|Da Vinci code for the yard
(NAPSI)—An idea the Renaissance genius Leonardo da Vinci had back in 1490 could make a difference in how well you can keep your lawn looking today.
The idea was that of a continuously variable transmission (CVT). The basic concept is one of elegant simplicity, involving the use of a drive belt and two pulleys to transfer engine speed to the drive components across an infinite number of speeds. A popular part of many snowmobiles, motor scooters, water Jet Skis, cars, farm tractors and bulldozers, this can be pretty handy for anyone who uses lawn tractors, snow throwers or self-propelled, walk-behind lawn mowers as well. The benefits of using CVTs over more traditional hydrostatic transmissions include greater operating efficiency and maintenance-free operation since they have fewer moving parts to break or wear out.
That’s why many people are asking about the transmission on the equipment they may buy and why General Transmissions, a global leader in lawn care transmissions, uses a modern, sophisticated version of the concept in the automatic transmissions it creates. These are considered extremely reliable, are factory tested to withstand an operating temperature of 258° F, and have been proven in rugged field testing to be virtually impervious to water, rocks, sticks and other lawn debris. A unique safety feature is that the parking brake is applied automatically whenever the machine is in neutral position and manually disengaged by the operator by selecting forward or reverse.
