Tractors in Ghana

Classification and types of tractors Scientific and technological progress consistently covers new areas - both the automotive industry and the tractor industry are being improved. Agriculture is moving from the stage of semi-automated work, when a person drives a tractor, to fully automated work, when the unit executes the entire program according to the algorithms and commands that were previously set. But in order to work with equipment, you need to know its design, types and methods of application. Tractors are distinguished by the mover, frame, traction class and purpose. Depending on the type of equipment, it performs various tasks in agricultural, municipal or construction areas. The units are capable of performing most of the tasks that heavy and high-torque machines can only face. The tractor driver is responsible for moving the implement. According to the type of movement, the equipment is classified into wheeled and tracked. For a wheeled unit,   Tractors in Ghana the traction force is created due to the movement of the wheels, and for a tracked unit, due to the tracks. Machines with a caterpillar type of propulsion move better over difficult and difficult terrain than wheeled ones, so they are used in difficult terrain. The traction force of a wheeled tractor is created by the movement of the wheels. Cars are both four-wheeled and three-wheeled. The three-wheel machine is designed for cotton plantings to maintain row spacing. The wheels to which the movement is transmitted from the engine are called driving, and the wheels that guide the equipment are called guides. Wheel formulas are 4x4 (four-wheel drive) and 4x2 (rear-wheel drive). Units in which the movement from the engine is transmitted to four wheels are all-terrain tractors. On a wheeled vehicle, you can move on public roads, unlike vehicles with a caterpillar type of propulsion, but the grip on the ground on a wheeled unit is much lower than on a caterpillar one. On soft and wet ground, the wheels can bog down. All-wheel drive vehicles do not slip on loose ground, but due to their large mass they cause damage to the soil, so heavy tractors are equipped with ultra-wide wheels of two or three pairs on both axles. The advantage of a caterpillar tractor over a wheeled tractor is stable movement on soft, wet ground; caterpillars cannot dig into the ground like wheels. The track rollers move along the track chain, distributing the weight of the machine over the entire surface of the mover, so this technique causes less damage to the soil. The undercarriage of the caterpillar unit consists of a frame, propulsion and suspension. The design of the skeleton can be either frame or semi-frame. For example, the frame of the DT-75MV tractor consists of longitudinal and transverse bars, which are interconnected by rivets. The track rollers are connected to the frame of the equipment by means of a suspension, which transfers the load to them and is responsible for smooth movement over rough terrain. The traction force of a tracked vehicle is greater than that of a wheeled vehicle. The main disadvantage of this unit is that the caterpillar tractor cannot move on public roads, because the caterpillars destroy the asphalt. The skeleton is the main part of the equipment that bears the load. All the main elements of the machine are fixed to the frame. According to the type of skeleton, the units are: The frame consists of longitudinal spars, on which transverse beams are fixed to install the main units of the machine. The mass of frame equipment is greater than semi-frame or frameless, but its advantage is rigidity, strength and easy access to individual mechanisms. If repair is necessary, you can remove a separate part of the mechanism and replace it without disassembling the entire unit. The frame frame is installed on equipment with a caterpillar type of mover. Attachments are fixed with brackets on the frame. The semi-frame frame consists of cast hulls on which the main components of the equipment are attached and several spars for attaching the power unit. The advantage of this type is the availability of maintenance of the main components of the unit, but access to secondary mechanisms is difficult. https://tonaton.com/s_274-tractors
