To OP - My spouse and I farm a 5 acre vineyard with the idea to expand to 10 acres out of a 42 acre site. We are spaced 7' by 4'(double Guyot) and 7' by 3'(single Guyot). We have a ~50hp Landini Mistral 16spd(of which 4 creeper), MFWD, open station, 3SCVs, and it's non-hydro which we purchased for $12.5K with 375hrs on it. It's been a great little tractor with a bigger capability compared to many others in this class. That said it rides a bit high to deal with side hills comfortably. If you're thinking wide rows there are many stable choices in tractors out there. One you might consider is a used Landini Rex in the lower ride height, Ithink they call it a GS configuration. It's heavier than my Mistral and can lift more in the rear. Downside of low tractors is they don't lift as high from the ground up. Such as if you need to use a post hole auger it might not clear it from the ground. As far as sprayers go the CIMA is a fine sprayer and many near me have that one. I'm working my way up to a tilting recovery panel sprayer that will work one row at a time from both sides. With slight side hills on narrow rows the sprayer nozzles/tips on conventional one side two row sprayers without tilt do not get parallel to the spray surface. With the CIMA I think you have good control of spray to canopy distance and height. My preference on sprayers would be to tow it and not carry it. For our 5 acre vineyard in early season I probably use 40-75gallons of spray mixture. Late in the season like now I use 140-150gal which is a reload for me with our 100gal PakTank. One thing with respect to spraying if you can plant similar(harvest timing wise) varieties near each other then you can spray similar chemicals in blocks. For instance right now I am close to harvest for auxerrois and chardonnay and have to use chemicals with short PHI whereas for my chenin blanc, cabernet sauvignon, cabernet franc, and barbera are much later so I may use different fungicides with longer PHIs. One other point with using only one vineyard tractor, like I do, one needs to be prepared to get it fixed and back up and running in short order. I have a smaller Deere 455 garden tractor that mows the alleys, spools out bird side netting, carries tools and supplies anywhere in the vineyard. I also have a Deere 5325 with loader and backhoe that I use to unload deliveries and take care of heavier property maintenance tasks. We plan to get a second vineyard tractor next year and most like a used electric golf cart to quickly run tasks in the vineyard. Good luck with your endeavor. If you have questions fire away but be forewarned that the season is getting super busy right now and my response might be delayed. Cheers
