FIELD tests were used to evaluate a PTO driven
powered disk tiller. This research was carried out as a
joint project between Mie University and Michigan State
University. The American field tests focused on tillage
performance to explore application of the implement
under Michigan field conditions. The powered disk tiller
has good ability to cut through crop residue and weeds
compared with an unpowered disk implement. It also
has increased soil pulverization and improved soil
penetration ability compared with an unpowered disk
implement. The Japanese field tests focused on
measurement of draft and power requirements. The
draft and power requirements were influenced by ground
speed, PTO rpm, tillage depth and soil conditions.
