GEHL 2415, 2418 Parts Catalog – Factory OEM Parts Breakdown

If you have ever ordered a part for a mower conditioner only to find it doesn’t fit, you know the frustration. Wrong part numbers, missing reference diagrams, or relying on a worn-out decal that’s half-gone. I have been a master technician for 28 years, and I can tell you that guessing parts costs time and money. This GEHL 2415, 2418 Parts Catalog is the factory-issued document, not a reprint or a third-party compilation. It comes straight from GEHL Agriculture, form number 908177, and it is exactly what the dealer uses to identify every nut, bolt, cylinder, and wire on these disc mower conditioners.

Cutterbar and Disc Assemblies: Pages 14–21

You get separate exploded views for the DC2415 (pages 14–17) and the DC2418 (pages 18–21). Each diagram shows the cutterbar, discs, skid shoes, and all attaching hardware. Reference numbers point directly to the OEM part number in the list. Inside a hexagon symbol on the drawing you will find the torque value in foot pounds for that specific fastener — no need to flip to the back unless you are torquing standard hardware. The catalog also covers the tongue cylinder on page 11, which is a common wear item on these machines.

Electrical System Wiring and Components: Pages 38–41

Four full pages dedicated to the electrical system. You get the wiring harness layout, switch locations, and connector part numbers. If you have a lighting issue or a faulty solenoid, this section shows exactly which plug goes where. The service kits for electrical connectors are listed on pages 65–66, so you can order the correct weatherpack or Deutsch-style terminals. For background on the diesel engines that power the tractors running these conditioners, refer to this Wikipedia article on diesel engines.

Hydraulics and Gearboxes: Pages 42–47

The hydraulic circuit is laid out on pages 42–43, with component callouts for hoses, fittings, and cylinders. Gearbox breakdowns for the swivel hitch (pages 44–45) and the header gearbox (pages 46–47) include seal and bearing part numbers. If you need to rebuild a gearbox, you will see the exploded view with shim and snap ring details. The universal drives section (pages 48–52) covers the PTO driveline components and cross-references to the OEM shaft assembly.

Roller Drive and Roll Arms: Pages 24–27

The roller drive assembly and the roll arms are critical for proper conditioning. Pages 24–25 show the roller drive including sprockets, chains, and the tension system. Roll arms are on pages 26–27 with the pivot pins and bushings. All part numbers are included, and the torque values for the roll arm bolts are indicated in the hexagon symbols. The catalog also lists standard hardware torque specifications on the inside back cover for any Grade 5 or Grade B fastener not shown in the views.

GEHL 2415, 2418 Parts Catalog: What You Get Across 78 Pages

This is a 78-page document covering every assembly from the tongue (pages 8–10) to the trailer assembly (pages 30–31) and the axles and wheels (page 33). Decal locations are mapped on pages 2–7 so you can order replacement decals for your machine. The alphabetical and numerical indexes (pages 67–72) let you find any part number fast. If you also need the operator’s manual for daily operation, grab the GEHL 2415, 2418 User Manual – Factory Operator’s Manual for Disc Mower Condition. For other GEHL models, check the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog for skid loaders, or the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs for larger machines.

Torque Specs and Fastener Abbreviations – Inside Back Cover

Every fastener in the catalog is coded with standard abbreviations like CS for cap screw, FLN for flanged lock nut, and FW for flat washer. The inside back cover lists the torque values for these fasteners in foot pounds. Remember: unless noted, all cap screws are Grade 5, zinc plated. That matters when you are torquing a roll arm bolt or a gearbox mount. The catalog also warns you about the tear-drop symbol for wet applications (oil or thread locker) and the hexagon symbol for torque. These aren’t suggestions — they are factory specs.

Does this catalog cover the entire machine?

Yes, from tongue to cutterbar, including electrical and hydraulics.

What models are included?

The catalog covers both the GEHL 2415 and 2418 Disc Mower Conditioners. These are 15-foot and 18-foot cut models respectively. Each section, like the cutterbar, has separate exploded views for each model — pages 14-17 for DC2415, pages 18-21 for DC2418. The parts are clearly labeled with reference numbers and OEM part numbers. You will also find the serial number plate location on the left side of the main frame. Always use the correct model and serial number when ordering parts.

Are there torque specifications in the catalog?

Yes. Standard hardware torque values are printed on the inside back cover. Additionally, in the exploded views, a hexagon symbol with a number indicates the foot-pound torque required for that specific fastener. This is a factory spec you can trust.

Can I use this to order parts directly?

Yes, each part has a reference number and OEM part number for ordering.
