasoline counterparts.

TRANSMISSIONS OVERVIEW
The Farmall 504 features a 5-speed unsynchronized gear and a 10-speed two-speed power shift system, offering versatile gear options for varying field conditions. The unsynchronized gears require precise shifting, which can be less user-friendly for inexperienced operators, whereas the power shift enables smoother transitions between speeds without clutching—enhancing operational efficiency. For optimal performance, it's recommended to assess load conditions and adjust gear selections accordingly to prevent undue stress on the transmission system.

TRANSMISSION 1
The Farmall 504 features an unsynchronized transmission with 5 forward and 1 reverse gear, which can lead to challenging shifts under load, particularly for inexperienced operators. The 267mm dry disc clutch provides adequate disengagement for agricultural applications but may require more frequent maintenance compared to hydraulic clutches, especially under heavy use. This combination is ideal for light to medium-duty farming tasks, where operator skill can optimize gear changes.

TRANSMISSION 2
The Farmall 504 tractor features a two-speed power shift transmission with 10 forward and 2 reverse gears, enhancing productivity by allowing quicker gear changes without stopping. The torque amplifier provides additional torque under load, beneficial for heavy-duty tasks like plowing or hauling. However, the dry disc clutch may require more maintenance compared to hydraulic alternatives, and users should monitor wear to ensure optimal performance.

FARMALL 504 TIRES
The Farmall 504 tractor features a front tire size of 6.00-16 and rear tire size of 12.4-38, providing good traction and stability for varied field operations. Its tire configuration is advantageous for cultivating and tilling on uneven terrain, but the relatively narrow front tires may limit steering precision in tight spaces. Consider a scenario where steep inclines or heavy mud is encountered; the rear tire's larger diameter can enhance performance, though operators should be cautious of potential rollover risks.

DIMENSIONS & TIRES
The Farmall 504 tractor offers two wheelbase configurations (90 inches for tricycle and 96 inches for wide-front), enhancing stability and maneuverability based on the farming scenario. Weighing 5,430 lbs, it provides substantial ground contact, reducing tire slippage during tilling or heavy-duty tasks. However, the narrower tricycle setup may be less stable on uneven terrain, making the wider front preferable for applications requiring improved load distribution and traction.
