Subtopic: Rasp bar, spike tooth and axial flow cylinders

Question Statement:

A tractor implement has a working width of $4.0\text{ m}$ and operates at a forward speed of $4.0\text{ km/h}$. The theoretical field capacity (TFC) of the machine is:

Options:

  • (A) $1.60\text{ ha/h}$
  • (B) $1.92\text{ ha/h}$
  • (C) $1.28\text{ ha/h}$
  • (D) $2.40\text{ ha/h}$

Answer Key:

A

Step-by-Step Solution & Explanation

Theoretical field capacity (TFC) in ha/h is given by: $\text{TFC} = \frac{W \times S}{10}$ Where $W = 4.0\text{ m}$ and $S = 4.0\text{ km/h}$: $\text{TFC} = \frac{4.0 \times 4.0}{10} = 1.60\text{ ha/h}$
