GEHL TR 600 Parts Catalog

If you’ve ever ordered a part for a TR 600 only to find it doesn’t fit because you didn’t know about the serial number split, you already understand why a factory parts catalog matters. That waste of time and money ends here. GEHL TR 600 Parts Catalog gives you the exact part numbers, exploded views, and assembly breakdowns GEHL intended – not some re-drawn aftermarket guess. I’ve seen too many guys install the wrong sickle section because they used a third-party cross-reference. This 24-page OEM document keeps you out of that hole.

Frame Assembly and Divider Sections (Pages 4–7)

The frame section on pages 4–5 shows every bracket, weldment, and hardware grouping for the main chassis. Note the warning on page 4: “Order By Part Number – Do Not Use Illustration Reference Numbers.” That’s factory speak for “use the part number in the list, not the callout bubble.” The divider assembly on pages 6–7 follows the same logic – you get a clean exploded view and a matching parts list. Right and left are defined from a position standing behind the unit facing the gatherer shoes, as stated on page 2. If you ignore that orientation, you’ll order the wrong side panel. I’ve seen it happen.

Gatherer Center Section: Serial Number Split (Pages 8–11)

This is where the catalog earns its keep. The gatherer center section is split into two separate assemblies: one used after serial number 7725 (pages 8–9) and one used before serial number 7726 (pages 10–11). No guessing – you check your serial tag, find your range, and order from the correct page. Aftermarket catalogs often combine these into one generic drawing. That gets you the wrong gatherer drive. The OEM layout also includes hardware callouts (HN, HLN, PW, LW) with the full abbreviation list on page 2. You’ll see those abbreviations on every parts list – they mean hex nut, lock washer, plain washer, etc. Learn them.

Gatherer Assembly: Two More Serial Number Groups (Pages 12–17)

Same split applies to the gatherer itself. Pages 12–14 cover units after serial 7725; pages 15–17 cover before 7726. Each page group has its own parts list keyed to the illustration. If you’re rebuilding a TR 600 that’s been through multiple owners, verify the serial number before ordering gatherer components. The manual includes the left-hand thread notation (L.H.) where applicable – something cheap reprints often miss. I keep a copy of this section in my toolbox because the gatherer tines wear fast and the part numbers change with the serial break.

Sickle and Sickle Drive (Pages 18–20)

The sickle section covers the knife sections, guards, hold-downs, and the drive assembly. Double Pitch Tooth (DPT) and National Fine Thread (NF) are called out explicitly. If you’re replacing a sickle section, you need the correct DPT count or the drive will bind. The manual’s exploded view on page 18 shows exactly how the pitman arm connects to the sickle head. Page 20’s parts list gives you the complete drive hardware – bearings, shaft, sprockets. No aftermarket manual I’ve seen gets the bearing part numbers right for the TR 600 sickle drive. This one does, because it’s OEM.

Decal Locations and Safety Compliance (Page 3)

Page 3 documents every safety decal and its location on the machine. The decal set number for the TR 600 is 044180, and the manual explicitly warns: “Always order Decals by set number. DO NOT order Decals separately.” That’s important because individual decal part numbers aren’t listed – only the set. The page also covers surface preparation (clean, degreased) and the correct application method. If you’ve painted your TR 600 or the decals are faded, this page saves you from buying the wrong set. I’ve used it to verify decal placement after a frame swap.

Numerical Index for Fast Part Lookup (Pages 21–22)

Every part number in the catalog is indexed numerically on pages 21–22. That means you can start with a worn-out bolt, look up its number from the index, and find which assembly it belongs to. This is more useful than you think when you’ve got a pile of parts from a disassembled machine and no idea where they go. The index cross-references to the page where the part appears. No flipping through the whole book.

OEM Documentation vs. Aftermarket Copies

I’ll say it straight: I trust factory GEHL manuals and I distrust aftermarket documentation on principle. The TR 600 Parts Catalog from AutoRepairManuals is a direct scan of the original Form 901576 (replaces 900999). The page numbers, part callouts, and serial splits are preserved exactly. Aftermarket versions often renumber pages or combine assemblies, which leads to ordering the wrong part. This is the real thing. If you want to understand how diesel engines work before diving into repairs, check out this Wikipedia article on diesel engines, but for ordering TR 600 parts, you need the factory print. For more GEHL equipment, see the related manuals: 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. Also, this Wikipedia article on diesel engines provides good background on the powerplant that drives your TR 600.

Who Needs This Manual?

Home garage enthusiasts and small-shop owners who maintain a single TR 600 or a fleet of them. If you’ve ever wasted a Saturday driving to the dealer for the wrong gatherer sprocket, this catalog is the fix. You don’t need to be a master technician – you just need to read the serial number plate and match it to the correct parts page. The manual assumes you know basic tools and safety. It does not assume you’ve memorized 24 pages of part numbers. That’s what the book is for.

FAQ

What serial number breaks are covered in this catalog?

Two serial splits: after Serial No. 7725 and before Serial No. 7726. The gatherer center section and gatherer assembly each have separate pages for each range.

Does this manual include wiring diagrams or hydraulic schematics?

No. This is a parts catalog only – exploded views and part numbers. It does not contain service procedures, torque specs, or hydraulic routing. For those, you need the service manual.

Are decals included in this catalog?

Yes, page 3 shows decal locations and the set number 044180. The manual instructs you to order the entire set, not individual decals.

Can I order parts directly from the part numbers in this manual?

Yes. The numerical index on pages 21–22 lists every part number in the catalog. Take that number to a GEHL dealer or online parts supplier. The catalog also notes that common hardware (nuts, bolts) is listed but not illustrated – you must order them separately.

Get the right part the first time with the factory manual. Access the Factory Manual from AutoRepairManuals and keep it in your shop – or on your tablet – every time you tear into a TR 600. No more guessing, no more wrong orders. That’s what OEM documentation does for you.
