Features & Benefits
HEAVY-HAULING CAPACITY
The CT681’s set-forward axle, rugged design and industrial styling make it ideal for hauling heavy loads or working in extreme conditions. Aluminum alloy cab construction reduces overall weight for maximum payloads.
ATTACHMENT-READY DESIGN
Our integral Front Frame Extension (FFE) option makes it easy to mount attachments like snow plows, hose reels, winches and hydraulic pumps. Mixer installation is simple thanks to vertical tie-in plates mounted behind the cab.
SHIFT-LONG PRODUCTIVITY
Comfortable drivers are safe, productive drivers. The CT681’s wide, spacious cab is filled with ergonomic details to reduce fatigue and thoughtful features to enhance driver comfort, all shift long.
SAFER DRIVING
Our ergonomically designed dashboard and centre stack layout give drivers complete command and control. All controls, levers, switches and gauges are positioned to maximize safety and minimize fatigue, so drivers can stay focused on the job at hand.
SMOOTH, QUIET RIDE
Our tuned cab air suspension system, premium grade sound insulation kit, and durable routing and clipping wire system dramatically reduce vibration and cab noise.
VOCATIONAL-SPECIFIC POWER
Under the hood, the CT681 is powered by a Cat CT Series Vocational Truck Engine with ratings specific to vocational truck applications and a horsepower/torque combination to tackle the toughest jobs.
AUTOMATIC SHIFTING
Performance-matched with your engine to deliver rugged durability, smooth shifting and optimum power, the Cat CX31 Automatic Transmission will help you maximize your CT681’s uptime, fuel economy and productivity.
UNMATCHED SUPPORT
Your Cat dealer not only offers bumper-to-bumper service, but also can help you order the exact truck you need with expertise on custom options ranging from transmissions to suspensions and axles.
