Every part on your Kubota RC72-27B tractor mower has a number, and this 31-page parts catalog lists all of them. Coverage runs from the universal joint and bevel gear case through the discharge cover, lift linkage, and accessories. Exploded-view diagrams call out components by name: Yoke PTO, Yoke Quick, Shaft Pinion, Boss Spline, and Comp.Pulley Tension each sit as separate line items. Parts lists cover the mower deck, front and rear gauge wheels, blade holder, and lift arm, so you can pin down the exact component before ordering. The bevel gear section drills down to individual bearing balls and breather plugs. Order the wrong part once and you've spent more than this catalog costs. Bookmarked by assembly, you can jump to the section you need, read off the part number, and call your dealer knowing it's right.

Kubota RC72-27B Common Problems This Manual Covers
Kubota RC72-27B front gauge wheel separated from center sleeve, assembly worn out p. 17
Start with the Front Gauge Wheel exploded view on page 17. The Bush is the primary wear item; order it alongside the Pin Joint and Collar Front Wheel, since all three wear out together across the 72-inch deck's wheel positions. Rear gauge wheel assemblies use the same layout on page 19, with matching Bush and Shaft Front Wheel part numbers.
Manual Section: Front Gauge WheelDrive belt snapped or slipping, can't locate the correct replacement part number p. 13
Open the Tension Pulley exploded view on page 13. The Belt stands alone as a line item in the breakdown. While you're there, note the Comp.Pulley Tension and Spring Tension part numbers too; on a 72-inch deck these three wear together, so ordering them as a set saves a repeat order.
Manual Section: Tension PulleyOnly center blade spins, need gearbox side pulley and driveline part numbers p. 6
Trace the Bevel Gear Case diagram on page 6 for the center gearbox that drives all 3 blade spindles. The Kit Gear Bevel is a single part number bundling the internal gear set, with Shaft Pinion and Bearing Ball listed separately. For the output pulley side, turn to page 9 and find the Boss Spline and Seal Oil in the Pulley Holder breakdown.
Manual Section: Bevel Gear CaseDeck spindle or blade hub seized, need shaft and bearing part numbers p. 11
Find the Blade section on page 11 for the side spindle assemblies. Shaft Blade, Bearing Ball, and Boss Spline each appear as individual line items. For the center spindle, cross-reference the Pulley Holder on page 9, where the Holder Center Pulley carries its own Bearing Ball part number, separate from the 2 outer blade positions.
Manual Section: BladeAnti-scalp rollers cracked or missing, looking for correct part numbers to complete replacement p. 21
Pull up the Discharge Cover parts list on page 21. Roller Anti-Scalp and Pin Gauge Wheel are listed separately. For rollers at the front linkage bracket, cross-reference page 23, where Assy Roll.Anti-Scalp is a complete sub-assembly part number. Identify which of the 4 roller mounting positions is damaged before ordering to avoid duplicate purchases.
