Stiga Combi 53 SQ H - Self-propelled Lawn Mower - Honda GCVx 170 Engine - 51 cm Cutting Width

The Stiga Combi 53 SQ H petrol lawn mower is a machine designed for mowing medium to large surfaces, where you need to move forward continuously and maintain a steady working pace. The rear-wheel drive reduces the effort required to push the lawn mower, making it easier to manoeuvre across large or slightly sloping lawns.

This model is suitable for those who carry out frequent lawn maintenance and require a stable machine with multiple discharge options. The steel cutting deck and large-diameter wheels improve ground contact and manoeuvrability.

The Stiga Combi 53 SQ H petrol lawn mower is equipped with a Honda GCVx170 engine, which transmits power to the rotating blade via a direct drive shaft. The Autochoke system automatically adjusts the air-fuel mixture, making starting easier and maintaining a constant engine speed even with thicker grass.

The cutting blade located under the housing, cuts the grass and channels it into the rear grass collector via the airflow generated by the rotation. Alternatively, the clippings can be discharged sideways or at the rear, or shredded using the mulching system and redistributed over the ground.

The main technical specifications of the Stiga Combi 53 SQ H petrol lawn mower are:

• Honda GCVx170 OHV engine: 166 cm³ displacement and 3.30 kW power; ensures stable operation even under prolonged load.
• Rear-wheel drive: automatic drive on the rear wheels, which reduces the effort required to push and maintains a constant speed.
• 51 cm cutting width: covers a wide area with every pass, reducing time spent on medium to large surfaces.
• 4-in-1 cutting system: collection, mulching, side discharge and rear discharge.
• 60-litre grass collector with indicator: large capacity minimises interruptions and alerts you when emptying is required.
• Centralised cutting height adjustment: 22–80 mm range across 6 positions, to adapt the cut to the season and the growth of the lawn.
• Wheels with bearings and different diameters: 200 mm on the front wheel and 280 mm on the rear wheel; they improve manoeuvrability and stability on the ground.

The machine incorporates useful features such as an adjustable and foldable handlebar and a front handle for lifting.

The Honda GCVx 170 engine is a powerful professional engine with a recoil starter.

With a power output of 3.3 kW at 2900 rpm, combined with this lawn mower’s special blade, it optimises cutting efficiency to achieve a perfect cut, while keeping fuel consumption low.

Caution:

The engine is SUPPLIED WITHOUT ENGINE OIL.
Please read the instruction manual carefully before starting it.

Rated Power: 5.5 HP

The more accurate term would be “Commercial Power”, referring to the classic standard for defining motor power officially used until a few years ago by all the leading engine manufacturers.

* This figure is still the most widely used and advertised in the main commercial sales channels, although it is an inflated figure compared to the actual power.

Actual Power: 4.42 HP (2900 rpm)
This corresponds to the real power delivered at the crankshaft. It is the figure stated as official in the manual or in the engine manufacturer’s technical data.

* This figure may vary for the same engine model depending on the rotational speed at which the equipment manufacturer has decided to operate the engine.

The steel housing gives this machine exceptional strength, combined with excellent lightness.

The steel used for the lawn mower’s housing is protected against both corrosion and rust.

These features make the Stiga lawn mower very durable and long-lasting compared to traditional lawn mowers.

The handlebar can be removed to facilitate storage.

Cutting system with grass collector:

The lawn mower is equipped with a spacious 60-litre plastic grass collector, which is very easy to remove and empty.

An actual handle on the top of the grass collector makes it easy to remove and empty it when it is full.

Full bag indicator: allows the operator to see at a glance when the bag has to be emptied.

REAR DISCHARGE SYSTEM:

Allows you to mow the lawn without using the grass collector, depositing the clippings directly at the rear of the lawn mower.

Simply remove the grass collector and the rear discharge system will automatically engage.

MULCHING CUTTING SYSTEM:

for cutting grass without collecting it, shredding it very finely before depositing it on the ground.

Instant conversion:

• remove the grass collector
• insert the supplied mulching plug
• lower the rear deflector to activate the mulching system

WHAT IS MULCHING:
a cutting system that allows the grass clippings to be shredded and then released onto the lawn, pulverised to such a small extent that they appear almost as if they have been collected. This eliminates the problem of disposing of the clippings, reducing effort and drastically cutting down the time taken to mow. The grass decomposes, turning into nutrients for the lawn itself and into water (grass is 80% water), thus ensuring a perfectly balanced biological cycle. However, it is important to remember that, to ensure the system works as efficiently as possible, the lawn should still be watered, and the grass should be mowed at least once a week.

SIDE DISCHARGE SYSTEM:

for cutting grass without collecting it (even grass slightly taller than normal, given the high disposal capacity of the side discharge deflector)

Leaving the mulching plug in place, so that it blocks the rear grass discharge, simply lift the black side cover on the housing and insert the supplied side deflector with a simple movement.

The LAWN MOWER is designed and intended exclusively for mowing grass in gardens (and not on other types of terrain), characterised by smooth level surfaces without stones or other solid objects, and grass maintained as a “lawn” (i.e. no wild or unmaintained grass), which should be cut regularly, ensuring it does not grow beyond 25–30 cm (as most lawn mowers are unable to cut grass taller than this). Also avoid slopes steeper than 15% (≈9°), except for 4x4 models.

For more demanding jobs, involving wild grass or grass taller than specified, or surfaces rougher than a garden, consider the alternative product categories “Petrol rough cut mower” or “Brush cutter”.

Please also note that grass should only be cut when both the lawn and the ground beneath are completely dry. Mow the grass only in dry weather, well away from periods of rain or watering, and preferably in the afternoon when it is not saturated with morning moisture. Wet grass tends to bend under the weight of the cutting blades, reducing cutting efficiency, increasing the risk of clogging in the cutting deck and placing excessive strain on the engine.
