What indicates that the hydraulic system may be malfunctioning?

Fluid leakage and slow operation of attachments are clear indicators of a potential malfunction in the hydraulic system of a crawler tractor. Hydraulic systems rely on fluid to transmit power and facilitate the smooth and effective operation of various attachments, such as blades or rippers. When there is fluid leakage, it suggests that the system may not have sufficient fluid pressure, leading to decreased performance. This can result in attachments operating slower than normal, or perhaps not at all, as they rely on fluid pressure to function properly.

In contrast, the other indicators listed do not specifically point to issues with the hydraulic system. A lack of noise from the engine when started may relate to the engine or electrical issues rather than hydraulics. Inconsistent tire pressure is more relevant to the tractor's mobility and tire integrity rather than the hydraulic operation. Excessive dirt build-up on the chassis, while potentially problematic, generally concerns maintenance and cleanliness rather than direct hydraulic function.
