Thanks for the input, guys, I appreciate it.
I agree with all of you that've said that a smaller machine would have some material, significant advantages over most of the stuff I've been looking at. Totally, completely agree. I just don't believe 40-50hp is sufficient to do what I expect; namely, pulling an 8ft flail or a 10-12ft rotary cutter, set at its minimum cut height, uphill, through 24-30" of dense, wet, green clover, weeds, and grass, at 7-10mph+, and doing so effortlessly. As though the mower isn't even there.
Most mower manufacturers I've consulted recommend 50hp minimum for a mower of that size, and I suspect my expectations are unreasonable enough to mandate considerably more than the minimum recommended power.
On the basis of that reasoning, 65hp is about the least power I'm comfortable with, I'd rather be closer to 80.
With respect to the issues of buying old equipment, while I haven't done any significant wrenching on tractors, I
am a car guy; I've got a pretty diverse garage that includes everything from a '60 Buick to a Corvette Z06, a BMW M5, a turbodiesel Mercedes, a Subaru STI, and a bunch of other stuff. I'm pretty comfortable turning wrenches, and I'm pretty familiar with the decay and deferred maintenance that tends to afflict any older mechanical equipment.
That being said, while I fully expect to throw parts at anything this old on a regular basis, I'm not looking to turn it into a whole full-blown restoration, and that's
always a possibility with an older machine, no matter how well-cared-for it was.
To that end, if you guys have suggestions for newer machines that could be had with cabs and MFWD/4WD in this power range, I'd be open to hearing them. I don't really want to spend more than $15-20k if I don't have to.
Is there anything in the ~65-85ish horsepower range that I absolutely should
not buy? Specific models with known issues, expensive and time-consuming problems, etc.?
Went through the same thing last winter and it was a pain. Wanted a 75 horse 4mwd with a cab and good ac and looked at a lot of used ones. Nice tractors older than 2005 (there was a rough 10 year span on emissions for diesels) cost as much as a new one, the higher hour tractors were being sold for a reason (something expensive was going wrong)
Yes, that's one of the reasons I haven't pulled the trigger or even bothered to go look at anything in person yet; everything I'm seeing looks to have been beaten like a rented mule. People don't take care of their stuff. Applies to cars, apparently it also applies to tractors. What a pain.
