HI, I have the possibility of getting a rather large mowing contract....unfortunately the same peoperty also has massive amounts of weedeating..... I spoke w/ the owner and they said they absoultely did not want us to use any sprays on the property (no use of Embark or ****** griwth suppressors here)... My question is, what is the best way to take care of massive amounts of weedeating with out killing yourself or having to hire a bunch of people to weedeat.....I have tried to use the factory support strap for my weedeater but it doesn't seem to help the arms alot because the property has alot of varied terrain and it ends up you have to carry the weedeater more than the strap does (if everything was fairly level the strap could be used to support the weight alot but the ups and downs and the need to get the weedeater under trees and bushes negate the straps effectiveness and hinders the motion of the weedeater too much....I thought of using the DR wheeled string trimmer on wheels but the hills would kill you pushing that thing around......I think somebody told me of a backpack weedeater ? (engine etc on your back so only weight you carry w/ your arms is the shaft and the trimmer head)......Any other ideas would be greatly appreciated (I currently use a Shindaiwa T-270).....I have a 230 that is lighter but not as much power for the thicker stuff). .... Thanks for your help.
