AFT 45 Tractor mounted trencher

The AFT 45 Tractor mounted trencher is a strong lightweight trencher to fit onto Compact tractors of 20 to 45 hp (15-34 kW).

Designed specifically for the sportsturf industry, it is very versatile and equally at home in the agricultural, domestic and industrial pipe and cable laying markets.

The AFT 45 can be fitted with various digging chains, or a high performance slitting wheel for narrow, shallow trenches and optionally with total soil clean up and removal system.

Mounted on compact tractors with creep speed drive or hydrostatic transmission, the AFT 45 multi-purpose trencher costs only a fraction of the price of equivalent self-propelled machines.

THE IDEAL COST-EFFECTIVE TOOL FOR ALL SPORT FACILITIES WISHING TO INSTALL OR EXPAND EXISTING DRAINAGE AND IRRIGATION SYSTEMS.

IT OFFERS:

• Neat and economical high speed trenching.
  
  
• A wide range of trench sizes: From 125 to 200mm wide and up to 1.2 metres deep with digging boom and chain.
  
  
• A high speed soil slitting wheel for very narrow trenches from 40 to 100mm wide and up to a depth of 450mm.
  
  
• A sportsfield clean up system which clears up all the soil, elevating it to vehicles running alongside. It works with both digging chains and the slitting wheel and folds up for road transport.
  
  
• 63.5mm pitch fully detachable heavy duty digging chain.
  
  
• Continuously variable hydraulic depth control.
  
  
• Optional laser grading linkage and solenoid guided depth control for use with lasers for accurate drainage grading.
  
  
  
  

SPECIFICATIONS  

DIGGING CHAINS
63.5mm Heavy duty chain offering for trenches of 125, 150 or 200mm wide. Being fully detachable, individual links are easily and economically replaced.

TRENCH SLITTING WHEEL
The totally enclosed, large diameter digging wheel is fitted with ten angled pockets, each one rigidly supporting a digging blade, which then only needs a spring pin to hold it firmly in place. For hard conditions, double pointed tungsten carbide teeth can be fitted in some or all of the pockets. For trenches of 40, 50, 60, 70 or 100 mm wide and up to 450mm deep.

DIGGING BLADES AND TEETH
Silicon manganese austempered spring steel with hard faced edges. Optional tungsten carbide picking teeth are available for hard or abrasive conditions. The pocket mounted digging blades of the sandslitting wheel are fully reversible, which doubles their working life and thus greatly reduces operating costs.   

DIGGING BOOMS
Choice of three digging booms to dig from ground level down to maximum depths of 0.8, 1.0 or 1.2 metres.

TRANSMISSION
The digging chain and the slitting wheel are driven by the tractor PTO shaft through an adjustable torque limiting safety clutch and right angle gear box. A secondary roller chain drive powers the slitting wheel.

SOIL CLEAR UP SYSTEM
Soil retaining plates guide the dirt onto a hydraulically driven cross-flow and elevating conveyer mounted across the front of the digging chain or the slitting wheel, leaving a clean surface. The conveyor can be folded away when the trencher is transported.

DEPTH CONTROL
Hydraulically controled, using the tractor's hydraulic power system. Controls range from manual by means of the tractor valve lever to automatic laser operated solenoids, depending on the specification.

 
TRACTOR REQUIREMENTS
Power: 20 to 45 hp (15 - 34 kW).
Three-point linkage: category 1 or 2. PTO shaft 540rpm. A hydrostatic transmission or a creep speed gearbox with at least a 10:1 reduction is required. Front mounted balance weights are recommended (particularly on lighter tractors or if the soil clear up system is fitted). A hydraulic supply of at least 10 litres/minute at 150 Bar is needed for the conveyor system.
