wheel tractor-scrapers—the 621K, 623K
and 627K—offer features such as highpressure steering, engine overspeed protection, tire spin reduction, differential lock

Advanced Cushion Hitch uses new software
to dampen end-of-stroke movement of the
load cylinder for a smoother ride; hydraulicsystem refinement simplifies the bowl
quick-drop function; draft arm overflow
guards divert material away from bowl
sides; Auto-Stall assists in quickly bringing
the transmission to operating temperature
for faster transitions from torque-convertor
drive; cab interiors feature a redesigned
dash as well as visibility and operator comfort enhancements; maintenance improvements include an easier-to-service filter
bank; and the Fuel Economy Mode for the
627K adjusts shift points and power distribution for optimum fuel economy.
