Compact Excavators Why a compact excavator? Don’t let their small size fool you; compact excavators are powerful digging machines with advanced hydraulic systems that can often outperform larger tractor loader backhoes, which are limited to only 180 degrees of workgroup movement. The house on a Bobcat ® compact excavator can continuously rotate 360 degrees. This allows for enhanced spoil placement, BUrIeD UTILITY BUrIeD UTILITY Independent boom swing provides offset digging capabilities, enabling you to dig square holes, or on each side of a buried utility without repositioning the machine. Try that without repositioning your backhoe! Compact Excavator Tractor Loader Backhoe Operator offset on a compact excavator positions the operator to the side of the boom for an unobstructed view of the attachment. On a tractor loader backhoe, you have to lean around the boom to see the attachment. 2 superior visibility and reduces repositioning for work in tighter spaces. A tracked undercarriage gives you additional benefits like superior flotation compared to a wheeled machine. Also, compact excavators use less fuel and can be hauled with lighter, more fuel-efficient trucks, keeping your hourly costs down. 180o Greater flexibility When working next to objects, an excavator gives you much more flexibility. In this situation, a tractor loader backhoe may be limited to only 45 degrees of workgroup movement. The excavator excels at the same situation by having up to 180 degrees of movement—allowing you to place spoil where you need to, or even load a truck behind the machine. 45o What makes Bobcat excavators the best? n Advanced Hydraulics n More Horsepower n FastTrack Drive System n Panoramic Serviceability n Comfort Cab n Intrack Swing Frame n Attachments Now n Do More Than Dig n More Model Selections n Uptime Protection The Only One! Bobcat is the only company that manufactures compact excavators in the United States. Obviously, this means better dealer support, parts availability and manufacturer’s support as well as overall quality. 3 Advanced The most important way to determine an excavator’s performance is to feel the balance between the hydraulic system and the engine horsepower. It’s the guts that determine the true performance of the machine. Whether it is a closed center valve, MOre POWerFUL High-efficiency, torque-limiting piston pumps help advanced hydraulics deliver more usable power by continuously responding to loads. Matching force to demand, the workgroup maintains brute arm and bucket forces in demanding conditions. More power means more production, and more production means more profi t. Closed center valve Piston pump SMOOTHer Other brands claim they are smooth but are often just slow. Coupled with cushioned cylinders, Bobcat advanced hydraulics feature exclusive control valve systems that deliver consistent oil flow to all functions. This delivers smooth operation without sacrificing cycle times. Bobcat excavators are both smooth and fast, so you can get your work done more quickly. 4 Hydraulics piston pump, load-sensing hydraulics or cushioned cylinders, each Bobcat ® model is engineered with advanced hydraulic components that maximize power, speed, predictability and control. This ensures Bobcat excavators deliver the performance you demand. MORE PREDICTABLE The same Bobcat-exclusive control valves that deliver smooth operation also deliver a predictable workgroup. They provide the level of house, boom, arm and bucket control you expect in the most challenging work environment. It’s the confidence in these precise movements that determines whether you complete the job using your machine, or with two guys and a pair of shovels. faster True cycle times aren’t measured in a dealer parking lot. They’re measured on the job, under load. Matching cylinder size to pump capacities, Bobcat advanced hydraulics deliver industry leading cycle times. Try Bobcat against other brands in real life situations, such as loading trucks, placing boulders or trenching. You’ll get the job done faster with Bobcat excavators. 