- 1050J
Productivity --> John Deere Dozers Model -> 1050J
Turbocharged/inter-cooled in-line 6-cylinder 12.0 L wet-sleeve Tier-3-certified diesel provides exceptional reliability, power, torque, and fuel efficiency.
* Full-featured hydrostatic drive train delivers power turns, counter rotation, infinite speed range, infinitely variable track speeds, and automatic load sensing.
* Total Machine Control lets you precisely match machine response and operating characteristics to operator preferences for increased flexibility and productivity.
* Power management takes the guesswork out of efficient operation, automatically maintaining peak engine rpm and power efficiency without stalling or shifting.
Comfort --> John Deere Dozers Model -> 1050J
* Wide expanse of glass provides unsurpassed forward visibility; seat is angled 15-degrees for enhanced rear visibility.
* Deluxe seat adjusts seven ways for all-day comfort. Adjustable armrests and foot pedals are standard.
* Ergonomically correct joystick gives intuitive, low-effort control of steering, forward/reverse travel, and ground speed.
* Pilot control and load-sensing hydraulics deliver fatigue-beating low-effort blade operation and predictable response, regardless of the load. Exclusive TMC lets you customize decelerator mode and response, forward/reverse ground speed ranges, FNR shift rate, and forward/reverse speed ratios.
Uptime/Service --> John Deere Dozers Model -> 1050J
* Wide-open service access, same-side daily servicing, and 500-hour engine and 2,000-hour transmission and hydraulic oil and filter service intervals increase uptime.
* Remote drive system test ports, and onboard diagnostic messaging allow quick troubleshooting.
* Hydraulic-driven fans automatically speed up or slow down, operating as needed to keep things cool. Helps conserve power and fuel, while reducing noise and radiator core wear.
* Unique final-drive double seal serves as an early warning that helps avert major final-drive failure and expense.
* Operator station tilts in only minutes for wide-open access to internal components.
