The STIGA Tornado 6121 HW is a high-performance garden tractor designed to handle the tallest grass and the most challenging terrain! A perfectly balanced STIGA ST 650 twin-cylinder engine works to optimize torque-output and lessens fatiguing vibration, and providing effective protection against the ingress of damaging airborne debris. The Tornado 6121 HW is supplied with a highly productive 121cm-wide cutter-deck that can be height-adjusted through seven stages to suit the conditions; and which is fitted with a series of six anti-scalp wheels that prevent turf damage when executing turns on slopes and undulating ground. It features a pedal-controlled hydrostatic transmission, so you’ll enjoy smooth acceleration and deceleration with no need to shift gear manually; and it benefits from a six-LED display that provides a comprehensive overview of all important operating parameters. Thanks to its robust cast-iron front axle, the Tornado 6121 HW is well equipped to cope with regular heavy-duty use over rough ground. LED headlights provide essential illumination should you need to work on into the evening; while a hosepipe attachment point makes the job of clearing performance-limiting debris from the underside of the deck quick and easy. The Tornado 6121 HW offers excellent user-comfort, with its lever-adjusted seat, soft-grip steering-wheel all contributing to driving-pleasure.

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.