5 6 More Horsepower t ca s b nd a Bo r B er Oth eNGINe HOrSePOWer We pack in more horsepower than other manufacturers–producing excavators with superior performance under load as well as improved compound use of multiple functions. This loaded performance is easily measured in increased slew torque, faster cycle times and maximum auxiliary hydraulic performance. The end result is more work per hour in the toughest conditions and increased attachment performance. HOrSePOWer TO WeIGHT OPerATING WeIGHT HP to Weight Bobcat® excavators have more engine horsepower than other brands of the same size. HYDrAULIC HOrSePOWer Bo HYDrAULIC FLOW When you purchase your trucks, do you purchase the smallest-horsepower engine available? The same reason you demand more horsepower in your trucks is the same reason you should demand it in your compact excavators; more power means more performance under load. bc BOBCAT at HYDRAULIC HORSEPOWER ADVANTAGE O Br ther an ds HYDrAULIC PreSSUre Hydraulic Horsepower By having more engine horsepower, Bobcat excavators generate more hydraulic horsepower where it counts – under maximum flow and maximum pressure. This allows the excavator to utilize flow at higher pressures, which translates into faster cycle times under load. Simply put, they dig stronger and faster. 7 FastTrack Drive System FastTrack™ drive system, the first and only allhydrostatic drive system in the industry, creates the most productive excavator on the market. Unlike other excavators, FastTrack-equipped machines have separate piston pumps and high-torque drive motors to power the left and right tracks independently from each other, and from the rest of the hydraulic system. 8 A FastTrack excavator’s low speed–the speed in which you backfill, grade and doze– is as fast as other brands’ high speed. This means you can backfill, grade and doze at twice the speed of other excavators. It gives you muscle to push through heavier piles of material and move faster around your jobsites—boosting your productivity. This feature also provides smoother turns under a load and more gradual turns on surfaces like asphalt and concrete. ds ran B r e Oth WORK A FastTrack excavator is nearly twice the speed of other machines. You can move the machine much faster within or between jobsites and work faster. ™ ck ra T t s Fa TIME bobcat Perfect balance of speed, power, and precision for 30% faster backfilling. The FastTrack Drive System provides a smooth backward and forward arc to let you backfill quicker. The hydrostatic drive also allows you to push larger heaps of spoil in one pass. If time is money, then you can’t afford to be without the innovative FastTrack drive system! Other brands FastTrack Drive Provides • Faster backfilling • Faster grading • Smoother turns • Faster and smoother production 9 Panoramic Serviceability Bobcat makes it easy to find and reach your engine checkpoints—so daily maintenance actually gets done every day. Comparing our service access to other excavators is like comparing a 60 in. plasma to a 15 in. blackand-white T V. The swing-open tailgate and side access hood provide excellent access to the engine and pump package, valve bank, cooling system and associated plumbing. A centralized grease bank makes easy work of lubricating the slew bearing, slew pinion and swing cylinder. Track tensioning is performed via an easy-to-reach, wellprotected grease cylinder fitting. What does panoramic serviceability mean? Preventative maintenance gets completed, reducing operating costs and improving your bottom line.

How does Bobcat provide superior comfort levels to other machines? We start by giving you the most cab space in the industry. In general, we provide 20% more interior cab volume than other brands. Whether you have size 13 or size 8 boots you’ll notice considerably more room at your feet, legs and knees, and more room for your arms and upper body. Bobcat has the largest cab entry/exit room in the market. We also provide a kingsized adjustable suspension seat for ultimate comfort during long hours of operation. An in-cab pattern selector allows you to change from an “excavator” to a “backhoe” control pattern from the seat of the cab—no keys, special tools or panel removal is required. We didn’t forget the other cab details either. Features such as strategically positioned heat and air-conditioning vents direct air flow where you need it most. Other elements such as radio-ready cabs and fingertip-controlled auxiliary hydraulics all add up to increased operator comfort. Bobcat believes that there is a direct relationship between operator comfort and productivity. If you can comfortably stay in the seat longer, you will be able to get more work done.

