5.1 Die aankoop van ‘n trekker is ‘n reuse finansiële uitgawe vir ‘n boer - NSC Agricultural Technology - Question 5 - 2016 - Paper 1

The implement in Column A is ideal for lighter tasks and offers efficiency for smaller operations.

The implement in Column B is suitable for heavier tasks, providing better stability and performance.

The tractor (c) will be a better choice because it has a smaller financial outlay, is cost-effective, reduces diesel usage, is easier to maintain, and allows for better access to areas with minimal ground disturbance.

The four advanced technologies that should be equipped on tractor (a) include Variable Rate Technology (VRT), GPS for precision farming, Yield Monitoring Systems, and Autosteer Systems.

A: Clutch, B: Gearbox, C: Drive shaft.

A: Round bale machine/Roller type, B: Square bale machine/Stacker or elevator type.

The density can be changed by adjusting the speed of the movement of the bale in the baler while managing the resistance on the material.

A farmer might prefer bale machines A for optimal storage, easier handling, and better utilization of space.

To harvest maize with a combine harvester, the process involves correctly setting the machine, adjusting the knife height, and ensuring the combine collects and processes the maize effectively while minimizing losses.

Three safety measures when operating the hammer mill include wearing eye protection, ensuring the machine is grounded to prevent electric shock, and avoiding loose clothing that can get caught in the machinery.

A: Single-acting cylinder, B: Double-acting cylinder.

The distance between the tractor and implement must be adjusted to avoid excessive wear and ensure effective power transfer.

Two ongoing expenses a farmer must consider include maintenance costs and fuel expenses for the tractor.

The gear ratio calculation is given by the formula: Gear Ratio = Toothed Ratio = 44 / 22 = 2:1.

The final drive increases torque due to the gear ratio which multiplies the input force applied from the tractor.

To calculate the speed of the driven gear, using the relationship: Speed of Driven = Speed of Driver * (Teeth Driver / Teeth Driven).

Thus, the speed of the driven gear is: ext{Speed}_{ ext{driven}} = 200 imes rac{22}{44} = 100 ext{ r/min}
