GeoTech GSB50 - Petrol garden shredder - Gasoline engine 6 HP

Garden shredders allow reducing weeds and twigs in an easy to handle and suitable size for composting. Shredding operations also allow reducing the material decomposing time.

The wood chipper shreds and compacts wood in a very small space and the shredded material can be used to produce humus (compost) to keep your soil and plants healthy and reach in nutrients.

The GeoTech GSB50 garden shredder features a max. 45 mm cutting diameter.

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);

Features:

• Engine type: 4-Stroke, single cylinder - OHV
• Cylinder type: aluminium
• Cubic capacity: 173 cm³
• Power: 6 Hp
• Starting: recoil start

Engine with belt drive.

Oil tank: 0.55 L

Petrol tank: 1.2 L

This gives the machine extraordinary sturdiness, protecting both the engine and the internal shredding unit from any kind of internal shock or kickback.

Nominal power: 6 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: 4.3 Hp
It refers to the real power of the engine. This is the power indicated as official in the engine instructions manual.

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

Shredder equipped with a single hopper.

The hopper is equipped with 2 openings for entering branches. One more specific for large branches (thus wide enough to allow the Operator using the pusher) and the other one more specific for small branches or green material (again using the pusher provided).

Focus on the dual opening.

The garden shredder is equipped with a pusher to help the Operator pushing in the material to be shredded.

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

Large and highly-thick 2 shredding blades are mounted on a steel rotating roller.

The rotor is sturdy and entirely made of steel.

The 2 blades are reversible. Once completely worn on one side, instead of replacing them, the blades can be turned to the opposite side where they will have a new and sharp blade.

Focus on the wood chips. As you can see, the 2% of the shredded material ends up outside the collector. This is because the collector does not completely cover the space of the wood chips.

The garden shredder body is made of steel. It is well impact-resistant to shocks or kickbacks.

The wood chipper is also equipped with large 20 cm pneumatic wheels that allow easy transport.

Focus on the engine On/Off switch.

Focus on the safety device under the garden shredder. The machine does not start if the Operator has not correctly entered the collector. Focus on the safety key to lock the collector.

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

WARNING: always check that you have entered the collector correctly. Otherwise, the machine won’t start.

Recommendations for use

To ensure the maximum efficiency and durability of the wood chipper,  the instructions below must be strictly followed. Failure to do so constitutes improper use and carries a serious risk of damage to the product (such damage is not covered by the warranty).

• DO NOT use the wood chipper to shred:

1. Pine needles
2. Grass or piles of leaves
3. Wet garden waste
4. Whole pallets or parts thereof
5. Construction waste
6. Wood and/or roots covered in soil or stones.

These materials, which lack a woody texture, tend to form a paste that blocks the shredding chamber and the discharge chute, overloading the engine. However, branches with leaves may be fed into the machine, provided they are preferably straight in shape.

• DO NOT feed in pallets or construction waste: ensure that the material contains no nails, screws, iron wire or concrete debris. Impact with foreign objects will irreparably damage the cutting rotor and may result in the violent ejection of metal fragments.
• DO NOT shred wood and/or roots covered in soil: the abrasive action of soil and sand on the cutting blades at high speed causes immediate wear. The cutting blade loses its sharpness within minutes, making extraordinary maintenance necessary. Furthermore, the likely presence of stones, even small ones, would inevitably damage the wood chipper.
• Pay attention to wood freshness: the specified maximum cutting diameter refers to ‘green’ wood, i.e. fresh branches recently cut from the tree (which is the ideal time to process them in the wood chipper) and of medium consistency. For very hard types of wood (e.g. oak, olive, plum, peach), the wood chipper’s actual cutting capacity may decrease proportionally to the hardness of the wood. Furthermore, the declared maximum cutting diameter should be considered as an exception  during use and not the standard operating conditions, as it would mean operating the wood chipper continuously at the limits of its capabilities.
• DO NOT shred dry or seasoned wood (e.g. old posts, beams, sticks): the wood chipper is designed to process freshly cut branches. Dry wood is significantly harder than fresh wood and can damage the cutting blades by creating nicks or causing them to lose their sharpness quickly, as well as placing severe strain on the transmission mechanism. 
• DO NOT feed material in when the engine is off or running at low revs: start the wood chipper and always bring it up to full speed before feeding in the material. Similarly, never switch off the engine while there is still material inside the cutting chamber.
• DO NOT FORCE THE FEED: the wood chipper must pull the material in automatically (self-feeding). If the branch does not advance, the blades may be worn or the branch may be too knotty. Forcing material into the hopper could cause the cutting rotor to jam and result in serious damage to the transmission.
• DO NOT operate the wood chipper with worn or damaged blades: under these conditions, shredding occurs by ‘impact’ rather than by ‘cutting’. The resulting strong vibrations and stresses can cause serious structural damage to all components of the wood chipper.
• Fuel storage:

1. Use approved tanks
2. Check that metal tanks are clean and free from corrosion
3. Store fuel in a cool, dry place away from direct sunlight
4. Use the petrol within 30–60 days
5. If necessary, use a stabiliser to extend its shelf life

If the machine is to be left unused for a prolonged period, empty the fuel tank or use fuel containing a stabiliser additive.
