Climb aboard the unstoppable Stiga Tornado Pro 9121 XWSY Lawn Tractor and you’ll be able to manage the toughest mowing and towing jobs on the most challenging terrain! Its 121 cm cutter-deck has been equipped with three robust metal blades, that will power their way through dense, overgrown grass with supreme ease. Once cut, the grass is blown at speed through the side-discharge chute and is laid out in neat rows. The careful attention paid to the design of the chute ensures tall, damp grass won’t cause blockages. In addition to side discharge, the Tornado Pro can also perform mulching cut, thanks to the included plug. The STIGA Tornado Pro 9121 XWSY features a smart 5.5" widescreen colour display that provides clear, easy-read information on key operating parameters, such as hours worked and service requirements. STIGA Best Cutting-Zone function will always let the operator know when they're achieving the best cutting-performance, thanks to green-light indicator, whatever the terrain and grass-type. At the heart of the Tornado Pro is a Honda GCV690 engine; a 688cc air-cooled twin-cylinder unit with a V-Twin configuration that works to maximise output, while minimising uncomfortable vibration. Designed with durability in mind, the engine incorporates a steel crankshaft, a two-stage air-filter and a rev-limiter. Fitted with an adjustable Comfort Plus seat with armrests and combining a soft-grip steering wheel with a cruise control function and a 12 V phone recharge socket, the Tornado Pro excels in terms of both comfort and convenience.

FAQ 1 question What is the proper way to clean the machine after mowing the grass?
FAQ 1 answer The exterior of the machine must be cleaned with water and neutral detergent, paying attention not to get water in the electrical system, motor and circuit board located under the instrument panel. When washing the cutting device assembly and the expulsion chute, the side discharge deflector 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 question What action should be carried out before winter storage or before storing it for a period longer than 30 days?
FAQ 2 answer 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 machine with the cutting deck in a lowered position, in a sheltered environment and, if possible, covered with a sheet.
FAQ 3 question What action should be carried out before initially using a machine that has been stored over a winter or for a period longer than 30 days?
FAQ 3 answer Refuel it and check the oil level, air filter and petrol filter. Check that the tyres are correctly pressurised and then set up the machine 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 question What standard maintenance operations does the machine need?
FAQ 4 answer 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 machine. 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 question What are the cutting functions of the machine?
FAQ 5 answer The machine can be set up in different cutting modes: side discharge or cutting 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 question What kinds of parts and accessories can the tractor be equipped with?
FAQ 6 answer The machine 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.
