John Deere 850J - Manual (Page 7)

Four forward and three rear high-intensity halogen work lights are
positioned high for superior illumination.
Lift-cylinder guards keep hydraulic hoses and cylinders out of danger. Blade
hoses are steel-cable supported and Cordura covered for extra protection.
Semi-U blade hoses are routed internally for extra protection and to
prevent snagging.
Air-conditioning condenser is mounted up and away behind the cab for
extra protection and dust reduction.
Cantilevered carrier rollers, recessed segmented sprockets, and trape-
zoidal openings in extreme-duty track shoes help prevent refuse packing.
Uni-body track frames ensure durability. Smooth idler-to-sprocket covers
shed material build-up for easier clean-out.
Sealed electrical center protects fuses, relays, and connections from dirt,
debris, and moisture, ensuring maximum reliability and uptime.
Optional full-width trash rack reduces front-end damage and increases
blade capacity for extra production.
Cab-mounted strobe light is activated whenever the electrical system is
switched on.
The curved shape of the final drive housings resists wrapping and sawing
action of debris.
1. Heavy-duty tank guards help protect the hydraulic, hydrostatic, and
fuel reservoirs. Optional front and rear striker bars help shed material
from the tracks.
2. Unitized mainframe with flush-fit bottom guards forms a smooth
underbelly that doesn’t accumulate or drag trash.

Final Drive Protection:
A) Final drive seal guard
B) Final drive seal guard
C) Stepped labyrinth protection
D) Protected final drive seals
Bolt-on seal guards and
stepped labyrinth housings
make the final drives virtually
impenetrable. They help mini-
mize downtime and expense
by keeping wire, strapping
tape, metal springs, and other
intrusive contaminants away
from final drive seals.
