Large capacity fuel tanks let you run longer between fill-ups.
Four steel plates support the far end of the boom pivot,
extending the life of the pins and protecting the boom
cylinder hoses.
Service intervals for engine oil, transmission filter, and hydraulic
oil have been extended to 500, 1,000, and 4,000 hours.
Wet-sleeves provide uniform engine cooling and longer
durability than cast-in-block designs.
Standard features such as bypass-start protection, automatic
park brake, convenient handholds, and slip-resistant steps help
keep the operator out of harm’s way.
1. Electrical distribution center employs
highly reliable circuit-board technology
and solid-state switches, eliminating
numerous wiring harnesses, fuses,
relays, and connectors.
2. Optional reversible fan automatically
reverses every 30 minutes, ejecting
debris from the radiator and coolers
for more uptime and productivity. Or
just hit a button to choose your own
cleaning cycles.
3. Planetary final drives are mounted
inboard. Since gear size isn’t limited
by wheel hub diameter, larger, more
durable components are used. Hydraulic
wet-disk brakes self-adjust for wear.
4. The coupler’s single floating cylinder is
well protected, yet accessible. Integrated
coupler plumbing, flat-face O-ring seal
couplers, and cable-reinforced hoses
further enhance durability.
5. Sealed, gold-pin electrical connectors
resist corrosion for superior long-
term integrity.
