TIREX 9 Spring Tine Harrow with Knife Roller
The TIREX 9 spring tine harrow with knife roller is a trailed implement manufactured by Avers-Agro for working crop residues and the topsoil. The implement is designed to chop and distribute sunflower, maize, rapeseed and cereal crop residues, level the field surface and provide a partial residue mulch.
The combination of knife rollers and a spring tine harrow works on crop residues and the soil surface in one pass. It is also used to help conserve topsoil moisture and control weeds at the white-thread stage.
Working width: 9 m; working speed: 12 km/h; field capacity: 10.2 ha/h. Shallow working depth: up to 5 cm. Transport width of both configurations: 2.5 m.
Applications of the TIREX 9 spring tine harrow with knife roller
Chopping stalks and crop residues
Distributing crop residues across the field surface
Levelling the field surface
Providing a partial residue mulch
Helping conserve topsoil moisture
Controlling weeds at the white-thread stage

Actual field capacity depends on field layout, the number of headland turns, soil conditions and crop residues. The 9 m working width and the 9.6 m overall width in working position are different measurements.
How the TIREX 9 spring tine harrow with knife roller works
Knife rollers chop crop residues
The rollers are fitted with flat blades. As the implement moves, the rollers rotate and chop stalks and other crop residues. The open-frame design leaves space inside the working elements for plant material to pass through.
Chopping results depend on the crop, stalk thickness and moisture, blade condition and implement settings.
The spring tine harrow distributes residues and levels the surface
The spring tines work on plant material and the soil surface. They help distribute residues, level the field and control weeds at the white-thread stage. The spring wire diameter is 14 mm.
Mechanical tine angle adjustment
The spring tine harrow angle is adjusted mechanically. The same setting is applied across the sections to suit working conditions. Changing the tine position adjusts the intensity of contact with the field surface.

Partial mulching and moisture conservation
Chopped crop residues remain on the field surface and form a partial mulch. This helps limit moisture evaporation and protect the soil surface from wind erosion. Coverage depends on the amount and distribution of residues.
Field photos before and after TIREX
The photos compare tall sunflower stubble with the surface after the implement has passed. They show the condition of the crop residues and field surface under the conditions recorded during filming.
Folding and transport
Hydraulic cylinders move the frame between working and transport positions, with the sections securely locked. In transport position, both configurations have a length of 6.5 m, a width of 2.5 m and a height of 3.45 m.
Maximum transport speed: 20 km/h. Check that the sections and transport components are secured before moving the implement.
Frequently asked questions about the TIREX 9 spring tine harrow with knife roller
How does the TIREX 9 spring tine harrow with knife roller differ from a conventional roller chopper?
The TIREX 9 spring tine harrow with knife roller combines spring tines and knife rollers. The blades chop residues, while the tines help distribute them, level the surface and work the topsoil.
How do the L90.470W and L90.550W configurations differ?
Both configurations have a 9 m working width. The L90.470W has 470 mm rollers and weighs 4700 kg; the L90.550W has 550 mm rollers and weighs 5100 kg.
Can it work after sunflower and maize?
Yes. TIREX is designed to chop and distribute sunflower, maize, rapeseed and cereal crop residues.
What is the working depth of TIREX?
Shallow working depth is up to 5 cm. Adjust the spring tine harrow angle to suit the soil and crop residue conditions.
What are the transport dimensions?
Transport dimensions for both configurations: length 6.5 m, width 2.5 m, height 3.45 m.
What information is needed to select a configuration?
Tractor model, main crops, approximate quantity and condition of crop residues, field area and main cultivation tasks.
What tractor is required for the TIREX 9 spring tine harrow?
The TIREX 9 spring tine harrow with knife roller requires a tractor with power from 160 hp When selecting a tractor, consider soil conditions, the amount of crop residues, working speed, hitch compatibility and the hydraulic system.
