GEHL DC1080 Parts Catalog

You’ve got a GEHL DC1080 disc mower conditioner that’s down because a bearing seized or a knife broke. You crack open some aftermarket parts list you found online and the part number doesn’t match the casting mark. You waste an hour cross-referencing, order the wrong piece, and the machine sits another day. This is exactly why you need the actual Parts Catalog – the one GEHL printed for their dealers. 48 pages, factory-issued, not a reprint from some third-party.

Specifications and Check Lists – Where to Start

Flip to page 4 for the specifications table. You’ll find machine weights, cutting width in inches, PTO speed requirements, and fluid capacities. The check lists on pages 5–7 break down daily, weekly, and seasonal inspection items. These aren’t generic suggestions – they’re factory intervals for the DC1080 driveline and cutterbar. Miss a lube point and you’re buying a new gearbox.

What’s in the Service Parts Section?

Pages 22 through 39 are the meat of this catalog. Exploded-view drawings show every nut, bolt, blade, belt, and bearing. Each part gets a callout number and a corresponding GEHL part number. Need the knife section assembly? It’s right there. The conditioner roll drive chain? On page 28. You don’t guess – you read the number, order it, and bolt it on. The Numerical Index on pages 44–45 helps you find a part number quickly if you only have a casting identifier.

3 Sections That Matter Most to a Working Mechanic

First: Safety (page 8). It lists the decal locations and hazard warnings that must be legible on the machine. I’ve seen guys skip this and then wonder why a PTO shaft guard is missing. Second: Decal Locations (pages 42–43). You need to know exactly where that “Rotating Blades” sticker goes after a repaint. Third: General Information (pages 9–21) – it covers serial number identification, proper paint codes, and hardware grade specs. Ignore them at your own risk.

Order the Right Part the First Time

Every time you order a roller bearing or a knife section without the factory part number, you gamble on returned freight. This catalog eliminates that. You read the diagram, you call your dealer with the GEHL number, and the part arrives correct. It’s not a repair manual – it won’t walk you through replacing a cutterbar seal – but for sourcing genuine components it’s the only source you should trust. For engine components listed in the catalog, cross-check with this Wikipedia article on diesel engines for general knowledge, but stick to the GEHL number for ordering.

Safety and Decal Locations: Why They Matter

Page 8 is not optional. The safety section lists every warning label that should be on the DC1080, from pinch-point warnings to thrown-object hazards. I’ve worked on mowers where someone painted over the decals. That’s a lawsuit waiting to happen. The decal location illustrations on pages 42–43 show you exactly where each sticker goes – height from the frame, distance from the hitch. Use them.

Related manuals you might need: GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog, GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs, and GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual.

If you’re rebuilding an engine and need general theory, this Wikipedia article on diesel engines is a decent primer, but it won’t help you find a piston ring for the DC1080’s power unit.

Does this manual have torque specifications for the cutterbar bolts?

No. This is a parts catalog, not a service manual. Torque values come from the separate Operator’s or Service Manual.

How do I find a part number if I only have the old part in hand?

Use the Numerical Index on pages 44–45, which lists GEHL part numbers in ascending order. You can also flip through the exploded diagrams and match the shape and location.

Is this the same as the manual that came with my new DC1080?

Yes. This is the official GEHL publication – same content as what dealer techs have. It’s the 48-page parts catalog, not an operator’s handbook.

Can I use this to order parts for a different model year?

This catalog covers the DC1080 as originally manufactured. For revisions, check the serial number break on page 9 and compare to your machine’s plate.
