Many accidents with agricultural tractors happen due to lack of maintenance or incorrect services in the brake and steering systems. Therefore, it is important to understand how it works and take care of the maintenance of these mechanical assemblies. According to the text, which of the following statements is true?
The brake system uses a friction mechanism to stop the rotation of the axle that drives the wheels.
The steering system is a hydraulic system that starts working after the engine is turned on.
The brake system of agricultural tractors allows independent braking for each axle end.
The steering system is a mechanical system that does not require any hydraulic components.
a) Only I and II are true.
b) Only II and IV are true.
c) Only III and IV are true.
d) Only I and III are true.
e) Only II and III are true.

De acordo com o texto, a alternativa correta é a letra D) Apenas I e III são verdadeiras. O sistema de freio dos tratores agrícolas permite a frenagem independente para cada extremidade do eixo, e o sistema de direção é um sistema mecânico que não requer componentes hidráulicos.
