Compact Excavators
180o
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,
superior visibility and reduces repositioning for work in tighter spaces. A tracked undercarriage gives you additional benefi ts like superior fl otation compared to a wheeled machine. Also, compact excavators use less fuel and can be hauled with lighter, more fuel-effi cient trucks, keeping your hourly costs down.
BUrIeD UTILITY
Independent boom swing provides offset diggingcapabilities, 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
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.

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.
Greater flexibility
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.

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 thatdetermine the true performance of the machine. Whether it is a closed center valve,
High-effi ciency, 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.
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 fl ow to all functions. This delivers smooth operation without sacrifi cing cycle times. Bobcat excavators are both smooth and fast, so you can get your work done more quickly.

MOre PreDICTABLeThe 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.
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.
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 Horsepower
7
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.
We pack in more horsepower than other manufacturers–producing excavators withsuperior 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. HP to Weight
Bobcat® excavators have more engine horsepower than other brands of the same size.

Hydraulic HorsepowerBy having more engine horsepower, Bobcat excavators generate more hydraulic horsepower where it counts – under maximum fl ow and maximum pressure. This allows the excavator to utilize fl ow at higher pressures, which translates into faster cycle times under load. Simply put, they dig stronger and faster.
FastTrack Drive SystemFastTrack™ drive system, the first and only all-hydrostatic 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.
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.

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.

Panoramic Serviceability
10
Bobcat makes it easy to fi nd 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. black-and-white TV. 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, well-protected grease cylinder fi tting. What does panoramic serviceability mean? Preventative maintenance gets completed, reducing operating costs and improving your bottom line.

Bobcat pays as much attention to operator comfort as it does to digging performance. 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 fl ow where you need it most. Other elements such as radio-ready cabs and fi ngertip-controlled auxiliary hydraulics all add up to increased operator comfort.
Bobcat believes that there is a direct relation-ship between operator comfort and productiv-ity. If you can comfortably stay in the seat longer, you will be able to get more work done.

Exclusive to Bobcat is the In-Track Swing Frame, which allows you to get closer to your work. Our swing castings and cylinders stay within the tracks when offset digging – giving you the ability to truly dig fl ush 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.

Hydraulic X-ChangeIf you want the most convenient attachment changes in the industry, purchase the optional Hydraulic X-Change®. Activate the hydraulic pins at the fl ip 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 backfi lling 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.
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 fi ngertip 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 SystemBobcat’s exclusive system allows you to change attachments quickly.
Quick CouplersAuxiliary quick couplers are conveniently located on the boom, keeping them up out of the trench and out of harm’s way.
Clamp readyClamp 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 fi ngertips–providing precision control and low-fatigue operation. Exclusive features include variable fl ow, allowing you to control the attachment speed or to move a clamp precisely, as well as detent, which provides continuous fl ow for attachments such as augers and plate compactors.

Selecting a Model
Standard Power Arm
Optional ArmsBobcat gives
you different arm confi gurations on
certain models. Optional arms allow you to confi gure
the excavator based on how you will be using it.
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.
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.
Conventional house or Zero House Swing? Extendable arm or standard power arm? A light-weight 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.
A zero tail swing (ZTS) or Zero House Swing (ZHS)
excavator gives you more unrestricted rotation and
provides greater fl exibility if you are constantly work-
ing close to objects, or against a wall.
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.

*Always check with local and state towing regulations.
How low can you go? Bobcat covers a wide range of digging depths
for a wide range of job possibilities—from fi ve feet to nearly fourteen feet!
Bobcat excavators deliver the operating weight you need to
perform, and they’re easy to tow. Depending on the
model, a half-ton or two-ton truck may
do the job.
retractable UndercarriageThe 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.
Hydraulic Angle BladeThe 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 backfi lling tasks. The Bobcat angle blade also offers a bolt-on reversible cutting edge, blade fl oat and a “dual blade” cylinder design which provides superior protection of the cylinders and fi ttings.
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.
