With the Alpina AT4 84 HA Lawn Tractor, you’ll get powerful performance, excellent versatility and superior driving-comfort, all at an affordable price! Delivering that powerful performance is a 452cc Alpina ST500 single-cylinder four-stroke motor that’s rated at a substantial 7.4kW; and which will prove quiet, clean, smooth and economical in operation, thanks to Alpina’s overhead-valve technology. The AT4 84 HA has a foot-pedal-controlled hydrostatic drive; a desirable feature that enables you to control the ground-speed much like you would with an automatic-transmission car - the more pressure you apply to the pedal, the faster you’ll go! A front-mounted bumper works to prevent engine-damage in the event of accidental impact; while an electromagnetic power-take-off clutch makes starting and stopping the blades an effort-free process. Offering three mowing-modes - bagging; rear-discharge; mulching - and seven preset cutting-heights, the flexible AT4 84 HA can be configured to produce fantastic results, no matter what grass-conditions you’re faced with. It’s equipped with bright but energy-efficient LED headlights, so it can be safely driven when the ambient light’s poor; and it benefits from a series of gauge-wheels that ensure the edges and corners of the deck won’t mark the turf when you’re executing turns on uneven ground. This model has a relatively compact 84cm working-width and comes with a largest-in-class 240-litre collector.
