6 L SERIES CRAWLER DOZERS 750L I 850L Climb in and feel the power. For site prep or fi nish grading, road-and-bridge, residential or commercial work, Case 750L and 850L crawler dozers have the power to get the job done. Whether you need stability to work on steep slopes or extra power to carry your load through a turn, Case dozers deliver. And they do it with exceptional control and maneuverability. Like all Case equipment, these dozers are industry leaders when it comes to serviceability. They re also top of the line in terms of operator comfort. What that means for your business is more time productive time running the machine and less time maintaining it. And that delivers more money to the bottom line. More power Tier 3-certifi ed engines on the 750L and 850L produce 84 and 96 net horsepower, respectively. That s enough muscle to move any material around the job site. The Case PowerStat hydrostatic drivetrain delivers greater drawbar pull at all travel speeds for more push power and productivity. The combination of 10 speed settings with infi nitely variable steering provides maximum maneuverability with counter rotation. A variable-displacement dual-path hydrostatic drive delivers plenty of pulling power. Easy operation Single-lever speed control provides adjustable steering for easy, precise operation. By tilting the control right or left, operators can slow the track on either side to turn the machine. This maintains power to both tracks, letting you push a full load through a turn without braking or raising the blade. Operators can also adjust the sensitivity of the steering and the forward/reverse modulation to suit personal preference or conditions. These easy-to-operate controls boost productivity in any application, making the 750L and 850L ideal for residential, commercial or road-and-bridge work. 750L LT 750L WT 750L LGP

8 L SERIES CRAWLER DOZERS 750L I 850L Tier 3-certified engine The Case 750L and 850L crawler dozers are powered by turbocharged Tier 3-certifi ed, fueleffi cient Case Family IV engines. The 4.5-liter and 6.7-liter engines deliver 84 and 96 net horsepower respectively and provide cleanburning power and plenty of torque to move more material per hour. Adjustable blade pitch The built-in pitch-adjustment tool makes it easy to set the blade pitch to match soil conditions, with a range from 52 degrees forward to 60 degrees rearward. Exclusive hydrostatic drive Operation is easy with single-lever control of speed and direction. Combine that with the Caseexclusive PowerStat hydrostatic drive, and you have the power and control you need to push the fullest blades of material, even through curves and turns. Undercarriage durability Based on the conditions you re most likely to encounter, you can choose from Case Lubricated Track (CLT) or Case Extended Life Track (CELT) for optimum undercarriage performance. Regardless of which you select, you ll fi nd that the triplereduction, high-capacity fi nal drive with helical-cut gears makes the 750L and 850L among the quietest dozers in their size class. Track options The 750L and 850L are available in long track (LT), wide track (WT) and low ground pressure (LGP) versions to match operating conditions. The 850L also comes in extra long track (XLT). Both dozers feature a 49-degree sloping track frame cover and ample space between track and machine to keep the undercarriage free of dirt and debris. 4

9 Quieter, comfortable cab Case dozers feature one of the quietest cabs in the industry. Conveniently placed, easy-tooperate controls and an optional air-ride seat help keep the operator comfortable throughout the day. Heat and air conditioning are standard cab features. Low operating height The height of the ROPS is only 109 inches on both the 750L and 850L, making these machines ideal for residential construction projects. The low overall operating height also makes them easier to transport More uptime Easy maintenance keeps your machine in top shape. Quickaccess diagnostic test ports are standard on these crawler dozers. Swing-out service panels and spin-on fi lters reduce maintenance time, too. Easy-access tilt cab The hydraulic, easy-tilt operator platform gives you access to the drivetrain in less than 10 minutes. Attachment options Several attachment options are available, including specialty blades, rippers, drawbars, winches and more. 5

10 L SERIES CRAWLER DOZERS 750L I 850L Wide-open visibility and unbeatable comfort The fi rst thing you ll notice on the Case 750L and 850L is how easy it is to get into the cab with the wide doors. Once you re sitting in the optional air suspension seat, you can adjust the seat and controls to your liking. Your visibility is clear to the blade and the entire job site. The high-capacity heater and air-conditioning will handle the toughest temperatures. This environment helps operators be more productive. Easy maintenance means more uptime Case designed these crawler dozers, like all Case machines, to be easy to maintain. We know that the easier it is to service and maintain equipment, the more likely it gets done. And that translates into uptime. Ease of maintenance starts with eye-level fl uid sight gauges and ground-line access to key service checkpoints. These include coolant and hydraulic system gauges and quick-access diagnostic ports. An auto belt tensioner, swing-out service panels and spin-on fi lters also speed up routine maintenance. Service access on Case dozers is second to none. With the hydraulic, easy-tilt operator platform, access to the drivetrain takes less than 10 minutes. The bottom line is that these machines are engineered for easy daily maintenance and routine service. That increases uptime and lowers ownership costs.
