Just finished it up this week. Sold my 60 gallon fimco boom sprayer for $475 and bought an old beat up 150 gallon sprayer for $250. I removed the boom for now, and made it a boomless with the teejet nozzle. Pretty much went through the entire thing. Paint, bearings, tires, piping, etc. Wish I had a before picture. Looking forward to giving it a try next summer. I think I have around $500 with everything, but it should spray 3-4x further, take the abuse much better, and allow me to keep spraying without re-filling.
I just rebuilt by fimco atv boomless too. I was going to sell it, but thinking about it now, it sure works great for small jobs. I ordered extra parts for it the last time around. I tend to drop o-rings, nozzles, etc while out in the field and can't find them. Made myself a little sprayer kit now.
