Back to Petrol Ride On Mowers

The all new Stiga Tornado 9121 W side discharge lawnmower is just one of four similar machines from Stiga. Power is supplied by a Honda GXV630, 688cc V-Twin engine developing 14.3kw of power. equipped with 16" front and 20" rear wheels. This mower does not offer a collection facility, instead it side discharges the cut grass, making it excellent for maintenance of grass which may have become a little longer than a collector can easily cope with, and where the finish is not so critical. With the mulch cover in place the mower will leave an excellent finish on shorter grass too.

For the 2020 season this mower comes with the new Smart Screen digital display dashboard

Hydrostatic drive and a 121 cm deck give this mower an excellent work rate and areas of around 5 acres can easily be tackled.

This model benefits from the Stiga 5 year warranty (domestic users)

Battery charger, towbar and  mulch kit are available as optional equipment

The engine of this machine requires SAE 10w30 oil. The engine will be filled prior to delivery, but subsequent oil changes will require 2.5 litres of oil. We suggest that a first oil change is carried out at roughly 10 hours use, then on an annual basis.

We would also suggest that an annual service is carried out.

The engine is designed to run on standard unleaded fuel, but please be aware that this fuel will go stale very quickly so it is best to use fuel that is less than 60 days old or engine problems can occur.

We recommend the use of ASPEN 4 fuel as it will last indefinitely without going stale, so peak performance and starting is always guaranteed. ASPEN 4 is however more expensive than standard petrol and can be purchased in sealed 5 litre cans from ourselves at the Colaton Raleigh shop.
