The Model 54TR has the popular Geoprobe® 5400 series probe machine mounted to a Model 4115 John Deere, four-wheel-drive, off-road tractor. This machine is small and compact. It easily moves about your job site with its rubber tires. Designed for sampling activities, such as pipeline and refinery work where high volume, shallow sampling is common, the Model 54TR is a solid, dependable machine. We've rented it to customers working within a Rail Road track region and deep into brush and hill terrain.
