The implementation date for EPA Phase 3 (Class 2 Engines) is rapidly approaching. This mandate has equipment manufacturers carefully considering which engines to offer. Since your's is the only opinion that really matters, I'd like to hear what all of you think regarding Briggs Vanguard and Kawasaki (which in our opinion are both great commercial engines). First- here are some of the positives and negatives for each side. Sizes Available: Both Briggs (Vanguard) and Kawasaki are elininating all (mid-sized vertical-shaft) commercial-class engines under 16HP (14 Vanguard is on the way out). A 16HP appears to be emerging as the only Pro-class engine choice for commercial walk-behinds. Origin: Vanguard is built in Japan, but owned by an American company. Profits stay in the U.S. Kawasaki is built in America, but owned by a Japanese company. Profits go to Japan. Service Network: Briggs has ~18,000 dealers in the U.S. Kawasaki has ~4,500 Warranty: Briggs Vanguard- 3 years, Unlimited Hours Commercial-Use Kawasaki- 2 years, Unlimited Hours Commercial-Use Parts: Briggs repair parts are generally less expensive than Kawasaki. Price: Kawasaki and Vanguard engines are generally the same price (no effect on the final product price). Design: Kawasaki engines are a totally new design from the crankshaft-out. Technically sophisticated with an outstanding list of features, but unproven in the field. Vanguard is an established design with a proven track-record. So please tell us- When it comes to a commercial walk-behind, what is your choice? 16HP Briggs Vanguard or a 16HP Kawasaki FX?
