    The 730 meets Tier 4 Final and Stage V emission standards.

    Note (3)

    The net power advertised is the power available at the flywheel when the engine is equipped with alternator, air cleaner, muffler and fan at minimum speed.

    Note (2)

    The power ratings apply at rated speed of 1,800 rpm when tested under the conditions for the specified standard.

    Note (1)

    The references to Tier 4 Final/Stage V include U.S. EPA Tier 4 Final, EU Stage V, Japan 2014 (Tier 4 Final), and Korea Tier 4 Final emission standards.

    Note (5)

    DEF used in Cat SCR systems must meet the requirements outlined in the International Organization for Standardization (ISO) standard 22241-1. ISO 22241-1 requirements are met by many brands of DEF, including those that carry the AdBlue or API certifications.

    Note (4)

    Net power when the fan is at maximum speed is 254 kW (341 hp) per the SAE reference conditions.

    Optimal Loader/Truck Pass Matching

    Wheel Loaders: 972M/972M XE - Passes



    An optimum system match gives you a major productivity advantage. The 730 is an excellent match for the Cat 349F and 336F Hydraulic Excavators; and Cat 972M, 966M, 962M and 950M Wheel Loaders. Having matched loading and hauling tools results in increased production and lower system costs per unit of volume moved.
