NOTE: It is okay to change travel speed while traveling:
The travel motors will shift immediately from high to
low when low speed is selected.
The travel motors will not shift from low to high
when high speed is selected until:
• Engine speed is at high idle
• Hydraulic pressure is low enough to allow the
motors to shift from low to high speed
