How close would the New Holland 65 and 273 be in hp requirements? ...
I can not quantify hp difference with numbers, but the NH 65 will take less hp as it has a 12" x 16" plunger where the NH 273 will be the bigger with the standard 14" x 18" plunger size plus a few more strokes per minute so it definitely will require more hp. Balers need to be somewhere around 540 PTO rpm so keep that in mind when using the Sherman or Hupp auxilary trannys since the frequently alter PTO speed too.
Here is my list of low hp balers in approximate increasing order of hp requirements:
a) old vintage baler with its own engine will be the least.
b) Microstar or other mini PTO driven baler especially designed for really small tractors even smaller and less hp than your 8N (drawback is pricey $15k or more new and not common to find used ones).
c) NH 65 compact baler (12" x 16" bale chamber, my personal pick because relatively cheap and parts interchange with other bigger/older NH models).
d) Ford 520 (12" x 16" chamber size like the NH 65 but hard to find parts for).
e) NH 66 (lots of wood inside, but kinda neat and designed for low hp tractors. 14" x 18" chamber size).
f) NH 67, or NH 68, JD 14T, JD 24T (I prefer New Holland over JD balers, but JD manual recommends JD 40 or equivalent as a tractor Power unit. A JD 40 tractor has less hp than your 8N. These will be 14" x 18" bale chambers).
g) Any new Holland baler number 69 to 273 (skip the NH 77 monster though. These will all be 14" x 18" bale chambers).
Numerous hours of reading available with some searching on this subject. You will find both success and horror stories. Best advice I can give is it is sorta like pulling a travel trailer with a full size truck that only has V6 engine. The V6 engine can pull a travel trailer (or baler) if it is sized appropiately to the power available. Mountains or hills and you need to go smaller on the trailer (baler). Raking is key to success too.
Here my smaller tractor with less HP and engine torque than you 8N pulling a NH 65 baler and it does NOT have live PTO either. Tractor is a Kubota L285 compact tractor of around 23 PTO hp at 540 PTO rpm. The one and only advantage that this Kubota does have over your 8N is a better selection of slower gears to choose from so the Windrow input can be adjusted accordingly to fit the limited hp available. N's tend to be fast in 1st gear so it will be critical to rake accordingly - an idiot on the rake will make for a long day since neither of these tractors have live PTO.
Wife sabotaged my pic as she painted herself out of it (she hates cameras).
