Tractor-mounted Spraying tanks Dal Degan

Dal Degan treatment sprayers are professional machines designed for spraying, weed control and the distribution of liquid fertilisers over medium to large agricultural surfaces. The brand was founded in 1870 by Antonio Dal Degan, who built an initial sulphur duster and a knapsack sprayer to protect his vineyard. The company developed motorised sprayers in the 1950s and introduced plastic models in the 1970s, following the expansion of agricultural mechanisation and the subsequent growth of the brand in Europe and international markets.

These tractor-mounted sprayers can distribute plant protection products, herbicides or liquid fertilisers according to the instructions for the formulation being applied. They are suitable for arable fields, horticultural crops, specialised plantations and open areas. The pump draws the mixture from the tank and delivers it to the distribution equipment, promoting even coverage and accurate output control.

This page also includes the main types of Dal Degan treatment sprayers, divided according to their intended agricultural application:

• Dal Degan spraying tanks: they distribute liquid mixtures over crops through different delivery devices. They can be equipped with spray cannons, multi-jet booms, hose reels and spray guns according to the required task;
• Dal Degan weed control tanks: they are intended for the controlled distribution of products used to contain weeds. Low-pressure pumps provide a flow rate suited to covering large open-field surfaces;

At AgriEuro, Dal Degan treatment sprayers can be selected according to their technical features, helping identify the model best suited to the surface, available tractor and intended agricultural application. The main elements to consider are:

• type of treatment: distinguishes spraying configurations from models designed for low-pressure weed control;
• pump and flow rate: the pump must correctly supply all delivery devices while maintaining a flow consistent with the working width and travel speed;
• operating pressure: it must be compatible with the installed nozzles, lances, booms and accessories, as well as with the instructions for the distributed product;
• tank capacity: this affects operating time between refills and the total weight applied to the tractor linkage;
• accessory configuration: spray cannons, multi-jet booms, spray guns and hose reels adapt distribution to the crop and the distance from the delivery point;
• tractor compatibility: hitch, PTO, power and lifting capacity must meet the requirements stated on the model specification sheet;

The available configurations are designed for professional work on farms, arable fields and specialised crops. Spraying models are suited to different crop treatments; weed control models are intended for ground application on open plots. The correct combination of pump, tank and delivery device supports accurate, continuous work.

The two families of Dal Degan sprayers meet different distribution requirements. The choice depends on the crop, mixture, surface and required delivery device. Each configuration must be paired with a compatible tractor and adjusted according to the operating instructions for the treatment.

Dal Degan spraying tanks are tractor-mounted units intended for distributing liquid mixtures in agriculture. The option to connect different accessories allows the machine to be prepared for targeted treatments, work along crop rows or long-range applications. Spray cannons and multi-jet booms increase the surface reached by the spray; guns and lances allow direct application to selected points. A hose reel makes work easier when the tractor must remain stationary or cannot approach the crop. Before choosing a model, check the tank capacity, pump flow rate, operating pressure and PTO compatibility. Terrain conditions and refill frequency also affect operation. Consistent adjustment of pressure, speed and nozzles promotes even distribution while limiting overlaps and untreated sections.

The available equipment allows the unit to be configured for different applications:

• spray cannon: directs the spray towards distant points or crops that are difficult to reach with a conventional boom;
• multi-jet boom: distributes the mixture through several delivery points along a defined strip;
• hose reel: facilitates operator movement during treatments performed with a lance or spray gun;
• spray gun: allows the spray to be manually directed towards the required section of the crop;

Dal Degan weed control tanks are designed to distribute mixtures over weeds in open fields and along the sections requiring treatment. Their distinguishing component is the low-pressure pump, paired with a flow rate suited to the required application width. This configuration supplies booms or other devices intended for ground treatment, maintaining flow along the travelled surface. Selection should consider the number and type of nozzles, boom width, tractor speed and volume distributed per unit of surface. Excessive pressure may produce finer droplets that are more exposed to drift; insufficient pressure may alter the spray pattern. Correct calibration therefore keeps flow rate and travel speed consistent. Before each application, also inspect filters, hoses, fittings and nozzles, following the instructions on the label of the product being applied.

