Three words for you boys: Electric lawn mower.
Turn the bitch upside down, get a replacement grate for a square BBQ grill, hit the corners with a weld (or strapping or conduit tape and some screws) and you've got a trimmer with some serious power for $150.
PLENTY of suction, relatively cheap, easy to remove blade for sharpening/cleaning.
Just seems like a no brainer. If suction, availability, and cost are your concerns, I think this route is better than modding out a garden groomer to make a half-assed trimmer with no suction when it's only going to save you maybe $50 and you'll end up spending 15min of out every trimming hour cleaning up and unclogging the thing because it has no suction.
Wow, nice idea! This is definitely a great idea folks! K+ bro!
Sounds way to small and weak weak..I have an Army surplus jet engine that I have been welding man hole covers over for the trim screen.
A man sized trimmer for my micro grow