Our swing castings and cylinders stay within the tracks when offset digging – giving you the ability to truly dig flush up against an obstacle and increasing your ability to work in tight areas when in an offset dig position. Bobcat ® excavators are engineered to operate in the smallest of workspaces. Bobcat’s exclusive In-Track Swing Frame keeps the swing casting within the tracks when in an offset digging position. This picture depicts the “unicorn effect” found on other brands. The protruding cast and cylinders limit access to tight areas and areas around obstacles. 14 Attachments Now Most manufacturers claim that their excavators are attachment-ready. However, the exchange system, hoses and couplers, controls and clamp mounts may actually be pricey add-ons. Bobcat excavators are different. Our exclusive X-Change® attachment mounting system, quick couplers, clamp mounts, and fingertip controls come standard on a majority of our excavators. You will have multi-attachment functionality–with attachments such as breakers, augers and plate compactors– immediately. You’ll be able to take on more jobs with a Bobcat excavator right now. X-Change System Bobcat’s exclusive system allows you to change attachments quickly. Quick Couplers Auxiliary quick couplers are conveniently located on the boom, keeping them up out of the trench and out of harm’s way. Clamp ready Clamp mounts are integrated into the dipper arm for maximum durability. There’s no welding required to add a clamp. Fingertip Controls The auxiliary hydraulic controls are at the fingertips–providing precision control and low-fatigue operation. Exclusive features include variable flow, allowing you to control the attachment speed or to move a clamp precisely, as well as detent, which provides continuous flow for attachments such as augers and plate compactors. Hydraulic X-Change If you want the most convenient attachment changes in the industry, purchase the optional Hydraulic X-Change®. Activate the hydraulic pins at the flip of a switch; retract for attachment removal or extend for attachment hook up. Install the retainer pins before operating. Attachment capabilities make a big impact on your productivity. When attachment changes are simple, operators are more likely to use the proper-sized bucket and the best attachment for the job. That can mean fuel savings, less time spent backfilling and less wear and tear on your machine. Bobcat Hydraulic X-Change maintains optimal “pin-on” bucket geometry–so that arm and bucket force are not compromised. Retract or extend the hydraulic pins with a switch. 15 Reduce the time it takes to manually check your grade! Magnetically attach a CR600 Laser Receiver on your machine for laser accuracy and increased productivity. Do more than dig! Even if you just want to dig today, tomorrow’s job could demand more from your machine. An auger, breaker, clamp or one of the other sixteen attachments will go a long way to save you time and labor. You can even share some of the same attachments that fit on your Bobcat loaders. This gives you the most versatility for your dollar and improved profitability. Bobcat ® excavators have your business expansion built right in. Nobody builds more compact excavator attachments. Whether it’s breaking concrete, breaking down buildings or drilling tree holes, Bobcat attachments help you take on new jobs and get more use from your machine. e H D C B A 16 Bobcat pioneered the attachment industry– expanding the versatility of its equipment using the same toughness and creative engineering that made the brand famous. With more than sixteen attachments to choose from, it’s not just a digging machine; it’s a versatile tool carrier.

Extendable arm or standard power arm? A lightweight model or a heavy-duty machine? There are many things to consider when choosing an excavator. However, it’s easy to choose the right brand. No matter what features you’re looking for, Bobcat has you covered. The Only One! Bobcat is the only company that manufactures compact excavators in the United States. Obviously, this means better dealer support, parts availability and manufacturer’s support as well as overall quality. A zero tail swing (ZTS) or Zero House Swing (ZHS) excavator gives you more unrestricted rotation and provides greater flexibility if you are constantly working close to objects, or against a wall. Standard Power Arm – If all you are concerned about is digging and lifting performance, then the shorter power arm should be your selection. The power arm gives you maximum breakout force and lifting ability. Optional Arms Bobcat gives you different arm configurations on certain models. Optional arms allow you to configure the excavator based on how you will be using it. 18 Long Arm – If you need more reach and dig depth, equip your machine with the optional long arm (available on certain models). The longer dipper arm reaches farther from one spot to do more work without repositioning the machine. The extra reach, combined with a higher dump height, also makes loading trucks faster and easier. extendable Arm – The extendable arm is basically a telescoping arm that gives you the best of both worlds – power and lifting performance with the ability to extend the machine’s dig depth and reach when you need it. Standard Power Arm retractable Undercarriage Hydraulic Angle Blade The Bobcat angle blade, available on select models, hydraulically adjusts 25 degrees left or right to direct spoil and minimize “trailers” left on both sides of the blade. This capability may expedite grading and backfilling tasks. The Bobcat angle blade also offers a bolt-on reversible cutting edge, blade float and a “dual blade” cylinder design which provides superior protection of the cylinders and fi ttings. The 418 and 323 Bobcat ® compact excavators feature a hydraulically activated retractable undercarriage. Retract the track to squeeze through the tightest access points. Expand it for enhanced lifting and trenching capabilities. Generally speaking, zero tail swing excavators are a little wider than a conventional swing excavator. If your biggest obstacle is gaining access, like squeezing your way into a gate, or maneuvering into a crowded backyard, a conventional compact excavator can take you there.
