Choose the motor that will work best within your operation.


The standard gasoline motor is 23.5 hp.  This electric start motor is durable and reliable, and will serve you well day after day.


A 25 hp diesel motor is optional.  This motor gets better fuel economy than the gasoline motor, and is convenient in most yards and quarries where diesel fuel is usually more readily accessible.


A 20 hp electric motor with panel is optional.  It is the most reliable and efficient motor system.  The system requires a minimum of 220 single phase power.  Because power requirements vary by customer the electrical panel is built to your power requirements.


A combination electric and gasoline, or diesel, motor system allows for more versatility, and ensures the use of the most efficient power source available.
