That Equipment will work + sprayer...might be nice to find an old bed spring or chain link to drag over after seeding. Or if you want to spend a little to have a great peice of equipment get a chain harrow , a couple hundred bucks, I use mine more than anything else.
I do most of my new plot clearing right after the snow melts, you will not find a better time as everything is matted down to the ground and all your unmowable woody stems and stumps are highly visible for removal. I go after them first.
Obviously you will have a strong weed problem without spraying, if you are planning this to be an annual fall hunting plot you won't need seed in til early August, so I would mow this area after green-up, then wait a few weeks but before it grows back to height and spray it...
Then disc ALOT...you should be ready for fall.
If you plan to do a clover plot, takes a little different approach. I am finding that clover and chicory is a hard mix to beat and worth the time.
WHere is your camp? If close, i would be more than happy to share equipment and even a days work. I enjoy it, and am just plain out of blank canvas up here.
Just don't get discouraged as, It is possible to go from this to this in a short period of time…even if the spraying step is missed the first year , if you time it right. If you go with an annual it is easier in year 1.
Every year the soil gets better...personally I like to wait a year or two before making it a Perennial plot of clover,etc..
STAY AWAY from the bagged annual mixes with ryegrass, they will cause problems later.
