Long straw typically demands more power due to the increased resistance in the chopping and blowing processes. As a general rule, processing long straw requires approximately 20-30% more power than short straw of equivalent volume.
For example, a mid-range straw blower processing short straw might operate efficiently with a 60-80 HP tractor, while the same machine handling long straw could require 80-100 HP to maintain similar throughput. It’s crucial for operators to consider these power differentials when selecting equipment or planning operations to ensure their tractors can meet the demands of their chosen straw blowing system.
Feed rate and processing capacity comparisons
Feed rate and processing capacity are critical factors in determining the overall efficiency of a straw blower. These metrics can vary significantly between long and short straw applications. Long straw typically requires a slower feed rate to allow for proper teasing and distribution of the fibres, while short straw can often be processed at higher rates.
Processing capacity is often measured in bales per hour or tonnes per hour. High-capacity machines designed for long straw might handle 2-3 large square bales per hour, while those optimised for short straw could process up to 5-6 bales in the same timeframe. When evaluating straw blowers, consider your farm’s daily bedding or feeding requirements to ensure the chosen machine can meet your operational needs.
Dust suppression technologies in modern blowers
Dust control is a significant concern when operating straw blowers, particularly in enclosed spaces or environmentally sensitive areas. Modern high-performance straw blowers often incorporate sophisticated dust suppression systems to minimise airborne particles.
Advanced dust suppression technologies may include:
