GEHL 125 Parts Catalog

If you’re trying to rebuild a GEHL 125 Mix-All without the factory parts catalog, you’re wasting time and money. I’ve seen too many guys order the wrong bearing because they guessed from a generic drawing. This 78-page Parts Catalog gives you the actual part numbers, torque specs, and exploded views that match the machine exactly. No aftermarket guesswork, no “close enough” measurements that leave you with a half-assembled auger feeder on a Saturday night.

Page 2 spells out the orientation clearly: “Right and Left are determined from a position standing behind the Mixer.” That matters when you’re ordering the concentrate hopper side panel. The manual also tells you where to find the serial number – frame member at the rear base of the tank. Without that number, you’re guessing on every part.

Torque Specifications and Fastener Identification

The inside back cover of this catalog lists standard attaching hardware torque values. You’ll also find a hexagon symbol in the exploded views – that’s the foot-pound torque value for that specific bolt. Unless otherwise noted, all cap screws are Grade 5, zinc plated, and hex nuts are Grade B. If you skip torque on a Mix-All, you’ll get leaks, stripped threads, or worse – a flying part when the PTO engages. I’ve personally had to re-torque a whole gearbox because some cowboy used the “gut-tight” method.

Alphabetical Index: Your First Stop for Part Numbers

This catalog includes a full alphabetical index. Looking for the swinging auger feeder drive chain? Look up “Auger” and get the reference number, then flip to the exploded view. The index covers every component from “AR” (As Required) to “Wire” – no hunting through blurry scanned pages. Cross-reference that with the numerical index if you have a part number from an old order.

Numerical Index: Cross-Reference by Part Number

Already have a part number from the decal or a previous repair? The numerical index lets you jump straight to the exploded view page and verify fitment. This saves hours when you’re dealing with a machine that’s been through four owners and has mismatched bolts. Don’t trust aftermarket cross-reference tools – they don’t know that GEHL changed the feeder assembly design in mid-production. This catalog uses Form No. 907148, which replaces 906197, so you know you have the latest revision.

3 Sections That Save You Time

First, the Introduction section explains the tear-drop symbol for wet products (oil, grease) and hexagon torque callouts. Second, the Alphabetical Index gets you to the right page fast. Third, the Numerical Index confirms your part number. Spend ten minutes reading the intro, and you’ll cut your ordering time in half. The manual also lists fastener abbreviations – FCS for Flanged Cap Screw, FLN for Flanged Lock Nut – so you don’t order the wrong hardware.

What Does the 78-Page Parts Catalog Cover?

It covers the entire GEHL 125 Mix-All grinder mixer: the tank, swinging auger feeder, concentrate hopper, PTO drive, feed rolls, tire/wheel sets, and all attaching hardware. You get exploded views with reference numbers tied directly to the parts list. The catalog does not cover the engine – that’s a separate service manual. But for the driveline and mixing components, this is the only source I trust. this Wikipedia article on diesel engines might help if you’re swapping the power unit, but for the GEHL 125 itself, stick with this catalog.

Need to know the charge pressure for the hydraulic system? That’s not in this parts catalog – you want the service manual. But for ordering the right seal, bearing, or belt, this is it. this Wikipedia article on diesel engines is a good background read if you’re unfamiliar with diesel power, but don’t confuse generic info with factory specs.

Who Should Use This Manual?

Farmers maintaining their own equipment, small-shop mechanics, and home-garage enthusiasts who own a GEHL 125 or are thinking of buying one. If you’re a first-time owner, start by reading the Introduction on page 2 to learn the orientation and serial number location. Then use the Alphabetical Index to identify every part you see. The torque values on the inside back cover are critical – especially on the PTO shaft and auger drive. I’ve helped a neighbor rebuild a Mix-All using this catalog, and we didn’t order a single wrong part because we followed the numerical index.

Source Validity: OEM Reprint, Not Aftermarket Guesswork

This is a direct digital copy of the original GEHL Agriculture publication (Form 907148). No third-party redraws, no condensed versions that skip the washer sizes. The OCR text preserves the exact abbreviations and torque callouts. You can verify the serial number location and fastener grades against the machine. Aftermarket catalogs often use generic hardware ratings that don’t match the zinc-plated Grade 5 specs GEHL used. Don’t risk it.

Does this catalog include torque specs for every bolt?

It includes standard hardware torque values on the inside back cover and specific torque callouts in hexagon symbols on exploded views.

Can I find my serial number using this manual?

Yes. Page 2 tells you the serial number location: on the frame member at the rear base of the tank.

What if I need parts for the Swinging Auger Feeder?

That’s covered. The catalog includes a separate decal location for the SAF model number and full parts breakdown for the feeder assembly.

Will this catalog work for a different GEHL model?

This is specifically for the GEHL 125 Mix-All. Other models have different frame and driveline components. Use the correct manual for your machine.
