The OTMA tiller is a double coil spring-loaded tine which is fitted with a reversible
chisel point. The spring-loaded action allows one to work in rocky and harder soil
conditions. Ideal for aerating grass pastures and loosening soil up to 200mm deep.
The OTMA tiller can also be used to cultivate weeds and make seedbeds. When
tines encounter obstructions under the ground the tine will disengage and reengage
once it has passed over the obstruction.
