Harrow spring BP-9, Kiev region.

SPRING Harrow - BP-9 - "HEAVY HARROW" - "NN-9"

The five-row medium spring harrow of the "HEAVY HARROW" model is equipped with a rigid frame structure and teeth with a diameter of 10 mm with a distance between the teeth at the output of 2.5 cm.

The use of an average spring harrow provides a wide range of agrotechnical operations:
• winter combing;
• early spring closing of moisture;
• zadelki mineral fertilizers and herbicides;
•tillage of the soil with the purpose of leveling the field surface;
• ensures the process of self-cleaning from the earth and plant residues;
• destruction of weeds in the initial stage of development in the "white thread" phase;
• pre-emergence and post-emergence harrowing (thanks to it, manual weeding and the use of herbicides can be dispensed with).

The working bodies of the harrow are special springs. Which by the impact of vibration on the soil perform high-quality crumbling of the soil and exclude its clogging. The angle of attack is regulated mechanically by moving the segment on the movable element.
It is economically proven that when processingsunflowers on 500 hectares of land, a BP-9 spring harrow pays for itself per season (fuel consumption 1.5 l/ha + costs for applying andpurchasing herbicides).(//tractor-service.com)
