This set of Farm Machinery Multiple Choice Questions & Answers (MCQs) focuses on “Tillage System”.
1. Which classification of tillage involves initial major soil working operation?
a) Secondary tillage
b) Primary tillage
c) Tertiary tillage
d) Primary & Secondary tillage
View Answer
Explanation: Primary tillage is normally designed to reduce soil strength, cover plant materials, and rearrange aggregates. The operations performed to open up any cultivable land with a view to prepare a seed bed for growing crops is known as Primary tillage.
2. Which primary tillage operation is performed to cut, break and invert the soil partially or completely?
a) Ploughing
b) Winnowing
c) Threshing
d) Harrowing
View Answer
Explanation: The main implement for primary tillage is plough used for ploughing operations. Ploughing is the primary tillage operation, which is performed to cut, brake and invert the soil partially or completely. Ploughing essentially means operating the upper crust of the soil, breaking the clos and making the soil suitable for sowing seeds.
3. What type of mouldboard is short but broader with a relatively abrupt curvature?
a) Sod or breaker
b) Slat
c) Stubble
d) General purpose
View Answer
Explanation: Stubble type’s relatively abrupt curvature lifts, breaks and turns the furrow slice. Its curvature is not gradual but it is abrupt along the top edge. This causes the furrow slice to be thrown off quickly, pulverising it much better than the other types of mouldboard.
4. A flat plate which bears against and transmits lateral thrust of the plough bottom to the furrow wall is known as __________
a) Landside
b) Tail piece
c) Jointer
d) Coulter
View Answer
Explanation: Landside helps to resist the side pressure exerted by the furrow slice on the mouldboard. It also helps in stabilizing the plough while it is in operation. Landside is fastened to the frog with the help of plough bolts. The rear bottom end of the landside is known as heel which rubs against the furrow sole.
5. Which plough accessory is used to turn over a small ribbon like furrow slice directly in front of the main plough bottom?
a) Coulter
b) Gauge wheel
c) Jointer
d) Land wheel
View Answer
Explanation: Jointer is a small irregular piece of metal having of a shape similar to an ordinary plough bottom. It looks like a miniature plough. The small furrow slice that is cut from left and upper side of the main furrow slice and is inverted so that all trashes on the top of the soil are completely turned down and buried under the right-hand corner of the furrow.
6. Reversible ploughs which have single bottom with such an arrangement that the plough bottom is changed from right hand to left hand by rotating it approximately 180°?
a) Turn Wrest plough
b) Disc plough
c) Chisel plough
d) Rotavator
View Answer
Explanation: Turn Wrest plough, while moving in one direction the plough throws the soil in one direction and at the return trip the direction of the plough is changed, thus the plough starts throwing the soil in the same direction as before.
7. What is the disc angle of a good plough?
a) 35°-39°
b) 42°-45°
c) 23°-27°
d) 59°-63°
View Answer
Explanation: Disc angle is the angle at which the plane of the cutting edge of the disc is inclined to the direction of travel. Usually, the disc angle of good plough varies between 42° to 45°.
8. Which plough is the combination of principles of the regular disc plough and the disc harrow and is used for shallow working in the soil?
a) Vertical disc plough
b) Chisel plough
c) Subsoiler
d) Standard disc plough
View Answer
Explanation: Vertical disc plough is also known as Harrow plough or One-way disc plough. Its action is intermediate between regular disc plough and disc harrow. It has a frame, wheel arrangement, depth adjusting devices.
9. Which plough is used to cut and pulverise soil by impact forces by means of a number of rotary tynes or knives?
a) Rotating auger plough
b) Rotavator
c) Chisel plough
d) Rotary plough
View Answer
Explanation: Rotary plough is also called rotary tiller. It is suitable for shallow cultivation and weed control. The rotary tiller consists of a power-driven shaft on which knives or tynes are mounted to cut the soil and the trash.
10. A strip of land left unploughed at each end of the field for the tractor to turn is known as _______
a) Head land
b) Dead furrow
c) Back furrow
d) Crown
View Answer
Explanation: A strip of land left unploughed at each end of the field for the tractor to turn is known as head land. The head land is about 6 metres wide for tractor plough.
