Description
Supplied with a 98cm side-discharge cutter-deck, the Alpina AT3 98 HA is a fast and efficient performer over large areas and will take the sort of overgrown grass found in meadows and outlying informal stretches in its stride!
Under the new, design-optimized bonnet is an STIGA ST 400 engine; a 414cc motor that produces an impressive 7.1kW of clean, low-emission power; and which will prove economical and quiet-running.
The foot-pedal operated hydrostatic transmission on the AT3 98 HA confers fantastic maneuverability - you’ll be able to adjust the ground-speed in infinite increments, smoothly slowing down when approaching obstacles, and then accelerating intuitively into long, unbroken passes.
A robust bumper provides reassurance when it comes to front-end impact protection; while a convenient electromagnetic PTO clutch means the blades are activated by simply pushing a button.
The AT3 98 HA benefits from substantial 457mm drive-wheels that ensure non-slip traction on sloping ground and in damp, muddy conditions.
It’s fitted with twin-headlights for safe low-light mowing; and it offers seven preset cutting-heights that will help you to create the sort of finish you prefer. Thanks to its included mulching capability, the AT3 98 HA is also suitable for use on frequently-mown formal lawns.

Faqs
What is the proper way to clean the lawn tractor after mowing the grass?
The exterior of the tractor mower must be cleaned with water and detergent, paying attention not to get water in the electrical system, motor and circuit board located under the instrument panel. The collection bag should be emptied and cleaned of residue, then remounted so the cutting assembly can be washed, and then removed, rinsed and allowed to dry. When washing the cutting device assembly and the expulsion chute, the collection bag or rear discharge shield must be fitted, the operator must be seated, the cutting device assembly must be in position “1”, the engine running, transmission placed in neutral and the cutting device must be connected. Then connect a water hose to the appropriate pipe fittings and allow the water to flow for a few minutes while keeping the cutting devices in motion.
What action should be carried out before winter storage or before storing it for a period longer than 30 days?
After allowing the engine to cool down and fully recharging the battery, disconnect the battery cables and store it in a cool and dry place. Empty the fuel tank, clean the machine thoroughly, check the condition of the cutting device assembly, and, if necessary, contact the service centre. Then store the lawn tractor with the cutting deck in a lowered position, in a sheltered environment and, if possible, covered with a sheet.
What action should be carried out before initially using a riding tractor that has been stored over a winter or for a period longer than 30 days?
Refuel it and check the oil level, air filter and petrol filter. Check that the tyres are correctly pressurised and then set up the lawn mower tractor according to how you intend to carry out the mowing (side discharge, collection, rear discharge, mulching). For further information about the preliminary operations and safety checks, please refer to the designated sections of the instructions manual.
What standard maintenance operations does the lawn mower tractor need?
Before each use, we recommend that you perform safety and control checks, check the tyre pressure, and replenish the fuel and oil tank, if necessary. After each use, arrange for a general cleaning of the riding tractor. Please refer to the designated section of the instruction manual (“maintenance table”) for the regular actions recommended to ensure optimal use of the machine.
What are the cutting functions of the lawn tractor?
The riding tractor can be set up in different cutting modes: rear bag collection or rear discharge, or mowing and chopping the grass using the special “mulching kit” function. The mulching cutting system allows you to mow the grass into fine particles, which remain on the lawn, restore nutrients and support growth.
What kinds of parts and accessories can the lawn tractor be equipped with?
The lawn tractor can be equipped with various parts and accessories to increase its functions and ensure maximum versatility all year round. For the complete list of parts and accessories, please refer to the relevant product page on the website.
