Power Train
Designed for power, durability and performance.
Engine
The MHI S4Q2 Turbo engine meets EPA Interim Tier 4 emissions requirements 
and delivers superior power to help you get more done.
Chassis
Rear axle oscillation helps assure four wheel ground contact for optimum traction 
and stability. Heavy duty axles with outboard planetary reduction gears are built 
for durable performance. Optional differential lock is available in the front axle 
only or both axles and can be easily engaged by a foot switch to the left of the 
steering column to increase tractive effort in poor underfoot conditions.
Power Train
Two-speed closed loop hydrostatic transmission delivers smooth transition 
from full rimpull to runout. Precise inching control and smooth acceleration 
and deceleration minimize operator fatigue. Optional speed (creeper) control 
and hand throttle are also offered.
Ride Control
The optional Ride Control System further enhances the already smooth road 
handling of the machine, resulting in increased operator comfort and higher 
productivity. It is suited for extreme applications where operators need to maintain 
bucket material load or carry a heavy work tool and have a smooth ride.
Linkage
Built for strength.
Z-Bar Design
The high performance Z-bar 
loader design is built for strength, 
visibility and versatile attachment 
usage. The Z-bar linkage gives the 
operator a clear view to the work 
tool and excellent dump clearance 
while maintaining good cycle times.
