I think Paul has been Pushing that Model
You had 8 motors blow up in 12 months? That seems a little crazy, do you do any preventative maintenance? Briggs is very good about replacing things if they are a legitimate manufacturing defect.
I have had the main bearing blow the back out of two motors, one was our fault, one was Briggs. Briggs replaced both without issue. Kohlers are also great motors and I dont think you can go wrong with Honda either.
Also....Scott, how many employees do you have and how many trucks are you running, 24 machines in service at once is quite impressive!
27 trucks and 42 employees.
