The inter-row weeder is a fundamental tool for effective weed management and soil cultivation. Like all agricultural equipment, it requires regular maintenance and timely replacement of key components to maintain peak performance. Oliver Agro — Italian manufacturer of precision inter-row weeders — supplies original spare parts for its entire range, guaranteeing durability, efficiency and reliability.
Why Weeder Maintenance Matters
Inter-row weeders operate under constant mechanical stress: uneven terrain, stones and continuous weather exposure can compromise machine performance. Regular maintenance and timely replacement of worn parts are essential to:
- Maintain weeding effectiveness: worn rotors no longer cut weeds efficiently, increasing weed pressure and reducing crop yield
- Reduce unplanned downtime: preventive replacement costs far less than a breakdown during peak season
- Preserve precision: damaged parts compromise working precision, potentially harming crops
The Most Important Oliver Agro Spare Parts
- Rotoblizz rotors — the patented steel rotors of the Rotosark and Rotostar. They work in direct contact with the soil and wear progressively. Visual check every 50–80 working hours is recommended.
- Rotovert and Rotovert TILT-I rotors — vertical steel rotors with 3 cm curved blades. Check blade integrity and fixing bolt torque periodically.
- Colibrì discs, Rotoclean discs and Optyma 2.0 knives — specific working elements for these precision weeders. Replace when the cutting edge is significantly worn.
- Hardened flat hoes — the inter-row cutting elements of the Rotosark. Special hardening ensures long life, but periodic check of the cutting edge is essential.
- Rotobrush flexible tips — the brushes wear on abrasive soils. Regular replacement maintains effectiveness at the cotyledon stage.
- Springs and parallelograms — structural elements subject to cyclic mechanical stress. Check load springs at the start of each season.
- Anti-intrusion pins — protect rotors from stone impacts. Check more frequently on stony soils.
- Hydraulic components — seals and hoses on hydraulically-adjusted weeders. Timely replacement maintains correct machine operation.
- Bearings — essential for smooth machine movement. Worn bearings cause vibration and reduce operational efficiency.

- Full technical support: direct assistance from the manufacturer to identify the correct part
- Fast availability: minimising machine downtime
Frequently Asked Questions on Spare Parts for Oliver Agro Inter-Row Weeders
How often should Rotosark Rotoblizz rotors be replaced?
It depends on soil type and intensity of use. On standard soils, Rotoblizz rotors generally last 2–4 seasons. On stony or abrasive soils, service life is reduced. Oliver Agro recommends a visual check every 50–80 working hours and replacement when the blade profile is significantly worn.
Can I use non-original spare parts on Oliver Agro inter-row weeders?
It is possible but not recommended. Original Oliver Agro spare parts guarantee optimal performance. Generic spare parts may reduce weeding effectiveness, increase breakdown risk and void the warranty.
How do I order original Oliver Agro spare parts?
Original spare parts are ordered directly from the manufacturer or through authorised dealers. To identify the correct part, it is useful to have the machine model and, if available, the serial number. Contact us with your machine details to receive a quote.
What are the signs that inter-row weeder rotors need replacing?
Main signs: visible reduction in weeding effectiveness, increased abnormal vibration during work, visible blade deformation, excessive play in bearings. Don’t wait for complete failure — preventive replacement always costs less than a machine breakdown at peak season.
Does Oliver Agro supply spare parts for older machines?
Yes. Oliver Agro maintains spare parts availability for the entire current range and for previous models. Contact us with your machine model and year.
What are anti-intrusion pins and when should they be replaced?
Anti-intrusion pins are metal elements that protect rotors from impacts with stones and foreign objects in the soil. On stony soils check them more frequently — if deformed or broken, the rotor is exposed and wears more rapidly. Replacement is simple and quick.
