Picked up my new 655 tiller and some r3 tires for my 2032 Saturday. Now I have to ask, it's been very dry here in southeast lower Michigan. I need to start getting an area in my yard prepped for fall grass planting. I'm on 100% clay and its rock hard right now. Can I start by doing the first pass at 2 inchs? and keep going down? Or do i wait untill later in August? PS anyone looking for a set of r4 tires,only have 69 hours on them.
