Here's why:
* Engines don't directly control gear extension. Gear extension is usually controlled by a hydraulic system or a mechanical linkage.
* Engines provide power. The engine's power output (RPM) does affect how quickly and easily the gear can extend, but it doesn't directly cause the extension.
* Gear extension can happen at various engine speeds. You can extend gear at idle, at low RPM, or at high RPM. The engine speed will affect how quickly and powerfully the gear extends.
So, to be more precise:
* Gear extension doesn't cause the engine to spool up.
* Engine speed can influence gear extension speed and power.
Think of it like this:
* Engine: Like a car's engine - it provides the power.
* Gear: Like a car's transmission - it changes the power to different speeds and torque.
The engine provides the power, and the gear system (and hydraulics) use that power to extend or retract.
