Which tractor-derived pressure is used to operate attachments and additional equipment?
- Engine oil pressure.
- Condensed air pressure.
- Correct answer: Hydraulic oil pressure.
- Steam water pressure.
Why this is the answer
The correct answer in the official bank: Hydraulic oil pressure.
In a tractor, a pump driven by the engine pushes hydraulic oil under pressure. This pressure operates the lifting device, loaders and other attached equipment. Engine oil is for lubricating and cooling the engine itself, not for operating equipment. So the pressure that operates the additional equipment is hydraulic oil pressure.
