Power harrow drill combinations continue to sell strongly into the UK with wider folding units, such as Lemken 4.0 to 6.0m Zirkon 12 and Solitair 9 units, now outselling its rigid 3.0m models. This also means demand for used wider units has increased, but you need to tread carefully to secure a sound example
At a glance, you will be hard pressed to tell the difference between a 2004 Zirkon 10 and Solitair 9 power harrow combination drill and a current Zirkon 12 and Solitair 9. In terms of their ability to establish a crop, both older and more recent models will do pretty much the same job too. Which will possibly suggest an older combination in good condition will be equally as good a buy as a more recent model that has done more work.
