Your Source for Used Generators

Whether you want a generator for reliable prime power or to add to your contingency plan, we have the solution. We will work with you to provide an energy-efficient, low-hour generator that can help you meet industry compliance rules or serve your clients.

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.

The Used Generators We Offer

You’ll find many options that are sure to handle your electrical power generation requirements. Our inventory has units with a range of kilowatt ratings and engine setups. Finding the right size and output is as simple as asking one of our product experts. We are always refreshing our supply to offer the best deals on the strongest generators on the market.

As the authorized Cat® dealer in Indiana, MacAllister Power Systems has many pieces of pre-owned equipment 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 and other big-name manufacturers. Whatever the make, we have the training to install and service your purchase. Our dealerships also stock all the add-on products and accessories to get you up and running.

Used Portable Generators

A huge benefit of our trailer-mounted generators is how compact and easy to move they are. You can place them around multiple points on your site, or transport them between several locations. Our portable generators can suit your construction or emergency response operations and prepare you for any situation.

Used Standby Generators

For hundreds or thousands of kilowatts, go with a durable stationary generator. Our larger pre-owned generators are often held in sound-attenuated containers, providing quiet, constant operation. Their sturdy builds can spend years in the elements with low maintenance requirements, ready to power on at any time.

Get the Best Value by Shopping at MacAllister Power Systems

It’s our goal to make your used generator investment the most affordable choice for your organization. We provide equipment financing with custom plans so you can buy better equipment on your terms.

Our locations throughout Indiana have an experienced team of representatives and engineers in place. With our more than 75 years of generator expertise, MacAllister is here to be your trusted partner in keeping the power on. If we do not have the generator you want, there is a chance MacAllister can find the right unit on the nationwide network of Caterpillar dealers.
