Kubota RT140 Rotary Tiller Parts Manual (BKIDK5246)

The Kubota RT140 is a 3‑point rotary tiller that usually lives on the back of a compact or small utility tractor. The Kubota RT140 parts manual is what I reach for when a farmer brings in a bent flange, a leaky seal, or a box of mystery hardware from the tiller. Buyers are usually trying to figure out exactly which tines, seals, bearings, or shields they’ve got so they can order the right pieces before planting time. This book, BKIDK5246, is only a parts manual, not a repair guide.

What this manual helps you do

• Identify the exact OEM Kubota part number for RT140 tines, tine holders, flanges, side covers, and shields before you order anything.
• Locate seals, bearings, and gaskets in the gearbox and side drives so you don’t miss a small but critical part in a reseal job.
• Look up the correct quantity of bolts, nuts, and washers when you’re putting the tiller back together after replacing tines or a bent rotor section.
• Cross-reference older RT140 part numbers to the newer superseded Kubota numbers most dealers now stock.
• Verify that the parts your dealer or online source is offering actually match the RT140 illustrated assemblies in this Kubota parts manual.

Who this is for

This fits an independent ag mechanic, farm owner-operator, dealer parts counter, or small contractor trying to keep an RT140 tiller working without guesswork. If you need torque specs, gearbox setup steps, or adjustment procedures, you want the Kubota workshop/service manual, not this parts catalog.

Bottom line: If you’re trying to identify and order the right Kubota RT140 rotary tiller parts, this BKIDK5246 parts manual is what you want; if you’re trying to learn how to repair or adjust the tiller, keep looking for the service/workshop manual instead.
