Top-of-the-range compact disc harrows
With outstanding quality of work and sophisticated modern design, the TerraDiscPro Hydro is the premium compact disc harrow on the market. The hydraulic folding mechanism of the TerraDiscPro Hydro is designed with two large-scale cylinders while the necessary safety is provided by a mechanical locking mechanism with automatic hydraulic unlocking prior to folding. The optional folding chassis transfers additional weight on the discs, the TerraDiscPro is therefore particularly stable in the ground.
Advantages TerraDiscPro Hydro:
- The robust design ensures safety in professional use in all conditions
- Exceptional throughput thanks to the high frame and clearances between discs and disc supports
- Excellent handling with simple and central working depth adjustment (optionally hydraulically adjustable)
- Mechanical transport locks with automatic hydraulic unlocking
- An optional retrofitted folding chassis provides added weight to the wheels, exact depth control and superior maneuverability
Advanced Technology
Toothed mulch-discs
The ideal dimensions of 510 mm diameter, as well as the special concave form of the discs, combined with the new intrusion angle ensure excellent penetration. This makes it possible to work in heavy and hard soils. Additionally, the good penetration enables higher working speeds, because the machine stays firm on the ground. The roughly rigged form supports this effect, and grants effective crumbling and optimal sprouting conditions.
Flexible disc suspension
The installation of the rubber bushings on the discs ensures maintenance freedom and maximum operational reliability. These spring elements provide excellent soil adaptation with low-depth work and allow work on uneven ground or roadways. In addition, these rubber elements provide effective protection against overload on rocky soils.
Effective working width - foldable edge discs
The nominal working width is achieved by the overlap of only one disc; this prevents partially worked strips at the edge of the field. The new spring-loaded edge discs can be folded fast and effortlessly, ensuring a width of less than 3.00 m for the device or 3.50/4.00 m (rigid devices) for secure road transport.
Disc bearings
The new TerraDiscpro is equipped with high-quality SKF-bearings only. The two-rowed maintenance-free corner bearings are tripple-sealed and continuously greased, so moisture and dirt don´t stand a chance. The screwed attachment of the bearing shaft to the disc holder greatly improves maintenance convenience immensely and avoids unnecessary repair costs.
Edge plates (optional)
The edge plates can, in certain situations, prevent ridges by the outer discs, thus ensuring a perfect connection between the different working widths. As with the edge discs, the edge plates are fast and effortlessly foldable and ensure a transport width of less than 3,00 m alternatively 3,50 / 4,00 m (fixed machines).
Working depth adjustment
The mechanical adjustment of the working depth is very comfortable and precise from the rear of the device with a central adjustment element with depth gauges that can be folded in and out. It is also possible to opt for hydraulic depth adjustment (for TerraDiscPro TR series with memory cylinder) which allows the operating depth to be adjusted over the whole range during operation, which is very advantageous, e.g. for temporary changes in depth for complete operation of ruts.
Rollers
Toothed packer roller
Ø 520 mm - Ø 600 mm
• Good all-round features
• Particularly clog-resistant, thanks to scraper
• Tough in stony conditions
• Excellent ground drive with individually welded teeth
Open roller
Ø 520 mm
• Weight advantage: high bearing capacity on light to medium-heavy soils (10 rods)
• Arrangement of supporting V-bars (from 2 m) in order to avoid soil erosion and tension on the sides
Solpak I ring roller
Ø 600 mm
• Ensures perfect leveling, compresses and closes soil
• The runners between the rings are height-adjustable, thus supporting the consolidation intensity. They also offer reliable cleaning of the rollers
• Particularly suitable for subsequent mulch sowing
Solpak II ring roller
Ø 600 mm
• Perfect work results with outstanding reconsolidation, crumbling and levelling
• Better ground drive in light conditions
• Greater stability with continuous central pipe and 5 spokes
• Improved ease of adjusting the scraper bar thanks to adjustment of only 1 spindle
Packer roller
Ø 800 mm
• High load capacity in light soils, the roller does not "sink"
• Very good ground drive thanks to angular shoulder profile, high degree of operational reliability
• Reconsolidation in distinct strips
• Highly suitable for subsequent mulch sowing
• No risk of blockages by stones
KTW roller
Ø 660 mm
• High loading capacity in light soils
• Good ground drive also in light and sandy grounds
• Tough in stony conditions
• High consolidation
• Grooved consolidation, highly suitable for subsequent mulch sowing
Tandem ring roller
Ø 600/600 mm
• Particularly viable in light, sandy soil
• Flat profiled discs arranged in 2 rows
• Excellent ground drive with individually welded driving plates
• Can be combined with TerraDiscPro with semi-trailed chassis
• Tracking tine (optional) for perfect levelling
Double open roller
Ø 520/440 mm
• Good leveling and very high load bearing capacity in heavy duty applications in light soil
• Arrangement of supporting V-bars (starting from 2 m) in order to avoid soil erosion and tension to the sides

Harrow tines
Harrow tine in front of roller (optional)
The harrow tine which is located between the discs and the roller, guides the soil/straw mass away from the roller and downwards, thus ensuring perfect straw distribution. Recommended for open rollers like the SolPak-rollers.
Harrow tine behind roller (optional)
All rollers are also available with a harrow tine behind. With 12 mm thick tines, which are adjustable in tilting and height, the harrow ensures optimal alignment of the straw, and prevents quick growth of weeds. (Not available for TerraDiscPro TR models)
