New Holland 274 Parts Catalog

If you’re chasing a part number for a New Holland 274 baler and you’re tired of guessing, this is the document you need. It’s a factory Parts Catalog – 74 pages, direct from New Holland, not some aftermarket reprint. I’ve seen too many guys order a ‘looks-about-right’ part and end up with a baler that won’t tie. This catalog gives you the exact OEM number, the exploded diagram, and the group reference. No guesswork. That’s the difference between a job done right and a weekend of headaches.

Every group in this catalog is laid out the way New Holland intended. The P.T.O. group on page 6, the clutch and flywheel guard on page 7 – each one has a clean illustration with numbered callouts. You match the callout to the part number list, and you order the exact piece. There’s no flipping through generic diagrams that don’t line up with your machine. This is the real thing.

Drawbar and PTO Groups: Where the Tractor Meets the Baler

Page 4 covers the drawbar group – the hitch that connects the baler to your tractor. Page 6 shows the P.T.O. group, including the driveline components. If you’ve ever sheared a PTO shaft because you ordered the wrong U-joint, you know why exact numbers matter. This catalog lists the original part numbers, so you don’t end up with a mismatch that binds up under load. The clutch and flywheel guard group on page 7 is also critical – missing or wrong guard bolts can let the shield drop into the flywheel. That’s a safety hazard I don’t want to see.

What Does the Plunger Group Cover?

The plunger group on page 14 is the heart of the baler – it compresses the hay into bales. Worn plunger bearings or a cracked connecting rod will kill your bale density. The catalog shows every bushing, bolt, and retainer in that assembly. You need the plunger stop? It’s in there. The knife section? Also listed. Don’t try to eyeball these parts; the plunger runs at high speed and a wrong part can cause catastrophic failure. Use the OEM number from this catalog.

3 Groups You Can’t Afford to Misidentify: Guards, Wheels, and Accessories

Pages 40 through 46 cover the wheel and axle group, plus the front, base, and rear guard groups. The guards are there to keep you from getting wrapped up in the driveline – they’re not optional. The wheel group includes the hub and rim assemblies. If you need a new tire or a bearing, the part number is on page 40. Then the additional accessories on page 60 list things like the wagon hitch, bale chute, and the manual pick-up lift attachment. Again, all OEM numbers.

Get the Right Part Number: Using the Index

Page 63 is the index. It lists every group alphabetically or by page number. Flip to the index, find the component you need, then go to that page. The catalog also includes ordering instructions on page 1: give the model and serial number, write the complete part number and description, and note that left/right are from the operator’s position facing forward. Follow those instructions and you’ll get the right part the first time. I’ve seen too many guys skip the serial number and end up with a part that doesn’t fit earlier or later production runs.

Knotter Group: OEM Specs vs. Aftermarket

The knotter group on page 30 is the most finicky part of any baler. If the knotter timing is off, the bales fall apart. The OEM parts catalog lists exactly the billhook, twine disk, and needle assembly that New Holland designed. Aftermarket parts catalogs often substitute a different billhook geometry that changes the knot timing. Don’t do it. Stick with the factory numbers. The twister group on page 50 and wire guide group on page 54 are equally critical if you’re running wire instead of twine.

This manual is for anyone who owns a 274 Hayliner baler – whether you’re a farmer, a mechanic, or a collector. If you need to replace a worn tine or a broken shear pin, you need this catalog. For background on baler mechanics, see the Automotive Industry Overview on Wikipedia. Also check Automotive Industry Overview for general context on agricultural equipment.

This is a genuine New Holland factory publication. The part numbers are the ones New Holland used when they built the machine. Aftermarket parts catalogs often substitute numbers or omit supersessions. Not here. You get the original print, not a scanned copy with blurred callouts. The OCR excerpt from the original file shows the ordering instructions and the exact group layout – that’s the level of detail you’re getting.

How do I find the correct part number for my baler?

First, locate your baler’s model and serial number. Then find the group that contains the part (e.g., Pick-Up Group on page 26). Look at the exploded diagram and note the reference number. Then cross-reference to the part number list. Always verify the description matches the part you need. The index on page 63 helps you locate groups by name.

You don’t have time to order wrong parts. Access the Factory Manual and get the right part numbers the first time.
