tractor-mountedtrailer-mountedfor tractors

Overview
A compact, cost-effective trencher designed for restricted spaces such as orchards, vineyards and greenhouses. Powered by a 30+ HP tractor, the AFT45 improves drainage on waterlogged fields and can increase usable yield by 25–35% when properly applied.

The AFT45 at a glance

• Compact trencher: suitable for use with a 30+ HP tractor
• Flexible scheduling: operate when soil and weather conditions allow
• Ideal for restricted spaces: orchards, vineyards, greenhouses and narrow access areas
• Cost-effective alternative: lower investment compared with self-propelled trenchers
• Easy transport: suitable for transport on a trailer
• Clean, narrow trench: minimal surface disturbance
• Simple backfilling: auger deposits spoil to one side; a tractor blade can backfill
• Options: soil conveyor (discharge height 1.5 m) and automatic laser grading

Main Features & Components

• Maximum Depth:
  • Standard boom: 0.8 m, 1.0 m or 1.2 m
  • Narrow boom: 0.6 m or 0.8 m
• Width:
  • Standard boom: 125–200 mm
  • Narrow boom: 60–84 mm
• Chain or wheel fitted with soil blades or tungsten-tipped carbide teeth
• Soil auger to place spoil to the trench side
• Optional soil clean-up conveyor system (discharge height 1.5 m)
• Optional (automatic) laser grading equipment
• Weight: approx. 400 kg with auger; approx. 480 kg with conveyor

Tractor Requirements

• 30+ HP with CAT I 3-point linkage
• Hydrostatic transmission or creeper gearbox (recommended minimum speed 50–100 metres/hour)
• 3-point linkage (CAT I)
• 1 set of feed/return spool valves (2 sets required if using a conveyor)
• 540 RPM PTO

Performance & Operating Notes
Trenching speed depends on ground conditions, trench depth and width. Typical speeds in normal conditions range from approximately 75 to 150 metres per hour (slower in stony ground, faster in sandy ground). Component wear varies with soil type and operating conditions.
