Kubota STW34, STW37, STW40 Compact Tractor Parts Manual

The Kubota STW34, STW37, STW40 is a compact tractor series you’ll see on mixed farms, grounds work, and small contractors doing loader and mower work. The Kubota STW34, STW37, STW40 parts manual is what parts desks and mechanics grab when they need to see how the tractor is built, not how to repair it. If you’re trying to name a mystery seal, match a broken casting, or line up everything for a clutch or axle job before you tear it down, this is the right kind of book. If you’re chasing fault codes or torque specs, that’s a different animal.

What this manual helps you do

• Identify every component in the engine, transmission, axles, hydraulics, PTO, 3‑point, steering, and electrical by picture and callout.
• Locate the exact Kubota OEM part number for worn bushings, seals, filters, linkages, and brackets on your STW34, STW37, or STW40.
• Look up quantity-per-tractor for bolts, shims, gaskets, and small hardware so you order everything in one hit instead of making three trips.
• Cross-reference older numbers to newer superseded Kubota numbers using the multiple revisions (BKIDK5079–BKIDK5084) covered by this listing.
• Verify that the parts you’re about to order actually match your tractor’s configuration before you spend dealer money or hunt cheaper aftermarket.

Who this is for

This suits an independent ag mechanic, farm owner-operator, small contractor, or anyone running a few orange tractors and trying to keep parts costs under control. If you need torque values, wiring tests, or step‑by‑step repair procedures, you want the Workshop/Service Manual instead, not this parts catalog.
