I am currently running an old FMC 400 gallon Economist. Will be upgrading possibly next year to a 400 gallon Turbo-Mist. I've actually considered going to a 2 row sprayer but that is because in my area the rain can come in fast and often so we have short spray windows and I need to cover as much ground as I can as fast as possible. That is why I won't use anything less then 400 gallons. You spend too much time filling the sprayer. I put 100 gallons of water on per acre so I cover 4 acres between refilling. It works good too because most of my blocks that are further away from my filling area are all 3-3.5 acre blocks so I can fill up, spray the entire block then run the tank out on the larger block before refilling then repeat.
What other equipment are you wanting to know about? I have a 1 ton Vicon mounted on a cart for banding fertilizer, I have a Green Hoe Company weed spray bar that I mount on the front of one of my tractors that is currently plumbed into a 3pt 60 gallon sprayer for weeds (I am working on a twin tank trailer for weed spraying so I can spray row middles with one spray and under the canopy with a different spray). I use a Bush Hog 295 rotary cutter for chopping the trimmings, an old Massey Ferguson 3pt auger for large end posts and a Shaver post pounder mounted to the middle of my Farmall for replacing broken posts. Out side of that anything else is usually custom made unless your going big with mechanical harvesting.
Tractor wise for the vineyard I run a Ford 1920, Case-IH Farmall 45A and a Kubota M8540 Narrow.
