I've got a couple ProLawn sprayers for sale.. www.prolawnsprayshields.com I have the 11 ft ZTR mount sprayer and the 52 inch walk behind.. I baught the 11ft used, but in excellent condition.. I've put around 100 hours on it.. I've changed out the spray nozzels, and put all new skirts on it.. the tank has some light staining.. but otherwise the whole rig looks great. I have added the spray wand to the ZTR model.. If you've never used one of these, they're great.. I use mine on a Grasshopper 721D, however I've heard that It will attach to nearly any ZTR.. It can spray in ANY wind conditions.. Applys chemical extremely evenly thru fan tips, and I've used it with fungicides, Ferts, Pre-Ms, Weed Killers, etc ALL with excellent results. It has jet agitation, a 40 gallon tank and a killer manifold system. I've used it on 3000 sq ft lawns, and on 8 acre + monsters.. The wings fold up one at a time, so you can spray as little as 52 inches at a time, or as much as 11 feet. I run it at around 25 psi and get 2 acres out of one fill.. I've been told that I can do up to 4 with one fill, but have never had the need. I love this, and I WILL be buying another. My tax deduction has ran out on this one. The reason I've only used it an estimated 100 or so hours is because I make my employees use a hose end sprayer, and I was the only one who used this.. mostly on warranty, or special jobs that I didn't want to entrust an employee to. I also have the walk behind 52 inch model.. 25 gal capacity I think, and 12 v pump.. (STRONG) I didn't use it much at all.. maybe 3 lawns. I discovered that once I had the spray wand on the larger model, I no longer needed this for my back lawns etc.. so It's sat in the garage, and likely needs a new battery. The large ZTR model is probably around $5,000 retail after the wand add on.. and the walk behind is around $2,000 retail.. They pay for themselves VERY quickly. I need $ 3750.00 out of the ZTR sprayer I need $ $1,500 out of the walk behind... check out the web site.. www.prolawnsprayshields.com also, there's a video of the unit in action on grass hoppers web site.. Feel free to get ahold of me any way you can if you're interested..
