Toro's new Tier 4-compliant 5410-D and 5510-D Reelmaster fairway mowers are now available. The Tier 4-compliant 5410-D and 5510-D meet new requirements for lower emissions and reduced environmental impact.Powered by a 36.8 hp Yanmar diesel engine, the new mowers feature direct injection for clean-burning power and improved fuel efficiency, common rail electric system for precise control of fuel injection, cooled exhaust gas recirculation to reduce nitrogen oxide emissions, diesel particulate filter which minimizes particulate matter in exhaust, and Toro's InfoCenter LED display with on-board diagnostics and maintenance reminders.
The new Yanmar engine was selected for these models based on low total cost of ownership, fuel efficiency and intelligent engine technology. See this article for more information.
Direct injection technology has traditionally delivered better fuel efficiency than alternative technologies, Toro says. Although field test data is limited, Toro says it is confident that their new Tier 4 final mowing solutions will deliver improved fuel efficiency for Turf applications.
The Yanmar engines also have a modern, state-of-the-art design with a more robust bottom end, including crankshaft, connecting rods and bearings.
