A 2290 is a Kubota 22hp.Gas lawn tractor.It has a Kawasaki engine.42 inch deck.Should I say more
I'm assuming your talking about the T2290
I am pointing this out because with Kubota you can't use just the number as there are may different series that use the same number with different letters in front of and behind the numbers which change everything drastically.
Do you know which T2290 you have?
T2290KW-42
or
T2290KWT-48
And I realize that this has no bearing on your original question, but for future use and info it might matter!
