A powerful Tier 4 diesel delivers robust, high-power performance with an efficient fuel system — for reliable start-ups, long component life and low noise and vibration that keep the work comfortable.

Every 4500-platform tractor is turbocharged for consistently strong performance and impressive low-end torque that holds up even at higher altitudes.

The 3-range HST makes operation easy with fast, simple direction changes — ideal for front-loader work, mowing and clearing brush. Work in low, medium or high range (each with infinite speed and torque variation); you only stop to switch range. A simple twin-pedal layout (one pedal forward, one reverse) keeps direction changes quick and suits operators of every experience level.

A tight turning radius lets you work in close to trees, buildings and other obstacles for effective mowing, tilling and more.

Steering brakes help maintain a tight turning radius — nearly pivoting the tractor on its inside wheel — especially handy between buildings, in pens and barns, or around trees.

Competitive drawbar towing power and force handle heavy implement towing with confidence.

The drawbar stows away when not in use — just pull the pin, turn it around and store it on the tractor.

Telescopic links accommodate a wider range of implements and hitch configurations and make connections easier, allowing precise adjustment.

PTO cruise holds rpm at your preferred setting even as load changes, so powered implements run at a consistent speed — improving efficiency and performance when the job needs steady, continuous power.

With an independent PTO you can engage or disengage the PTO without stopping — just flip the switch and go to work, no full stop and no clutch needed.

An adjustable hitch adds towing flexibility and convenience.

Side mirrors give a wider field of view for monitoring both sides of the tractor and the surrounding environment.

Standard four-wheel drive powers all four wheels for the traction tough jobs demand.

Three tire types match your work for the right blend of reliability, traction and ride quality:

• Turf: a gentler tread that minimizes disturbance on lawns and established landscaping.
• Industrial: wider tread than agricultural and deeper lugs than turf, for great all-condition traction.
• Agricultural: deep, self-cleaning lugs for traction in soft soil and mud and more pull when towing.

A sealed cab with a powerful, efficient heat and air conditioning system gives all-weather comfort in any season. Dampening rubber cab mounts isolate engine and transmission vibration and cut noise, a cup holder and 12-volt power port add convenience, and a heated rear window clears ice and snow for a clear view.

Eight vents throughout the cab (four in front of the operator and two on each side) plus plenty of air power let you reach a comfortable temperature quickly in any weather.

Large, wide glass panels, a tiltable rear window with rear defrost and only four slim support columns give panoramic, low-obstruction visibility while you work.

Rubber isolators between the mainframe and cab minimize vibration passthrough for a comfortable ride on long workdays.

The cab comes ready for the optional Bluetooth radio, so you can connect compatible devices for on-the-job entertainment.

The engine is designed to run with low noise and minimal vibration to keep you comfortable and focused on the task.

An additional rear window to the 3-point hitch lets you hook up implements and monitor work performance without frequently stepping out of the cab.

Controls, gauges, switches and buttons are thoughtfully laid out for ease of use, with an illuminated dashboard you can read in any light.

The joystick is easy to reach for loader work and positioned to maintain visibility, with a molded grip that makes the front loader respond intuitively to your command.

A comfortable, adjustable seat accommodates operators of all sizes and minimizes fatigue so you can stay in the tractor longer.

Open the second door for easier jobsite communication or enhanced visibility.

When grading, raking or traveling longer distances without direction changes, engage cruise control from a conveniently located dash switch to hold a consistent speed with less input.

Power steering adds near-effortless control, and the tilt function lets you set the wheel to the most comfortable position.

The linked pedal raises engine rpm as you engage the travel pedal for intuitive front-loader control and easier operation on a variety of jobs. At the push of a button the travel pedal and throttle link, and it works in forward and reverse.

Bright headlights illuminate the job for high visibility in evening work and other low-light conditions.

The radiator screen protects the radiator from debris and slides out for simple cleaning and replacement.

Two taillights make the tractor more visible to others, especially in low light or at night.

A tough, reliable built-in sun visor shields your eyes from bright sunlight for easier work on bright days.

Four work lights illuminate the front and rear of the tractor to keep you productive long after sunset or before sunrise.

Side view mirrors provide a wider field of view for enhanced visibility on both sides of the tractor and the surrounding environment.

Raise and lower the lower link arms with a height-control lever at the rear of the tractor — saving trips in and out of the cab to attach implements.

A rubber floor mat dampens vibration through the floor for a more comfortable day's work.

A rear-view mirror helps you keep better track of your surroundings.

Robust Tier 4 diesel power with an efficient fuel system means reliable start-ups, long component life and low noise and vibration for comfortable work.

The flip-up metal hood gives convenient engine access while protecting the engine and components from dirt and debris.

Included with the optional front loader, the heavy-duty brush guard protects the tractor's front end from debris, branches and other material.

A heavy-duty polymer fuel tank maintains fuel integrity and eliminates rust-related contamination.

Bobcat built its brand on quality equipment backed by reliable local dealers with service and parts availability that's second to none — like Carleton Equipment, Michigan's authorized Bobcat dealer with 7 locations, helping keep machines running for decades.

All daily checks, engine fluid fills and filters are located on one side of the engine, making it convenient and easy to keep your tractor running smoothly with minimal effort.

No side panels to remove — just lift the air-assisted hood, which opens nearly perpendicular to the engine compartment for best-in-class access to the major service points. Plus:

• Easy-to-fill windshield washer fluid
• Easy-to-access cabin air filter
• Quick-release radiator screen

A standard toolbox on the back of the cab, underneath the window, keeps the small tools you need at the ready.

With leading lift capacity and height, the optional front loader is a must-have for digging, dirt moving, loading and carrying. It detaches and stands freely on its own so you can quickly drive into or out of it, a standard level indicator reduces spillage and keeps the load even through the lift cycle, and float lets it follow ground contours. The standard quick-attach system makes mounting attachments fast — line up the mounting plate and lower the levers to lock securely.

A rear remote hydraulic valve adds attachment versatility by controlling and positioning many implements. One pair of couplers comes standard, and a second pair can be installed as an accessory.

The flip-up PTO guard opens up room for easier PTO connections while providing protection during operation.

An optional mid-mount PTO powers mid-mount implements such as mowers, snowblowers and sweepers, expanding the range of tasks the tractor can handle.

Quick-pin sway bars secure and remove with ease to save time and effort on every implement change.

Angled lower lift arms make implement hookup quick and easy.

Telescopic links accommodate a wider range of implements and hitch configurations and allow precise connection adjustments.

Hydraulic draft control senses when hard ground exerts additional force, or "draft," and automatically adjusts implement height to maintain a consistent load — minimizing manual intervention, reducing fatigue and boosting productivity.

Bobcat gives you access to a world of implements and attachments — moving snow, digging post holes, caring for animals and more — so with the right tractor and the right attachment, there's virtually no task beyond your ability.
