Grillo's Rotary Tiller Design
Grillo rotary tillers are simple, easy to handle, sturdy, safe and... above all, reliable!
Grillo rotary tillers 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 rotary tillerswork at depth and on large clods. They minimise under-soil compacting.
Grillo rotary tillersare well balanced and can even be used on soft ground without sinking. They move forward smoothly, without undue effort from the operator.
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.
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.
