Common rail BackPac

Product overview
The BackPac is a lightweight slurry applicator designed for umbilical slurry systems to enable wide-area application with minimal soil compaction. Available as a dribble bar (BackPac) or trailing shoe (BackPac Slide), it provides precise slurry placement and high coverage while replacing the need for heavy tankers.

Problem / Solution
Problem: Heavy tankers and conventional spreaders compact fields, produce uneven nutrient lines ("V-track") and increase downtime and operating costs.
Solution: The BackPac uses an umbilical delivery concept with automatic control, precision macerators and dribble bar or trailing shoe applicators to ensure even distribution, low ground pressure and reduced service requirements.

Key advantages

• Soil conservation – low ground pressure reduces compaction and protects yields.
• Precise distribution – ExaCut macerators ensure consistent flow (manure flow stabilised within 2 seconds) and prevent start-up V-patterns.
• Early season operation – lightweight design and umbilical layout allow use in wetter conditions.
• Maintenance efficiency – UV-resistant hoses and maintenance-free joints lower downtime; optional QuickService for ExaCut ECQ speeds up service.

How it achieves uniform nutrient distribution

• Two precision distributors (ExaCut ECL or ECQ) balance flow and optimise centre of gravity.
• Equalised hose routing with matched hose lengths to synchronise outlet times.
• Comfort Flow Control enables group-wise hose control for balanced application across the width.

Models

• BackPac (dribble bar) – working width 21–32 m; applies slurry directly to the crop canopy for flexible field use.
• BackPac Slide (trailing shoe) – working width 21–30 m; places slurry under crop canopy for dense vegetation and targeted placement.

Working width comparison

• 21 m — folded width 18 mm; 2 macerators; shoe spacing 26.25 cm; Weight (BackPac) 2,950 kg; (BackPac Slide) 3,150 kg.
• 24 m — folded width 21 mm; 2 macerators; shoe spacing 25–30 cm; Weight (BackPac) 3,000 kg; (BackPac Slide) 3,200 kg.
• 27 m — folded width 24 mm; 2 macerators; shoe spacing 28.13 cm; Weight (BackPac) 3,250 kg; (BackPac Slide) 3,450 kg.
• 30 m — folded width 27 mm; 2 macerators; shoe spacing 31.25 cm; Weight (BackPac) 3,300 kg; (BackPac Slide) 3,500 kg.
• 32 m (BackPac only) — folded width 30 mm; 2 macerators; shoe spacing 33.33 cm; Weight (BackPac) 3,450 kg.

Maintenance / Service
Hoses are made from UV-resistant special plastic with high wear resistance and maintenance-free joints reduce service intervals. Passive levelling protects components against ground contours. The QuickService option for ExaCut ECQ reduces exchange time and overall downtime.
