GEHL 2245, 2275 Parts Catalog: Factory OEM Parts Breakdown

If you’ve ever stared at a worn-out wobble arm or a leaky cylinder on a GEHL 2245, 2275 Parts Catalog and wondered whether the replacement bolt should be Grade 5 or Grade 8, you know the cost of guessing. Twenty minutes lost cross-referencing aftermarket charts, another call to the dealer, and still no torque number for that header lift cylinder. This catalog puts the factory breakdown in your hands — no third-party reinterpretation, no generic torque tables pulled from a 1980s textbook. It’s the same document GEHL sent to dealers, and it covers both the 2245 and 2275 models.

Component Breakdowns: Cylinder Assemblies and Torque Data

The manual dedicates pages 35–40 to component breakdowns. You’ll find the Tongue Swing Cylinder and Header Lift Cylinder drawn out with every cap screw, flanged lock nut, and seal called out by part number. Need the torque for the cap screw that holds the gear reduction assembly? It’s listed right there on page 36 — in foot-pounds, not Newton-meters. The inside back cover gives you standard hardware torque specs for Grade 5 bolts, so you can double-check without flipping back to a separate chart. This is the kind of detail that keeps a mower conditioner running through a second cutting season instead of sitting in the yard with a stripped thread.

Decal Locations and Safety Warnings

Pages 2–5 show every decal on the machine — where it goes, what it warns about. GEHL didn’t slap stickers on randomly; each decal corresponds to a specific hazard point. When you replace a shield or rebuild the auger drive, you’ll know exactly which warning decals need to go back on. I’ve seen guys skip this step because the aftermarket parts diagram didn’t show them. Then some kid walking behind the machine catches a pant leg in the PTO. Don’t be that guy. The manual calls out every decal by part number, so you can order replacements and keep the machine legal and safe.

Gearbox and Pulley Assembly: What the Manual Covers

Page 22 walks through the gearbox and pulley drive. The exploded view shows the input shaft, bearings, and sheaves in relationship to the conditioner drive. If you’re replacing the pulley on a 2275 and wondering whether the bushing is the same as the 2245, the parts list tells you exactly which reference number applies to each model. The manual also includes a note about “Right” and “Left” determined from behind the mower — something a lot of guys get backward when ordering a sickle drive arm. Save yourself a return trip to the parts counter.

Reel and Auger Drive: Part Numbers Without the Headache

Auger & Auger Drive on page 12 and Reel Assembly on page 14 are laid out so you can see how the drive chain routes and which sprockets are common between the two models. The manual uses reference numbers that correspond to a parts list with descriptions like “Flanged Cap Screw, Grade 5, 3/8-16 x 1.25”. No ambiguous “bolt as required” nonsense. You also get the abbreviation key on page 2 — so when you see “FCS” in the list, you know it’s a flanged cap screw, not a flat head machine screw. That level of precision cuts ordering errors by a long shot.

Hydraulic Motor, Lines, and Filter: Factory Routing Diagrams

The hydraulic motor section on page 20 shows the lines and filter in relation to the pump assembly. If you’re retrofitting a used 2275 header onto a 2245 frame, the hydraulic motor mounting points are called out with specific bolt lengths and grades. The manual includes a tear-drop symbol for wet assembly — oil or sealant required at that joint. I’ve seen guys slap a dry O-ring into a hydraulic fitting because the aftermarket manual didn’t flag it. That leak costs you half a quart of hydraulic fluid and an afternoon of bleeding air. The OEM catalog flags every wet joint.

7 Systems Covered: From Tongue to Forming Chamber

This 53-page catalog breaks the machine into 7 major groups: Tongue & Hitch, Gearbox Pump, Header Frame & Auger, Reel & Sickle, Conditioner & Drive, Trailer Frame & Axles, and Shields & Forming Chamber. Each section starts with a master exploded view, then dives into subassemblies. The optional equipment section (page 41) covers the Center Skid Shoe Kit, Tall Crop Divider Kit, and Gauge Wheel Kit — all with separate part numbers. If you’re adding a transport lighting kit (page 42), the wiring harness part is itemized. You don’t have to call the dealer for a harness PN.

Source Validity: OEM Print vs. Aftermarket Copies

I’ve been handed “compatible” parts catalogs that listed the wrong bolt grade for a sickle guard. Then the guard falls off in the field and wads up the reel. This GEHL catalog is the original factory print — not a scanned reprint from a third-party aggregator. The attached hardware torque table on the inside back cover matches GEHL’s engineering specs. If you want to compare it to other GEHL manuals, check out the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog or the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs. For loader applications, the GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual follows the same factory documentation standard. And if you’re curious about the diesel engines that power these machines, this Wikipedia article on diesel engines gives a solid technical background, though I’d still trust the GEHL service manual over any Wikipedia page for actual repair procedures. For more on combustion engine fundamentals, this Wikipedia article on diesel engines is a decent primer.

Does this manual cover both the 2245 and 2275 models?

Yes. The catalog covers both model numbers. Part callouts in the exploded views will indicate which model a specific component belongs to. Torque specs and hardware grades are the same for both unless noted.

What torque values are listed in the manual?

The inside back cover lists standard hardware torque for Grade 5 cap screws and Grade B hex nuts. Some component breakdowns (pages 35–40) include specific torque values in foot-pounds next to the reference number, shown inside a hexagon symbol.

Are decal part numbers included for reordering?

Pages 2–5 list every decal by part number. If your 2275 is missing the PTO warning sticker, you can order the correct one from the reference number.

Can I use this catalog to identify hydraulic cylinder seals?

Yes. The Tongue Swing Cylinder and Header Lift Cylinder are broken down on pages 35–36 with individual seal part numbers. The manual does not include seal cross‑reference dimensions, only OEM GEHL part numbers.

You can run a mower conditioner on aftermarket parts and guesswork, or you can hand your technician the actual factory parts catalog. The choice is yours. Access the Factory Manual and start ordering the right parts on the first call.
