No doubt they are a hoot to run...they are eye catching too. I mow about 150 yards of roadside ditchbank along the edge of our property, that takes me a few passes. It has backtop road on one side, and there is a township bike path between the ditch and my woodlot, which is why I like to keep it up. I stop and shut it down when bikes or pedestrians pass, and get a lot of strange looks with that menacing thing hanging off some 'antique' tractor. The road turns to gravel beyond me, and is a thoroughfare for the local farmers to get in and out of town, so I've had a couple of them stop to chat when seeing it in action as well.
But....we will have to find you a Weedcutter too. I tell folks it's like snowblowing, except when the weather is nice. You cover a lot of ground pretty quickly, but it's a poor choice for ditches and under low hanging obstacles, where the sickle excels.
