New Holland 492 Haybine

Dad and I just purchased a New Holland 492 haybine. We seemed to have got a decent deal on it. Wondering what HP you would recommend using on it. We have a 35hp JD 830 3 cylinder, or we might use it on the Oliver 1655 diesel if need be.

Wondering if anyone can tell me what year it is. The serial number is:

895606

Thanks for the input in advance. It sure was not fun driving it home! Darn thing stuck out real wide! Can't wait to try it out in the spring.
 
I've got a 489 that I run on a 52 hp Ford. If I remember correctly, the manual says 35hp minimum. But I could be wrong,
 
I pull my NH 460 9 foot cut hay-bine with my Oliver 77 and it plays with it so that JD should handle it just fine on all but a steep hill that is
 
Your NH 492 is a 1996 model. It is a 9 foot 2 inch cut. In light hay the JD 830 will pull it but in heavy hay you will need the Oliver 1655. It also depends on how fast you want to mow. To keep a fairly fast ground speed in heavy hay will take more horsepower than the JD 830 has.

Had a friend that had a NH 488 haybine. He tried to run it with his WD 45 and had sickle problems all of the time. The ground speed was wrong for the PTO speed. IT was wedging the sickle full and then having to shear it packed full. He switched to his AC 185 and the sickle issues went away. This was in waist high thick timothy and heavy alfalfa.

IF your hay is thinner then you may get along with a smaller tractor but I would not risk it myself. You need a tractor with the HP to hit a thick spot and pull through without bogging down.

Also like rrlund pointed out the Oliver is a lot nicer tractor to ride across a field than the smaller JD 830 utility tractor.
 
Now is the time to run it a little and listen to the gearbox. If it clatters bad it needs rebuilt.
Check the guards. New, gap is about.150. Anything over .275 toss em.
Check the register. When sickle is full right it should be centered with guard.
How are the sections. New sickle needed? Buy one with bolts and serrated.
When rejuvenated sickle is in, get a .025 feeler gauge. Bend all the guards until you have this between the bottom of the sections and the guards.
Check your oil level, give her a good greasing and go make hay.
