About Us

It was in 1954 that a shop foreman names Ruben Bentz was left jobless after the company he had worked for was bought out. Turning adversity into opportunity, he decided to establish his own business in tractor parts and service. This business was born in the west side of Stockton, California in a livery stable.

In time Ruben suffered a stroke. It was at this point his son took over the business and made the decision to move the company to another location in west Stockton. This is where the business has remained to this day.
