Kubota BV4580 Variable Chamber Round Baler Parts Manual

The Kubota BV4580 is a variable chamber round baler, the kind you’ll see behind a mid-size tractor doing hay all day. The Kubota BV4580 parts manual is what parts counters, farm owners, and independent mechanics grab when they’re trying to pin down the exact roller, chain, pickup tooth, or shield that failed. Folks usually use this to identify what broke, see how it fits in the assembly, and get the right Kubota number before they order or tear things apart.

What this manual helps you do

• Identify every component in the baler—pickup, chamber, belts, net system, driveline, and guards—using exploded diagrams and callouts.
• Locate the correct OEM Kubota part number for worn chains, sprockets, bearings, rollers, belts, and hardware on the BV4580.
• Look up quantity-per-machine for bolts, nuts, spacers, seals, and small bits so you can order everything in one shot and avoid repeat trips.
• Cross-reference older part numbers to the updated Kubota numbers shown in the catalog when parts have been superseded.
• Verify that a part you’re about to order actually matches your BV4580’s configuration by comparing the illustrated assembly to what’s on your baler.

Who this is for

This Kubota BV4580 parts manual is aimed at an independent ag mechanic, farm owner-operator, Kubota dealer parts staff, or anyone maintaining a small hay fleet. If you’re looking for torque specs, timing or adjustment procedures, or “how-to” repair steps, you need the Workshop/Service Manual instead, not this parts book.

FAQ

Bottom line: If your main goal is to identify and order the correct Kubota BV4580 baler parts using diagrams and OEM numbers, this is the right manual; if you want repair procedures, keep looking for the service manual instead.
