1. INTRODUCTION
Intended use
POTILA MASTER 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 jukka POTILA MASTER 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 MASTER seedbed cultivators are available with a wide range of optional
equipment to ensure optimal granular structure and level soil surface.
