This is my situation. My dad is 78 years old, loves farming, and has always had to make do with tractors that may or may not make it thru the day without breaking down. I want to surprise him when hay season gets here in a few weeks with a new, or nearly new tractor. Now, I'm not too bright when it comes to tractor specs. I want a tractor that will handle a 5x6 hay roller, a 17' tedder, a 9' disk mower, and a 15' batwing rotary cutter. All on rolling land. Will probably go 4wd with a loader. I will be choosing between Case, McCormick, Kubota, and New Holland due to local dealers. What do I need in terms of a dependable transmission, horse power, etc. What brand and model best suits my needs? Tractor will be used about 400 hours per year haying, hogging, & feeding hay. Probably going with a cab tractor for dad's comfort. Please advise me as to what I need and should expect to spend. Thanks.
