Kubota Filter Cross-Reference Chart: Oil, HST & Hydraulic

Thank you for reading this post, don't forget to subscribe!

Quick Answer

Most Kubota tractors have separate filters for engine oil, hydrostatic transmission (HST) and hydraulics, and the part numbers differ by model. Use the tables below to find your tractor, then match the number to your serial range with a dealer if it shows two options. Three things people get wrong: the BX2680 uses HH150-32094, not the HH150-32430 used on other BX models; TC630-93230 and TC630-93220 are air-cleaner elements, not hydraulic filters; and several older numbers (HHK20-36990, HH660-36060, HH150-32430) have been replaced.

Three Filter Systems, Kept Separate

On the HST models we checked (B2601, B2650, L3301, L3901, L4701), dealer maintenance kits and catalogs list the engine oil filter, the transmission (HST) filter and the hydraulic filter as separate parts. Kubota’s B2920 manual also lists them as separate services. We could not find a Kubota statement that every B, L and M tractor works this way, so check your own manual.

How to Read These Tables

Part numbers come from authorized-dealer parts catalogs (Messick’s and Coleman Equipment) for the model named in each row. A catalog entry for one version of a tractor, such as the HST or the HD, is not proof for every version, so the notes say which version we saw. “Replaces” means the catalog says the new number supersedes the old one. It does not mean an aftermarket filter is a match.

BX Series (BX1880, BX2380, BX23S, BX2680)

Model	Engine oil filter	HST filter	Hydraulic filter / notes
BX1880, BX2380	HH150-32430 (earlier) and HH1J0-32430 (later). Kubota’s catalogs split at serial 4NDZ999 / 4NE0001, and dealer pages now show HH1J0-32432 as the newest replacement.	HHK20-36994 (current). Replaces HHK20-36990.	BX2380: K2581-36520, listed as “FILTER,OIL.” We could not confirm it is a cleanable strainer.
BX23S	HH150-32430 (dealer maintenance kit). The serial split was not verified for this model.	HHK20-36994, replacing HHK20-36990.	Not checked
BX2680	HH150-32094, not HH150-32430 (BX2680 and BX2680-1 catalogs and dealer kit).	HHK20-36994, replacing HHK20-36990.	Not checked

B Series (B2301, B2601, B2650)

Model	Engine oil filter	HST filter	Hydraulic filter
B2301	HH150-32094	HH6F0-36060	Not verified
B2601	HH150-32094	HH6F0-36060, replacing HH660-36060	HH6C0-37710 (dealer kit)
B2650	HH150-32094	HH6F0-36060, replacing HH660-36060	HH6C0-37710, replacing HH670-37710 and HH670-37712

L Series (L2501, L3301, L3901, L4701, L5740)

Model	Engine oil filter	HST filter	Hydraulic filter
L2501 HST	HH164-32430	HHK70-14073, replacing HHK70-14070	HH3A0-82623, listed as a hydraulic inlet / suction filter
L3301 / L3901 HST	HH164-32430	HHK70-14073	HH3A0-82623
L4701	HH164-32430	HHTA0-59900, listed by Coleman as the HST high-pressure filter (L4701HST)	HHTA0-37710, listed as the hydraulic oil filter
L5740 HST	HH164-32430	HHTA0-59900 (return line, replacing TA240-59900). The “HST high-pressure” label was not found for this model.	HHTA0-37710 (inlet line, replacing TA040-37710)

Gear-drive (non-HST) versions of the L2501, L3301 and L3901 were not checked. Do not apply the HST filter above to a gear tractor just because the base model name matches.

M Series (M5040, M6040, M7040, M5-111, M6060, M7060, M6-141)

Model	Engine oil filter	Hydraulic filter
M5040	HH1C0-32430 (M5040HD)	Not verified
M6040	HH1C0-32430 (M6040FC)	HHTA0-37710 (M6040FC). M6040HDNB versions also list HH3A0-82623.
M7040	HH1C0-32430	HHTA0-37710 (M7040HD). M7040HDNB also lists HH3A0-82623.
M5-111	HH1C0-32430 (M5-111HDC)	HHTA0-37710
M6060	HH1C0-32430 (M6060HD)	Not verified
M7060	Not confirmed in our latest dealer-catalog check	HHTA0-37710 (M7060HD)
M6-141	HH1G0-32430 (V6108-TIEF4 engine per Kubota’s operator’s manual)	Not verified

HH3A0-82623 and HHTA0-37710 are different parts. A tractor that lists both has two hydraulic filters, not two interchangeable options. Check your model version against the catalog before ordering.

