1. A system for providing a dynamic tachometer, the system comprising:
at least one processor;
a memory storage device including instructions that, when executed by the at least one processor, cause the system to:
display, via a digital tachometer, an indication of a current engine speed of a vehicle in relation to a range of normal operating mode engine rotation speeds; and
in response to receiving an indication of actuation of a power takeoff (PTO), the instructions further cause the system to:
update the digital tachometer to:
replace the range of normal operating mode engine rotation speeds with a range of engine rotation speeds associated with PTO operation; and
include a visual indication of upper and lower PTO operation engine speed limit values.
