Frequently Asked Questions
Orchard Sprayers
Airblast orchard sprayers with high air volume and adjustable vanes provide the best penetration into dense canopies. Models with axial fans generally offer stronger, uniform airflow.
For 30–100 hectare orchards, 1500–2000 L tanks are preferred, reducing refill time and improving efficiency.
Yes. Most orchard sprayers offer multi-speed gearboxes or hydraulic controls that allow airflow adjustment for different crops like apple, peach, pear, or citrus.
Use low-drift nozzles, reduce airspeed, lower boom height, and spray during early morning or late afternoon when wind is calmer.
- Axial: Higher air volume, best for tall and dense orchards.
- Radial: More focused airflow, lower drift, ideal for vineyards and low-canopy trees.
Yes. Trailed units can be equipped with wide-profile tyres and low center of gravity for safer operation on slopes.
Most orchard sprayers require 40–90 HP, depending on tank capacity and fan diameter.
Fuel consumption depends on tractor load but typically ranges 3–6 liters per hour.
Yes. All professional orchard sprayers include anti-drip diaphragm nozzles to prevent chemical wastage.
Annual maintenance is minimal: pump service, filter cleaning, oil change for the gearbox, and periodic nozzle replacements.
A Holsan orchard sprayer is a PTO‑driven machine designed to apply plant protection products and foliar feeds uniformly in fruit orchards, using a calibrated pump, tank, and nozzle system to deliver controlled spray volumes to tree canopies.
For tall, dense canopies Holsan air‑assisted or airblast orchard sprayers are recommended, as their high‑capacity fans and vertical air throw help carry droplets to the upper parts of the trees.
Estimate the number of hectares or decares treated per filling, the typical water volume per hectare for your crop, and your tractor power, then choose a Holsan tank capacity that completes most of your orchard in one or two fills without overloading the tractor.
Calibration should be done at least at the start of every spraying season and whenever there is a change in product, nozzle size, travel speed, or pressure to ensure accurate application rates.
Routine care includes rinsing the tank after use, flushing lines and nozzles, checking filters, hoses and seals for leaks, greasing moving parts, and winterizing the machine if it will be stored in freezing temperatures.
Vineyard Sprayers
Compact airblast or tunnel-type vineyard sprayers with narrow chassis are ideal for row widths of 1.8–2.2 meters.
Yes. Vineyard sprayers feature adjustable louvers and multi-speed fans to fine-tune air intensity.
For small to mid-size vineyards, 600–1000 L sprayers offer the best balance of capacity and maneuverability.
Yes. Airblast vineyard sprayers are designed with dual-sided nozzle towers for symmetrical coverage.
Yes. Mounted sprayers are most suitable for steep terrain due to low weight and increased tractor stability.
Some advanced models support optional electrostatic systems to improve adhesion and reduce chemical use.
Vineyard sprayers with radial fans and controlled airflow provide excellent drift control, meeting EU standards.
Most professional sprayers use brass or stainless steel nozzle holders for durability and corrosion resistance.
Compact Holsan tractor‑mounted or small trailed vineyard sprayers with adjustable track width and low overall height are ideal for narrow row spacings and sloping vineyards.
Set nozzle orientation to face both sides of the canopy, match pressure and travel speed to the nozzle chart, and adjust air output (for air‑assisted models) so leaves move slightly without excessive turbulence.
Yes, Holsan vineyard sprayers can apply most approved crop protection products as long as the operator follows label directions, uses compatible materials, and cleans the system thoroughly between different products
Airblast Sprayers
Fans typically range 700–920 mm, generating 20,000–55,000 m³/h air volume depending on model.
- Axial: Heavy airflow (oranges, apples, tall trees)
- Radial: Lower drift and precise airflow (grapes, berries)
High-volume axial fans with 3-speed gearboxes provide excellent penetration up to 6–8 meters height.
Yes. Most units include 2–3 gearbox speeds for adjusting turbine RPM.
Professional sprayers maintain 200–300 micron droplet size, ideal for orchards.
Reputable brands such as Comet, Udor, or Annovi Reverberi ensure long lifespan and reliability.
A Holsan airblast sprayer uses a powerful fan to blow spray droplets into tree or vine canopies, making it suitable for orchards, vineyards, and high‑value perennial crops that need deep penetration and good coverage.
Fan speed should be high enough to move foliage and carry droplets through the canopy, but not so strong that it blows spray past the target; operators usually start at the manufacturer’s recommended PTO speed and fine‑tune in the field.
