Kubota PH3300-3350-3400-3450 Power Harrow Parts Manual

Kubota’s PH3300-3350-3400-3450 is a PTO-driven power harrow you’ll see hanging off the back of a mid-size tractor in row crops or seedbed prep. The Kubota PH3300-3350-3400-3450 parts manual is what I keep on the bench when I’m trying to sort out tines, bearings, seals, and hardware before the next weather window. People grab this book when they want to ID a broken piece, see how an assembly stacks together, or send a clean parts list to their Kubota dealer so the machine is ready for the next job.

What this manual helps you do

• Identify every wear part on the power harrow—tines, tine holders, side panels, guards, and skids—by OEM Kubota part number.
• Locate bearings, seals, shims, and hardware in the gearbox and rotor assemblies using exploded diagrams so you don’t miss a small but critical part.
• Look up quantity-per-machine for bolts, nuts, and gaskets to build accurate pick lists for overhauls or preseason refreshes.
• Cross-reference older part numbers to the superseded Kubota numbers shown in the illustrations and parts lists before you order.
• Verify that the parts your dealer quotes match the exact PH3300, PH3350, PH3400, or PH3450 configuration you’re running in your fleet.

Who this is for

This parts manual fits how a farm owner-operator, fleet maintenance manager, Kubota dealer parts counter, or independent ag mechanic actually works. If you’re after torque specs, PTO setup procedures, or repair steps, you don’t want this book—you want the Workshop/Service Manual, not the parts catalog.

FAQ

Q: Does this manual cover the gearbox, rotors, PTO shaft, and 3-point hitch frame assemblies?

A: Yes, a Kubota parts manual like this normally shows exploded views and part numbers for the gearbox, rotor sections, PTO driveline, and main frame/hitch components.

Q: Are the part numbers in this manual the latest ones from Kubota?

A: The manual shows the OEM numbers used at print time and usually notes superseded numbers, but your Kubota dealer will confirm any newer replacements in their system.

Bottom line: If you need to see every component on a PH3300-3350-3400-3450 and build accurate parts orders, this is the right manual; if you need how-to repair instructions, keep looking for the WSM.
