Question

In which cultivator, the spacing of the tines are changed by slackening and sliding of bolts?

(a) Cultivator with rigid tines

(b) Cultivator with spring loaded tines

(c) Duck foot cultivator

(d) Mounted cultivator

The question was posed to me in a job interview.

My enquiry is from Cultivators in division Harrows, Cultivators and Intercultural Implements of Farm Machinery

Answer 1

Correct option is (a) Cultivator with rigid tines

To elaborate: Generally, rigid tines do not deflect during the working in the field. These tines are bolted between angle braces and tried to the main bars by use of good quality clamps and bolts. So, we can change the spacing simply by loosening of the bolts, adjusting the braces and then tightening the bolts.
