That's me working the soil in the high tunnel with a broadfork--a human-powered rotatiller.
The fork is about 20" wide and has five tines, I think, to lift and aerate the soil. It worked quite well in the high tunnel, where space is tight. Really, a powered rotatiller would have been totally unnecessary. Because we haven't been trampling the soil all summer, it was still nice and light. I'd say it spent all of 15 minutes, maybe, loosening the soil in two rows.
It was HOT in the high tunnel though, even with the sides up, and I was fresh from standing outside working a golf outing all day. So I must admit that when Bill asked me if I didn't prefer that to a machine, I hestitated.
Now, in retrospect, in the cool breeze of morning, I can say that yes, the broadfork was WAY better than pushing some heavy machine into the tunnel and standing behind a hot, loud motor. It's just at 80+ degrees in a heavy weight polo and pants, just about any kind of labor seemed offensive.
That's okay. Took a super fast shower after the garden and then headed out to hear some jazz at Heritage Hill. They have a very nice 'carry-ins welcome' policy for their Monday night concerts, so I carried in some local red wine. Yes [sip]....I earned this.
