This paper from Bangladesh looks at blade design and rotational speed for a two wheel tractor (2WT) to establish maize by strip-tillage. PTO's, power operated tillers, that can be attached 2WTs are becoming popular in this country. They conducted experiments for 2 years on loam and clay soils. Four blades designed with varying tip angles and five levels of rotational speed were compared with commercially available C-shaped blades sold with 2WTs. Torque and power requirements for strip tillage decreased with decreasing blade tip angle and rotational speed. The best combination of blade design and rotational speed was found with a 15° blade tip angle at 320 RPM on both soil types. Machinery operators will require educational efforts to learn how to fine-tune RPM to improve crop establishment and achieve more sustainable crop establishment systems.
