Scott Wahlin, CGCS said: Ransomes looked at buying an aerifier called a Weideman many years ago. We had it at the test facility on Longboat. We did over 150 acres with it in deep tine mode and punched holes in a lot of rocks. I don't know whatever happened to them, but that thing was bullet proof.
The company still exists and makes amazing equipment!
http://www.wiedenmannusa.com/Had their deeptine machine at a previous course, would rip old cast iron pipe out of fairways and not miss a beat!!
We are coming up on time to replace our Vertidrain, I'm recommending Wiedenmann!!
We currently have their Super 500 (sweeper/ flail mower / verticutter) and it's the most versatile piece of equipment we have!!
All that said, the Toro ProCore 648 is hard to beat for greens and tees!!
