The Iseki Unclemole was state of the art, in the 1980's. Now it is archaic. I have used Iseki, Soltau, and Akkerman. Iseki is good in certain ground conditions. The simplicity of it's control system is a plus on short drives in soft ground. In hard cohesive soils the Iseki is painfully slow. In glacial till with boulders, a Soltau was best. In hard rock the Akkerman was best, in my opinion. I am out of the business now, retired, but in some respects I miss it.
