any thing you planty is better than not planting it LOL
in the woods is very hard, for several reason, once green up, leaves prevent a TON of light to alloow things to grow, then all them leaves both on the ground NOW and come fall, they make a lot of acid to the soil, making a bunch of lime needed to make things grow
they do hjave some seed blends that will work better in shady spots, but most ate HYPE on a bag LOL all seeds need sunlight tyo grow and strive, just as a good soil with food in it for them
as for finding a spring harrow, My best advice is drive about farm areas with cash in the pocket, and look for rusty lawn items LOL
odds are you will find several faster than youi think, and hey, 20-50 bucks in gas will more likely save you money than going to an auction, folks at auctions know deer hunters are suckers for smaller food plot things, look at tractor prices, they more than double in the past 10-12 yrs doe to how popular foot plots and hunters have become
so, looking on farms will save you money IF you have the time, as we all know time is money in a way!
like I said, IF you were closer, I have 3 of them now two singles for atv's and a big one for behind the tractor, and I know here about 25 opf them are on farms in my area! LOL
BUT what you would spend in gas to get here you'd loose money! HAHA!
don't forget, many places rent out equipment, and some times thats a better rioute too than buying and storing
and up keeping
from a walk behind tiller, or a 4x4 tractor/tiller/front end loader!
in wooded area's I think creating good mineral sites might be a better idea than food plots, as that sunlight gets loweer as the yr goes on and most die out before hunting season LOL
where a good mineral lick might get action all yr!
good luck
