Orchard spraying is a demanding task that requires precision, efficiency, and operator safety. Remote-controlled tracked sprayers have become the preferred solution for many orchardists, allowing precise chemical application without exposing operators to chemicals or harsh terrain. This guide helps you select the right model for your orchard.
1. Why Remote-Controlled Sprayers?
- Operator safety: Operator stays away from chemicals and spray drift
- Precision: Remote control allows precise targeting of specific trees or rows
- Terrain capability: Rubber tracks provide excellent stability on slopes and uneven ground
- Efficiency: Wide spray coverage (up to 16m) and large tank capacity (up to 500L)
- Compact size: Narrow chassis (as low as 40cm) fits between orchard rows
2. GTFI Remote-Controlled Sprayer Range

3WYF Series – Wider Coverage, Larger Capacity
- 3WYF-120: 120L tank, 12m spray, 6hp gasoline, 52cm chassis width
- 3WYF-300: 300L tank, 16m spray, 12.5hp gasoline, 90cm chassis width
- 3WYF-400: 400L tank, 12m spray, 13.6hp diesel, 90cm chassis width

- 3WYF-330: 330L tank, 6m spray, 12.5hp gasoline, 90cm chassis width – high-clearance design
3. Selection Guide – Key Factors
3.1 Orchard Row Spacing
The most critical factor is whether your sprayer can fit between orchard rows:
- Narrow rows (≤1.2m): Choose 3WYP-100 (40cm chassis) or 3WYF-120 (52cm chassis)
- Standard rows (1.2–1.8m): Choose 3WYP-200 (70cm chassis) or 3WYF-300 (90cm chassis)
- Wide rows (>1.8m): Any model fits – choose based on capacity and spray width
3.2 Tank Capacity – Match to Orchard Size
- Small orchards (< 5 hectares): 100–200L (3WYP-100, 3WYP-200)
- Medium orchards (5–15 hectares): 300–400L (3WYF-300, 3WYF-400)
- Large orchards (> 15 hectares): 500L (3WYF-500) or multiple units
3.3 Spray Width and Height
- 7m spray width: Suitable for narrow rows and low trees
- 12–14m spray width: Versatile for most orchards
- 16m spray width: Best for wide rows and large trees
- Spray height: Models range from 5.5m to 10m – choose based on tree height
3.4 Engine Type – Gasoline vs Diesel
- Gasoline: Lighter, lower initial cost (Lonxin 170: 4.4kW/6hp; Lonxin 190: 9.2kW/12.5hp)
- Diesel: More fuel-efficient, longer lifespan (Changfa 192: 8.5kW/11.5hp; Yanmar 195: 9.5kW/12.9hp)
- Both are Euro 5 compliant
3.5 Remote Control Distance
All GTFI remote sprayers offer ≥100m control distance. The 3WYF-500 extends to 200m, ideal for large orchards.
3.6 Track Width and Terrain
- 10cm tracks: Lightweight, minimal soil compaction (3WYP-100, 3WYF-120)
- 12–15cm tracks: Better stability for medium models (3WYP-200, 3WYF-300)
- 18cm tracks: Maximum stability for large models (3WYF-500)

5. Nozzle Configuration
GTFI sprayers are equipped with 8–18 nozzles, fully customizable based on your orchard type:

- 12–14 nozzles: Standard configuration for most orchards
- 16–18 nozzles: Maximum coverage for large trees and wide rows
Orchard Conditions
Orchards often require maneuverability, slope control, row access, spray reach, and remote operation. Check turning space, ground conditions, control range, and safe chemical handling procedures.
What to Confirm Before Ordering
- Define crop type, crop height or row spacing, terrain, field size, and expected working season.
- Compare working width, tank or hopper capacity, operating speed, and expected field productivity for the actual application.
- Check engine or motor power, fuel type, starting method, transmission, tires or tracks, and ground clearance where relevant.
- For spraying equipment, specify pump flow, pressure range, nozzle type, boom width, filtration, and chemical compatibility.
- Confirm cleaning, spare parts, wear components, operator controls, transport dimensions, and local regulations before purchase.
For a quotation request: For an agricultural quotation, provide the crop, working area, terrain, desired capacity, power source, destination country, and quantity. Photos or field dimensions are useful when the application is unusual.
