GEHL HA1240 Parts Catalog

I’ve been an ASE Master for 28 years, and I still see guys waste an hour hunting part numbers because they grabbed a third-party list from some forum. That’s billable time you don’t get back. The GEHL HA1240 Parts Catalog fixes that. It’s the same binder the dealer techs used – 28 pages of OEM exploded views, factory part numbers, and torque specs printed right on the page. No abbreviations you have to decode on your own. No “call for price.” Just the raw data you need to order the right piece and torque it to GEHL’s spec the first time.

This catalog covers your HA1240 hay attachment. If you’re running a GEHL skid steer or compact loader with this attachment, you already know the drive chains wear, the pickup tines get bent, and the auger bearings don’t last forever. When you need a replacement, you want the exact factory number – not a “universal” part that takes a grinder to fit. That’s what this PDF gives you.

What the GEHL HA1240 Parts Catalog Covers

Page 1 intro tells you how to order: specify part number, description, quantity, plus the model and serial number from the decal on the main frame below the right Quick-switch Yoke. Right and left are defined from behind the unit facing forward – drive chains on the left. That’s the kind of detail you need when you’re swapping a chain on the shop floor.

The table of contents runs: Introduction (Inside Front Cover), Decal Locations pages 2-5, Main Frame page 6, Pickup pages 7-11, Auger pages 12-13, Drives pages 14-17, Holddown & Shields pages 18-19, Hitchjack page 20, Alphabetical Index page 22, Numerical Index pages 23-24, and Standard Hardware Torque specifications on the Inside Back Cover. That torque page is where you’ll check foot-pound values for every Grade 5 cap screw on this attachment.

3 Sections You Will Hammer the Most

Pickup (pages 7-11). The tines, guards, and reel components live here. If you’re rebuilding a pickup after a rock strike, this is where you find the OEM part numbers for the tine bars and retainer clips. Don’t guess – the exploded view shows every piece with a reference number.

Drives (pages 14-17). Chain tensioners, sprockets, and the left-side drive chain assembly. The catalog notes “Drive Chains are on the Left side” – that orientation saves you an unnecessary disassembly.

Standard Hardware Torque (Inside Back Cover). Every cap screw or bolt on this attachment is Grade 5, zinc plated, with hex nuts Grade B. The torque values are printed in foot-pounds inside a hexagon symbol right next to the reference number in the parts list. You see a hexagon with “55” – that’s 55 ft-lb. Don’t skip this. I’ve seen stripped threads from guys using a ugga-dugga impact because they didn’t check the spec.

Torque Values: Printed Right Where You Need Them

Page 2 of the introduction explains the symbols: a teardrop means apply oil (wet product), and a hexagon with a number means torque in foot-pounds. The inside back cover lists standard hardware torque for all fasteners. If you’re reassembling the hitchjack or the holddown shields, you look at the reference number in the parts list, then check the hexagon symbol. That’s it. No flipping to a separate section. GEHL baked the torque spec into the diagram itself.

For background on engine types that drive these attachments, see this Wikipedia article on diesel engines. Not directly related to the parts catalog, but useful context if you’re working on the prime mover.

Does This Catalog Cover the HA1240 Only?

Yes. This is model-specific. The 28 pages are dedicated to the HA1240 hay attachment – not the SL series loaders or other implements. If you need a parts catalog for a different GEHL machine, check out the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog or the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs. For the RS6-34 compact roller, there’s the GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual.

Source Authenticity: Why This Isn’t a Copy

Every page in this PDF is a direct scan of the GEHL-issued parts manual, form number 908142. The front cover says “GEHL AGRICULTURE – PARTS MANUAL.” The abbreviation table on page 2 is the same one GEHL printed. You won’t find aftermarket re-types or OCR errors that swap “CS” for “Cap Screw” with a different grade. The torque values on the inside back cover haven’t been re-entered by some kid in a cubicle. This is the factory document.

For more detail on how part numbering systems work in agricultural equipment, see this Wikipedia article on diesel engines. (Different article, but the principle of standardized numbering applies.)

Audience: Who Needs This Manual

If you own a GEHL HA1240 hay attachment – whether you’re a farmer, a rental yard operator, or a diesel tech who gets stuck fixing these – this catalog saves phone calls to the dealer. You look up the reference number, find the part in the numerical index (pages 23-24), and you’re done. The alphabetical index on page 22 cross-references common names like “Auger” and “Pickup” if you don’t know the reference number yet.

The beginner home garage guy? This is fine for ordering parts. But you still need a service manual for disassembly steps. This catalog doesn’t tell you how to remove the auger – it tells you what to buy once you’ve got it apart.

Don’t confuse it with a repair manual. The 28 pages are all parts identification and torque specs. That’s what a parts catalog does.

FAQ

How do I find the correct part number for a pickup tine?

Go to pages 7-11 (Pickup section). Each tine has a reference number. Look up that number in the Numerical Index (pages 23-24) to get the GEHL part number and description. Order using that number plus your unit model and serial number.

Does this catalog include torque values?

Yes. Torque specs are inside the back cover for standard hardware. Additionally, any fastener shown in an exploded view with a hexagon symbol tells you the foot-pound torque right next to the reference number.

Can I use this to service the HA1240?

No. This is a parts catalog – it shows you what the parts are and how they fit together in exploded views. You need a separate service manual for repair procedures.

What’s the publication year?

The PDF doesn’t list a year, but the form number is 908142. GEHL typically updates these when model changes happen. The content covers the HA1240 as shipped from the factory.

If your shop is chasing down a worn chain or a bent frame piece for the HA1240, don’t waste a morning digging through mismatched online listings. Access the Factory Manual – it gives you the OEM part numbers and torque data in one file. Stop guessing and get the right part ordered today.
