Kubota Model Numbers Explained

Kubota's range spans compact tractors, construction machinery and engines. Model codes follow logical patterns once you identify the product family.

Compact Excavators — K / U / KX / U-Series

Kubota has been a pioneer of the compact excavator and holds consistent naming conventions:

K-Series — earliest / smallest compact excavators (K008, K015)
KX-Series — conventional tail-swing compact excavators (KX016, KX019, KX027, KX037, KX057, KX080)
U-Series — ultra-tight-tail or zero-tail-swing excavators (U17, U25, U27, U35, U48, U55)

The number usually indicates operating weight in 100kg (KX080 ≈ 8t, U55 ≈ 5.5t).

Compact and Utility Tractors

Kubota tractors are grouped by size class:

B-Series — Sub-compact (B1181, B2261, B2301, B2420, B2650, B3150)
L-Series — Compact utility (L3901, L4060, L5040, L5240, L6060)
M-Series — Utility and mid-size (M4, M5, M6, M7, M8) — the number generally indicates HP × 10
MGX / M-GX — Premium mid-size with cab (MGX 110, 130, 150)
M7 — Large-frame utility (M7-132, M7-152, M7-172)

Common tractor suffixes:

HD — Heavy duty
Premium — High-spec trim
HST — Hydrostatic transmission
DT — Dual traction (4WD)

Skid Steers and Compact Track Loaders

SSV-Series — Skid steer loader (SSV65, SSV75)
SVL-Series — Compact track loader (SVL65, SVL75, SVL95)

Compact Wheel Loaders

R-Series — R065, R075, R085, R630, R430, R540 (legacy / newer ranges)

Utility Vehicles

RTV-Series — Rough-terrain vehicle (RTV-X900, RTV-X1100, RTV-XG850)

Engine Codes

Kubota engines power a vast number of other OEMs' equipment (Bobcat, Takeuchi, Yanmar-alternatives, Toro, and many more). Codes follow this pattern:

D — naturally-aspirated indirect-injection diesel (D905, D1105, D1305, D1503, D1703)
DI — direct-injection (D1703-DI)
V — V-configuration or larger inline (V1505, V2003, V2403, V2607, V3300, V3800)
F — small engines (F300, F600)

So a V2403-M-DI-T is a V2403-family engine (2.4L), modified, direct-injection, turbo.

Finding Your Serial Number

Excavators — data plate on the right side of the upper structure; stamping on the boom pivot frame
Tractors — plate on the dashboard, stamping on the transmission case, VIN on the right-hand chassis rail
Skid steers / CTLs — plate inside the cab, rear bulkhead
Engines — stamped on the block, usually on the rear right side
