I'm trying to decide which rake would be best for my Kubota 2920. I'm gardening and food plotting upstate NY. What about the ones with wheels? Are they necessary? I have a lot of rocks I would like to take out. I have a tiller and box scraper. Any thoughts?
If you are smoothing an area, like when spreading out loam and doing the finish grade, you need gauge wheels. With wheels, the rake follows the area that is already smoothed. Without, bumps are simply translated from the wheels to the rake.
Rock picking is best accomplished by hand. Running over the area with a rake will pop out many of them, but will also drive many back in. I'd till it, then get the wife out there picking rocks with a hoe and rake.
I can't tell you what brands are best, but I can tell you one to avoid - Bush Hog. I have a 6' BH rake and the frame design is poor - it puts too much stress on a small weld - mine cracked on both sides after a couple of uses. The frame is boxed in the middle, but transitions to U channel - the frame wants to twist at that spot, and it cracks at the transition. I had to weld reinforcement gussets in to fix it.
I like the Land pride rakes - they look really beefy, but are expensive.
