GEHL HA1110 Parts Catalog – Factory OEM Parts Manual

I’ve seen too many junior techs try to rebuild a Hay Attachment using a photocopy of a photocopy of a parts list. Then they call me asking why the auger won’t clear or why a bolt sheared. You want to know why? Because they didn’t have the GEHL HA1110 Parts Catalog in front of them. This is not a generic aftermarket printout. It’s a 28-page factory manual printed by GEHL for the HA1110 Hay Attachment. Every exploded view, every reference number, every torque value—it’s all in here. And yes, page 2 tells you the serial number location and defines which side is “right” so you don’t order a left-hand chain when you need a right-hand one. Let’s go through what you’re actually getting.

Decal Locations and Serial Number: Where to Find Them

Pages 2-3 show the decal locations on the main frame. The model and serial number decal sits below the right Quick-switch Yoke, next to the attachment stand. If you’re looking at the unit from behind, facing the direction of travel, the drive chains are on the left. GEHL spells that out so you don’t mix up left and right when ordering parts. The manual also warns: original replacement tires are not sold by GEHL—you buy wheel sets from them and get tires locally. That’s on page 2. Keep that straight or you’ll waste a week waiting for a tire that never ships.

Pickup, Auger, and Drives: What the Exploded Views Show

The main mechanical sections—Pickup (pages 6-9), Auger (pages 10-11), and Drives (pages 12-13)—are broken down into exploded diagrams with part numbers and reference callouts. Each reference number may have a teardrop symbol with a number inside; that number corresponds to a lubricant or oil type listed in the parts list. A hexagon symbol next to a reference number gives the torque value in foot-pounds for that fastener. For example, if you see a hexagon with “60” next to a cap screw, that means 60 ft-lb. The manual tells you that unless otherwise specified, all cap screws or bolts are Grade 5, cadmium or zinc plated, and hex nuts are Grade B. That’s on page 2 and inside the back cover.

Torque Specifications: Inside Back Cover

The torque table lives on the inside back cover of this Parts Catalog. Standard hardware torque values for Grade 5 fasteners, inch-series bolts, and a few metric options are listed there. I can tell you from experience: if you don’t have that table, you’ll either under-torque and get a leak, or over-torque and strip the threads. The inside back cover also includes the abbreviations chart for fastener types—FCS, FHMS, SHCS—so you can decode the parts list without guessing. This is the sort of data you need to keep near the workbench, not buried in a PDF you have to scroll for.

3 Reasons to Use This OEM Manual Instead of Scanning the Internet

First, the part numbers in this GEHL HA1110 Parts Catalog are the actual factory numbers. Aftermarket “equivalents” often use different indexing, which gets you the wrong pickup tine or auger flighting. Second, the exploded views are drawn to scale with correct orientations—you can see exactly how the holddowns and shields fit (pages 14-15). Third, the torque specs are verified by the manufacturer. I’ve seen aftermarket manuals list a torque for a ½-inch bolt that’s 10 ft-lb off. That’s a blown seal or a broken bracket. Spend the money on the factory manual and save the headache.

Accessories Section: Control Boxes and Water Tank Mounts

Pages 16-18 cover accessories: tank completing parts, CB750/760/860/865/1060/1065/1260 control boxes, solenoid housings, and the auger cover kit. The manual treats the control boxes separately—page 17 and 19 have the solenoid housing schematic. If you’re retrofitting a water tank onto a HA1110, the mounting parts are right there on page 20. No need to guess which bracket fits which. These pages also include the alphabetical index (page 21) and numerical index (pages 22-23), so you can cross-reference any part number fast.

Who Needs This Parts Catalog?

If you own a GEHL HA1110 Hay Attachment—whether it’s on a skid steer or a dedicated pull-type—you need this manual. Same if you’re a shop that services these units and doesn’t want to burn billable hours hunting part numbers. The audience is DIY farmers, equipment owners, and home garage enthusiasts who are rebuilding, restoring, or repairing a hay attachment. Beginners can use the exploded views to understand how the pickup drum interacts with the auger without taking everything apart first. Professionals use it to order the exact part from the correct reference number. This manual is for anyone who’s tired of returning wrong parts because the online listing was ambiguous.

Standard Hardware Torque Specifications: What You Get

The inside back cover includes a table for standard hardware torque values in foot-pounds. For a Grade 5 ⅜-inch bolt, the torque range is typically 15-20 ft-lb; for a ½-inch bolt, 35-45 ft-lb. But don’t take my word for it—the manual lists the exact values for each fastener size. The abbreviations table on page 2 tells you what “FCS” or “SHCS” means so you can identify the fastener in the exploded view. This section is short, but it’s the one you’ll flip to most often.

Frequently Asked Questions

Does this manual cover the GEHL HA1110 hay attachment only, or other models?

This is the OEM parts catalog specifically for the GEHL HA1110 Hay Attachment. It does not cover other HA model numbers. If you need a different model, check our related manuals below.

What year or serial number range does this manual apply to?

The manual does not specify a publication year. It replaces form number 903948. The unit serial number is located on a decal on the main frame; the manual applies to whatever HA1110 unit that decal matches. The parts listed are for original GEHL production, so if your machine has been modified, compare the exploded views.

Are torque values given in both foot-pounds and Newton-meters?

No. The manual states torque values in foot-pounds inside hexagon symbols on the exploded views and on the inside back cover table. There is no metric conversion provided. If you need Newton-meters, you’ll have to convert manually (1 ft-lb ≈ 1.356 N·m). That’s a minor inconvenience, but the spec is the spec.

Can I use this parts catalog to rebuild the entire attachment from scratch?

Yes, if you have all the parts and the assembly sequence. The exploded views show each component and its relationship to adjacent parts. The parts list gives you the part number for every nut, bolt, bearing, and shield. However, this is a parts catalog, not a service manual. It won’t walk you through step-by-step disassembly or troubleshooting procedures. For that, you’d want the factory service manual. But for ordering parts and verifying torque, this catalog is what you need.

You’re not going to find a cleaner source of factory parts data for the GEHL HA1110 Hay Attachment than this 28-page catalog. I’ve been wrenching for 28 years, and the difference between using this and a third-party scan is the difference between a bolt that stays tight and one that backs out on the first pass.