Correction: Air Elements Are Not Hydraulic Filters

Older versions of this chart suggested TC630-93230 and TC630-93220 as possible HST or hydraulic filters for the L4701. Dealer records show they are the outer and inner engine air-cleaner elements. Do not order them for hydraulics.

Superseded Numbers

Old number	Current number	What the catalog says
HH150-32430	HH1J0-32430, now pointing to HH1J0-32432	HH1J0-32430 “replaces” HH150-32430. Both old pages now name HH1J0-32432.
HHK20-36990	HHK20-36994	BX1880, BX2380 (older kits), BX2680-1 and BX23S catalogs.
HH660-36060	HH6F0-36060	B2601 and B2650 HST filter.
HHK70-14070	HHK70-14073	L-series HST filter.
HH670-37710 and HH670-37712	HH6C0-37710	B-series hydraulic filter. The new page also carries an unspecific “superseded” note.
TA240-59900 and TA040-37710	HHTA0-59900 and HHTA0-37710	L5740HST return and inlet line diagrams.

Aftermarket Cross-References We Could Verify

We only list a cross where a manufacturer catalog names the Kubota number or a manufacturer sheet links one aftermarket filter to another. Similar size, or the same engine, is not enough.

Kubota number	Aftermarket filter	Basis
HH150-32430	WIX 51365	WIX application rows say “Use for OE no.: HH150-32430.”
HH150-32430 (indirect)	Donaldson P502067	A Donaldson sheet cross-references P502067 to WIX 51365. It does not name the Kubota number.
HH150-32094	WIX 51064 and WIX 51334	Both list “Use for OE no.: HH150-32094.” They are different filters, so compare before ordering.
HH1C0-32430	WIX WL7135	OEM-qualified entry. The M6040 application has a chassis-number qualifier, so confirm yours.
HH660-36060 (older HST number)	WIX 51361 and WIX WL7143	WIX lists both against HH660-36060. The step to the current HH6F0-36060 comes from the Kubota supersession, not a WIX row.

No Verified Cross Found

We found no manufacturer cross-reference naming HH164-32430, HHK20-36994, HH6F0-36060, HHK70-14073, HH6C0-37710, HH3A0-82623 or HHTA0-37710. That does not prove none exists. Many third-party listings claim compatibility, but a seller’s title is not a catalog cross-reference, so check dimensions and thread against your old filter.

Changing a Filter: The Basics

Match the part number to your row above, and keep the old filter to compare thread and size.
Warm the tractor briefly, shut it off, and drain the matching fluid for the filter you are changing.
Wipe the mounting surface and put a thin film of clean fluid on the new gasket.
Install the new filter and tighten it as the instructions printed on the filter say. Do not use a wrench to over-tighten.
Refill to the level in your operator’s manual, run the tractor, and check for leaks.

Fluid capacities and torque values vary by model. See Kubota Transmission Fluid Change, How to Change Kubota Hydraulic Fluid and Kubota Oil Change Interval.

A Kubota statement that every B, L and M tractor uses three separate filters.

How We Verified This Page

Part numbers, fitment and supersessions were checked against the Messick’s and Coleman Equipment parts catalogs for each named model. Aftermarket crosses were checked against WIX, Donaldson and FRAM catalog pages. The B2920 manual reference comes from a third-party-hosted copy of Kubota’s manual, and its printed page was not verified. Catalogs can change, so confirm with your Kubota dealer using your serial number before a big order.

❓Frequently Asked Questions

QDoes a Kubota tractor have separate oil, HST and hydraulic filters?

On the HST models we checked, yes. Dealer kits for the B2601, B2650 and L3901 list them as separate parts. We could not confirm it for every Kubota model, so check your own manual.

QWhat oil filter does a Kubota BX2680 use?

Dealer catalogs and the BX2680 kit list HH150-32094. The BX1880, BX2380 and BX23S list HH150-32430 or its replacement HH1J0-32430.

QIs TC630-93230 a hydraulic filter?

No. Dealer records list TC630-93230 and TC630-93220 as engine air-cleaner elements.

QCan I use an aftermarket HST filter?

WIX lists 51361 and WL7143 against the older HH660-36060, which Kubota replaced with HH6F0-36060. We found no manufacturer cross naming the current number, so compare the filter against your old one. For the BX, L-series and other HST filters we found no verified aftermarket cross.

QWill using a non-Kubota filter void my warranty?

We are not lawyers. Warranty terms are in your owner’s paperwork, so read them and ask your dealer. Keep receipts and records of every service either way.

QMy model is not listed. What should I do?

Look up your model and serial number in a Kubota dealer parts catalog, or compare the part number on your existing filter. Do not assume a neighboring model uses the same number.
