Engine
| Engine Model | Cat® C13B |
| Note (1) | Advertised power is tested per the specified standard in effect at the time of manufacture. |
| Note (2) | Advertised power is tested at 1,800 rpm. |
| Note (3) | Net power available at the flywheel when the engine is equipped with alternator, air cleaner, muffler, and fan at minimum speed. |
| Note (4) | Net power when the fan is at maximum speed is 274 kW (367 hp) per the SAE reference conditions. |
| Note (5) | Meets U.S. EPA Tier 4 Final, EU Stage V, Japan 2014, and Korea Stage V emission standards. |
| Note (6) | Diesel exhaust fluid (DEF) used in Cat SCR systems must meet the requirements outlined in ISO 22241-1:2006. ISO 22241-1 requirements are met by many brands of DEF, including those that carry the AdBlue or API certifications. |
Sound Levels
| Note (1) | The declared dynamic operator sound pressure level is 70 +/- 1 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. |
Body Plate
| Type | High strength Brinell HB450 wear resistant steel |
Standards
| Brakes | ISO 3450:2011 |
| Cab - FOPS | ISO 3449:2005 Level II |
| Cab - ROPS | ISO 3471:2008 |
| Steering | ISO 5010:2019 |
Turning Circle
| Turning Dimensions - Steer Angle - Left/Right | 45° |
| Note | Dimensions are for machines equipped with 23.5R25 tires. |
Steering
| Lock to Lock | 4.75 seconds @ 60 rpm |
Optimal Loader/Truck Pass Matching
| Hydraulic Excavators: 350/352 - Passes | 5-Apr |
| Hydraulic Excavators: 336 - Passes | 6-May |
| Wheel Loaders: 972/972 XE - Passes | 4-Mar |
| Wheel Loaders: 966/966 XE - Passes | 4 |
| Wheel Loader: 962 - Passes | 5-Apr |
| Wheel Loader: 950 - Passes | 5 |
| Note | An optimum system match gives you a major productivity advantage. The 730 is an excellent match for the Cat 350/352 and 336 Hydraulic Excavators and Cat 972, 966, 962, and 950 Wheel Loaders. Having matched loading and hauling tools results in increased production and lower system costs per unit of volume moved. |
