You've hit on a crucial point for evaluating practicality-these key performance indicators (KPIs) directly determine how well the rotary tiller adapts to your small loader and on-site tasks! Below are the core KPIs to focus on, with clear relevance to operation efficiency and equipment protection:
1. Tilling Efficiency Indicators
These metrics reflect how fast and effectively the tiller completes soil preparation.
Tilling Width: Ranges from 1000–1930mm for small loaders. Narrow widths (1000–1200mm) suit tight spaces (greenhouses/orchards), while wider options (1400–1930mm) boost efficiency for open small plots.
Tilling Depth & Adjustability: Common range is 60–200mm; ideal models offer stepless adjustment (via skid shoes or hydraulic control) to match crop needs (100–150mm for vegetables, 150–200mm for deep plowing).
Working Speed: Depends on hydraulic flow (15–30 GPM); stable rotation speed (200–300 RPM for tines) ensures uniform soil crushing without clogging.
2. Soil-Crushing Quality Indicators
These determine the suitability of the tilled soil for planting.
Clod Size: High-performance tillers produce ≤50mm clods (ideal for seedbeds); models with dense, hardened steel tines (38+ pieces) or serrated designs perform better on clay/rocky soil.
Soil Uniformity: Reflected by tine arrangement (helical layout is optimal) and reversible rotation-ensures no unturned patches and even mixing of fertilizers.
3. Compatibility & Durability Indicators
These link directly to the small loader and long-term use.
Hydraulic Adaptability: Required flow (15–30 GPM) and pressure (1500–3000 psi) must match the loader's auxiliary hydraulic output (critical to avoid stalling or motor burnout).
Weight & Connection: Tiller weight (120–300kg) must be within the loader's lifting capacity; quick-attach compatibility (universal/Bob-Tach) ensures easy installation without modifications.
Structural Durability: Reinforced steel frame, corrosion-resistant coating (for humid/acidic soil), and replaceable hardened steel tines (wear-resistant, extend service life).
4. Operational Convenience Indicators
These reduce operator effort and downtime.
Adjustment Ease: Quick-access depth controls (manual/hydraulic) and tool-free tine replacement save maintenance time.
Anti-Clog Performance: Reversible tine rotation and debris-discharging design prevent jams when tilling weedy or wet soil.
Vibration Damping: Shock-absorbing brackets reduce vibration transfer to the loader, protecting hydraulic components and improving operator comfort.
