Groff Tractor maintains a fleet of service trucks to provide on-site service for both repairs and routine maintenance. Our trained, certified technicians are dispatched to your job site to perform maintenance activities recommended by the equipment manufacturer at specified intervals. We can schedule these maintenance procedures when your machines are idle to optimize your equipment productivity.


Wireless monitoring systems automatically collect and transmit wireless data about your equipment. All data can be accessed through the internet and integrated into your business systems. You can also allow outside parties to access your equipment data.

Groff Tractor can remotely monitor your machines when an AGL, SiteWatch, or Topcon system is installed. We’ll let you know when we receive any alerts for operation problems. Sometimes we even spot a problem before your operator is aware of it. We can diagnose repairs through our systems and come prepared to your site with the proper parts and tools to minimize your downtime.


When one of your machines is down, you can count on us to come to your job site to repair your equipment as quickly as possible. We understand that you might have a problem on a weekend or evening, and our technicians are available whenever you need us. With 15 locations in central and western Pennsylvania, Maryland, Delaware, and New Jersey, Groff Tractor heavy equipment technicians can respond quickly to your emergency and help you reduce costly downtime.
