GEHL SL5635, SL6635, 5635 DXT, 6635 SXT Operators Manual

You’ve got a GEHL SL5635, SL6635, 5635 DXT, 6635 SXT on your lot or in your shop, and you need the actual factory Operators Manual—not a photocopy, not a third-party rewrite with guesses for torque values. I’ve been turning wrenches for 28 years, and I’ve seen what happens when someone follows the wrong spec. That’s why I’ll only trust an OEM document for critical numbers like fluid capacities, bolt torques, and safety decal placement. This 83-page manual is the real deal, straight from GEHL.

Model Specifications and Identification

Inside the front cover you’ll find a full page of international symbols—engine start, stop, hydraulic oil temperature, the lot. Page 1 gives you the model and serial number location: a decal inside the right frame. Write those numbers down. You’ll need them anytime you order parts. The table of contents lists model-specific specs starting on page 4. That section covers rated operating capacity, travel speeds, and hydraulic pump flow for the SL5635, SL6635, and the DXT/SXT variants. No guesswork.

Torque Specs: What You’ll Find on Page 78

Torque values are the backbone of any rebuild. This manual dedicates page 78 to torque specifications. Wheel lug nuts, hydraulic fitting torques, engine mounting bolts—all listed in foot-pounds. I’ve seen too many stripped threads because a tech used a generic chart from a forum. Use the factory numbers. If you’re working on a 5635 DXT, the same specs apply because the drivetrain is shared. Need general background on fastener tightening? Check Manual Transmission for theory, but for this machine, trust page 78.

7 Systems Covered in the Checklists

Chapter 3—Checklists—starts on page 7. Seven pre-operation checks: engine oil level, hydraulic reservoir, tire condition, floor mat condition (yes, it matters for foot pedal control), safety arc warning decals, seat belt, and the ROSS (Ride‑On Safety System) function. Each checklist has a box to mark off. Use them every day. I don’t care if you’ve run a loader for twenty years; skip one check and you’ll bleed a hose.

Understand the Controls Before You Start

Chapter 5 (page 19) lays out the entire control layout: hand controls, foot pedals, gauge panel, and the safety equipment like the seat belt and parking brake. The manual shows you how to test the neutral start switch and the operator presence system. If you’ve got a new operator or a rental customer, this section saves you a phone call later. Pair it with GEHL SL5635 SL6635 1999 Engine Parts Book if you need engine component diagrams.

Who Needs This Operators Manual?

Home garage guys who bought a used SL6635 at auction. Small farm owners running a 5635 DXT for loader work. Even experienced mechanics who want the correct cold-start procedure for the diesel engine. This manual doesn’t assume you know anything—it shows you where the glow plug switch is, how to engage the parking brake, and what the warning lights mean. Beginners, use chapter 9 (Troubleshooting, page 52) to diagnose starting issues or hydraulic drift. Professionals, you’ll use chapters 7 (Adjustments) and 10 (Service) for linkage tweaks and filter changes.

Safety Decals and Their Locations

Chapter 4 walks through every safety decal: “Read Operator’s Manual,” “Stay Clear of Moving Parts,” “No Riders,” and the hot-surface warning near the exhaust. It tells you the exact location on the loader—for example, the tie-down decal is on the chassis near the rear counterweight. If a decal is missing, the manual gives you the part number to order it. This is OEM-only info; aftermarket reprints often leave out the placement diagrams.

Does this manual cover the 5635 DXT and 6635 SXT models?

Yes. The title includes both DXT and SXT variants. All service specifications, operator instructions, and torque values apply to those models as well.

What if I need a parts catalog instead of the operator’s manual?

Parts breakdowns are not in this document. For exploded views and part numbers, get the GEHL SL5635 SL6635 1999 Parts Catalog or the GEHL SL4635 SL4835 SL5635 SL6635 2005 Parts Catalog. For general transmission repair concepts, see Manual Transmission.

You’ve got the loader, you’ve got the tools. Now get the right instructions. Access the Factory Manual from the AutoRepairManuals collection and put it on your tablet or print the pages you need. It’s the difference between a job done once and a job done twice.
