HAd too much stuff at the house and sold mine. Probably no better basic implement to level soil or pluck rocks out of a foodplot.
Easy on small tractors and ATV's.
Use 3 pieces of chain to make a tow rig. LEft, center, and right. Otherwise it tends to hop / crawl from left to right.
Tall grasses do plug them up. However, mow high, then mow low before using. That old dead grass is good mulch and future fertilizer, try keep it in the field. Use your feet to push them back between the tine if plugged. Using a pry bar is helpful too. Wdeg them back and put the bar in the side to help lift up. A 3 point version is a ton easier to clean.
I really wonder why these are not made anymore.
Bought a nice big 4ft single row ATV disc and pretty much made all my foodplot in the forseeable future. Great tool for making new plots.
