Special MP 84 HD - Lawn Tractor - Hydrostatic Transmission - Collection Bag - Mulching

The Special MP 84 HD petrol lawn tractor is an ideal choice for those who need a powerful and versatile tool to maintain their garden, even of medium to large size. Powered by the STIGA ST 450 432cc petrol engine, this tractor ensures high performance and reliability, making it perfect for lawn areas up to one hectare.

The cutting width of 84 cm allows for quick work even on large areas, while the hydrostatic transmission allows speed adjustment without changing gears, thus facilitating manoeuvrability and efficiency. Additionally, with 7 cutting height positions ranging from 25 mm to 80 mm, the tractor can be adapted to any type of grass, ensuring a uniform and precise finish.

The tractor is equipped with a 240-litre collection bag, which allows for collecting large amounts of cut grass without the need for frequent emptying. The mulching plug is an additional feature that contributes to lawn care, turning grass clippings into a natural fertilizer to be released directly onto the ground.

The ergonomic design and driving comfort are ensured by an adjustable seat and easy, intuitive controls. Moreover, maintenance is made simple thanks to the presence of a double washing connector, which allows for easy cleaning of the cutting deck by simply connecting a water hose.

Main features:

• STIGA ST 450 432cc Engine: Powerful and reliable, ensures optimal performance for areas up to one hectare.

• 84 cm Cutting Width: Large cutting surface that reduces the number of passes.

• Hydrostatic Transmission: Easy speed adjustment without gear changes, for smooth driving.

• 240-litre Collection Bag: Large to reduce the number of emptying, improving work efficiency.

• Mulching Plug Included: Turns grass clippings into natural fertilizer for the lawn.

The Special MP 84 HD petrol lawn tractor is the ideal choice for those looking for a robust and versatile tool, capable of making lawn care simpler and more efficient, while offering high performance and comfort during use.

The Special MP 84 HD tractor offers two different cutting systems:

1- COLLECTION IN THE BAG (standard): the most traditional, the tractor cuts leaving the grass on the lawn. Recommended system for: large extensions for those who do not need to collect for those who do not cut frequently and find themselves having to cut excessively grown grass, for which the collection system or mulching is no longer effective.

Spacious collection bag with a capacity of 240 litres.

The bag is removable in an instant: just lift it upwards to remove it from its "bridge" seat where it is housed

2- MULCHING (standard): a cutting system that shreds the cut grass leaving it on the lawn, pulverizing it to the point that it will almost seem as if it has been collected. This eliminates the problem of its disposal (reducing effort and drastically shortening the time spent cutting) and also, as it decomposes, it will subsequently transform into a nutrient for the lawn itself and into water (grass is made up of 80% water) thus ensuring a perfectly balanced biological cycle. However, it is useful to remember that, to ensure the absolute efficiency of the system, the lawn must still be irrigated, and the grass cut very often. Switching from one system to another is very easy.

Conversion: remove the collection bag and insert the mulching plug into the central tunnel.

Nominal Power: 16 HP
The most correct term would be “Commercial” Power, meaning the classic standard of power definition officially used until a few years ago by all the most well-known engine manufacturers.

* This data is still more widespread and advertised in the main commercial sales channels, although it is an increased data compared to the actual power.

Effective Power: 9.11 HP (at a rotation speed of 2400 rpm)
Corresponds to the real power expressed at the engine shaft. It is the one indicated as official in the manual or in the technical data of the engine manufacturer.

* It is a data that can vary for the same engine model depending on the rotation speed that the equipment manufacturer has decided to have the applied engine deliver.

Detail of the transmission.

Thanks to the new 2-pedal hydrostatic transmission, driving the tractor will be easy and intuitive. Everything can be controlled simply with the right foot resting on the pedal.

The operation is very simple: to move forward just push the pedal with the toe. The tractor will move forward based on the pressure exerted. To engage reverse, just push with the heel on the other end of the pedal.

As soon as the pedal is released, the machine stops and allows for operation in absolute safety.

Robust gears make the transmission difficult to break. The hydrostatic transmission is by nature decidedly more modern and functional (although more expensive) than the traditional manual gear transmission. The latter, whenever the speed needs to be changed, forces the operator to stop, change gear (because all tractors with manual or mechanical transmission require that the gear change takes place from a standstill), release the clutch and restart at the desired speed. Certainly, if the speed needs to be changed several times (for example in all those gardens where there are trees, pots, or any other kind of obstacle), the traditional gear transmission would be decidedly impractical. The hydrostatic transmission instead allows for immediate speed changes, without ever stopping, in the most absolute practicality, in a totally automatic way, simply by varying the pressure on the pedal of this transmission.

the lawn tractor Special MP 84 HD is equipped with a 2-blade cutting deck.

The tractor is equipped as standard with collection blades.

Cutting deck width of 84 cm.

The deck of the lawn tractor is floating: it easily adapts to the undulations of the ground (as long as they are not excessively harsh). Moreover, this model is equipped with a wide protection that completely surrounds the deck.

The blade engagement is electromagnetic and is controlled through the yellow button to the right of the steering wheel. This system avoids manual engagement through the classic lever found on many types of tractors, and works thanks to an electromagnetic clutch that allows for easy and quick blade engagement

The available cutting positions are 7 and are adjustable via a lever. They can be varied from a minimum of 25 mm to a maximum of 80 mm.

The cutting deck is equipped with 2 anti-scalp wheels and double washing connector, both for the right side of the deck and for the left side.

The controls and adjustments of the lawn tractor Special MP 84 HD are easy and intuitive:

• Blade rotation speed regulator
• Parking brake
• Ignition block with key
• Foot brake
• Button for reverse cutting
• Cutting height adjustment lever
• Hydrostatic pedal transmission for forward and reverse
• Electromagnetic blade engagement with yellow button to the right of the steering wheel

The ride-on lawn mower is designed and intended exclusively for cutting grass in gardens and parks (and not on other types of terrain). The working surface must be level, free of irregularities, stones, or other solid objects, and covered with maintained lawn grass (not uncultivated or spontaneous vegetation). Grass should be cut regularly and must not be allowed to grow beyond 25–30 cm, as most ride-on mowers are no longer capable of cutting at this height. Slopes exceeding 15% (equivalent to 9°) must be avoided, except when using 4x4 models.

For heavier-duty tasks, involving spontaneous vegetation, grass taller than the above-mentioned limits, or rougher surfaces than a garden, please consider alternative product categories such as Petrol Flail Mowers or Ride-On Flail Lawn, which are suitable for tall and uncultivated grass.

Grass must only be cut when both the lawn and the underlying soil are completely dry. Mowing operations should be carried out exclusively in dry weather, well away from periods of rain or irrigation, and preferably in the afternoon, when the grass is no longer affected by morning humidity. Wet grass tends to bend under the blades, reducing cutting efficiency, increasing the risk of clogging inside the deck, and subjecting both the engine and the transmission belt to excessive strain, which may result in damage.
