Surface to Surface Inc. has now made a change to the Gas engines that are used on our mixing systems.
Subaru/Robin has announced that as of September 2017 it is discontinuing its line of small engines.
As quality products are our main goal, not just any Gas motor will do. After extensive research and discussions with different manufacturers Surface to Surface has chosen to go with the Briggs & Stratton Vanguard Series motor on there M4, M750 and M1500 series Gas Mixing Systems.
The B&S Vanguard Series motors with a cast sleeve, low oil warning light and a ball bearing ( Not a bushing ) on the PTO cover makes this motor a excellent replacement for the Subaru/Robin engine that has been used for the last 15 years.
