Thanks for all the comments.
I don't think I need a big 8 wheel monster for cutting the hay. The goal is to cut the hay, not smash it flat afterall.
I'm not seeing a lot of Deeres locally in the right age/price range, although a lot can come up in the next few months. I'd just like to get all my ducks in a row before the crunch this summer.
I'll keep in mind the comments about the 30+ year hydros. I suppose I'd much prefer a pickup with 200K miles with a stick shift rather than an automatic.
So, the IH Hydro 84, isn't running , and may be low on the power range, or at least would be run on pretty high on its power profile. So, you aren't recomending it.
That leaves the IH 884 as high on my list.
72 HP PTO
Dual 540/1000 PTO
4x4
Appears to have a 2 pt to 3 pt hitch conversion.
It sounds like it has some issues with the transfer case. Reply from seller:
There is a gear box that mounts to the transmission that runs the front drive line. In that gear box for some reason two of the gears broke. There is no damage other than the two gears and the shafts they ride on that I know of. Never priced out parts to fix it.
As far as 4x4. I know it may not be necessary, at least until it is.
The first year my parents cut hay, they did manage to get a self propelled hay mower/conditioner stuck in the middle of their hay field. And tractors stuck on more than one occasion (spring fertilizing?)
I'll try to pick up the field below my house. Last year they brush hogged it. It has patches of swamp grass growing in the middle of it (cutting around it for hay, of course), but it does mean there is risk of breaking through the turf.
Anyway, I've been wanting to try to cut some gears... perhaps the transfer case will give me an opportunity to play with the lathe and milling machine.
There is an International Farmall 560 for very cheap. But, it appears to just have a drawbar, without 2pt/3pt, and running the hydraullic pump off of the PTO. Thus, it would require significant modifications to make it usable in the field. Still, building a new hitch might be worth saving a couple of thousand off of the price. It is a bit old though.
