Day in and day out, you give it your all. So don’t you deserve a truck that’ll work just as hard for you? Cat® Vocational Trucks were designed with that hard work in mind. And with three rugged and reliable trucks in the lineup, you’ll find a Cat Truck to fit whatever application you need to get the job done.

The Cat CT660 — Built for the Work You Do

Delivering all of the power, performance and durability you need, the CT660 is loaded with all of the features and options you want in a next-generation dump truck, concrete mixer, waste carrier or heavy hauler. It’s designed to maximize payloads, drive satisfaction and increase uptime in dozens of applications.

CT660 Exterior Features

When it comes to Cat trucks, quality is always at the top of the list. The new Cat CT660 cab is wrapped with premium aluminum alloy for extra strength and durability. With a sloped Metton hood and a large curved front window, the CT660 offers maximum visibility from the driver’s seat to the ground. For enhanced side visibility, the new vocational truck features heated and lit cowl mounted mirrors integrated with turn signals that can break away to reduce damage impact.

The front bumper and grill consist of three pieces that are riveted and bonded to reduce repair costs if impact was to occur. For added protection, the lightweight composite hood is equipped with TPO fender flairs and is designed with open and close assist strut system. The CT660 set-back axle with 116-inch and 122-inch bumper to back of cab lengths provides an extra tight turning radius for enhanced maneuvering. This truck can be custom built to fit your specifications and preferred body type; it’s available in 6×4, 8×6, 6×6, and 4×4 day cab or tractor configurations. You’ll also find two tow hooks with a standard towing capability of 120,000 lbs. For additional towing capacity, Caterpillar offers an optional draw bar pin at 150,000 lb.

CT660 Interior Features

The spacious interior of the Cat CT660 offers the comfort you would expect from a Cat product. The optimized day-cab features a suspension design for enhanced driver comfort and reduced driver fatigue. The ergonomic design is highly effective at improving driver safety and productivity.  Assembled with a premium sound insulation kit, loud noises won’t be an issue with this cab. Plus, the materials used in the cab were selected and designed for noise reduction.

Leveraging their expertise in design, you’ll find that Cat has optimized the layout of the the gauge for clear visibility through the steering wheel, improved rocker switch panel with large switches and tactile feedback for easy use with or without gloves, and an ergonomic dashboard with a tilted center stack for easy access and storage. But that’s not it for storage. Cat maximized the cab’s space with storage in the door, on the dash and in the overhead compartment for quick access to paperwork or log books. Not only that, the oversized back panel storage and side pockets are perfect for keeping important items within the operator’s reach.

The Cat CT680 — Here for the Toughest Jobs

Stand up to heavy loads, tough jobs and harsh applications and do it all in style with the CT680. It features your choice of two exterior trim levels — L and LG — so you can customize your truck by choosing the features that best fit your style and serviceability needs. Plus, its set-forward axle, parabolic suspension, premium sound insulation and trim and spacious cab combine to set new standards for comfort and ride quality.

Cat® CT680 Vocational Truck Heavy Hauler

CT680 Exterior Features

The Cat CT680 boasts the same great features as the CT660, but more. The sleek and stylish CT680L is decked out with a three-piece Metton hood, three-piece chrome bumper and three-piece chrome stainless steel grille designed with your budget in mind. For brighter visibility, the on-highway truck is equipped with composite halogen headlights and incandescent park and turning lights.

Its sidekick, the eye-catching Cat CT680LG, is outfitted with a one-piece fiberglass hood, three-piece black bumper and integrated fiberglass grille. Sealed-beam halogen headlights and LED park and turn lights are loaded on to the impressive truck for enhanced visibility.

Both models feature the curved, sloped wraparound windshield, available in a one- or two-piece design, as well as large, heated, cowl-mounted power mirrors for an excellent range of vision from inside the cab. The CT680L and CT680LG are both equipped with two removable, frame-mounted tow hooks with 78,000 lb. rating. With a set-forward axle, 124-inch bumper to back of cab (BBC) and rugged exterior construction, the CT680 stands up to heavy payloads and tough applications. It’s available in 6×4 and 8×6 truck or tractor configurations.

CT680 Interior Features

The wide cab design of the CT680 (L & LG) allows for a spacious operator station with ergonomic dash and center stack to maximize safety and reduce fatigue. The CT680 includes the easy-to-use rocker switch panel with large switches and haptic feedback. For additional comfort, choose from multiple driver seat options and adjust the tilt-enabled, telescoping steering column to find the best position for your comfort.

Say farewell to noisy cabs. With a tuned cab air suspension system and premium grade sound insulation, as well as durable routing and clipping wire system, you can enjoy a smooth and quiet ride in the CT680. No matter how hot or cold the day is, get easy access to the HVAC controls and vents positioned for optimum air flow. Want more efficient air inside the cab? Opt in for the Dual External Air Cleaners (DEAC) and achieve efficient air management, even in dirty and dusty applications.

