Professional lawn mower with perfect grass collection

A professional among lawn mowers. The AS 531 4T MK is equipped with many extras and ideally suited for the care and maintenance of demanding green areas such as steep terrain and confined spaces. A mulch kit can be mounted and dismounted without tools, a feature that now comes as standard equipment. Thus, the AS 531 4T MK functions as a mulching mower or as a lawn mower, with or without a collection bag— 3in1. A Honda GSV 190 ccm engine offers up to 3.8 kW (5.2 hp), making the AS 531 4T MK an ideal choice for professional operators. The grass collection bag has 75 litres of capacity and a fill level indicator, with the bar arranged in the middle so it can be easily emptied. The AS 531 4T MK is the only machine in its class with a safety brake and limited slip differential. As soon as the blade clutch lever is released the parking brake activates and the mower comes to a standstill, regardless of how steep the slope. This function maximizes user safety. The mower is easily operated with an open V-shape handlebar developed by AS-Motor: the left hand regulates speed from 3.0–4.5 km/h while the machine is in motion. The right hand steers and activates the blade clutch, the traction drive, and the parking brake. The blade clutch makes it possible to bring the blade to a standstill without switching off and restarting the engine, for example, when emptying the collection bag. A pivoting handlebar allows the AS 531 4T MK to be used comfortably along house walls and shrubbery or when mowing next to parked cars. The handlebar has rubber-bearing support and VibrationProtect vibration damping that reduces hand-arm vibration to a minimum. In addition, optimal weight distribution ensures ergonomic handling and fatigue-free work.
