P AGES 2–3 Built with the same kind of forward thinking as our first hydrostatic dozer more than 30 years ago, 750J and 850J Dozers continue to define the way earthwork gets done. Their unique state- of-the-art T otal Machine Control (TMC) enables an operator to customize machine operation and response to personal preferences.
Tier 3-certifi ed John Deere diesels deliver power without compromise in all conditions. Deere’ s unique T otal Machine Control lets an operator customize the crawler’ s operational characteristics and response, and even records machine usage.
P AGES 4–5 All dozers move the earth. But if you want one that does more with a lot less effort, you’ll choose a John Deere J-Series. State-of-the-art electronic controls put you in complete command of a whole arsenal of hydrost at ic advantages, including power turns, counterrotation, a n d infi nitely variable travel speeds.
Low-effort controls command the blade and a full-featured hydrostatic drivetrain, ensuring predictable response at all times in all conditions. Simply set the maximum desired ground speed and the power - management system automati- c ally maintains peak engine rpm and power effi ciency without stalling or shifting.

Cab view Mo Generous hydraulic fl ow and precise metering ensure powerful and quick blade response, while providing a natural “feel” that will enhance any operator’ s grading skills.
Choose the decelerator function that’ s right for the job. Slow both ground speed and engine rpm, or ground speed only to help maintain traction without affecting engine power and hydraulic response.

P AGES 8–9 Designed and built with state-of-the-art tools and techniques by a quality-conscious workforce at our world-class facility in Dubuque, Iowa, the J-Series are loaded with uptime-boosting features.
Bypass start protection, automatic park brake, convenient handholds, and slip- resistant steps help keep the operator out of harm’ s way. Bolt-on wear parts for the chain guides and push-beam mounts virtually eliminate diffi cult and time-consuming cut-and-weld repairs.
Keep y our cool and b u rn l e s s fu e l . K e e p y o u r c o o l a n d b u rn l e s s fu e l . J-Series Dozers are designed to run cool regardless of what’ s in the air or underfoot. Their highly effective cooling system employs a hydraulic- driven variable-speed suction fan that operates only as needed for maximum power and efficiency .
Variable-speed fan automati- cally speeds up or slows down, operating only as needed to keep things cool. Helps conserve power and fuel, while reducing noise. Air isn’t blown into the coolers, so engine and transmission reach operating temperatures more quickly in cold weather .
P AGES 12–13 Y ours isn’t just any business. Why settle for just any crawler? Choose a J-Series Dozer in standard, long- track, wide-track, wide-long track, and low ground- pressure confi gurations with inside-mounted P A T or outside-mounted straight or semi-U blades.

Swing open their hinged doors and you’ll uncover lots of the ways these crawlers help keep maintenance to a minimum. Same-side daily ser vice points make quick work of the daily routine, and extended engine oil and drivetrain service inter vals let you work longer between changes.
Hinged side shields open wide for ground-level access to dipsticks, fi ll tubes, batteries, master electrical shutoff, and engine, transmission, and hydraulic fi lters. Separate hydraulic and hydrostatic reservoirs eliminate any possibility of cross-contamination.
