Image Victa Mustang lawnmower with Eco Torque engine, 2007

TLF ID M000369

This is a 2007 Victa Mustang lawnmower. It has a grey alloy chassis and a black-and-grey plastic catcher. 'VICTA' is embossed in black on each side of the catcher and in between the front wheels. The mower is operated by a Victa VEX60 two-stroke Eco Torque petrol engine. The engine cover is black-and-red plastic. The mower has a fold-down handle with air-intake filter and controls on one side. The cutting width is 48 cm from edge to edge and there are four black rubber-and-plastic tyres.

Educational details

Educational value
  • This lawnmower with Eco Torque two-stroke engine is the first attempt by Victa to address engine emissions in the design and marketing of its mowers. With this mower the company made a small change to the existing engine technology to achieve emission reductions while maintaining robustness and reliability. The lawnmower also includes a black plastic mulcher that can be attached to the main body when the catcher is removed.
  • The new engine is the result of several years of research and technical development by Victa and University of Technology, Sydney, in response to government pressure to reduce small-engine emissions and improve urban air quality. It represents the complex relationships between government, industry, technology and culture in achieving environmental outcomes.
  • Through simple modifications to the engine block, carburettor and muffler, harmful emissions (carbon monoxide, hydrocarbons and nitrogen oxides) have been reduced by 30 per cent and fuel consumption by 20 percent compared to the earlier Victa two-stroke engine. While this engine does not yet meet strict US regulations, Victa is continuing its research and development to further reduce emissions and meet equivalent regulations that may be introduced in Australia. The model pictured will potentially become rare if such regulations are introduced in Australia.
  • This mower was assembled in 2007 at the Victa assembly line at Moorebank from components manufactured elsewhere. Approximately 90 per cent of the components were manufactured in Australia. The Eco Torque engine was manufactured by Century in Adelaide.
  • Until recently Australian emission-control strategies have focused on major polluters such as industry and motor-vehicle engines. Consequently, emission-reduction technologies for lawnmowers and other gardening implements have only recently become a design consideration. As a result the emissions from an unregulated small engine can contribute more emissions per hour of use than a much larger car engine that has emissions-control technology.
  • Domestic lawnmowing accounts for 10 per cent of the total anthropogenic volatile organic compounds (VOCs) in the greater Sydney metropolitan region on a summer weekend. VOCs contribute to ozone and smog formation in summer. Because of the combustion of oil, lawnmowers also emit high levels of particles. The National Pollutant Inventory indicates that lawnmowers produce air toxins.
