Part of the Kubota Parts Manuals.
This Kubota Parts Catalog covers the B7400HSD compact tractor and lists the factory part numbers for the entire machine across 323 pages. Every assembly is shown as an exploded diagram paired with a parts list giving the reference number, Kubota part number, quantity, and the serial number range each part fits.Use it to identify and order the exact replacement parts for the engine, fuel and cooling systems, clutch, transmission and rear axle, hydrostatic transmission, hydraulics, steering, and electrical components. Because parts often change across serial number ranges, the catalog's serial number and interchangeability columns let you confirm a part fits your tractor before you buy. It is the reference for anyone rebuilding or maintaining a B7400HSD who needs the correct part numbers the first time.

Kubota B7400HSD Common Problems This Manual Covers
Hydrostatic drive performance loss
Weak forward or reverse movement and slow response are recurring HST complaints, especially when service intervals are missed. The HST section gives the exploded view and part numbers for the hydrostatic unit.
Manual Section: HST [Hst Type] p. 145Weak or slow three-point hitch and hydraulics
Hydraulic functions that lift slowly or drop off often trace to worn pump components or internal leakage. The hydraulic pump section identifies the pump and its component parts for replacement.
Manual Section: Hydraulic Pump p. 64Hard starting or no crank
A tractor that cranks slowly or not at all usually needs starter or battery work. The starter section lists the assembly and its component parts so you can order the right pieces.
Manual Section: Starter p. 101Overheating from a failing radiator
Overheating can follow a damaged or clogged radiator and worn cooling hoses. The radiator section gives the exploded diagram and part numbers for the cooling package.
Manual Section: Radiator [Except[Au]] p. 91Clutch wear on gear-drive work
Clutch wear shows up as slipping or difficulty transferring power. The clutch section identifies the disc, cover, and related hardware for a clutch job.
Manual Section: Clutch p. 30Routine filter replacement
Owners most often shop for filters and routine service parts rather than major internals. The oil filter section shows the engine oil filter and its part number for scheduled changes.
Manual Section: Oil Filter p. 16Frequently Asked Questions
