The Cat® 740 raises the bar for operator comfort and control. Its redesigned, world‑class cab is built to deliver a smoother, smarter, more intuitive experience. With upgraded controls, built‑in transmission protection, hoist assist, advanced automatic traction control, stability‑assist rollover warnings, and an ECO mode that cuts fuel use, the 740 is engineered to keep productivity high and operating costs low.
| Engine Model | Cat® C15 |
| Note (1) | Advertised power is tested at 1,700 rpm. |
| Note (2) | Advertised power is tested per the specified standard in effect at the time of manufacture. |
| Note (3) | The net power advertised is the power available at the flywheel when the engine is equipped with alternator, air cleaner, aftertreatment, and fan at minimum speed. |
| Note (4) | Net power when the fan is at maximum speed is 327 kW (439 hp) per the SAE reference conditions. |
| Note (5) | Meets U.S. EPA Tier 4 Final, EU Stage V, Korea Stage V, and Japan 2014 emission standards. |
| Note (6) | Diesel exhaust fluid (DEF) used in Cat selective catalytic reduction (SCR) systems must meet the requirements outlined in ISO 22241-1. Requirements are met by many brands of DEF, including those that carry the AdBlue or API certifications. |
| Note (1) | The declared dynamic operator sound pressure level is 72 dB(A) when ISO 6396:2008 is used to measure the value for an enclosed cab. The measurement was conducted at 70% of the cooling fan’s maximum speed. The sound level may vary at different cooling fan speeds. The measurement was conducted with the cab doors and the cab windows closed. The cab was properly installed and maintained. |
| Note (2) | Hearing protection may be needed when operating with an open operator station and cab or when not properly maintained or with doors/windows open for extended periods or in noisy environments. |
