Customer Value Agreements = Good Value

By properly maintaining your equipment with a Customer Value Agreement (CVA), you can maximize the up-time of your equipment by identifying equipment issues before they cause failure - saving you time and money. CVAs typically include on-site preventative maintenance services performed to factory specifications by our Cat certified technicians. Our experienced service team will customize your CVA to achieve a cost effective maintenance solution that will meet the specific needs of your business.

Hawthorne Cat is the one-stop shop for outstanding service and support for your equipment needs. We are a full service provider for bulk and packaged fluids for all Cat and non-Cat makes and models.

Customers can request a complimentary S.O.S. Oil Analysis for all major oil-lubricated systems of your machine (engine, transmission, hydraulic system, and final drives) and a detailed walk around inspection (technical analysis). Our Conditioning Monitoring Analysts will provide you with a detailed report with recommendations to ensure your equipment is properly maintained to maximize the up-time of your machine.
