Soil preparation (II). Disc cultivator

We are involved in the sowing season and continuing with our series of posts on soil work. A few weeks ago we visited the New Holland Campus (Peñarubias de Pirón - Segovia), where we could work with one of our favourite implement for soil preparation, the disc cultivator.

About a year ago, New Holland signed an agreement with Maschio-Gaspardo to be able to market its disc cultivators and subsoilers under the blue brand, so now we present you our working day with this very interesting implement. It is a fascinating implement for several reasons related to efficiency work as you can see in the following features:

  • High working speed. More than 12km/h.
  • Suitable for minimum tillage tasks as well as traditional tillage.
  • Large number of hectares worked per hour.
  • Significant savings in time and therefore diesel.

New Holland has on the market two ranges of this same disc cultivator, the main features are listed below:

  • SDM
    • 520mm diameter concaved shape disc and rubber suspension.
    • 6 models: from 3 metres to 7 metres. 
    • Power requirements: from 100 hp to 320 hp.
    • Weights: from 1,665 kg to 7,360 kg.
    • Working depth: 3-10 cm.
  • SDH
    • 610mm diameter notched disc, mounted with C shaped spring.
    • 3 models: from 3 metres to 6 metres. 
    • Power requirements: from 140 hp to 360 hp.
    • Weights: from 2,460 kg to 7,420 kg.
    • Working depth: 6-12 cm.

We tested the SDM 400 disc cultivator together with a New Holland T6.180 DynamicComman tractor. Our sensations were really positive regarding handling, the tractor is well handled for both transport and tillage tasks. We could work for a few hours as you can see in our video. The most contributing factor is having a good suspension on the tractor, because this implement normally works on cereal stubble (usually hard ground) and at high speed. 

Another point in favour, doing direct sowing, is that this implement allows you to perform a superficial pass to generate better yields than direct sowing because it produces better germination of the seed.
