i feel, mr turfco bob, that you are going to get the heck bashed out of you for that comment. more than copying, we are making any machine capable of a unique type of application. you started out using that type as standard for your machine. the zsprays started out suing a boom. you made a boom as an add on as you obviously realized it pays to have the capability of both app style. so sure, we are adding another capabilty to our machines for functionality, not claiming to have a market cornered or whatever it is you obviously think you have in favor of your machine. in the end, it is about options, and you and zsprays have added them to the table. Please keep your snide comments to yourself as they are of no use here. we dont care, we dont try to ruin a thread about your machines(at least most of us, there is always jerks). so toodeloo and keep to sponsoring your company instead of being a bonifide 10 yr old in action and mentality. Thanks, a serious lawnsite user!
