Finding the correct OEM part number shouldn't mean a wasted trip to the dealer. This Kubota L4610DT-HST catalog runs 342 pages of exploded views paired with numbered parts lists, covering every major assembly: engine internals, the HST transmission, front axle, hydraulic system, and cab hardware. Numbers are cross-referenced for both old-type and new-type variants, with separate breakdowns for the HST unit, governor, brake assembly, and hydraulic outlet block. Factory weights sit beside each listing, so you can plan shipping before you order: crankcase assembly at 49 kgf, flywheel at 29.8 kgf, cylinder head at 19.1 kgf. A wrong part on the bench is money out of your pocket. Everything is bookmarked by system and keyword-searchable, so your phone or tablet lands on the right assembly the moment you need it.

Kubota L4610DT-HST Common Problems This Manual Covers
Hydrostatic drive loses movement and creeps weakly when you push the forward pedal p. 120
Check the exploded view on page 120 to pin down the hydrostatic transmission components, then match the filter part numbers to your serial number. Swapping the whole mid case means handling 34 kgf, so factor that into shipping.
Manual Section: Mid Case [Hst Type]Oil leakage spotted around the engine block base and front gear case p. 6
Inspect the engine diagram on page 6 for the right plug and cap sealing identifiers, and cross-reference the wear pins and gaskets against your serial range. The full crankcase assembly runs 49 kgf, so budget for the freight.
Manual Section: CrankcaseFront axle engagement grinds and fails to lock into four wheel drive mode p. 174
Review the chassis diagram on page 174 to locate the front axle frame components, then match the engagement linkage and bearing numbers to your cab variant. A complete rear axle assembly, by contrast, weighs 11 kgf.
Manual Section: Front Axle FrameOperator seat cushion is torn and the suspension base bottoms out over rough terrain p. 274
Confirm the seat component part numbers on page 274 before you order, and check the applicability notes so the hinge and suspension assemblies fit your ROPS variant. The complete seat assembly weighs 9.6 kgf.
Manual Section: Seat [Rops Type]Frequently Asked Questions
What transmission does the Kubota L4610DT-HST use?
The L4610DT-HST runs a Hydrostatic Transmission, which the model name itself makes clear. The parts book backs this up with dedicated sections such as "HST [COMPONENT PARTS] [HST TYPE]" on page 122.
How do I find Kubota L4610 parts by serial number?
Start with the "S.No." column in the parts list. When an entry shows ">=", your equipment's serial number needs to be greater than or equal to the number listed. When it shows "<=", your serial number should fall at or below the number shown.
What are the replacement specifications for hydrostatic transmission filters?
Two filters appear in the book. The "CARTRIDGE OIL FILTER" (Part No. T0070-37710) sits in the "HYDRAULIC OIL LINE(INLET) [HST TYPE]" section on page 207 at 0.725 kgf (1.595 lb). A "FILTER OIL" (Part No. TA240-59900) shows up in the "OIL COOLER [HST TYPE]" section on page 218 at 0.955 kgf (2.101 lb). Replacement procedures and torque specs, though, aren't included in this parts manual.
What are the replacement specifications for seals and gaskets?
For seals and gaskets, the book gives part numbers and weights. One example: the "GASKET CYLINDER HEAD" (Part No. 19077-03310) at 0.13 kgf (0.286 lb) on page 54. What it doesn't include is replacement procedures or torque specs for those parts.
How quickly can I access this Kubota L4610DT-HST manual after buying?
The 342-page searchable PDF downloads the moment checkout clears. Open it on a laptop, tablet, or phone and take it straight to the shop floor.
Are there any print restrictions on this Kubota L4610DT-HST manual?
Yes. Print as many copies as you like; there are no restrictions. Plenty of mechanics run off only the section they need for the job at hand.