Most Holsan airblast sprayers are compatible with hollow‑cone or twin‑fan nozzles, which produce fine to medium droplets.
Mounted Sprayers
Mounted sprayers range from 200 L to 1200 L depending on tractor capacity.
Quick-coupling systems allow single-operator mounting within minutes.
Yes. Most models include hydraulic or venturi-type agitation for uniform chemical mixing.
Both options are available. Hydraulic booms improve efficiency and reduce operator fatigue.
Booms typically range 6–18 meters, depending on tank size.
Yes. Modern mounted sprayers support GPS section control to reduce overlap and chemical waste.
A Holsan mounted sprayer is carried on the tractor’s three‑point linkage and connected via PTO shaft and hydraulic or electrical controls, allowing the operator to lift, transport, and operate the sprayer directly from the tractor seat.
Mounted sprayers are usually preferred on smaller to medium farms, in tight headlands, or on sloping and uneven fields where maneuverability and stability are more important than very large tank capacity.
Required horsepower depends on tank size, pump capacity, and boom width, but in general the tractor must safely lift the full tank weight and provide adequate PTO power for the pump and any fan or hydraulic functions.
Trailed Sprayers
Typical capacities include 1000, 1500, 2000 liters
Standard options range 12–24 meters.
Yes. Mid- and high-end models include anti-shock suspension for stability during high-speed spraying.
Yes. Optional electronic rate controllers maintain consistent application rates regardless of speed.
A minimum of 70–120 HP is usually required depending on tank size and terrain.
A Holsan trailed sprayer is pulled behind the tractor on its own axle, offering larger tank capacities and wider booms for medium and large farms that need to cover many hectares efficiently.
Most Holsan trailed sprayers are designed with lighting, brakes, and hitch systems that comply with typical agricultural transport standards, but operators must always check local regulations and secure the boom and tank before road travel.
Key tasks include checking wheel bearings and tyres, inspecting the drawbar and hitch, maintaining the pump and filters, and keeping the boom, hoses, and nozzles clean and free from damage or leaks.
Tractor-Mounted Sprayers
Mounted sprayers typically require 30–90 HP, depending on weight and boom size.
Proper PTO speed (usually 540 RPM) ensures correct pump pressure and consistent droplet size.
Yes. High-quality models include anti-vibration dampers and reinforced boom arms.
Yes. Both systems can be added to improve spraying precision.
A Holsan tractor mounted sprayer offers good maneuverability, quick hitching, and efficient coverage for mixed crops, often at a lower investment cost and with less storage space than very large trailed machines.
Check the tractor’s lifting capacity, PTO power, and hydraulic outlets, then select a Holsan model whose full tank weight and boom width fall safely within those limits.
With the right boom or air‑assisted configuration, a Holsan tractor mounted sprayer can treat row crops, orchards, and vineyards, making it a flexible choice for diversified farms.
Jet Sprayers
Jet sprayers can reach 15–25 meters, depending on pressure and nozzle configuration.
Yes — they are specifically designed for tall orchards such as walnut, pistachio, hazelnut, and citrus.
Jet sprayers focus the spray stream to minimize drift, but wind conditions must still be considered.
High-pressure diaphragm or piston pumps are required to achieve long-distance jet performance. Holsan sprayers use Imovilli and Udor pumps
A Holsan jet sprayer uses high‑pressure jets to project spray over a distance, making it useful for tall trees, spot treatments, and areas that are difficult to reach with standard booms.
Operators should set pressure only as high as needed for reach, choose appropriate nozzle sizes, and move the lance or outlet steadily to avoid concentrating spray in one spot, always respecting label dose rates.
General Agricultural Sprayers
200 L–800 L for mounted/trailers; 1000–2000 L for field sprayers.
UV-resistant polyethylene tanks, polyester tanks, stainless steel booms, and brass or ceramic nozzles for durability.
Modern nozzle layouts ensure excellent horizontal and vertical distribution.
Use low-drift nozzles, lower pressure, and avoid spraying in high wind.
Pumps, filters, booms, valves, and nozzles are widely available through service partners and distributors.
Holsan typically offers a range that includes tractor‑mounted, trailed, orchard, vineyard, airblast, and jet sprayers so farmers can match the machine to crop type, field size, and terrain.
Calibration involves measuring travel speed, nozzle output, and boom or spray width, then adjusting pressure or nozzle size so that the actual application rate matches the target rate given on the product label.
Operators should wear appropriate personal protective equipment, follow chemical label instructions, avoid spraying in strong winds, and clean and store the Holsan sprayer so residues do not pose risks to people, animals, or the environment.