Additionally, the CT680 duo includes Product Link asset and fleet management system so you can keep track of the truck’s productivity and efficiency. Along with the optional Vehicle Infotainment System (VIS), access the trucks navigation software and set truck-specific routing as well as log miles and keep accurate records.

The Cat CT681 — Here to Work as Hard as You Do

Ideal for carrying big loads and complying with bridge load restrictions, the set-forward axle on the CT681 boosts your productivity and features a spacious, ergonomic cab and industrial styling. Mounting attachments is simple with the optional Front Frame Extension, giving you a vocational truck as heavy-duty as your application.

CT681 Exterior Features

You can expect the same high standards found in the CT660 and CT680 Cat on-highway trucks with the latest CT681. From the wraparound windshield to the heated cowl-mounted power mirrors, and down to the illuminating sealed-beam halogen headlights, the CT681 was well designed to meet the needs of owners and operators everywhere. Many compare the durability and dependability to a tank, and that’s because Caterpillar designed it to work hard and last for years.

Don’t be fooled by the comparison; this hauling machine was built to maximize payloads with a weight of about 250 pounds less than a steel cab, thanks to the lighter-weight aluminum alloy cab. This set-forward axle model features 114-inch bumper to back of cab (BBC) and 28-inch bumper to axle (BA) lengths. It’s available in 6×4 day-cab with two tow loops with 78,000 lb rating. For added convenience, the CT681 was strategically designed to improve service accessibility through easier access to key service points and an independent hood to accommodate front end components.

CT681 Interior Features

When you’re in the cab all shift long, you want comfort. With the Cat CT681, that’s what you can expect. Choose from a wide array of driver seat options, including the Cat Comfort Seat. Reduce fatigue with an ergonomically designed dashboard and center stack so you can see everything at a glance without needing to adjust or shift; plus, the leather-wrapped steering wheel is tilt- and telescopic-enabled for a more comfortable driving position.

Just like the other two models, the CT681 has a tuned cab air suspension system, premium grade sound insulation kit and durable routing and clipping wire system which results in a smoother and quieter ride. There’s plenty of room in this spacious cab for storage in the side compartments, back-panel and oversized side pockets. This well-illuminated interior combined with standard and convex mirrors improves overall safety inside the cab.

As an added bonus, Cat Product Link comes standard with the CT681 model. With the standard component, owners and operators can track machine performance and log fuel usage, costs, location history, idle time and much more. Add the Vehicle Infotainment System to set travel and routing information as well as to log miles, time and miles per gallon so you can keep accurate records for billing and tax purposes.

CAT-CT680-Engine-Performance-Power

All are Powerful Under the Hood, too

No matter which one fits your needs best, all of the Cat Vocational Trucks feature an ideal combination of power and performance under the hood. Each truck is powered by a CT Series Vocational Truck Engine, designed specifically for vocational applications, with ratings from 365-475 hp (CT660) to 410-475 hp (CT680) and 365-430 hp (CT681).

In addition, all three trucks feature power take-off (PTO) to drive engine power to your attachments — the CT660 and CT680 have rear power take-off and the CT681 has front engine power take-off — and are designed to meet emissions standards with a highly effective Selective Catalytic Reduction (SCR) solution, featuring upgraded in-cylinder technology and a proven after-treatment system.

Shift into Work-Mode, Automatically

Performance-matched with the CT Series Vocational Truck Engine is the Cat CX31 Automatic Transmission, designed to deliver rugged durability, fuel economy and smooth shifting for optimum power and efficiency. It features the industry’s highest power-to-weight ratio and live power take-off options with two side PTO locations and a Cat exclusive high-output rear PTO. But if you’re looking for a manual option, there are other options available including the Ultrashift® Plus Vocational Transmission built by Eaton.

Final Thoughts on the Cat CT660, CT680 and CT681

All three trucks were built to work hard for a wide array of applications and deliver reliable performance, power and productivity. Cat factored in hundreds of hours of customer input and loaded it with the features and options operators need for today’s demanding jobs. Made with a light-weight aluminum alloy body, you can maximize productivity without compromising durability and dependability on the worksite.

Expect comfort and safety from each tank-like vocational truck. The ergonomic designs, spacious cab and comfortable operator station will make you never want to leave the cab. The enhanced rocker switch panel with larger switches and haptic feedback allows for use with or without bulky work gloves.

The Cat CT Truck Series was designed to leave an impression; on the road or in the dirt. No matter where the job takes you, expect heads to turn for the striking front grille, sleek aerodynamic lines and, of course, the Cat emblem. The all-around heavy hauler of all three models is here to work for you.

You can custom build any three of these trucks to fit your specifications and put it to work right away.
