Buying a used diesel or natural gas generator does not mean you give up quality for a lower price. We have trained technicians who maintain the health of our entire used generator fleet. Before we deliver your purchase, we perform a careful inspection and load capacity testing. As soon as your unit arrives, it is set to power your project or facility at full strength.

Our Selection of Used Generators

MacAllister Used Power Systems has a wide selection of preowned diesel and natural gas generators. Before listing units, we carefully inspect them and perform a load capacity test to check performance. For added peace of mind, you can opt for certified used models, which undergo a more thorough inspection and come with extended warranties. We also stock all the add-on products to get you up and running.

Many of our generators are manufactured by Caterpillar. Cat® engines have a legacy of fuel economy, safety and long service life. Plus, they are easy to maintain and simple to use, making used Cat generators a sound choice for your power needs. We also offer used generators from Cummins, Detroit Diesel, Olympian™ and other big-name manufacturers.

Used Portable Generators

Trailer or skid-mounted generators are compact and easily movable. You can place them around multiple points on your site, or transport them between several locations. Our mobile generators can suit your construction or emergency response operations and prepare you for any situation, including powering operations with limited access to grid power.

Used Standby Generators

A durable standby generator can provide kW ratings ranging from 50 kW to 3,000 kW and beyond for various industrial power applications. Our larger preowned generators often have sound-attenuated containers, providing quiet operation. Their sturdy builds can spend years in the elements with low maintenance requirements.
