Good morning everyone I’m new to the forum so I look forward to reading all the good information on here so thanks for having me! So my question is this me and my wife are looking to buy another tractor something big enough to run all our hay equipment and pull our Woods B320 20ft batwing. Hay equipment wise we just run a 10ft disc mower v-rake and a Vermeer 504R roller. We would also like to feed with this tractor as well in the winter so 4wd is a must we live in Kentucky so once winter hits it gets a little sporty here lol also Cab and a loader would be a must as well we’ve got a JD 4030 and love it so I’d like to stay green maybe a 64 series tractor? anything to get us in the right direction helps thank you all!
Your 4030 makes right around 100 HP, so if it does a decent job running your equipment, just get something in that size range. You start to see MFWD units in that size showing up in the 50 and 55 series (e.g. 4050, 4055), but in general you would need to look at a 6000 series machine to see very many with MFWD. A 6400 as you mentioned would work, as would its successors the 6410, 6420, 6330, or the 6100D, 6105D, 6100E, or 6105M units that came later. One of the earlier small-frame rowcrops like the 7200, 7400, 7210, or 7220 would be in that same power range as well and would be considered the direct descendants of your 4030.
The batwing would probably be the toughest thing you mentioned pulling as the other equipment can be run on a 75 HP tractor. Most of the people using 20' batwings use a tractor of at least 120 HP or so.
