Which of the following is NOT considered a safety system on a TLB?

The correct answer highlights that hydraulic hoses are not categorized as a safety system on a Tractor Loader Backhoe (TLB). Safety systems are typically designed to protect the operator and bystanders by preventing accidents or ensuring safe operation under various conditions.

Hand holds and steps enable operators to safely enter and exit the machine, which is essential for preventing falls. The loader arm service lock provides a safety mechanism that secures the loader arm in place when maintenance or servicing is being performed, reducing the risk of accidental movement. Reverse warning alarms alert personnel around the machine when it is backing up, enhancing awareness and preventing collisions.

Hydraulic hoses, while crucial for the operation of the TLB, are primarily considered components that facilitate the machine's functionality rather than safety features. They are essential for delivering hydraulic fluid to operate various systems within the backhoe but do not inherently provide protection or safety measures.
