Power Tillers Vs Two Axle Tractors in Mechanize Agriculture. "Bringing a Knife to a Gun Fight"

A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery used in agriculture or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially (and originally) tillage, but nowadays a great variety of tasks. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanized.

The classic farm tractor is a simple open vehicle, with two very large driving wheels on an axle below and slightly behind a single seat (the seat and steering wheel consequently are in the center), and the engine in front of the driver, with two steerable wheels below the engine compartment. This basic design has remained unchanged for a number of years, but enclosed cabs are fitted on almost all modern models, for reasons of operator safety and comfort.

One example of agricultural machinery for soil cultivation is part of a two-wheeled tractors or hand tractor (power tiller / hand tractor). Two wheel tractors or hand tractor (power tiller / hand tractor) is a farm machinery that can be used to cultivate the land and others work with the soil processing devices coupled to / mounted on the rear of the machine. This machine has high efficiency, due to the reversal of soil and cutting can be done at the same time. Two-wheel tractor engine is versatile as it can also serve as a driving force for tools other tools such as water pumps, processing equipment, trailer (trailer), and others 

Four-wheel drive tractors began to appear in the 1960s. Some four-wheel drive tractors have the standard "two large, two small" configuration typical of smaller tractors, while some have four large, powered wheels. The larger tractors are typically an articulated, center-hinged design steered by hydraulic cylinders that move the forward power unit while the trailing unit is not steered separately.

In the early 21st century, articulated or non-articulated, steerable multi-track tractors have largely supplanted the Caterpillar type for farm use. Larger types of modern farm tractors include articulated four-wheel or eight-wheel drive units with one or two power units which are hinged in the middle and steered by hydraulic clutches or pumps. A relatively recent development is the replacement of wheels or steel crawler-type tracks with flexible, steel-reinforced rubber tracks, usually powered by hydrostatic or completely hydraulic driving mechanisms. The configuration of these tractors bears little resemblance to the classic farm tractor design.

Power Tiller

Power tiller is walking tractor mostly used for rotary cultivation in puddle soil and can be replace the animal power more effectively and help in increasing demand for human labour. The small and marginal farmers form major user for custom hiring of power tiller. Power tiller is preferred in small land holding farmer for all farm operations like puddling and preparatory tillage. The machine provides opportunities for self employment in rural areas.

Power Tiller Attachments

Power tiller having all attachments likewise a tractor for all farm operation. Power tiller operated attachments are 1.5 ton trolley, five tynes cultivator, reversible mould board plough, spraying, shorter rotary 340 mm, power tiller reaper, power tiller operated generator.

Features:

    Field coverage/day - 1 to 1.25 acres

• Depth of cut - 20.32 to 25.4cm
• Width of cut - 15.24 to 22.86cm
• Depends on soil condition & usages

Tractor (Two Axle)
The most common use of the term "tractor" is for the vehicles used on farms. The farm tractor is used for pulling or pushing agricultural machinery or trailers, for plowing, tilling, disking, harrowing, planting, and similar tasks. A variety of specialty farm tractors have been developed for particular uses.

Features:

    Field coverage/day - 10 to 20 acres

• Depth of cut - 15 to 30cm
• Width of cut - 18 to 25cm Per Disc (X3)
• Depends on soil condition & usages

NOTE: This literally means that One Two Axle Tractor (One Operator) is Equivalent to 15 to 20 Power Tillers (15 to 20 Operators).

Taraba State is One of the Largest producers of Farm Produce in the Country, hence the need to mechanize Agriculture in the State with the Use of Modern Agricultural Machines while Power Tillers should be acquired to take care of Small scale Farmers in the Rural Areas.
