This 25-page Parts Catalog has one purpose: matching you to the exact part number before checkout. It carries exploded assembly views for every component group on the RCB60-I mower deck, from universal joints and grease nipples to PTO flanges (the FP82-A variant included), front PTO cases and belt runs, the gear box with bevel pinion detail, spindle and blade holders, deck and front wheel assemblies, rear wheel arms and rollers, and the complete main stay linkage. Component weights sit beside each part number, so the 6.6 kgf front PTO case and 1.73 kgf joint assembly are easy to verify before you buy. Pull the number up on your phone, check the cross-reference, and order once. Bookmarks drop you into any assembly group in a single click.

Kubota RCB60-I Common Problems This Manual Covers
Kubota RCB60-I deck drive belt needs replacement after storage, can't confirm correct part number before ordering p. 10
Check the Front PTO exploded view on page 10 to trace the full belt routing, then find BELT 40 listed as part number 70722-32430 (0.175 kgf) on page 11. Verify PULLEY 117 (part #70722-32370) shows no damage in that same diagram before ordering only the belt. If your unit carries the Fp82-A PTO configuration, cross-reference pages 13-14 for the alternate belt part number instead.
Manual Section: Front PTOBlade worn or chipped after long service, need correct cutter and spindle part numbers before ordering p. 17
Open the Spindle and Blade parts diagram on page 17 and locate your cutter shaft and blade positions in the exploded view. Match each one to the parts list on page 18, which lists HOLDER, PULLEY 1 at part number 70722-34110 (2.6 kgf). If the spindle shows play, note the retainer and bearing part numbers from that same list so the full assembly ships together.
Manual Section: Spindle and BladeFront anti-scalp wheel missing or cracked, cannot identify correct replacement part number p. 20
Turn to the Deck and Front Wheel section on page 20, where the exploded view breaks out the wheel, shaft, bearing, and cap as separate line items. WHEEL, FRONT appears on page 21 as part number 70722-42110 (1.9 kgf). If the shaft housing shows wear, note the bearing and cap part numbers from that same list, or you risk ordering the wheel and finding the bearing gone too.
Manual Section: Deck and Front WheelDeck lift linkage bent or seized, need lift link and front stay part numbers for both sides p. 24
Start with the Main Stay parts diagram on page 24, which separates LH and RH front stays, lift link, guide, and holder into individual components. STAY, LH FRONT is part number 70722-51110 (4.2 kgf) on page 25. Pin down whether the damage is left-side, right-side, or the lift link itself before ordering, since all three are distinct line items with separate part numbers.
Manual Section: Main StayRear deck wheel or roller arm damaged, need rear wheel assembly part numbers to restore deck height control p. 22
Pull up the Rear Wheel diagram on page 22, where the arm, bracket, rear wheel, shaft, lever, stay, and roller appear as separate components. Find each worn part, note its index number, and match it to the parts list for the exact part numbers. If the arm geometry looks bent, order the stay and bracket along with the wheel, since mismatched components throw off deck height across the cutting width.
Manual Section: Rear WheelPTO driveshaft joint worn or binding, need universal joint and cross assembly part numbers p. 4
Check the Joint exploded view on page 4 against the parts list on page 5, where JOINT 1 is part number 70722-31110 (1.73 kgf). The diagram also breaks out the Assy Joint Cross, Grease Nipple, and Snap Ring as separate line items. Spot every worn component before ordering so the whole joint assembly goes in one order, not a return trip for the snap ring or nipple.
