the only problem with stuff like that is the cost especially if your not doing this type of work full time. spending $2k+ to make $400 doesn't make sense. it is part of why i usually use a mower. mowers are cheap compared and it is pretty easy to recover the cost of a cheap mower. i usually get my mowers for free so other than fuel used it is usually mostly profit.That's a job my Swisher Rough cut would eat up in less than an hour. It is the way to go for high grass and weeds. It is a true rotary cutter with 2 swinging blades and a stump jumper and will also chop down up to 2" saplings.
