1. INTRODUCTION
Intended use
POTILA MAGNUM PLUS seedbed cultivators are intended for preparing seedbed in
either the spring or fall. The field can be ploughed or cultivated, and it can contain
straw or other plant parts. The seedbed cultivator is used for loosening and crumbling
the soil after primary tillage to produce a level seedbed and well-crumbled topsoil.
The seedbed cultivator is NOT intended for primary tillage of untilled soil!
The open frame structure of POTILA MAGNUM PLUS seedbed cultivators enables
tine spacing that allows unrestricted, high-flow of soil. Level seedbed even on soft
soil types is ensured by the tines that keep their working depth, accurate working
depth control and large, high-capacity wheels.
POTILA MAGNUM PLUS seedbed cultivators are available with a wide range of
optional equipment to ensure optimal granular structure and level soil surface.
