AT4 98 HA

A 98cm garden tractor with a 452cc STIGA engine and a hydrostatic drive. Can either mulch clippings or collect them in a 200-litre catcher.
  • check A 2-in-1 machine – choose between bagging and mulching modes
  • check Top-quality STIGA OHV engine
  • check Sizeable 98cm cutting-width
  • check Foot-pedal hydrostatic transmission for intuitive ground-speed adjustment
  • check Comfortable, ergonomically optimised seat and steering-wheel
Large enough to cover a substantial area fast, but compact enough to be easy to manage, the Alpina AT4 98 HA is ideal for gardeners looking to take their first steps into the world of petrol garden tractors!
Supplying an impressive 7.9kw (10.6hp) to the blades and rear wheels is a 452cc STIGA ST500 engine with OHV technology for low-emission operation and excellent fuel-economy; and an electric key ignition-system for rapid, reliable starting every single time.
The highly manoeuvrable AT4 98 HA benefits from a foot-pedal-controlled hydrostatic transmission; a premium feature that gives the driver smooth, car-like ground-speed control with no need to stop and manually change gear.
Both collection- and mulch-capable, and offering seven pre-set cutting-height positions, the AT4 98 HA is an adaptable machine that can be set-up to perform effectively on a wide variety of grass-types (mulch-kit optional).
Powerful headlights will enable you to keep going well into the evening, if necessary; while electromagnetic PTO engagement means you can start and stop the blades at the simple push of a button.
A delight to drive, the AT4 98 HA has an LED dashboard display and combines an Alpina Ergonomic steering wheel with an Alpina Smart low-back seat.
Also featured is an audible warning alarm that alerts you when the 200-litre collector has reached capacity.
This 98cm model is a good match for areas up to 4000m2.
