The walking tractor is an agricultural machinery suitable for various horticulture and gardening jobs, as it facilitates operations such as tillage of the land and the grass cutting and replaces hand tools as a spade and hoe on large plots.
This equipment is powered by a petrol or diesel engine, which delivers a maximum power of around 15 horsepower to a single crankshaft, and is maneuvered by the operator using a handlebar with vertically and laterally adjustable handlebars. The machine moves on two traction wheels, generally equipped with a differential.
The "two-wheeled tractor" is easily usable from both hobbyists both from professionals and it is the right machine to carry out many activities scheduled during the year, from the preparation of the seedbed to the care of the greenery in vegetable gardens or gardens, up to the mowing of inter-row spaces or uncultivated areas. The versatility and multifunctionality of the two-wheel tractor are due to the possibility of combining it with it different types of equipment.
In fact, a two-wheel tractor can have various accessories, carried or towed by the vehicle and operated thanks to the power take-off. The power take-off is the part that transmits the movement of the engine to the accessory. Sometimes it is independent of the gearbox, available with more forward gears, more reverse gears and reverse gear. The equipment most commonly attached to the "two-wheeled tractor" are the tiller, the plow, the furrower, the rotary harrow for working the soil, the cutter bar, the lawn mower, the mulcher for cutting the turf.
In some cases, other agricultural machinery (seeders, sprayers and, if the machine is equipped with a rear axle with seat, small towed trailers) or tools unrelated to the agricultural sector are combined with the tiller, such as snowplow blade or turbine, sweepers, pumps is generators of electric current.
Two-wheel tractor and tiller: a winning couple
Among the tools for the walking tractor the most used is certainly the tiller, which is generally supplied as standard by purchasing the agricultural machinery. The cutter is in fact a rotor with knives, each of which mounts four hardened steel blades. The rotating movement of the knives allows the clods to be chopped in an optimal way so as to make the soil soft and easily penetrated by the roots of the cultivated vegetables.
When it is necessary to prepare the soil for sowing, mechanically eliminate the weeds or weed the space between the rows of vegetable crops, it is advisable to use a cutter with quick coupling, which can be installed on the walking tractor without using tools.
The cutters are capable of milling a different widths (between 30 and 80 centimeters) and depth. Depending on the working width, the attachments require between 5 and 12 horsepower. The milling depth is set by means of a specific lever, which is external to the hood and acts on the central knife so that the tools work best on clayey, medium-textured or sandy soils.
Sturdy cutters equipped with transmission with gears in oil bath, which stays clean thanks to special protections. Another component often present on the tiller blades is the hood enveloping, which can be fixed or adjustable and allows to contain the worked soil. Often free from routine maintenance, the available models can also be equipped with some options, including the support wheel to facilitate the transport of the walking tractor and the rear furrower.
To tilling the soil, the rotary tiller can be used as an alternative to the walking tractor equipped with the tiller. Find on Orto Da Coltivare a comparison between tiller and walking tractor.
Plow, a classic for tillage
The plow allows you to prepare the soil for subsequent operations and also to bury the residues of previous crops or weeds, allowing them to decompose. It is possible to match a small plow to the walking tractor, which however must be characterized by a fair amount of power and be equipped with ballast, widened wheels to ensure good results.
The plow for the "two-wheel tractor" can be of three types:
- Single share plow. This type of plow operates with a single share and a coulter (mounted in an anterior position with respect to the share) for cutting the soil, as well as with a moldboard for the lateral turning of the slice of earth and the creation of the furrow. The tool is designed to ensure that the soil turns only to the right or only to the left of the direction of travel. It has a working width of about 20 centimeters. The plowing depth, the height of the working parts and the working angle are adjustable by means of special screws or levers.
- 180 degree ear turn. This plow uses two mouldboards, which are installed on the same rudder in 180 degree opposite positions and work one at a time. Like the single share plow, the turn-ear plow for walking tractor also plows about 20 centimeters at each pass.
