ENGINES OVERVIEW

The Case 311 tractor features a 2.4L 4-cylinder engine available in both gasoline and LP gas variants, offering flexibility in fuel choice; gasoline provides higher torque for heavy-duty tasks, while LP gas offers cleaner emissions and lower operating costs. However, the smaller engine size may limit power output compared to larger tractors, making it less suitable for extensive agricultural applications. Ideal for small to medium-sized farms, the Case 311 excels in lighter fieldwork and utility tasks.

ENGINE DETAIL 1

The Case 311 tractor features a J.I. Case G148 gasoline engine, which, with a 148 ci (2.4 L) displacement and 7.1:1 compression ratio, is optimized for moderate power output suitable for light to medium-duty agricultural tasks. The engine’s configuration and design, including the oil bath air cleaner, enhance durability and reliability, minimizing maintenance needs. However, its 6-volt starter system may present challenges in cold weather starts compared to modern 12-volt systems, potentially affecting operation in harsher conditions.

ENGINE DETAIL 2

The Case 311 tractor features a 2.4L LP gas 4-cylinder engine with a relatively high torque output, which is advantageous for agricultural tasks requiring sustained power at lower RPMs. Its oil bath air cleaner enhances engine longevity and efficiency by filtering particulates, although it may require more maintenance compared to dry filters. The design, with a 3.375-inch bore and 4.125-inch stroke, promotes good torque characteristics, ideal for tilling or plowing, but could limit the maximum speed due to the conservative rated RPM of 1750.

J.I. CASE 311 ENGINES

The Case 311 tractor is equipped with a 2.4L 4-cylinder engine, available in both gasoline and LP gas variants, offering flexibility in fuel choice. With a 13-gallon (49.2L) fuel tank capacity, it provides reasonable operational endurance for small to medium farming tasks. However, the limited power output may limit its application in heavier agricultural work, thus it's best suited for lighter operations or smaller plots.

TRANSMISSIONS OVERVIEW

The Case 311 tractor's 4-speed sliding gear transmission offers a total of 12 effective speeds, providing versatility for various agricultural tasks. A key advantage is the ability to efficiently manage power delivery and optimize fuel consumption across different field conditions. However, the potential challenge lies in the mechanical complexity of the sliding gear system, which may require regular maintenance to ensure smooth operation.

TRANSMISSION 1

The Case 311 tractor features a sliding gear transmission with 4 forward and 1 reverse gear, allowing for versatility in various field applications. Its dry disc clutch with a diameter of 234.9mm provides reliable power transfer, though it may require more frequent maintenance compared to wet clutches in terms of wear and tear. Ideal for lighter agricultural tasks or small farm operations, its performance can be challenged under heavier loads or demanding terrains due to the gear configuration.

TRANSMISSION 2

The Case 311 tractor's Tripl-Range transmission enhances versatility by offering 12 forward gears and 3 reverse, allowing for optimal speed and torque management across various tasks. The combination of a 234.9mm dry disc master foot clutch and wet disc traction hand clutch promotes seamless transitions and better traction control under heavy loads. This configuration is advantageous for operations requiring frequent gear shifts, such as plowing or hauling, but may present challenges in complex terrain where precise speed control is essential.

MECHANICAL

The Case 311 tractor features a two-wheel drive system, which enhances fuel efficiency on flat surfaces but may limit traction in challenging terrains. The 6-inch disc brakes provide reliable stopping power, yet may require more frequent maintenance compared to larger brake systems. The open operator station allows for better visibility and airflow, but operators may face exposure to the elements during operation.

J.I. CASE 311 TIRES

The Case 311 tractor features a front tire size of 5.50x16 and rear tires at 11x28, which provide a balanced weight distribution ideal for agricultural tasks. The larger rear tires enhance traction and stability, particularly in plowing and tilling scenarios, but may limit maneuverability in tight spaces. Ensure proper tire pressure and maintenance for optimal performance and longevity when operating in various soil conditions.
