John Deere 450D LC - Manual (Page 8)

Three welded bulkheads in the heavy-duty boom
resist torsional stress. Rigid, reinforced D-channel
side frames resist impacts, providing maximum
cab and component protection.
Highly effi cient, heavy-duty cooling system keeps
things cool. Reversing fan back-blows cooler cores
to reduce debris buildup. It’s a welcome addition
that will increase uptime.
Perforated screens behind the side shields
serve as a “fi rst fi lter,” helping prevent trash
entry. Anything that passes through will also
clear the cooler cores.
Large box-section track frames, thick-plate
single-sheet mainframe, and massive swing
bearing deliver rock-solid durability.
Boom, arm, and mainframe are so tough, they’re
warranted for three years or 10,000 hours.
1. Heavy-duty, slow-running sleeved diesel
delivers long-term engine durability.
2. Compare the size of the 450D LC’s carrier
and bottom rollers, idlers, and sealed and
lubricated chain. This is one heavy-duty
undercarriage.
3. Hydraulically driven fan runs only as
needed, reducing fuel consumption and
debris fl ow through the coolers.
4. State-of-the-art multifunction diagnostic
monitor helps troubleshoot problems and
defeat downtime.
