Gardeners looking for a fast and efficient way to manage large areas of overgrown grass should take a look at the well-equipped Alpina AT3 98 A!
Its ability to handle out-of-control growth is thanks to its side-discharge cutter-deck - long grass-cuttings that would be impractical to collect are instead ejected in neat and tidy rows to the right-hand side of the tractor, thus avoiding chute-blockages and saving time by eliminating the need for emptying-stops.
The AT3 98 A has been fitted with an Alpina ST350 engine; a highly efficient four-stroke power-pack that’s capable of producing a muscular 6.5kW from a compact 352cc cylinder-capacity; and which benefits from Alpina’s noise-minimizing and emission-cutting OHV (overhead-valve) technology.
It’s equipped with large-diameter drive-wheels that provide essential traction when you’re working on inclines or damp ground; and it benefits from electromagnetic PTO engagement, so you’ll find it quick and easy to start and stop the blades.
Adaptable and flexible in use, the AT3 98 A offers seven preset heights-of-cut and combines an optional mulch-capability with a multi-speed manual drive.
Other important features include anti-scalp deck-wheels for turf-protection when maneuvering on hills and uneven ground; and an Alpina Smart seat with lower-back support for long hours of fatigue-free mowing.

FAQ 1 questionWhat is the proper way to clean the lawn tractor after mowing the grass?
FAQ 1 answerThe 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.
FAQ 2 questionWhat action should be carried out before winter storage or before storing it for a period longer than 30 days?
FAQ 2 answerAfter 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.
FAQ 3 questionWhat 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?
FAQ 3 answerRefuel 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.
FAQ 4 questionWhat standard maintenance operations does the lawn mower tractor need?
FAQ 4 answerBefore 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.
FAQ 5 questionWhat are the cutting functions of the lawn tractor?
FAQ 5 answerThe 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.
FAQ 6 questionWhat kinds of parts and accessories can the lawn tractor be equipped with?
FAQ 6 answerThe 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.
