Nominal Power: 4.5 HP
The more correct term would be “Commercial” Power, meaning the classic standard of power definition officially used until a few years ago by all the most renowned engine manufacturers.* This data is still more widespread and advertised in the main commercial sales channels, although it is an exaggerated figure compared to the actual power.

Effective Power: 3.7 HP @ 2900rpm
Corresponds to the real power expressed at the crankshaft. It is the one indicated as official in the engine manufacturer's manual or technical data.* This data can vary for the same engine model depending on the rotation speed that the equipment manufacturer has decided to have the engine deliver.

Useful blade cutting width 51 cm.

The mounted blade is made of tempered steel of a universal type, suitable for performing the 4 functions provided by the lawn mower.

The blade is of high thickness, designed to perform the four cutting functions provided by the machine: mulching, rear discharge, side discharge, and collection in the bag.

Practical front grass comb that lifts the grass just before cutting to ensure clean and uniform results.

The steel chassis gives this machine high robustness, combined with excellent lightness.

Rear-wheel drive (self-propulsion).

Forward speed: 3.7 Km/h.

Equipped with a robust gear transmission.

Allows the operator to conduct the grass cutting operation without effort, optimising the machine's traction and advancement efficiency.

The high-wheel system provides incredible manoeuvrability. The wheels are mounted on ball bearings that significantly extend their lifespan.

The Alpina lawn mower has 6 cutting height adjustments available, thanks to a centralised lever on the wheels, making it extremely easy to adapt the cut to the grass conditions.

They vary from a minimum of 22mm to a maximum of 80mm.

The centralised adjustment is incredibly fast and intuitive.

BAG COLLECTION CUTTING SYSTEM

Spacious 60-litre collection bag with full basket indicator .

The lower part is made of plastic. Its flexibility allows for easy emptying of the basket when full.

Practical handle located on the top of the basket to facilitate its removal.

REAR DISCHARGE SYSTEM

Allows cutting the grass without using the collection bag, depositing it directly at the back of the lawn mower.

Simply remove the collection basket, and the rear discharge system will automatically function.

SIDE DISCHARGE SYSTEM:

for cutting grass without collection (even slightly taller grass, given the high disposal capacity of the side discharge deflector)

Leaving the mulching plug inserted, so that it blocks the grass discharge at the rear, simply lift the black side cover on the chassis and insert with a

simple gesture the side deflector provided.

MULCHING CUTTING SYSTEM:

For cutting grass without collection, finely pulverising it before depositing it on the ground.

Immediate conversion: simply remove the collection basket, insert the mulching plug provided, and lower the rear deflector to enable the mulching system.

WHAT IS MULCHING:
a cutting system that allows the cut grass to be shredded and then released onto the lawn, pulverised to the point that it almost appears to have 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 later turn 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 watered, and the grass cut at least once a week.

Controls located on the handlebar are simple and intuitive.

The handlebar is removable to facilitate storage operations.

Engine brake lever: it is the lever that allows the engine to start and stop and simultaneously engages/disengages the cutting device.

Drive engagement lever: it is the lever that engages the wheel drive and allows the machine to move forward
