BlackStone GBD-1500 BS - Professional petrol garden shredder - 15.5 HP B&S XR2100 engine

Blackstone GBD-1500 BS overview:

Engine power: 15.5 Hp

BS: Briggs & Stratton stands for the engine brand.

The Blackstone GBD-1500 BS wood chipper is specifically intended for shredding branches and medium-sized diameter logs.

It is ideal for those who need to take care of their greenery and remove and / or grind quickly and efficiently their biodegradable waste from the ground.

Major strengths of this machine:

• Sturdiness, thanks to the system with steel rotor, which ensures a long service life.
• Cutting diameter (it allows easily shredding up to 90 mm diameter branches, while standard shredders featuring the same power can cut branches up to max. 50/60 mm) - However, large-diameter branches with more than 50 mm diameter have to be entered in the hopper slowly.
• Exceptional working capacity, it can carry out intense and demanding operations even when constantly grinding large diameter wood.
• High hourly output, over the standard petrol wood chippers consisting of rotor with blades and hammers.

Limitations: the final size of the wood chips is larger than average due to the lack of centrifugal hammers. The garden shredder is not suitable for grinding leaves or other small green material. These wood chippers are specifically intended for shredding medium and large-sized diameter branches (according to the max. cutting diameter indicated on each model). They are not suitable for small leaves and green material and small diameter branches.

The Blackstone GBD-1500 BS model is equipped with electric safety devices in compliance with the CE standards.

Warning: Like all wood chippers and garden shredders, it is not suited for shredding grass, leaves, pine needles, etc. (it is intended to shred branches, but it can also grind leaves, needles and others)

Garden shredders intended use:
- The wood chipper must grind only green branches and not dried ones (which would limit its shredding capacity and lead to quick deterioration of the blades);
- The branches must be preferably long, smooth and not knobby (otherwise the cutting diameter would be reduced);
- The branch cutting diameter indicated is the maximum, so it is advised not to shred larger branches. In this case, it would be better to purchase a shredder with a larger branch cutting diameter;
- The cutting diameter can vary according to the amounts of wood (e.g: oak, olive, plum and peach are hardwood and can reduce the cutting capacity of the wood chipper);

The Garden Shredder is powered by a powerful Briggs & Stratton XR2100 4-stroke air-cooled engine 420 cc, with overhead valves and aluminium cylinder.

Features:

Nominal power: 15.5 Hp
The correct term would be "Commercial” Power, meaning the standard definition used until a few years ago by all well-known engine manufacturers.

* This technical feature is the one indicated in the main sales channels, even if it is higher than the real power of the engine.
Rated power: 13.5 Hp
It is the real power of the engine. This is the power indicated as official in the engine instructions manual.

* This technical feature may vary from an engine model to another according to the rotation speed provided by the manufacturer.

The engine is PROVIDED WITHOUT OIL.
Please carefully read the instructions manual before starting the unit.

This garden shredder, like all petrol shredders with roller rotor, must be strictly used at max. engine speed; the shredding rotor is large and must reach the max. speed to ensure high results by harnessing its centrifugal force.

WARNING: operating it at less than full speed can lead to several problems and the wood chipper won’t be able to shred large branches ensuring high quality performance.
- Slowdown or engine shut-down during use;
- quick worn of drive belts between motor and rotor;
- damage to the centrifugal clutch which does not fully expand if the engine is not at maximum speed, leading the engine to wear out and irreparably damaging it;

It is the only machine of its category with intermediate 2-belt drive transmission (V-shaped belt type).

This feature gives high sturdiness to the unit, protecting both the engine and all the shredding system from every possible internal hit or kickback.

Higher durability over time compared to the standard system of all the manufacturers of petrol-powered machineries, as the transmission is directly connected to the shredding cutting system.

UNIFIED HOPPER: considerably speeds up shredding operations.

The single hopper avoids the Operator to separate large branches from smaller and green ones (before shredding), while each of them must be entered in their own hopper in standard garden shredders with 2 separate hoppers.

SELF-FEEDING: Once introduced the branches into the hopper, the shredder draws them inside the shredding chamber autonomously.

SAFETY DEVICE: it is possible to use the device placed around the hopper . In case of emergency, slightly push the device with your hand to immediately stop the machine.

The shredder can be checked for maintenance.

2 blades, among the largest and thickest of their category, are mounted on a large spinning steel plate.

The dual blade system also includes a counter-blade placed in the shredding chamber.

This ensures high-quality wood chips with a high hourly output.

The sturdy rotor is entirely made of steel.

Focus on the the counter-blade adjustment: the counter-blade is tilted with respect to the frame and rotor rotation direction for increasing the wood chipper shredding capacity and performance.

All roller shredders like this one allow high performance by entering leafless and cleaned branches (not thick and with too twigs);
they are ideal for quite large branches and not for many thin or green branches featuring many twigs; this is because the roller system is technically unsuitable for grinding small diameters branches, or green material in general, while they really give their best with larger branches.
This is due to their less "centrifugal" power compared to standard disc and blade models, and to the "greater distance between blade and counter-blade", designed for single branches that are already well cleaned but with a large diameter.

Equipped with adjustable discharge chute:

Focus on setting 1

Focus on setting 2,

Focus on setting 3

The discharge chute is very high, about 1.5 m above the ground, and features a deflector with adjustable inclination.

It allows discharging the wood chips directly into a box.

The machine is also equipped with safety button that allows the Operator to immediately stop the machine in case of danger or whenever is needed.

Further to the deflector tilt, it is also possible to adjust the discharge chute: indeed it can rotate and simply adjusted either to right or left by manually loosening or tightening the proper knobs.

The front support stand is very large and provides stability to the machine. This allows distributing the weight over a greater surface area, thus preventing the garden shredder sinking into soft grounds.

The Blackstone BC 1500 BSE garden shredder is equipped with a comfortable grip to facilitate moving operations.

The wood chipper is also provided with large pneumatic wheels 13x5.00 -6 4 that ensure easy transport.

It features a comfortable and practical tow hitch.
