@Greythundercloudys Sumo disturbs the ground less.
The differance it leaves is quiet marked. They more increases the water percolation through root mat and livestock compaction. Think how quickly heavy rainfall drains and time roots spend in a shallower than ideal soil profile.
As to drainage - it makes a tremendous difference. We have some fields here that were soaking all year round until we ran the Erth through them. We once spread dirty water/slurry on a field (as normal) that had been gone over with the Erth panbuster earlier in the Autumn. Within hours we had dirty water emerging from drains - not damaged, ust that the water could reach them so much more eaily
Hire a sumo here now and then. Does a great job but timing is the key, dryer the better to get the shattering effect. First time we used it had a field on heavy clay that just sat in water, could hardly drive across with the bike all winter. The next year you could drive around with the tractor after an inch of rain and not leave a mark! that field is about ready to do again but it will be 5 years since it was done. Power isn’t so much the issue but you need a good size tractor on the front as the sumo is a chunk of weight. Plenty weight on the front especially if the ground is hard to get some traction.
