Kubota RA2590 HYDRO Rotary Rake Parts Manual

The Kubota RA2590 HYDRO is a rotary rake you’ll see behind mid‑size tractors, usually on hay ground where clean windrows matter. The Kubota RA2590 HYDRO parts manual is what the parts desk and folks like me (I wrench on my own BX and L3901) use when something bends, breaks, or wears out. You’d reach for this when you’re trying to ID a tine arm, hub bearing, hydraulic motor fitting, or any of the hardware before you order parts or tear the rake apart.

What this manual helps you do

• Identify every component on the RA2590 HYDRO from exploded diagrams so you know exactly which arm, guard, or bracket you’re looking at.
• Locate the correct OEM Kubota part number for tines, tine arms, wheels, gearboxes, hydraulic components, and frame pieces before calling the dealer.
• Look up how many of each fastener, seal, or bushing the machine uses so you can order everything for the job in one shot.
• Cross-reference older part numbers to the newer superseded Kubota numbers shown in the catalog so you don’t get told “that number’s obsolete” at the counter.
• Verify that the parts you already have on the bench actually match what belongs on the RA2590 HYDRO before you button the rake back up.

Who this is for

This fits a farm owner‑operator, independent ag mechanic, or Kubota parts person who already knows how to wrench and just needs the right numbers and diagrams. If you’re after torque specs, repair procedures, or hydraulic troubleshooting, you want the Workshop/Service Manual, not this parts manual.

FAQ

Q: Does this cover the hydraulics, rake rotor, and running gear assemblies?

A: Yes, a Kubota RA2590 HYDRO parts manual typically shows exploded views and part lists for the hydraulic components, rotors, wheels, and main frame.

Q: Are the part numbers in here current?

A: The manual shows the OEM part numbers used at the time and usually notes superseded numbers, but your Kubota dealer can confirm the latest number in their system.

Bottom line: If you already know how to fix the rake and just need diagrams and Kubota numbers for the RA2590 HYDRO, this is the right book; if you need “how-to” instructions, keep looking for the service manual instead.
