Disc Plough Overview

Each disc revolves on a stub axle in a thrust bearing, carried at the lower end of a strong stand which is bolted to the ________ beam.

The disc cuts the soil, breaks it and pushes it ________.

In mounted disc plough, the side thrust is taken by the ________ of the tractor.

Disc is made of heat treated steel of 5 mm to 10 mm ________.

Disc angle is the angle at which the plane of the cutting edge of the disc is inclined to the ________ of travel.

Concavity is the depth measured at the centre of the disc by placing its concave side on a ________ surface.

Vertical Disc Plough combines the principle of regular disc plough and disc ______ and is used for shallow working in the soil.

The disc plough is lighter in draft than the mouldboard plough, turning the same volume of soil in similar conditions. In very hard soil, some extra weight is added to the wheel which increases the ______.

The rotary cultivator is widely considered to be the most important tool as it provides a fine degree of pulverization enabling the necessary rapid and intimate mixing of soil besides reduction in traction demanded by the tractor driving wheels due to the ability of the soil working blades to provide some forward thrust to the cultivating outfit. Rotary tiller is directly mounted to the tractor with the help of three-point ______.

A disc plough can be forced to penetrate into the soil which is too hard and dry for working with a ______ plough.

It works well in sticky soil in which a ______ plough does not scour.

The power is transmitted from the tractor PTO (Power Take Off) shaft to a bevel gear box mounted on the top of the unit, through telescopic shaft and universal ______.

Disc plough is much heavier than ______ plough for equal capacities.

From the bevel gear box, the drive is further transmitted to a power shaft, chain, and sprocket AGRI 141 Basic Farm Machineries and Mechanization 28 | P a g e transmission system to the ______.

A levelling board is attached to the rear side of the unit for leveling the tilled ______.

There is one significant difference between mouldboard plough and disc plough i.e. mouldboard plough is forced into the ground by the suction of the plough, while the disc plough is forced into the ground by its own ______.

Disc ploughs are of two types (i) Standard disc plough and (ii) Vertical disc plough. (i) Standard disc plough consists of steel disc of 60 to 90 cm diameter, set at a certain angle to the direction of ______.

A disc plough works well even after a considerable part of the disc is worn off in ______ soil.
