Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.
The size of a mouldboard plough is expressed as
A. width of cut of each bottom and the number of bottoms
A plough is specified by the width of cut per bottom and number of bottoms, which fix total width. Depth is a setting and power depends on soil.
Which disc harrow has one front gang and one rear gang placed to one side of the tractor centre line?
B. Offset disc harrow
The offset harrow's two gangs work in opposite directions and are offset laterally, letting it work under tree branches. Single-action has two gangs end to end; tandem has four gangs.
Most mechanical rice transplanters require seedlings raised as
B. a mat nursery
The picking fork cuts blocks from a mat, so seedlings must be grown densely on a thin soil layer forming a mat. The roots interlock so the mat holds together when the fork cuts it.
A spinning-disc fertiliser broadcaster distributes granules by
B. throwing them with vanes on a rotating disc
Centrifugal broadcasters throw granules from vaned discs. Drop spreaders use openings along the hopper and pneumatic spreaders use a boom.
Field efficiency is defined as
A. effective field capacity divided by theoretical field capacity
FE = EFC/TFC, always at most 100 %. Power ratios describe tractive or transmission efficiency, not field efficiency.
On a mounted plough, the fore-and-aft level (so front and rear bottoms cut the same depth) is set with the
B. top link
Lengthening or shortening the top link pitches the plough; the lift rod levels it sideways; check chains control sway.
