BISO SRX Parts Catalog

If you’re calling in parts for a BISO SRX straw chopper and you don’t have the part number in front of you, you’re burning time and money. I’ve seen guys order the wrong flail drum bearing because they guessed at the serial number break. This BISO SRX Parts Catalog kills that guesswork. It’s 78 pages of factory part numbers, exploded diagrams, and assembly references. No aftermarket reprints, no generic cross-references. Every reference code like 4U.36.1 points to a specific part on a specific machine. That’s how you keep a chopper running through harvest without downtime.

7 Key Assembly Groups Covered

Open the index on page 1 and you see exactly what’s inside. KNIVES (4U.36.1), V-BELT (4U.36.2), then the main assemblies: BISO-STRAW CHOPPER BASIS FRAME, FLAIL DRUM WITH BEARING, DISTRIBUTOR BOX, DEFLECTOR SHEETS, LAYSHAFT SUPPORT, VEE BELT CLUTCH, and the STRAW WARNING SYSTEM. Each group has its own sub-reference, so you can zero in on the part you need. The catalog also covers KPAB-STRAW CHOPPER variants and conversion kits for V-belt clutches. If you work on SRX machines, this covers the core systems without burying you in irrelevant models.

Does This Catalog Include V-Belt Specs?

Yes. Page 1 lists the V-BELT assembly under reference 4U.36.2. That’s the factory part number for the belt. No generic cross-reference, no “universal fit” garbage. You get the original BISO belt number so you can order exactly what the engineers designed for the SRX. Same goes for the flail drum bearing under 4U.36.52 and the distributor box regulation electric under 4U.36.55. If you’ve ever wasted an afternoon on a belt that was an inch too short, you’ll appreciate this.

KNIVES and V-BELT: Finding the Right Part

Knives take a beating. The catalog lists knife assemblies under 4U.36.1 with exploded views that show how they mount to the drum. You can match the worn part to the diagram and order the correct set. Most shops try to match by eye and end up with knives that don’t align with the counter-knives. This manual prevents that. The V-belt section follows the same logic – belt length, section, and part number are all factory-verified. I’ve seen too many techs slap on a Gates belt from the bin without checking the OEM number. Don’t be that guy.

Factory Source vs. Aftermarket Reprints

The file you get from AutoRepairManuals is a direct scan of the original BISO documentation, not a third-party transcription. Aftermarket parts catalogs often omit serial number breaks or combine incompatible machine years. This one retains the original layout, part number index, and reference codes exactly as BISO printed them. The 78 pages are clean, legible, and organized by assembly group. If you’ve ever tried to use a scanned PDF that’s missing pages or has faded numbers, you know why this matters.

Get the Right Part Number the First Time

When you’re standing at the dealership counter with a broken chopper in the field, you don’t want to call your supplier twice. This catalog gives you the exact part number for every nut, bolt, knife, belt, and bearing. The electrical equipment section (4U.36.69) covers wiring and sensors. The chaff spreader sections (W variants) show different mounting configurations. The conversion kits (4U.36.70-72) let you upgrade the V-belt clutch. You can order everything in one call. That’s the value of OEM documentation.

Frequently Asked Questions

Does this catalog cover the KPAB straw chopper variants?

Yes. Sections 4U.36.78 through 4U.36.101 cover KPAB components, including frames, distributor boxes, and V-belt clutches with specific serial number breaks (+Y 05148, +Y 06440).

Are the part numbers compatible with SRX only?

Correct. Sections marked “FOR TYPE SRX ONLY” (e.g., 4U.36.92-98) are specific to the SRX. Other sections apply to multiple BISO models.

How do I use the reference numbers like 4U.36.1?

Those are BISO’s internal part reference codes. Cross-reference them with the diagrams to identify the exact component. The table of contents lists every code on page 1.

Is this a repair manual or a parts catalog?

Parts catalog. It lists every replaceable component–knives, belts, bearings, frames, clutches, wiring, and chaff spreader parts–with exploded diagrams and factory part numbers. You won’t find step-by-step removal instructions, but you will find the correct OEM part number for anything that wears out or breaks on the BISO SRX straw chopper. For repair procedures, you need a separate service manual. This catalog is intended to be used alongside the service manual to order the right parts before you start the job. Experienced mechanics know that having the part number in hand before you pull the old part saves a trip to the dealer and keeps downtime to a minimum. If you’re rebuilding a flail drum or replacing the distributor box, this catalog ensures you get the correct bearing, seal, and mounting hardware the first time.

Stop wasting time with aftermarket parts lists that don’t match your machine. Access the Factory Manual from AutoRepairManuals and keep it on your tablet or print it out. It’ll save you from ordering the wrong knife set.
