Marker device UM-11

The coupling is intended for connecting tractor hydraulic and non-hydraulic wide-cut units for preplanting soil cultivation, fallow land treatment, grain and leguminous crops seeding and other agricultural works.

The coupling can be connected with three types of SZP-3.6 sowing machines (with marker unit UM-11), two rippers KPS-4, three rippers KSh-3.6 and other trailed agricultural machines with width and traction resistance similar or close to the specified ones.

Marker device UM-11

The marker device UM-11 is designed to form a well-visible trace (furrow) parallel to the movement of the unit, which ensures the constancy of the size of the guess row spacing and the straightness of the subsequent movement of the unit.

The device SPU-11 can be used as component of a unit made of SPU-11 coupling and three sowing machines: SZP-3.6А; SZP-3.6А-01. It is purchased separately.

It is designed for use in any agro-climatic zone on all types of soil, except rocky soils.