- Rotary plow. Capable of plowing and milling in a single pass, the rotary plow is suitable for increasing soil permeability, destroying weeds, making furrows and working all those areas where conventional plows cannot reach. With gear transmission in oil bath and with adjustable operating depth, the tool loosens wider widths than other plows (about 25 centimeters) and needs a power of at least 8 horses.
Another very useful application for the vegetable garden is the spading machine for two-wheel tractor or motor spade: a machine that allows you to mechanize the same work that takes place with the classic spade and to obtain a soil worked in a different way from the tiller, particularly useful for agriculture. biological.
Perfect grooves with the coulter
Another equipment that can be combined with the walking tractor to open furrows or gutters and to perform tamping after working the soil is theopener, proposed in the versions adjustable or adjustable back.
The adjustable model has a V-shaped body to break the soil and two moldboards with adjustable opening to create the furrow in the plowed soil, while the retrofitted model is so called because it operates simultaneously with the tiller, helping to create furrows ideal for sowing and irrigation.
The depth of penetration and the working angle of the furrower, which requires the assembly of ballasts on the walking tractor, can be adjusted by acting on tie rods and screws. The width of the furrows, which reaches 40 or 60 centimeters depending on the model, depends on the degree of opening of the moldboards.
Two-wheel tractor and cutter bar for mowing grass
When combined with a cutter bar, the walking tractor is transformed into a machine also suitable for mowing grass. On the market there are bars for walking tractors equipped with devices for setting the cutting height and capable of cutting all types of turf thanks to the assembly of different cutting units, each characterized by various working widths (generally between 80 and 210 centimeters).
Based on the characteristics of the grass to be cut, operators can choose central cutter bars, double blade with double reciprocating movement, with blade holder traditional or with semi-fine teeth. The bars equipped with two blades that move in the opposite direction to each other are distinguished by the reduction of vibrations transmitted to the handlebar and by the high cutting quality.
The blade holders are made of an elastic material and allow the blade to always adhere optimally to the teeth, while the teeth are made of special heat-treated steel and have high wear resistance, as well as a considerable duration. Another fundamental component of the cutter bars is the safety clutch, which intervenes when foreign bodies hinder the operation of the blades and prevents damage to the cutting equipment.
Two-wheel tractor for lawn care
To avoid buying a dedicated lawnmower, it is also possible to attach a lawn mowers, which allows the green areas of vegetable gardens and gardens to be kept in excellent condition. Lawn mowers for walking tractors can be equipped with asingle blade (with a cutting width of about 50 centimeters) or two pivoting blades (with a cutting width of 100 cm) and be equipped with the basket for grass collection. Clearly, the double blade models require more power (equal to at least 10-11 horsepower), while those without the basket unload the material cut laterally leaving it in place.
The mowers for walking tractors on the market are durable thanks to the steel structure, reliable thanks to the gear transmission in oil bath and safe thanks to automatic blade brake.
Other important components of the tools are the adjustable front wheels for the horizontal adjustment of the cutting apparatus, the lever for quickly setting the distance of the blades from the ground and therefore the cutting height, the blade holder discs for minimizing damage caused by impacts or kickbacks.
The lawn shakes with the grass cutters
For the arrangement of uncultivated areas, the destruction of plant residues and weeds in the inter-row spaces, the cutting of tall grass comes into play the walking tractor combined with a grass cutter, which can only be equipped with one rotor with mobile knives or a single one lama.
Generally powered by diesel engines and equipped with pivoting front wheels, the single-rotor flail mower uses an oil bath gear transmission and a roller with Y-shaped knives (or lawn mower palette) to cut widths of 60-110cm and even shred pruning shoots, which are subsequently deposited on the ground. Also in this case, the cutting height is adjustable by means of a crank.
With gear transmission in oil bath and pivoting front wheels, the single-blade shredder allows you to cut widths of about 80 centimeters, deposit the chopped material on the ground, optimally follow the contour of the ground and adjust the cutting height. All requiring a power of approx 10 horses.
