i have a odd need , the problem is weeds and grass, in town, growing in a subdivision i do the maintenance for, the more i spray them with round up, and spetricide,and other 'weed killers' ect, the better they seem to grow, lol ,these weeds all grow in the crack between the cement curb, and the pavement which varies from none at all to 2 inches in width and varies in depth, since walking all the roads in the subdivision, [ about a mile and 3/4ths worth] is out of the question, as i physically cant walk that far, my idea is to find a arbor, like for a belt driven saw ect mount it on the mower deck of my farmall cub, offsetting it to the right of the deck,then add 1 or 2 wire wheels to it and power it from the belt pulley on the cub, im choosing the cub as its first gear is the slowest of my tractors, this would give me hydraulic up and down via the deck,as well as a great view of the work being done, and i dont have to look behind me to see what its doing. i would be carefull with the mounting, as the cub is also needed to mow, this arrangement would supposedly allow me to drive along the crack and 'grind' the weeds out, now my ideas like this have been known to be a complete failure in the past, and this just has all the smackings of another one, so im in here with it to get feedback, also find out what would really do this job, since all the cracks are not the same size or depth and the asphalt has varied edges, any kind of a rigid ripper type device wont work, [ hate to admit it, but i did try that]
