The wide range of Grillo motor-hoes has the right answer for all farm and garden jobs, for hobbyist or professional use. Grillo motor-hoes are simple, easy to handle, sturdy, safe and... above all, reliable!

THE ADVANTAGES OF WORKING WITH A GRILLO MOTOR-HOE

• Grillo motor-hoes are simple and reliable. Designed and built to last over time.
• Grillo motor-hoes are even able to work in a greenhouse or on a small vegetable plot, and can hoe even in corners without too many awkward manoeuvres. Vertical shaft motor-hoes are the best for this type of job.
• Grillo motor-hoes are even able to work with stones or very hard ground (Mod. 11500 -12000).
• Grillo motor-hoes work at depth and on large clods. They minimise under-soil compacting.
• Grillo motor-hoes are well balanced and can even be used on soft ground without sinking. They move forward smoothly, without undue effort from the operator.
• Grillo motor-hoes have excellent balance even when working on slopes (especially the 11500 Diesel).
• Grillo motor-hoes have the right power for the job in hand.
• Grillo motor-hoes (2500 - 3500 - 11500 - 12000) can be fitted with the scrub cleaner rolls used for finishing on soft ground to eliminate weeds.

A few hints for the best results

Adjusting the working depth
*The working depth depends on the amount of pressure the operator applies on the spur and on the height at which this component is set. With the spur set high, the machine's centre of gravity is shifted forward, so it tends to travel more quickly and not go deep. With the spur set low, the machine will tend to work "on the spot" and to dig in.

The side discs
*The side discs are important; they help to keep the machine going straight provide a clear edge to the tilled zone, stop soil being flung out to cover vegetable crops and also prevent damage to the roots of plants. On very soft ground, they ensure the machine floats well and travels forward smoothly, without digging in. On very hard ground, it is better to work without discs to allow the tines to get deep down; the same applies on wet ground which tends to clog up the hoe.

Tilling hard ground
*When working on very hard ground, it is best to keep the spur turned to face forward to allow the operator to manoeuvre the machine without too much effort. Perform a first pass to break up the surface crust, then pass again to till in depth.

Tilling uphill
For good uphill tilling, the ideal motor-hoe should have front-mounted engine, or front ballast, since the weight distribution means that this gives the optimal load on the hoe for smooth, even travel. The spur is also crucial for good tilling results; it must be adjusted to suit the consistency of the ground. For example, on loose ground the spur should be kept high. The side discs should not be removed because they help forward travel, like the various components that extend the width of the hoe, which also improve the machine's stability. On very steep downhill slopes, the spur should be turned forward to keep the machine firmly on the ground.

Accessories
After the hoeing implement itself, the furrower is the accessory most widely used on the motor-hoe. It is fitted instead of the spur and is used in combination with the hoe itself. It creates trenches of adjustable width and depth for sowing, irrigation or drainage. The hoe's propulsive action allows even small-sized machines to form deep trenches.

Tine
The tine flanges of GRILLO 2500-3500-11500-12000 motor-hoes have two holes so that the tines can be fitted at 90° or in a spiral formation. The tines should be fitted at 90° for hard, stony ground or wet, clay soils that tend to clog up the hoe. The tines hit the ground harder, breaking up the surface crust more effectively. The tines should be fitted in a spiral on soft ground, since the float is enhanced and the machine travels more smoothly.

Ploughing
Ploughs can be fitted on the PRINCE55 III - 2500- 3500 - 11500 - 12000 models and there is a choice of two types: single furrow and reversible, ideal when ploughing in both directions. The machine has to be equipped with adjustable wheels and weights, with the plough fitted instead of the spur. If the plough is properly adjusted, excellent results will be obtained without excessive operator effort. The depth obtainable may vary from 10 to 20 cm depending on the ground. During work, the coulter must always be perfectly vertical, while the heel of the plough must just touch the bottom of the furrow. This will put less strain on the engine and turn the ground evenly.

Inverted clutch (GRILLO patent)
The inverted clutch guarantees greater convenience and safe operation. It stops the machine immediately if the operator accidentally lets go of the handlebar. However, the engine does not cut out if the operator wishes to stop work for a moment. The inverted clutch is a device installed as standard on GRILLO 2500 -3500 -11500 - 12000 models
