Kubota Garden Tractor Parts

Parts Compatibility for Kubota Garden Tractors

Kubota's garden tractor lineup of the 1990s and early 2000s spanned the T Series, the TG Series, and the G Series. The T1600 was a 13 horsepower garden tractor with a 44 inch deck produced from 1990 to 1996, positioned as a step up from a basic riding mower toward a true garden tractor with a heavier transmission and three point hitch capability on some configurations. The TG1860 and TG1860G followed at 18 horsepower with 48 inch and 54 inch deck options, produced from 1998 to 2003. The G Series (G1800, G1900, G2000) ran in the same era as the early TG and was Kubota's smaller frame garden tractor option, with -S suffix variants indicating spec / region differences from the base machine.

These machines all use small Kubota three cylinder diesel engines from the same families that power the BX sub compact tractors, the F Series front mowers, and the smaller ZD zero turn mowers. That overlap means many service parts for the engine, the fuel system, and the cooling system cross between a TG1860 garden tractor, an F2560E front mower, and a ZD18 zero turn. Deck and chassis service parts are model specific and will not cross outside the garden tractor family.

Common Replacement Parts for Kubota Garden Tractors

Engine oil filters HH150-32430, HH1J0-32430, and 16271-32092 cover the diesel engines used in T, TG, and G Series garden tractors. The in line fuel filter 1258143011 is a high cross fitment service part across the entire small diesel Kubota lineup, and the 12581-43012 variant is its sibling. Oil pressure switch 15531-39010 is a common service item that fits all three series, as is the gear ring 16871-63820 used inside the engine.

Cold weather start service drives orders for the glow plugs 16851-65510 and 1G679-65512 across these older diesel garden tractors, particularly in Canadian operating climates. Thermostat gasket 15676-73270 covers cooling system service, and ignition switch / key 37410-55150 is a recurring service item for these machines. Because these tractors are now 20 to 35 years old in the field, internal engine hardware (studs, gaskets, gear rings) shows up alongside routine filtration in the parts mix.
