What You'll Learn

Fuel tank location varies by tractor model
The fuel tank location varies by tractor model, with most newer tractors having their fuel tanks at the back. For example, the M6040 tractor has its fuel tank under the floorboards on the left-hand side, behind the seat. Similarly, the JD 870 has its fuel tank mounted crossways behind the seat, with the filler near the right fender. The Kubota L Series and most small tractors from Deere have their fuel tanks under the hood. The 3 series JD tractors have their tanks high up behind the seat, while the Grand L models have their tanks low and to the right. Korean-made tractors typically have their tank assembly on the left under the step up, contributing to the center of gravity.
Some older tractor models, such as the IH2500b from the late 1970s, had fuel tanks on the sides under the rear fenders, over and behind the rear axle. This design kept the filling process away from the engine compartment and made the fuel sediment bowl and shutoff valves easily accessible. While this location added ballast over the rear axle, it usually meant a smaller fuel capacity.
The location of the fuel tank on a tractor can impact the convenience of refuelling, with some users expressing a preference for low-mounted tanks for ease of filling and a lower center of gravity. Additionally, the placement of the fuel tank can influence the tractor's overall weight distribution and stability, especially when operating on uneven terrain or off-road conditions.
It's worth noting that the fuel tank location can also affect maintenance and accessibility. Having the fuel tank tucked away under the hood or in a less exposed area may offer advantages by keeping the fuel lines as short as possible. This configuration can also protect the tank from potential damage during operation or when navigating through areas with low clearance or obstacles.
In conclusion, the fuel tank location on a tractor is not standardized and can vary significantly across different models and manufacturers. The design considerations for fuel tank placement involve a balance between functionality, ease of refuelling, weight distribution, and overall tractor performance. Depending on the specific needs and preferences of the operator, the fuel tank location can be a crucial factor in selecting the most suitable tractor model.

Some tanks are under the hood, others are behind the seat
The location of the fuel tank in a tractor varies depending on the make and model. Some tractors have fuel tanks located under the hood, while others have them positioned behind the seat.
Tractors with fuel tanks under the hood include the Kubota L Series and most small tractors from Deere. Having the fuel tank tucked away under the hood keeps the fuel lines as short as possible and protects the tank from damage. However, this location can make refuelling more challenging.
On the other hand, tractors like the M6040 and some 3 series JD tractors have their fuel tanks behind the seat. This location is preferred by some users as it makes refuelling more convenient, especially when using a full five-gallon Jerry can. However, accessing the fuel tank behind the seat may require lifting the fuel can higher during refuelling.
The placement of the fuel tank also affects the tractor's centre of gravity. Low-mounted fuel tanks, such as those found in some Korean-made tractors and the Kubota Tractor Loader L3560, contribute to a lower centre of gravity, which can be advantageous for stability.
Ultimately, the location of the fuel tank in a tractor depends on the design and intended use of the machine. While under-the-hood fuel tanks offer protection and a more compact fuel line, behind-the-seat fuel tanks provide easier access for refuelling and can contribute to a lower centre of gravity.

Tanks can also be found under the floorboards
The location of a tractor's fuel tank varies depending on the make and model of the tractor. While some tractors have fuel tanks located at the back, on the sides, or under the hood, others have their tanks positioned under the floorboards.
For example, the M6040 tractor has its fuel fill located right behind the seat, with the fuel tank situated under the floorboards on the left-hand side. This placement provides easy access to the fuel tank, but it can be challenging to lift a full five-gallon Jerry can to refill the tractor.
Similarly, the JD 870 tractor, which is about 20 years old, has its fuel tank mounted crossways behind the seat, with the filler near the right fender. This design allows for convenient refilling using 6-gallon plastic fuel cans, which can be rested on the fender until they are almost empty before being turned up to empty completely.
Some Korean-made tractors also feature fuel tanks located under the step-up on the left side, contributing to a lower center of gravity. Additionally, the 3 series JD tractors have their tanks positioned high up behind the seat.
While under-floorboard fuel tanks offer advantages such as a lower center of gravity and convenient refilling, they may also present challenges in terms of refuelling ergonomics, especially when using heavy fuel cans.

Tanks contribute to the tractor's centre of gravity
The position of a tractor's fuel tank is important as it contributes to the tractor's centre of gravity, which is a central concept in tractor stability and instability. The centre of gravity (CG) is the point where all parts of the tractor balance one another. For example, when a two-wheel-drive tractor is on level ground, the CG is typically about 10 inches (25.4 cm) above and two feet (0.6 m) in front of the rear axle. This results in approximately 30% of the tractor's weight on the front axle and 70% on the rear axle. For four-wheel-drive and centre-articulated tractors, the CG is located slightly more forward.
The location of the centre of gravity is important as it determines the weight distribution on the wheels. The height of the centre of gravity above the ground is also important, especially when working on slopes or during high-speed turns. A tractor with a lower centre of gravity will generally be more stable. However, a low ground clearance can be problematic when the tractor needs to move over standing crops.
The centre of gravity of a tractor can be determined by suspending the tractor from a point on the front axle using a crane hoist, ensuring that the front and rear axles are horizontal. The centre of gravity will then be on the vertical plane passing through the point of suspension. This process can be repeated using another point of suspension to derive another vertical plane. The intersection of these two planes is the centre of gravity of the tractor.
The centre of gravity of a tractor can also be affected by the addition of weights or equipment. For example, mounting equipment such as a front-end loader or a round bale lifting fork will shift the CG towards that equipment. As the mounted equipment is raised, the CG is also raised, decreasing the tractor's stability. A higher CG allows a side overturn to occur more quickly. Therefore, it is important to consider the location of the fuel tank in relation to the centre of gravity to ensure the tractor remains stable during operation.
