I had 2 separate sites to clear from one customer. He said his weeds were 6' tall...
Went to the first site, not so bad, no 6' weeds, how bad can it be?
Things were going well, and then this happened...
Lurking in the tall grass. The bane of mankind. There is a special punishment in the afterlife for those who toss wire and cable out into fields. Took me a half hour to get it out, since I was smart (not) enough to not bring any cutters, hacksaw or other.
Other than that, only broke one shear pin on a piece of angle iron laying in the grass.
Second site,
This stuff played heck with my radiator and coolers all afternoon. Sometimes I'd get 3 or 4 passes around, and sometimes I'd be lucky to get one, before I had to stop and blow out the radiator and coolers. Made for a very long day.
Just using my FEL and bucket to push it down and drive over it all. Sure am glad I leave them on. Saved me several times with rocks, dirt mounds, old tires, lurking in the grass.
I found the tall weeds. These were 8 feet plus, taller than the cab of my tractor, which is just over 7 feet.
Just pushing them over and mowing them down. That's a big dirt mound half way back in the center. Didn't even know it was there until I ran the bucket into it. But it's all done now.
