I watched pops seed about 20 acres with a hand seeder, it had a burlap bag and wooden base. You'd crank the handle and walk.
It took him a long long time, but he got it done!
amazing what you can do with so little, some of my "equipment" is home made
my "culti-packer" is two 55 gallon drums welded end to end with a pipe through the middle, then filled with concrete.
Someone made it prolly 50 years ago, but it's so dang heavy it'll push sod clumps flat and push rocks down flush so your swather don't eat em
The frame looks to be off an old model T
