Bale density control system verification
For balers, pay special attention to the bale density control system. This system directly impacts the quality and consistency of bales produced. Test the hydraulic pressure in the density control system and verify that it maintains consistent pressure throughout the baling process.
Inspect the bale chamber, plunger, and knotters or wrapping mechanism for wear and proper operation. These components are subject to significant stress and wear, and their condition can greatly affect baler performance and maintenance costs.
Soil preparation implements: ploughs, cultivators, and seeders
Soil preparation equipment plays a crucial role in crop establishment and yield potential. When evaluating used ploughs, cultivators, and seeders, focus on the condition of soil-engaging components and the implement’s ability to maintain consistent working depth and seedbed quality.
For ploughs, examine the moldboards, shares, and landsides for wear and proper alignment. Check the frame for any signs of bending or cracking, particularly around pivot points and mounting brackets. Verify that depth adjustment mechanisms function smoothly and hold settings securely.
Cultivators require careful inspection of tines, sweeps, or discs for wear and damage. Ensure that spring-loaded components retain proper tension and that depth control wheels operate smoothly. For seeders, pay close attention to the condition of seed metering units, delivery tubes, and furrow openers. Test calibration systems to ensure accurate seed placement and distribution.
Remember that soil preparation implements often operate in harsh conditions, so some wear is expected. The key is to distinguish between normal wear and excessive damage that could compromise performance or require significant investment to rectify.
