What It Is

This is a complete tune-up kit for Cub Cadet XT1, XT2, and select ZT1 lawn tractors with Kohler 7000 Series engines (KT725–KT745). It includes an oil filter (32 083 09-S), air filter (32 789 02-S), and spark plug—everything needed for an annual oil change and filter service.

Fitment & Compatibility

Engines: Kohler 7000 Series KT725, KT730, KT735, KT740, KT745 (commonly found on Cub Cadet XT1, XT2, LT46, LT50, LT54, ZT1-42, ZT1-54).
Check your engine model (stamped on valve cover or near spark plug)—this kit does not fit Kohler 6000, 8000, or other series.
Deck size doesn’t matter—compatibility is engine-only, not mower deck.
OEM vs aftermarket: This is an aftermarket kit; not genuine Cub Cadet/Kohler parts. Confirm your OEM part numbers (oil filter 32 083 09-S, air filter 32 789 02-S) match.
Measurements: Oil filter thread is 3/4″-16, air filter is a standard rectangular foam/pre-filter combo. Spark plug is a standard 14mm reach with .030″ gap (pre-gapped, but verify).

Key Things to Know

Installation difficulty: Easy (basic tools: wrench for oil filter, socket for spark plug, screwdriver for air filter). Drain oil first.
Common gotcha: The air filter may be slightly tighter than OEM—ensure it seats fully in the housing to avoid unmetered air leaks.
Quality: Oil filter is a standard spin-on; spark plug is a copper-core type (not iridium). Fine for annual changes, but not premium.
What’s not included: Oil, fuel filter, or oil drain plug gasket—buy separately.

Should You Buy It

If you own a Cub Cadet XT1/XT2/ZT1 with a Kohler 7000 Series engine and want a quick, affordable one-box tune-up, this kit works well for routine maintenance. It’s not OEM quality, but for the price and positive reviews, it’s a solid value for DIYers who change oil annually. Skip it if you insist on genuine Kohler parts or have a different engine series.
