Every assembly on your B1700D, B2100D, or B2400D compact tractor mapped to its factory part number across 261 pages. Exploded views cover 125 parts-list assemblies, with hydraulic breakdowns of the pump, control valve, steering controller, and flow divider, plus drivetrain diagrams from clutch shaft through rear differential and front axle case. Crankcase, oil pan, cylinder head, injection pump, governor, nozzle holder, dynamo, starter, panel board, transmission case, brake, ROPS, and wheel options from 6-12 fronts to 31x15.5-15 rears are all here. Need a +0.50mm oversize piston or the -0.40mm undersize crankpin metal? Reference numbers are right there. Panel board diagrams sit alongside the 30A main fuse and 5A auto fuse callouts. Stop ordering the wrong bushing twice. Bookmarked by system: tap the assembly, read the Ref.No, order the right part the first time.

Kubota B1700D, B2100D, B2400D Common Problems This Manual Covers
Rear brake disc and lining part numbers hard to identify when ordering a replacement set p. 151
Open the Brake exploded view on page 151. Match your serial number range to the brake disc and lining callouts, then cross-reference the parts number list. Order discs and linings as a matched set per side, and verify the 30A main fuse circuit on page 113 is unrelated before assuming a parts mismatch.
Manual Section: BrakeFront axle bevel gear and shim part numbers unclear when rebuilding a 4WD case with backlash issues p. 175
Pull the Bevel Gear Case diagram on page 175 and the Front Axle Case view on page 177. Identify the bevel gear set, bearings, and shim pack by callout number. Confirm the 11-20T front differential bevel gear teeth count on page 174 matches your assembly before ordering shims and bearings as a kit.
Manual Section: Bevel Gear CaseHydraulic pump component parts and seal kit numbers confusing when sourcing rebuild parts for a weak lift p. 68
Reference the Hydraulic Pump Component Parts exploded view on page 68. Identify the pump body, gears, and seal callouts, then list each part number from the parts list. Check the suction line components on pages 203 to 206, since a clogged suction screen often masks as a pump parts problem.
Manual Section: Hydraulic Pump [Component Parts]3-point hitch lift rod, lower link, and top link parts missing or mismatched on a used tractor p. 222
Work from the Lift Rod view on page 222, Lower Link on page 224, and Top Link on page 226 to identify each pin, bushing, and link by callout. Verify Category 1 hitch dimensions against your implement before ordering. Review the Control Valve component parts on page 218 if drift symptoms accompany missing hardware.
Manual Section: Lift RodFuel filter element and bowl assembly part numbers unclear when ordering a replacement for hard starting p. 88
Pull up the Fuel Filter Component Parts diagram on pages 88 to 89. Identify the filter element, bowl, O-ring, and bracket by callout number. Cross-reference the Fuel Pipe layout on page 84 to confirm inlet and outlet fitting sizes match before ordering, since suffix variants between B1700D, B2100D, and B2400D differ.
Manual Section: Fuel Filter [Component Parts]Starter relay kit and glow plug part numbers hard to find when diagnosing cold-start failures p. 260
Compare the Starter Relay Kit option diagram on page 260 against the Nozzle Holder and Glow Plug section on page 39. Identify the relay, harness, and glow plug callouts. Verify against the Battery layout on page 100 and confirm the 30A main fuse on page 113 matches your panel before ordering the relay kit.
Manual Section: Stater Relay Kit [Option]Frequently Asked Questions

How will I receive this Kubota B1700D, B2100D, B2400D Parts Catalog?
A 261-page searchable PDF, ready for instant download. Open it on any device, including your phone while you're under the hood. No shipping, no waiting.
Are there any print restrictions on this Kubota B1700D, B2100D, B2400D manual?
None. No DRM, no copy protection. Print the whole catalog or just the pages you need on any home or office printer.
Does this Kubota B1700D, B2100D, B2400D manual cover the hydraulic system?
This is a parts catalog, so it shows exploded parts diagrams rather than circuit schematics. It includes detailed exploded views of the hydraulic components — pump, control valve, cylinder, and oil lines — with OEM part numbers, not wiring-style circuit diagrams.
Document Quality
This is a scanned parts manual, but it has been processed with OCR, so you can search the full text and copy part numbers. The text in the parts lists is clear and easy to read, while the scanned diagrams are raster images that can appear slightly pixelated when zoomed in. Most labels and reference numbers on the diagrams are legible, and the pages are generally clean with only minor scan artifacts.
