Follow the link for a recently published edition of the Dutch professional journal about public green areas called “City and Green” which brought the increasingly important problem of vibration on a lawnmower forward.
Exposure to whole-body vibration and hand/arm vibration may cause the widespread recognized industrial disease “Hand-Arm Vibration Syndrome” (HAVS) which is a disorder that affects the blood vessels, nerves, muscles and joints of the hand, wrist and arm caused by continuous use of vibrating machinery. In a world with increasingly stringent safety requirements for workers, as in many European countries, employees are allowed to use a lawnmower no more than a few hours a day, depending on the vibration exposure.
Reducing vibration by mower manufacturers is technically possible of course, but the current market situation doesn’t allow this. In other words, municipalities and contractors often have to deal with shrinking budgets and will usually choose for the cheapest solution, thereby missing the money that can be used for innovations and reducing the level of vibrations. But it is too simplistic that major manufacturers are reluctant with innovations because the market is facing a crisis.
Ferris occupies a unique position. Ferris zero-turn mowers are equipped with four-wheel independent suspension, similar to car’s and modern agricultural tractors. The suspension system reduces shocks and vibrations caused by the terrain and machine which can cause operator fatigue. Many operator’s slow down to compensate for rough terrain, but when protected from these effects, the operator can increase speed, taking full advantage of the available horsepower which will translate in higher productivity. Ferris mowers equipped with the unique suspension system show a vibration exposure below the maximum standard, which means they are safe to use 8 hours a day without restrictions.
