Professional services to support your plant equipment.

Text description


Zimmerman-McDonald has over 150 years of combined experience in the purchasing and selling of both new and used machinery and equipment.  We constantly keep attuned to the industry and the market for machine tools. We have two Certified Appraisers on staff (certified by the Association of Machinery & Equipment Appraisers – AMEA).  Our Appraisers conform to the association’s standards of professional appraisal ethics and practices. Our reputation, experience and professionalism have provided us the opportunity to advise financial institutions, insurance companies, attorneys, as well as public and private corporations.


In addition to purchasing your surplus machines, we offer a consignment selling program to help you realize the most return on your equipment. We will provide you with the market value of your machinery and will globally advertise it at our expense.  All we ask of you is that you allow us a 90 day period to promote and market your machinery. We have been providing this alternative to the process of outright selling for over 25 years and have many satisfied customers.


Zimmerman-McDonald is an expert resource for all types of machine tool and equipment liquidations. We also purchase complete plant facilities, and either liquidate them, or dispose of the property through auction sales. Whether you have a facility with just a few machines, or a complete manufacturing facility with 1000’s of tools, we can provide you with alternatives to realize the most from your machinery disposal. Call us today and let us structure a program that best realizes your needs.


Do you remember why you bought a new machine in the first place? Maybe it was for reduced setup time, dependable up time, or higher production capability than a used machine offered. Whatever the reason, you knew what you were getting when you bought new over used, and the decision made more sense.
With over 125 years of experience, we can help keep your “new” machine running ‘like a new machine’ for an extended period of time. With our experience, we understand what is required to keep these machines performing like new.

Often once a machine is purchased, people get busy and maintenance becomes an after thought until that unfortunate time arises…machine problems and downtime. No matter how high the quality of a machine, problems will develop without proper maintenance. Lack of maintaining machines can grow into considerable costs and excessive downtime.

We have a well-established Preventive Maintenance Program that has provided many customers with years of uninterrupted performance and high tolerance. We can provide a factory-trained technician on a six-month or yearly basis: to inspect your machine(s), perform required maintenance, and adjust your machine back to original specifications as required. Once a year it is also strongly recommend that fluids be changed so that your machine will continue to perform at its highest level.

When is new no longer new? With preventive maintenance we provide you with the peace of mind that new can last for a very long time.

Mechanical and Technical Support

All Zimmerman-McDonald technicians are factory trained. We know hydraulics, electronics, mechanics, and controls. We can install your machine, and we have the capability to train your staff on proper operation of the machine.  We provide warranty service, technical support, and preventive maintenance services.

We have a computerized work schedule so we know where and when our technicians are scheduled for assignments; so that we can provide the most efficient service possible. A complete customer and machine database is updated with each sale and service call. We track all work, warranty information, and requirements associated with each machine. This provides a source for all equipment purchased and all work that was ever performed on your machine. Should a part problem ever develop with your machine, we stock over $60,000 in parts to provide immediate solutions to your problem.

Our philosophy is simple: Why wait 24 hours to fix something when it can be fixed today?
