Harrow needle Hydroficated BIG -15 (Big 21) production SibzavodAgro
belongs to a class of heavy , with wide , universal harrows.
Universal harrow is designed for spring surface loosening fields
coated stubble , ... at a depth of 4 to 6 cm in order to maintain moisture in the soil; seeding weeds
and volunteer grain crop stubble without significant disruption ; alignment
field of surface pretreatment and for harrowing winter crops
maize and perennial grasses .
When driving harrow the field covered with stubble , needle wheels and roll
deepened into the soil under the action of its own weight . Needle loosen the topsoil and
both are buried weed seeds and volunteer grain crops. Thus up to 75 %
stubble remains on the surface of the field. When operating at higher speeds harrows (up to 12 km / h )
angle of attack of the battery is reduced . The angle of attack can be set to 0 ; 2 ; 8 ; 12 and 16 .
The original design of the heavy harrow allows you to easily and quickly transfer it from
working to transport position and back again without disassembly . Operation harrows to prepare
work or transport takes less than five minutes , and can be performed by one
man. This advantage distinguishes harrow "Demetra" from other instruments
conventional designs .
Simple and rapid adjustment of the angle of attack of the teeth allows a wide range of
possible options depending on the field conditions and the type of work .
Heavy , Wide- universal , needle harrow combines successful
structure , size and optimum performance characteristics guaranteed
reliability.
Advantages of needle harrows BIG -15 (Big 21) "Demetra"
BIG -15 and Big 21 - a new category harrows designed for efficient operation
with crop residues , seedbed preparation and other farming operations in
any cropping system - the "traditional" , "minimal" or "zero" .
The long lifetime of working bodies , needle drive - hoe made
of high-strength wear-resistant steel 110G13L -2 .
The same provision for the replacement of sections of workers and get
one basis following tillage equipment :
Harrow "Demetra" BSP -15, the BSP -21 (heavy prozhinaya )
Lushchilnik LDH -15M , LDH -21
A large number of tasks , including separately can be identified:
mulching , weeding in the stage of white thread , mulching , distribution
crop residues .
High maneuverability harrow in the transport and working position , the possibility of
maneuver backwards in the transport position , as well as a quick translation harrow working
position and back to rapidly intervene in unpredictable
weather conditions.
Transport width and height harrows allow to transport it along the roads
General purpose without necessarily attract traffic police patrol .
