All 30 pages of this Kubota RCK60-30B Parts Catalog PDF zero in on one thing: finding the exact factory part number for your 60-inch mid-mount mower before you waste an afternoon chasing the wrong component. Inside, exploded-view diagrams walk you through every major assembly: universal joint, bevel gear case, blade and pulley hardware, mower deck, gauge wheels, discharge cover, linkage, lift arm, and stopper. Every diagram pairs with a structured parts list carrying OEM reference numbers, quantities, serial number breakpoints, and interchange codes so you know exactly which version fits your machine. The universal joint assembly lists at 3.75 kgf, and the drive belt runs 119 inches: the kind of detail that separates the right part from a costly guess. Quit describing parts to a dealer and hoping they get it right. Bookmarked by assembly, this PDF opens on any device; tap the section, pull the part number, and order with confidence.

Kubota RCK60-30B Common Problems This Manual Covers
Kubota RCK60-30B deck won't engage or slips under load, PTO drive feels weak p. 3
Open the exploded view on page 3 and cross-reference the parts list on page 4 to identify which universal joint components are worn or damaged. The Joint Universal assembly weighs 3.75 kgf — if yours feels lighter or rattles, internal yokes or crosses are likely gone. Pull part numbers from the page 4 list, confirm your serial number range fits, then order OEM replacements.
Manual Section: Universal JointExcessive vibration or loud knocking noise during mowing operation p. 9
Check the Blade exploded view on pages 9-10. A bent or unbalanced blade is the first part to rule out — locate the blade part number on page 10 and verify it matches your deck configuration. Also pull the Tension Pulley parts list on page 11: a worn pulley or idler bracket causes rhythmic knock at deck speed. The Grease Nipple thread size at the blade spindle is M6x1.0 (page 10) — if it's stripped or missing, the spindle has been running dry.
Manual Section: BladeCan't identify the right discharge cover replacement part, unsure which roller fits p. 19
Go to the Discharge Cover exploded view on page 19. The parts list on page 20 breaks out the Cover Discharge, Pin Discharge, Spring Discharge, and Roller Anti-Scalp (size 3.0S). Match each part number to your serial range before ordering — the roller and cover are two separate line items and are often confused. If the discharge pin or spring is missing, the cover flaps loose and accelerates wear on the cover body itself.
Manual Section: Discharge CoverDeck height is inconsistent side to side, lift function doesn't hold position evenly p. 25
Start with the Lift Arm parts diagram on page 25. The Pin Clevis is sized 1/2x1-1/4 (page 26) — a worn or undersized clevis pin lets the arm float. Then check Lift Linkage on page 23: the Bushing Link, Arm Lift 2 Lh, and Shaft Lift are the first components to wear and cause height drift. Pull part numbers for both sides (Lh and Rh are separate SKUs) and compare against the exploded view to confirm nothing is substituted incorrectly.
Manual Section: Lift ArmUneven cut, one side of the deck rides higher, anti-scalp rollers look different left and right p. 21
Compare the Linkage parts diagram on page 21 against your deck. The Roller Anti-Scalp on the linkage side and the one on the Discharge Cover (page 20) are both listed as 3.0S but are separate part numbers in their respective sections. A mix-up between them causes height asymmetry. Also check the Front Gauge Wheel bushing I.D. on page 16: worn bushings (nominal 0.75 I.D.) let the wheel spindle rock and throw off deck level on one side.
Manual Section: LinkageBevel gear case hard to source, unsure which shim thickness to specify when ordering p. 5
Refer to the Bevel Gear Case parts list on page 5. The assembled case weighs 3.82 kgf (page 6) — use this as a quick sanity check on any used unit before buying. The shim at page 6 is listed at 0.2mm; note this is a separate line-item part number, not bundled with the case. Order shims and the case separately, and confirm both part numbers against your serial range in the index before purchasing.
