We (our hunting gang) just recently purchased a grey market RS2005 tiller to till up some ground for a food plot. The tractor that was used is a Kubota, about 50hp (sorry, I don't have a model number for you). They tried it out but the tiller just wouldn't touch the new ground. Now, this field hasn't been farmed for at least 20 years but there is no clay and the conditions were very damp. What would you recommend in regards to tractor speed, pto speed, etc. We're hoping our purchase wasn't a waste of $$$!! Your advice is greatly appreciated!!
