I spray barricade out the same time I spray herbicide I don't any problems spraying barricade.. I spray it out at 1gal per k.. I know some guys on here spray at .5gal per k..
I would suggest you go look at all of the ride on's you can.. if you have to drive 3hr I would so you can atleast look at them.. I have a 36 jr had it since 07.. from what I see the ground logic is a good unit.. before I got my z spray I went and looked at the pg then the z spray in person the pg did not impress me at all...the z spray in my opinion is built a lot better then the pg don't know what the price difference is now..
The Internet lets you be anything you wannabe except smart. Your stupidity will always come out.
