Wheel hoes are excellent! I started using one last season, though I’d been reading about them for a while—what took me so long?! They cut major time from straight cultivating, weeding between-row and paths where you’d usually use some type of hand hoe. Mine is from Valley Oak, and I’m absolutely happy with it. I use the standard 8″ blade, and that’s it. I haven’t tried the Glaser wheel hoes, but they’re no doubt fine as well. They come with a five implement attachments, including blades in various widths, a hiller/furrower, and a 3-tine cultivator. There’s a two-wheel/two-blade attachment for the heavier pro model that allows straddling a row. The handles can be offset for working from the side.
The three models of wheel hoe are No. 500 (the Berg), 600, and 700.
