Introduction
CBT 8240 Agricultural Tractor
The CBT 8240 is a two-wheel drive agricultural tractor manufactured in Brazil between 1984 and 1988. Designed for general field operations, it features a robust construction and mechanical systems aimed at reliability and ease of maintenance.
Engine and Performance
The tractor is powered by a Perkins E-4.236 liquid-cooled, four-cylinder engine with a displacement of 3.8 liters. It produces 80 horsepower (59.7 kW) at a rated speed of 2200 RPM and provides 211.2 lb-ft (286.4 Nm) of torque at 1400 RPM. The engine intake system utilizes a dual dry air cleaner to ensure efficient filtration in dusty agricultural environments.
Transmission and Drivetrain
The drivetrain consists of a two-wheel drive configuration paired with a manual transmission. Operators can choose between two primary gear setups: a 6-forward and 2-reverse speed transmission or a 4-forward and 4-reverse speed configuration. Both options utilize a dry disc clutch system and require 40 liters of oil for lubrication.
Hydraulics and PTO
The hydraulic system features a 40.1-liter capacity. The tractor is equipped with a Category II rear hitch, capable of lifting 3,307 lbs (1500 kg) measured at 24 inches (610 mm) behind the lift point. Power take-off (PTO) operations are supported by a standard 540 RPM rear shaft.
Dimensions and Handling
With an operating weight of 8,400 lbs (3810 kg), which can be increased to 10,550 lbs (4785 kg) with ballast, the CBT 8240 offers stability for various tasks. The tractor features hydrostatic power steering and hydraulic disc brakes to facilitate maneuverability. The front tread is adjustable from 141 to 192 cm, while the rear tread ranges from 139 to 210 cm.
Conclusion
The CBT 8240 represents a period of Brazilian agricultural machinery development, offering a straightforward, mechanical platform. Its power-to-weight ratio and simple design make it suitable for a wide range of standard pulling and implement-based farming tasks.
