A sprayer can fit between your trees and still be too long to turn at the end of the row. On another farm, turning may be easy, but every refill means a long drive back to the water point.
Start with the problem that slows your crew down most. A tracked orchard sprayer gives you a self-propelled option. A mounted air-blast sprayer uses a tractor you may already own. A trailed model adds tank capacity when refilling is the main bottleneck.
Shortlist a tracked sprayer if you need to spray without tying up a tractor. Verify row clearance, turning space, and where the operator can stand.
Shortlist a mounted air-blast sprayer if your tractor can power and carry the loaded unit. Check that the complete setup can turn at the row ends.
Consider a trailed air-blast sprayer if refills interrupt long spray runs. Check that the tractor and trailer can clear your tightest turns.
Verify canopy coverage on each candidate. Tracks describe how a sprayer moves. Air-blast describes how a fan carries droplets toward the trees.
Setup | Power and attachment | GRANDEMAC example | First fit check |
|---|---|---|---|
Self-propelled tracked | Dedicated tracked chassis with electric drive | Orchard Plant Protection Robot, 350 L | Row clearance and operator position |
Three-point mounted air-blast | Tractor PTO powers the sprayer. The rear linkage carries it. | FXS7/340, 300 L | Loaded lift capacity and rear clearance |
Trailed PTO air-blast | Tractor PTO powers the sprayer. A drawbar pulls its wheeled chassis. | FQS Series, 600 or 1,000 L | Drawbar compatibility and the trailer’s turning path |
These capacities describe the specific GRANDEMAC configurations. Use them to compare refill plans for the same block and target spray volume.
Start here if your tractor is usually busy with mowing or transport when the spray window opens. GRANDEMAC’s tracked orchard sprayer is self-propelled and supports wireless remote operation. It can handle the spraying job without taking a tractor off another task.
Check the route with a representative load. Walk it first and note low branches, narrow gates, and uneven ground. Decide where the operator can monitor row entry and turns while staying within the model’s control limits. For an electric machine, include the charging location and available charging time in the work plan.
A tractor-mounted air-blast sprayer makes sense when a compatible tractor is available during spraying. The GRANDEMAC FXS7/340 carries 300 L and mounts to the rear three-point linkage. The tractor’s PTO drives the sprayer, and an axial fan directs droplets toward the canopy.
The FXS7/340 calls for at least 35 hp. Also confirm the hitch, PTO requirements, and lift capacity with the tank loaded. Check axle loads and any ballast required by the tractor manual. Measure the complete tractor and sprayer together, including how far the sprayer extends behind the rear axle.
A trailed orchard sprayer may suit blocks where refilling cuts into a short spray window. The GRANDEMAC FQS Series offers 600 L and 1,000 L configurations. Its wheeled chassis carries the tank and spray assembly, and the tractor supplies PTO power.
Compare the time saved on refill trips with the space needed to maneuver. Watch where the trailer wheels track as the tractor turns into the next row. A fence, ditch, or trellis post near the corner can limit access even when the tractor itself clears it.
Measure the clear space between branches or posts at the narrowest point. Then measure the headland, the open area where the machine turns at the end of a row. Check both ends of the block, including turns next to fences and gates. Ask for a turn demonstration with the working configuration when possible.
Choose trees that reflect your canopy height and density. Run a clean-water demonstration and check droplet marks on water-sensitive paper at the top, middle, and bottom. Put papers near the outside leaves and farther inside. Compare the pattern across positions, especially where the foliage is thickest.
Use your calibrated spray volume and the block area to estimate the liquid needed per job. Compare refill stops, travel time to water, and time spent mounting the sprayer or preparing the tracked unit. If your orchard has several blocks, check the route between them as well as the spray rows.
Choose the sprayer that can clear your tightest turn, reach your target canopy, and finish the block within the time your crew has. A tracked orchard sprayer is worth testing when tractor availability limits the schedule. A mounted air-blast unit can fit an existing tractor workflow, while a trailed model can help when refill trips take up too much of the spray window.
Compare Sprayers for Your Orchard Layout
That depends on the model, ground conditions, and obstacles at each row end. Verify the turning path with a working load, including any parts that extend past the track width.
It depends on the spray assembly. Tracks describe the drive system. Check whether the model uses a fan to move droplets, then verify deposition in your canopy.
Also verify the rear linkage, PTO setup, and lift rating at the sprayer’s load position. Confirm axle loads and ballast requirements with the tank filled to the planned working level.
Check the model’s limits for the planned direction of travel and tank load. Evaluate turns and side slopes separately. Confirm the operating limits in the machine manual before scheduling a field trial.
It can save time when refill trips are frequent and the water point is far away. Check whether the larger setup can still enter and leave the rows without slow or repeated maneuvers.
