The Maximo Professional with low-frequency suspension is suited for medium and heavy-duty tractors. This vibration-optimized air suspension is perfectly suited for use in heavy vehicles and tractors with axle and cabin suspensions. Because these vehicles have a low natural frequency, Grammer developed a low-frequency suspension. The benefits: the low-frequency suspension absorbs vertical vibrations and jolts to prevent a resonant build-up that could otherwise lead to critical states. This meets a decisive criterion; the lower the seat suspension’s natural frequency, the greater the suspension comfort for the driver.
