How to recognize side knife wear for rapeseed and when to replace them? | GĄSKA
The harvest season is a time of intense work and pressure – every hour of downtime means real losses. The key to efficient rapeseed harvesting are properly working side knives – components that are often underestimated, yet have a huge impact on the quality and efficiency of the combine harvester’s performance. Their wear can surprise even experienced farmers, leading to serious problems during harvesting.
In this article, prepared by GĄSKA – a trusted supplier of agricultural machinery parts – we will explain how to recognize signs of side knife wear for rapeseed, when it is worth replacing them, and what to pay attention to when choosing new cutting elements for headers.
Understanding the role of side knives – why are they so important in rapeseed harvesting?
Rapeseed side knives are specialized components mounted on the sides of combine headers. Their task is to effectively cut rapeseed stems, which tend to wrap around machine parts and hinder harvesting. They work in parallel with the main cutting unit, increasing precision and reducing losses.
In field conditions, rapeseed can be difficult to harvest – its dense and flexible stems can block feeders, clog headers, and cause downtime. Worn or improperly selected side knives are unable to effectively counter these problems, which may lead to blockages, machine damage, or even loss of part of the yield.
Key advantages of investing in quality – what you gain with GĄSKA
