TERRALAND TN

Overview of the TN_S, TN_M and TN_D product ranges.

TERRALAND TN_S
TERRALAND TN_M
TERRALAND TN_D

The TERRALAND TN_S model is the entry-level variant in the BEDNAR range of subsoilers. The machine is available with a working width of 2.5 m and can be equipped with five legs with a spacing of 47.5 cm or seven legs with a spacing of 31.5 cm. Mechanical leg protection is standard equipment. The maximum working depth is 45 cm.

The TERRALAND TN_M series includes models with a working width of 3 and 4 m, which are produced with a fixed-frame design. A characteristic feature of this product range is a maximum working depth of 55 cm. The tines are protected either mechanically with shear bolts or hydraulically.

TERRALAND TN_D represents the top product range of BEDNAR subsoilers. The “D” models excel with a maximum working depth of up to 65 cm. These machines are available with a working width of 3 and 4 m in a fixed-frame design, with the exception of the TN 4000 HD9 model, which is the only one offered with a folding design for transport. The legs are protected against overload mechanically using shear bolts or hydraulically (the TN 4000 HD9 model is equipped with hydraulic protection as standard).

NEW TERRALAND TN 4000 HD9

Working width 4 m, transport width 3 m.

The mounted TERRALAND TN 4000HD9 subsoiler is equipped with 9 legs with a spacing of 45 cm. The individual legs are fitted with hydraulic auto-reset protection. The TERRALAND TN 4000 HD9 subsoiler has a transport width of 3 m to ensure trouble-free transport on roads. The TN 4000 HD9 subsoiler can be also equipped with the rear V-RING packer.

ONE FRAME, TWO EQUIPMENT OPTIONS

TERRALAND TN both tine cultivator and professional subsoiler.

Deep loosening
Subsoiling

The TERRALAND TN subsoiler in combination with Active-Mix legs and spiked rollers is suitable for deep loosening. The special shape of the legs provides easy soil penetration, and excellent loosening and mixing effect. In one pass, the soil profile is loosened in depth and the soil surface is intensely mixed and levelled.

The TERRALAND TN frame can be equipped with special Zero-Mix legs, with a negative angle, and the heavy steel Cutpack for subsoiling without active mixing of soil. This operation is suitable for disrupting hardened soil layers, aerating the soil profile, and creating a proper soil environment.

MOUNTED PARTS

The advantage for you? A longer durability.

The individual parts of the TERRALAND TN subsoiler are mounted, not welded. The mounted parts (legs to frames, internal frames to leg beams) have a multiple-times longer durability than when those exposed parts are welded together.

DEEP LOOSENING AND SOIL CRUMBLING

Two operations in one pass save time and money.

The TERRALAND TN subsoiler consists of two rows of legs, followed by double spiked rollers. Active legs provide deep soil loosening, double spiked rollers overlap and offer an excellent crumbling effect. The advantage of the rollers is that they can be adjusted according to the required work, for example, in rocky soils.

A WIDE RANGE OF POINTS AND WINGS

Modify your machine according to your conditions.

ACTIVE-MIX legs can be equipped with points with a width of 70 mm for intense loosening, or with a width of 40 mm for demanding conditions and deep work. The wings undercut the disrupted bottom layer to eliminate clod formation. Points and wings are also available in the extremely durable LONG LIFE version (40 mm, 55 mm and 70 mm). The deeper you work, the narrower the point should be.

SIDE DEFLECTORS

Prevents visible lines from forming.

The TERRALAND TN_M and TERRALAND TN_D subsoilers can be equipped with optional side deflectors, which keep the processed material within the working width and prevent the formation of ridges between passes. Side deflectors are available in a mechanically folding version or in a more convenient version with hydraulic folding.

REAR PACKERS

Adjustable according to current conditions.

A significant advantage of the double row spiked packers is the possibility of adjusting their axial distance according to soil conditions. When working in wet soil or with a large amount of crop residues, the rear row of rollers can be moved backwards, which increases their throughput and reduces the risk of clogging. This function is part of the standard equipment of the machine.

OTHER OPTIONAL EQUIPMENT

Customise the machine to your needs.

Additional side rollers
Support wheels

Additional side rollers with points level perfectly any unevenness that may occur on the sides of the machine between two passes. Mechanically foldable. This is an excellent alternative to side deflectors.

Support wheels keep the set working depth and reduce the load on the tractor’s three-point hitch.

COMBINATION WITH FERTILISER HOPPERS

Precise fertiliser dosing thanks to BEDNAR pressurised hoppers suitable for fertiliser placement into soil profile in one pass.

COMBO SYSTEM CS
SEED BOX SB

The COMBO SYSTEM CS double-chamber pressurised hopper offers a total hopper capacity of 5,000 litres. The cart design enables placement of two types of fertiliser in one pass, or use both chambers for one fertiliser.

SEED BOX SB is a new product range of front-mounted hoppers from BEDNAR. The hopper is available in a single-chamber design with a total volume of 1,600 litres. Fertiliser is transfered pneumatically from the front hopper to the distribution head located on the subsoiler.

NEW MACHINE

Designed on a proven basis.

Although it is a new machine, the complete support frame of the TERRADUO DN and the individual structural elements (ACTIVE-MIX and ZERO-MIX legs) are based on the time-tested machines of the TERRALAND TN series. The combination has created a unique machine with a range of agronomic benefits, based on a proven foundation.

OUR INNOVATIVE TECHNOLOGIES

PROFILE FERTILISATION AND DEEP LOOSENING IN ONE PASS

The system of profile fertilisation is one of the most efficient methods to maintain a sufficiently balanced nutrient supply in soil, not only in the arable horizon, but also in deeper layers of the soil profile. This innovative method of fertiliser application connected to deep soil cultivation is not only suitable for replenishing deficit nutrients in soil to reach a balanced level of a good supply, but also to improve accessibility of nutrients to plants, and it also has a positive effect on the growth of the root system.

LONG-LIFE POINTS AND WINGS

The point and the entire abrasion area of the abrasion point are covered with plates made of sintered carbides. The front part of the wings is made of carbide plates that minimise wear and tear in the width and maintain the same shape and functionality the whole time. The LONG LIFE model offers up to ten times longer service time when compared with the standard model, ensures a consistent working depth and quality of work, improves recessing, and provides lower costs and time saved by replacing working parts.

HIGH-STRENGTH STEEL FRAME

The high robustness and durability of the TERRALAND subsoiler frame are provided by the high-strength Alform steel, thanks to which the subsoiler can process soil at a maximum working depth.

WHAT DO THE FARMERS HAVE TO SAY?

“We had the opportunity to test the TERRALAND TN subsoiler first, we had a choice of subsoiler machines and subsoiler from five different manufacturers. The quality of work convinced us, as well as the references from the neighbouring companies that use TERRALAND TN, for instance, to subsoil soil for potatoes. The subsoiler works great. Right now, we are using legs equipped with LONG LIFE carbide legs, since they have a longer service life than the standard version. They are definitely a better solution for our rocky soils.”

AGRONOMICAL GUIDE

DEEP SOIL CULTIVATION

Deep soil cultivation has its proven advantages, and it can completely replace standard tillage when carried out at the right time and in the right way. Deep cultivation enables root systems to develop, disrupts compacted layers and the plough basin, and creates optimal soil environment for proper functional water and air conditions of soil. BEDNAR machines can carry out deep loosening up to the maximum depth of 65 centimetres. It is recommended to add profile fertilisation in one pass, to provide soil with essential nutrients.
