Up to a depth of 45 cm, the TERRALAND was aggregated with a 250HP MASSEY FERGUSON tractor
With a maximum depth of 65cm, the TERRALAND was aggregated with a 380HP JOHN DEERE tractor
Last summer the farming enterprise replaced their traditional plough, which was worn-out and at the end of its service life, with a chisel plough. The TERRALAND has 7 shanks with a non-stop hydraulic auto-rest system and its rigid frame allows a maximum working depth of 65cm. In comparison to competitive products, the setting of the working depth is much more convenient with the TERRALAND as it is carried out from the tractor cab via the hydraulic rear packer. The operator does not need to get out of the tractor unnecessarily and can quickly adjust the working depth as required. Details such as the working depth indicator, which is readily visible from the driver´s seat unlike those of competitive brands played an important role in the purchase. Both the machine operators and the company management are satisfied with last year´s decision to go for the BEDNAR brand.
The testing was carried out in cooperation with the farming enterprise of Probiosa.s. Kounov which farms 860ha of agricultural land. The company farms land of various soil types, from red soil to sandy soil in the area of Rakovník. The entire area is situated in the rain shadow of the Ore Mountains and is ranked one of the driest areas in the Czech Republic.
The plots of land used for the testing had never undergone deep tillage and therefore we used a digger to make open soil probes to a depth of 120cm. It was clear at first sight that in such conditions it would not be an easy job for the parts that are subject to wear. All areas where the testing took place had been ploughed in a traditional way up to a depth of 20–25cm for many years. Over the years, massive impenetrable layers were formed. Deep tillage of soil was preceded by stubble tillage with the 12cm SWIFTERDISC XE 10000 disc cultivator which Probios acquired for this season. The measurements showed that the loosened plough layer was 12cm thick thanks to the stubble tillage, while the settled plough layer was 8cm thick. Extreme compaction started at 20cm under the surface and continued as far as 60cm in depth. The subsoil started at a depth of 80cm under the surface and it was not compacted to an excessive degree.
The photograph and description of the soil probe say it all
The first row of three shanks on the TERRALAND TN 3000 HD7R chisel plough were fitted as follows: behind the tractor wheels the 70mm LONG LIFE chisel with LONG LIFE wings and 70mm wide chisel with weld deposits and standard wings. The middle shank was fitted with a standard 70mm wide chisel and with standard wings. The second row of shanks was not used for the testing.

Soil tillage up to a depth of 45cm was carried out at the end of July and in the month of August. In October and November, the plots of land were processed to be ready for winter up to the maximum depth of the chisel plough, i.e. 65cm, so that any water during the spring thaw would be absorbed into the soil to minimize surface drainage. During the testing, all the spare parts subject to wear worked in the same conditions.
These are working sections which do not feature any cemented carbide coating. In such harsh conditions, they were subject to most wear. The chisels had to be replaced for the first time as early as 7.3ha. For the test to be as accurate as possible, several chisels were employed. After 250 hectares, the replacement interval settled at 15ha on average. The front part of the regular wings is not made of sintered carbides and that is why they soon lost their shape. They were replaced after 53ha on average.
It is very similar to the LONG-LIFE chisel; the chisel tip is made of cemented carbide. The abrasion surface and sides of the chisel are protected by the weld deposits and the entire chisel is reinforced. The chisel had to be replaced for the first time after 140 hectares. A weak point of this chisel is the fact that it wears down unevenly.
The tip and the entire abrasion area of the abrasion chisel are covered with plates made of sintered carbides. The front part of the wings is made of carbide plates that minimize wear and tear in the width and maintain the same shape and functionality the whole time. The entire test was conducted on 250 hectares of agricultural land and the working sections did not need to be replaced at all during that time.

In the conditions of the Rakovník area, where we tested the wear and tear, the testing revealed that the LONG-LIFE chisel lasts up to 17 times longer than the basic chisel and twice as long as a chisel with weld deposits. LONG-LIFE wings last five times longer than regular wings without weld deposits. After approx. 250ha, the LONG-LIFE chisel is in such top condition that the operator estimates that it will be able to work at least another 200 hectares next season. This will support the investment profitability even more as the profitability is not expressed merely by the number of the hectares covered and the financial costs, but also by the time savings in connection with the chisel replacement as well as with ordering, transporting and collection from each farming enterprise warehouse. It is certainly worth paying a little bit extra for better quality, especially if it leads to an increased quality of work and significant money savings.
