Got a ratchet rake to use on the loader on my 400. It weighs about 70 lbs and is easy to install in minutes. I tested it on a short section of my gravel driveway. With slight down pressure it loosens a lot of packed gravel. In float it levels it out the gravel nicely. I only had 20 minutes to use it and it needs a few more passes to finish up. I should be able to do the whole driveway in a couple of hours. I have some small brush and a few rocks to dig out around the property so I'll see how it does with that job. I have 1200 lbs on the rear axle and chains on the rear tires so traction is good. Anyone else using one of these on a garden tractor? If so, how do you like it?
