BlackStone GBK-700 L - Professional petrol garden shredder - 7.0 HP Loncin engine

Blackstone GBK-700 L overview:

The Blackstone GBK-700 L is a silent and highly-powerful garden shredder. It allows converting all pruning and vegetable waste into compost for your green area.

Engine power: 7 Hp

It is very easy to move, as it is equipped with large, durable wheels.

The garden shredder is not suitable for grinding leaves or other small green material.

The Balckstone GBK-700 L model is equipped with electric safety devices in compliance with the CE standards.

Major strengths of this machine:

• Sturdiness, thanks to the system with steel rotor which ensures a long service life.
• Cutting diameter: it can cut branches of up to 65 mm diameter. Its shredding capacity is higher than standard.
• 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.

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 equipped with a powerful Loncin G210FA engine with overhead valves and aluminium cylinder.

Features:

Nominal power: 9 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: 7 Hp (at 2500 rpm)
It refers to the real power of the engine. This is the power indicated as official in the engine instructions manual.

* This technical feature may vary from a 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 up 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 rotor is sturdy and entirely made of steel.

This dual-blade system is also equipped with a counter-blade to optimise shredding results.

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

All shredders equipped with roller system ensures best performance by entering branches already trimmed and cleaned branches (not thick and with excessive branching);

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.

The discharge chute is very high, about 1 m above the ground, and features a deflector with adjustable inclination.

It allows discharging the wood chips directly into a box.

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 GBK-700 L shredder is equipped with dual grip to facilitate the moving operations.

The wood chipper is also provided with large wheels that ensure easy transport.
