One rotary tiller, mapped part by part: this Kubota FL850 Parts Catalog breaks down every assembly across 18 pages so you order the right component the first time. Seven illustrated sections cover the Gear Case, Rotary Support, Chain Case, Blade Shaft, Rotary Cover, Skid, and Joint groups. Each pairs an exploded view with a parts list carrying ref numbers, part numbers, quantities, serial-number applicability, and interchangeability codes. Looking for the 574 LH or RH blade number? The BEVEL 36 gear, a chain case sprocket, or the tightener bolt? They're listed, right down to individual circlips and seal washers. Factory weights are included too: 10.8 kgf for the rear cover assembly, 18 kgf for the blade shaft assembly, useful for confirming you've matched the correct sub-assembly. Section bookmarks drop you straight onto Blade Shaft or Chain Case. Pull up the part number before you call your dealer.

Kubota FL850 Common Problems This Manual Covers
Yoke snapped at the hitch connection and you're not sure which part number covers the full joint assembly p. 17
Check the Joint section exploded view starting page 16. Page 17 lists JOINT 1 (part #70710-61310) at 1.63 kgf (3.586 lb) as the full shaft assembly; the standalone YOKE shows separately at 0.66 kgf (1.452 lb). Compare both line items before ordering to confirm whether you need one component or both.
Manual Section: JointRear rock shield bent after hitting debris, unsure whether to order the full cover assembly or the hinge separately p. 13
Open the Rotary Cover diagram at page 12. The ASSY REAR COVER (part #70710-55300) is listed on page 13 as a complete unit at 10.8 kgf (23.76 lb). Confirm in the exploded view whether the hinge and shield are separate line items or bundled into the assembly number before you order.
Manual Section: Rotary CoverChain case sprockets look worn and you can't tell which part numbers match the right tooth count p. 9
Start with the Chain Case diagram at page 8. Page 9 lists two distinct sprockets, SPROCKET 11 at 0.235 kgf (0.517 lb) and SPROCKET 16 (part #70710-53430) at 0.44 kgf (0.968 lb), plus CHAIN (part #70710-53410) at 2.15 kgf (4.73 lb). Cross-reference each part's position in the exploded view against your unit to confirm tooth count first.
Manual Section: Chain CaseBlade shaft bent or seized, and you can't confirm whether to order the full assembly or just the bushings p. 11
Turn to the Blade Shaft diagram at page 10. Page 11 lists ASSY SHAFT,BLADE (part #70710-54340) as a complete unit at 18 kgf (39.6 lb), with BUSH,BLADE SHAFT listed separately at 0.096 kgf (0.2112 lb). Check the exploded view to see whether the bushing is part of the assembly number or a line item of its own.
Manual Section: Blade ShaftGear case leaking oil, and you need the correct seal type plus matching bearing part numbers p. 5
Pull up the Gear Case parts list on page 5. Two ball bearings appear: type 6305 at 0.23 kgf (0.506 lb) and type 6206 at 0.196 kgf (0.4312 lb). The oil seal is spec'd TC25*47*8 at 0.014 kgf (0.0308 lb). Match each to its position in the page 4 exploded view before ordering, since bearing location determines the type.
Manual Section: Gear CaseDepth skids worn through, and you can't locate the right part number for replacement skid components p. 15
Go to the Skid section at page 14. The page 15 parts list includes MAST,TOP (part #70710-56420) at 2.1 kgf (4.62 lb) as a primary skid component. Compare the page 14 exploded view to tell whether the worn piece is the mast assembly or a separate skid shoe listed on its own line.
