Grass subsoiler

[Extreme Optimist]

Been looking at getting a grassland subsoiler in and wanted to get folks thoughts.
From what I've seen the Erth looks to give the best results but God the price, the browns unit looks pretty much the same at a vastly better price.
We're on really heavy clay and hp is limited and I've noticed widely varying claims from manufacturers about what hp needed to pull their machines.

Beware of the Browns, they take some grunt to pull!! I bought one on the back of the brochure saying you needed 70 - 90hp (I had 112). It was a 3 leg machine and I could barely move with it, no matter what adjustments the dealer and I made. Eventually rang the contractors and they came down with a 200 hp John Deere......wouldn't touch it. They eventually came down with a 939!!!

Can pull a 5 leg 3m Shakearator here with 80 hp, it's light land but prone to compaction. you need the vibrator on mind, pull the pto clutch on and the tractor stops.

Our 4 leg erth is pulled very easily by a 150 four cylinder Deere through some pretty heavy clay.

I had a demo of the Erth 4 legger and I pulled it through the same ground with my 112 hp lightweight Fendt that had the wheels spinning on the 939. In anything but sand, I would have doubts about the Browns which is a shame as it is very competitive and probably with a few design tweaks would do a decent job.

Erth 4 leg here pulled in most conditions by a 6030 elite Nh with v little bother doing a first rate job

Pulling our 4 leg Sumo with Fendt 415 no bother at all unless ground is extremely tight.
