Walk behind Tractor Features:

The Walk behind Tractor was Grillo's original product when they started manufacturing in 1950.   Sixty years of testing and use has seen this original model grow into a range of modern, versatile and powerful two wheel tractors that provide solutions to people in a variety of applications from small lifestyle blocks and farms to market gardens. 

Ultimate Versatility

With a range of attachments from traditional rotary tillers and furrowers and rotating ploughs to sickle bars, snow-throwers, rotary sweepers, flail mowers, grass cutters and dumping towed trailers  the Two Wheel Tractor is one of the most versatile machines you can have on a property.
Reducing the number of machines on your property while increasing the application of activities you can perform brings a better return on the investment, saves space and machine storage and above all, only one machine has to be serviced and kept in good working order.

They are gearbox driven only.  No belts or chains!

All Grillo Two Wheel Tractors have been designed with transmissions using precision gears and hardened steel shafts mounted on ball bearings. This type of transmission can draw on more than forty years' experience which is the best guarantee of reliability, designed to offer years of trouble free operation.

Adjustable,ergonomic handlebars

Grillo Two Wheel Tractors have been designed with adjustable, ergonomic handlebars.  Different models use various kinds of handlebar adjustment depending on their application. (Models designed to take both tilling and mowing attachments have reversible handles).  The quick adjustment device gives more effective leverage at the end of the row, during transport or during servicing.

Revolving handlebars pivot 180°. to allow multiple types of attachments to be fitted and used.  Mowing attachments are fitted out the front of the machine with engine at the rear, by rotating the handlebars, the tilling attachment can be fitted behind the unit with engine at front (this provides balance).  Height and width adjustment allow the operator to drive the machine from the right or left when tilling, mowing a lawn or using the snow-thrower. For this reason, the brake and clutch wires Grillo uses are twice the usual size.

Well Balanced

Because the engine is in line with the transmission, all Grillo Two Wheel Tractors achieve  a low centre of gravity . On other machines (e.g. those with belt drives) the engine is higher up, making them less stable.

All Grillo walking tractors are designed so that the machine's weight is over the tiller. This means the operator does not have to press down on the handlebar so hard to keep the tiller in the ground.

Quicker Tiller Rotation. Grillo tiller tines turn 20 times for each revolution of the wheel. This allows the tines to chop the soil and vegetation into small pieces, producing an ideal growth medium for plants.

Perfect Tilling

Grillo tillers break up the soil even underneath the transmission unit thanks to the adjustable depth stake.

Cheaper tillers leave an untilled strip 5-8 cm wide. What's more, the adjustable width steel tiller casing, has specially shaped side guards which do not act as a brake on the machine's progress (fully compliant with EC standards.) This retains the soil inside the tiller without clogging, tilling it more finely.

The 6 Tine Group Tiller

The 6-tine group tiller, exclusive to Grillo, is also available in a choice of models. It tills the ground much more finely and provides excellent results on very hard and medium consistency soils (not recommended on wet clay soils).
The depth stake "foot" is easily adjustable from the outside for trouble free adjusting -  even when at work, giving exactly the right setting for uniform tilling.  This eliminates effort and the need to wrestle with spanners.

Sickle Bar (Cutter Bar)

Grillo sickle bars are ideal for cutting all grass types and can be used in rustic areas, fruit orchards and can provide grass for animal feed. The crank mechanism is built using premium steel types and is fitted with grease nipples on all articulating parts. The floating grass disperser is mounted on anti-vibration rubbers with a special profile to dispel the grass in the most demanding conditions; the grass is cut, dropped to the ground by the action of the wheels allowing easier control when moving forwards. Blade sections are made of special steel and fixed with special 6 mm length rivets. The cutter bar’s teeth are made of a special profile to ensure a perfect cut and are made of special heat treated steel. The blade tensioners are adjustable ensuring so a constant fit between blade and teeth.

Independent PTO and Wheel Drive

All Grillo Two Wheel Tractors have PTO engagement that is independent of the wheel drive. This allows the operator to disengage the PTO while the wheels are in motion, for safer transport.

Reverse Gear PTO Cut Out

Grillo Two Wheel Tractors are fitted with a mechanical device which automatically cuts out the PTO when the machine switches to reverse gear. The operator cannot engage reverse gear while the tiller tines are moving. This provides the operator with maximum safety protection.  

Differential Lock

The Grillo G107d and the Grillo G110 are fitted with differential lock - (easily locked when not required, such as for tilling), for increasing traction by engaging both driving wheels, and optional independent brakes for easier turning and manoeuvring.


Grillo Two Wheel tractors are fitted with a professional class standard or inverted cone clutch produced in-house by Grillo: it wastes no power and extends the working life of the gearbox. There are also protective features on some accessories.

Quality Engines

The engines installed on Grillo Two Wheel Tractors are all quality units that above all - give the right results for the intended type of use - they are all selected and tested in advance to perform to Grillo quality standards.

Attachment examples:

Berta Rotary Plough

The Berta Company of Italy has made the rotary plough applicable as a rear-PTO implement for all European walk-behind tractors.
Essentially the rotary plough has a vertical shaft with 4 spiral blades (ploughshares) turning at approximately 300 rpm.  Soil in front of the plough is cut into and then immediately centrifugally discharged to the side as it is inverted.  Basically, in a single pass through sod, the plough will leave 10-12 inches of worked soil.  And because the soil is not trapped under a hood and repeatedly pulverized (like with a tiller), the soil structure is not beaten to death.
Tilth of soil is similar to that which has been ploughed and disked with a conventional tractor:  good enough for large seeds and vegetable starts; may need secondary tillage on the top 2-3” for small seeds.  A Plough works 8-10” wide per pass, but unlike a tiller, there is no such thing as a ‘second pass’ with a RotaryPlough, so it more than makes up for it’s narrow working width in the fact that it only has to go over the ground once.  The horizontal movement of the blades through the soil causes little or no hardpan and is actually less violent than a tiller when hitting rocks, tree roots, etc. 

Absolutely unbeatable for breaking new ground and excellent for turning in standing cover crop up to 4 feet tall.  (A shear blade at the top of the rotor keeps material from “winding” around the shaft).  Exploiting the side discharge nature of this tool (which will throw soil up to 24 inches past the edge of the hood and flat-topped raised beds, power ridging and hilling can be achieved.  It makes a good trencher, too.  Depth can be regulated by a gauge wheel (included) and discharge can be controlled by a removable side flap (included) and by adjusting the top cover height.

The Berta Rotary Plough will work on Grillo walk-behind tractors that have at least 8.5 hp (petrol) or 7 hp (diesel) and 4x10x18” wheels or larger. Distance between wheels needs to be 14” to 18”(measured from the inside of one wheel to the inside of the other), and the closer you get to 18”, the better the plough will perform because it takes a bigger bite. Axle extensions may be required to achieve optimal working width on wheels.
