PG Forcing Tub vs. HD Forcing Tub
PG Forcing Tub vs. HD Forcing Tub – A forcing tub acts as the funnel of your cattle handling system, using natural cattle behaviour to encourage movement into the race. Choosing between the PG Forcing Tub and the HD Forcing Tub comes down to herd size, handling frequency, and required automation.

1. Model Overview
PG Forcing Tub (Standard Duty)
Target Operation: Small to medium suckler, pedigree, or commercial herds (up to 250 head).
Key Mechanism: Manual ratchet-operated crowd gate with a spring-loaded latch running along a heavy outer ring frame.
Steel Finish: Pre-galvanized frame construction with heavy-duty slide gates.

HD Forcing Tub (Heavy Duty & Pneumatic Ready)
Target Operation: Large commercial finisher yards, dairy units, and high-throughput livestock enterprises (250+ head).
Key Mechanism: Heavy-duty rotary crowd tub with anti-back ratchet mechanisms, optional pneumatic gate automation, integrated top-walkway, and modular drafting integration.
Steel Finish: Hot-dipped galvanized construction for long service life.

3. Flight-Zone Science: Why Curved Sheeted Tubs Work
Both the PG and HD tubs rely on Dr. Temple Grandin’s livestock handling principles:
Circular Motion: Cattle moving through a 180° sweep think they are returning to where they came from.
Visual Blind Barriers: Sheeted side panels prevent stock from seeing handlers, dogs, or machinery outside the tub, keeping their eyes focused on the open entry to the race.
No Dead Ends: The curved radius avoids 90-degree corners where flighty animals tend to bunch up or stall.
