Deutz Fahr HMW 1124 Parts Catalog

If you’ve ever ordered a part for your HMW 1124 and ended up with the wrong V-belt or a cutter bar that doesn’t fit, you know the headache. I’ve seen guys waste a whole afternoon because they trusted a sketchy aftermarket parts diagram. This OEM catalog from Deutz Fahr HMW 1124 Parts Catalog puts the factory exploded views and part numbers right in front of you. No guessing. No cross-referencing with a worn-out part that’s been filed down. You get the exact reference numbers for every bolt, bearing, and chain on the cutting table and feeding elevator.

Cutting Table and Feeding Elevator: What’s Covered

This 75-page catalog breaks down the entire cutting table assembly and the feeding elevator into manageable sub-sections. You’ll find the table trolley, the cutting table chassis, the main drive with sliding sleeve, and the P.T.O. shaft driveline. The section on the table trolley includes a safety label diagram (4P.30.1) – I’ve seen too many guys skip safety labels because they think they know the machine. Don’t. The catalog gives you the exact part numbers for the labels so you can replace them if they’re worn off.

Table Trolley Safety Labels – Don’t Skip Them

Go to page 4P.30.1 and you’ll see the safety label for the cutting table and table trolley. That’s not just a sticker – it’s a legal requirement and a safety warning. If that label is missing or illegible, you need to replace it. This catalog gives you the OEM part number so you order the right one. I’ve seen aftermarket replacements that are the wrong size or fade in a season. Factory label or nothing.

Does This Catalog Include the Reel Hydraulics?

Yes, and it covers both vertical and horizontal adjustment cylinders. The reel hydraulics section (4P.34.1 through 4P.34.5) shows the hydraulic cylinder for vertical adjustment at the left and right, plus the horizontal cylinder. If you’re rebuilding a reel that’s sagging or not adjusting evenly, you need those part numbers. The catalog lists the seals, the rod, and the cylinder body. You won’t find that level of detail in a generic parts list.

3 Key Drivetrain Subsystems

The drivetrain on this HMW 1124 is broken into three main sub-sections: the main drive with sliding sleeve, the main drive with P.T.O. shaft, and the gearbox knife drive. Each one has its own exploded view on pages like 4P.31.1, 4P.31.2, and 4P.31.11. The gearbox knife drive is split by serial number ranges – 5.40 m to 7.20 m. If you’ve got a machine in the 29108 to 30567 range, you need the parts listed on 4P.31.12. Miss that detail and you’ll order the wrong gearbox components. The catalog saves you that mistake.

V-Belts, Chains, and PTO Shafts – Exact OEM Specs

Under the cutting table section you’ll find V-belts and chains on 4P.31.1. The catalog shows the belt lengths and cross-sections as OEM part numbers. Same for the wide-angle P.T.O. shafts – there are two manufacturers listed: “WS” and “BYPY”. Each has its own page (4P.31.7 and 4P.31.8). If you try to use a generic P.T.O. shaft, you’ll run into fitment issues with the spline or length. This catalog tells you which manufacturer’s shaft you have and which parts to order.

For the cutter bar, the catalog lists multiple variants based on length and serial number. Page 4P.31.16 covers the cutter bar for machines up to serial 33024 with 3.00 m to 4.80 m cutting width. Page 4P.31.18 covers 5.40 m to 7.20 m versions. The knife guard assembly is on 4P.31.21. If you need just the guards, you don’t have to buy the whole bar – the catalog gives you the individual guard part number.

Intake auger driving parts and friction clutch are on 4P.31.28 and 4P.31.30. The friction clutch is a common failure point when the auger jams. The catalog shows the clutch plates, springs, and hub. Order the OEM parts and you’ll avoid the cheap aftermarket clutches that slip after a few hours.

Now, about source authenticity. This is a direct OEM reproduction from Deutz Fahr. Not a third-party scan. Not a reprint that loses resolution on the exploded views. Every page is clear, every part number is legible. I’ve compared this to the aftermarket catalogs that claim to cover the HMW 1124 – they miss sub-sections like the reel support or the divider (long and short). The OEM catalog includes the long divider on 4P.32.1 and the short divider on 4P.32.2. If you’re missing a divider, you need the exact part. You can’t fabricate it from a generic drawing.

If you work on the older FAHR HD 300, check the FAHR HD 300 Parts List for similar coverage. For other cutting table models, the Deutz Fahr Raps Parts Catalog (Cutting Table) goes deeper into the reel and divider systems. And if you need the full index for the M2680 series, the Deutz Fahr M2680 Parts Catalog Index is a good companion document.

For a broader understanding of why OEM documentation matters in the Automotive Industry Overview, you can read about the standards that keep parts interchangeable. The same principles apply to agricultural machinery – the Automotive Industry Overview explains why manufacturer specs are critical for safety and fit.

Frequently Asked Questions

Is this the same as a repair manual?

No. This is a parts catalog. It shows exploded views and part numbers, not repair procedures. You need a separate service manual for torque specs and disassembly steps. This catalog is for ordering the correct parts.

How do I find the part number for the reel bearing (serial 36052)?

Go to page 4P.33.2 – the reel bearing section. The catalog lists the bearing as a separate part with its own OEM number. Cross-reference with your serial number and order directly. The bearing is not a generic size; it’s specific to the reel support.

I’ve been turning wrenches since before most of you were born, and I can tell you: the only way to keep a Deutz Fahr HMW 1124 in the field is to use the right parts.