The main operating components of weed control configurations include:

• low-pressure pump: supplies the circuit at values compatible with distribution through dedicated booms and nozzles;
• pump flow rate: it must be proportional to the working width, number of nozzles and travel speed;
• weed control boom: distributes the mixture along an even strip and must remain at the correct height above the target;
• nozzles: determine flow rate, spray pattern and droplet size, so they must be uniform and free from blockages;

The main difference concerns the pump, pressure and distribution device. Spraying tanks can be combined with spray cannons, guns, lances, multi-jet booms or hose reels and are suited to different crop applications. Weed control tanks instead use low-pressure pumps and normally supply booms with nozzles intended for ground application. The configuration must always be chosen according to the intended treatment, the instructions for the distributed product and the surface conditions.

Capacity should be selected by considering the surface to be treated, application volume per hectare and required operating time. A large tank reduces the number of refills but increases the weight carried by the tractor. The weight of the full sprayer must therefore be compared with the tractor’s lifting capacity and stability conditions. Also consider the distance from the filling point and access to the plots, rather than choosing the machine only by its nominal capacity.

Flow rate and pressure determine how the delivery devices operate. The flow rate must supply all connected nozzles or accessories, including the flow required by the agitation circuit. Pressure affects the spray pattern and droplet size. An undersized pump may produce uneven distribution; an oversized configuration requires correct control of the return flow. The values must match the specifications of the machine, nozzles and treatment.

Check the three-point hitch, PTO, required power and lifting capacity. The inspection must include the weight of the machine with a full tank, not only its empty weight. Rear dimensions, weight distribution and stability on sloping ground should also be considered. All mechanical and hydraulic connections must comply with the instructions in the specification sheet and sprayer manual.

Common accessories include spray cannons, multi-jet booms, hose reels, lances and spray guns. A spray cannon directs the jet over a distance; a multi-jet boom covers a strip through several delivery points. Hose reels, lances and guns allow manual work away from the tractor. Each accessory requires a suitable flow rate and pressure, so compatibility must be checked on the model specification sheet before purchase.

Even distribution requires matching nozzles, stable pressure and constant travel speed. Before starting, check the output of each nozzle and replace worn components or nozzles delivering a different quantity. The boom must remain at a consistent height above the target and stay stable during travel. Clean filters, correct mixture agitation and leak-free fittings also contribute to a regular spray pattern.

Nozzles should be checked before each work cycle and whenever the spray pattern appears irregular. Differences in output may be caused by wear, residue or blockages. Cleaning must be performed with suitable tools, without metal objects that could alter the opening. If a nozzle continues to deliver a different quantity from the others, replace it with a component of the same type and nominal flow rate.

Cleaning must follow the machine manual and the instructions on the label of the distributed product. The tank, pump, hoses, filters and nozzles must be rinsed in permitted locations while wearing the required protective equipment. Residues and rinsing water must not be discharged into waterways, drains or unauthorised locations. At the end, check that the circuit is empty and free from deposits.

A pressure drop may result from blocked filters, crushed hoses, leaking fittings, faulty valves or air entering the suction circuit. Before attributing the fault to the pump, inspect the complete liquid path from the tank to the nozzles. A damaged pressure gauge may also provide an incorrect reading. If preliminary checks do not identify the cause, inspect the pump and control unit according to the manufacturer’s procedures.

Before starting, check the tank seal, pump condition, filter cleanliness, hose integrity and nozzle uniformity. Also inspect fittings, valves, pressure gauge, transmission guards and the stability of the tractor connection. A test with clean water helps identify leaks or uneven spray patterns before preparing the mixture. Finally, adjust pressure, speed and application volume according to the treatment and applicable instructions.
