A small square baler (like a NH 68 through a 271 or along those lines) really only uses 15 hp to run the baler. The big flywheel does all the work, the pto just keeps the flywheel up to speed. However, balers are heavy, and it takes about the same hp to pull one + the tractor around. That about uses up all your power. Don't expect to pull a wagon too yet. (Maybe you can, but don't expect to!) If you are on hills, that is more stress on your tractor, more so on the brakes,which were never great on the N series to begin with, and only worse with age. A LOT of weight for you to control, if you are on hills. And it seems most hay ground is hills.... Then the big negative for a tractor with barely enough power to run the baler - no live pto on an N. If you drive along & come across a thick windrow of hay that is bogging your tractor down, as soon as you push in the clutch to stop moving, the pto also stops & the baler plugs up. Then the N series doesn't have a whole lot of slow gears to choose from either! You can get through this, by learning to quick-shift into & out of nuteral, plan ahead & do so before the baler does bog down, and by making thin windrows of hay. But, it _is_ a pain, despite all the hay that has been baled with a small tractor without live pto - no way around it, it's a bother. With all those negatives, note that lots & lots & lots of hay has been baled with just such a setup. It is not ideal, but it does make hay. On 4 acres, you really don't have a choice - doesn't pay to get anything else, and driving slow really isn't a big deal on such few acres. There are balers with 2 or 4 cylinder engines (mostly Wisconsin) on them instead of a pto. This takes some power load off of the tractor, & allows you to use the clutch & throttle to change speeds while the baler continues to bale. However, it adds weight to the baler making it harder to pull & stop, and is yet another engine to fool with and try to keep running on a seasonal machine. Your choice on that issue! :) :) As most of us say, the NH & JD balers got things figured out right, first, and cost more, because they are more likely to make good bales and have parts & knowledgeable mechanics all over the place. Other brands of old balers are cheaper, but seem to have more problems. Doesn't mean other balers are always junk, but it's like playing a horse race - you have better odds going with either a NH or JD. Again, your choice, take any color you want. :) --->Paul
