Used Construction Equipment


From the biggest job to the smallest, your choice of equipment is one that will have a significant impact on your productivity, your operating costs and, ultimately, your bottom line. Choosing a machine that's reliable, fuel-efficient and suited to the task at hand is a key consideration, whether you're building a home, landscaping a property or repairing our region's infrastructure. Whatever the task, there's a Cat® machine for the job. Cat equipment has a longstanding reputation as an industry leader when it comes to fuel efficiency, on-the-job reliability and overall performance. For many operators, however, buying new isn't an option. With an extensive inventory of construction and paving equipment for sale, Altorfer Cat has a complete equipment solution for any budget.   Contact Us


Altorfer Cat is the only authorized Cat construction equipment dealer serving eastern Iowa, northern Missouri, and central Illinois. When you need to buy a tractor, excavator or wheel loader, we are the only place carrying the latest equipment from the legendary manufacturer. We're also the only place to back up its used inventory with factory-authorized service and diagnostics. This means you can shop with confidence, whether you are buying new or used. Our used inventory consists of a wide range of low-hour, well-maintained machines, all of which can be counted on for years of exceptional value, performance, and reliability. Buy a dozer or excavator and equip it with a work tool from our extensive used inventory for additional productivity. If we don't have the machine or accessory you're looking for in stock, there's a good chance we'll be able to source it from our nationwide network of dealer partners.

Buying used construction equipment is the best way to maximize your purchasing dollar while still getting a machine that will deliver all the advantages Cat is known for. Often, used equipment by Cat or an allied brand will deliver better long-term value than a similarly priced new machine by a lesser manufacturer. Particularly when backed by our exceptional long-term service and support, you can't go wrong when you buy a used dozer, buy an excavator or buy a backhoe loader from MO's Altorfer Cat. We'll be there for as long as you own your purchase to provide service support, including preventative maintenance and emergency repairs from our fleet of mobile technicians. An extensive OEM parts inventory means we can source replacement items, typically within 24 hours of receiving your order. And with exclusive access to diagnostic programs such as the S.O.S. Fluid Analysis protocol, keeping your purchase in the best shape possible is easy.
