I do mine & 2 neighbors while hitched up. Spring & again in fall. Probably close to as much area as a football field. In spring & 1/2 that in the fall. Had it for 3 years now & it does help keep the broadleaf at bay using weed-n-feed. Really helps with over seedingSure looks like it will do the Job. And last couple life times at least!
So we have got to see pictures!!!!I had a lawn service that sprayed my yard 3-4 times one summer "PLUG AREATE" my yard one day in the fall. It looked like every dog in the county, mostly BIG dogs, had run loose in my yard and took a dump. I decided there had to be a better way!
I started gathering steel,, 1" round bar 44" long for the axle. 7 plates cut into hexangles about 7-8" across the points, 3/16" thk, bunch of 3" channel iron, about 3/16" thk, some 2" x 2" x 1/4" angle iron, and I found a 5 gallon bucket that has 2 ft lengths of 1/2" cold rolled round bar, probably 100#, I borrowed about 50#.
I styled my areator after a GLENCO Soil-Save chisel plow that I ran for a couple days every fall for several years. My plan was to semi-mount it on my #72 with my home-made sleeve hitch. I wanted to be able to lift it out of the ground to cross or turn on my concrete driveway and sidewalks. I made 7 wheels, with 6 spikes of 1/2" round bar each, used iron pipe for bearings for the wheels, 1" rd bar for axle. I had a bunch of scrap alloy cast steel shear blades that were like 3 inches thick x 18" x 10", and several smaller blades. I'd C-clamp them on the frame of the areator, my total weight is really close to the 700# that Neil's aerator is. The steel spikes extend about 3 inches beyond the plate they're welded to, with all the weight the spikes penetrate full depth, 3+ inches, the spikes actually pull a slot in the ground, I've checked and the slot on the surface of the ground is as long as it is deep. I normally aerated just before the first frost, I saw lots of holes in the ground the following spring. I aerated my 2+ acre yard every fall for 8-10 years, the health and vigor of the grass kept improving every year. And the people we bought this place from hired a lawn care company to spray and fertilize and My aerated lawn was noticably better.
There's a group on another forum that buy aerators for their brand of tractors for about what ALL 3 of my Cub Cadets are worth, they swear a plug aerator is the ONLY style worth using, a spike aerator is worthless. Even my SON is a Plug aerator Nazi. If I built a plug aerator it would be about 6 ft wide and weigh 3000-4000 pounds, maybe more, and I'd pull it with one of my FARMALL 's. I pulled my current one with my 982 first fall I had the tractor, with cat O 3-pt it worked great, I had to move the lower arm sway limiters, the aerator would swing the hitch side-to-side that the sleeve hitch on the #72 never allowed. But the aerator is 33 inches wide, #72 is 36" wide and 982 is 46" wide, I need a longer axle for two more new spike wheels total of 9 wheels, make it 49-1/2" working width, and add another 200#+/-. Probably have to add two more wider spaced wheels to carry the aerator when it's out of the ground too.
