Cub Cadet uses different oil filters depending on your machine's engine size and model year
Cub Cadet equipment — whether a lawn mower, garden tractor, or compact tractor — does not use a single universal oil filter. The filter you need depends on which Cub Cadet model you own and what engine powers it. Most Cub Cadet mowers and small tractors use spin-on filters (the cylindrical kind you twist off and on), but the thread size, height, and flow rating vary. Some older or smaller models use cartridge filters instead, which slide straight out without threading.
The fastest way to find your filter is to check your owner's manual or the parts diagram for your specific model number. If you have lost the manual, Cub Cadet's website has a parts lookup tool where you enter your model number and see the exact filter part number. You can also call a Cub Cadet dealer with your model number and they will tell you the filter in under a minute.
Key Takeaways
- Your model number, not just "Cub Cadet," determines which filter fits — check your manual or the parts diagram for the correct part number.
- Most Cub Cadet mowers and tractors use spin-on filters, but some older models use cartridge filters that pull straight out.
- A Cub Cadet dealer or the manufacturer's parts lookup tool will match your model to the right filter in minutes.
- Aftermarket filters from Fram, Kohler, or Briggs & Stratton often work in Cub Cadet machines if they match the thread size and flow rating, and usually cost less than OEM parts.
How to locate your model number and find the correct filter
Your Cub Cadet model number is stamped or printed on a metal plate, usually on the frame near the engine or under the seat. Write down the full number — it often looks like "XT1 LT42" or "LT1050" — and keep it handy. This number is the key to finding everything you need about your machine, including the oil filter.
Once you have the model number, go to partscatalog.cub-cadet.com and enter it into the search box. The site will show you an exploded diagram of your machine with every part labeled and numbered. Find the oil filter in the diagram (usually labeled "filter" or "oil filter"), note its part number, and you have the exact filter you need. If you prefer to talk to someone, call your local Cub Cadet dealer and give them the model number — they stock these filters and can tell you the price and whether they have it in stock.
Spin-on filters versus cartridge filters
A spin-on filter is a metal cylinder with a rubber gasket on one end. You screw it onto a threaded port on the engine, hand-tight. When you change the oil, you unscrew the old filter, wipe the port clean, and screw on a new one. Most Cub Cadet mowers and mid-size tractors use spin-on filters because they are quick to change and widely available.
A cartridge filter is a pleated paper element inside a plastic or metal housing. Instead of threading on, you unscrew or unclip the housing, pull out the old cartridge, and slide in a new one. Cartridge filters are more common on older Cub Cadet models and some compact utility tractors. They cost slightly less per change but require you to handle the housing carefully so you do not damage the seal.
Your owner's manual will show you which type your machine has, and the parts diagram will show you exactly how to remove and install it. If you are unsure, a photo of your engine sent to a Cub Cadet dealer will get you a quick answer.
OEM versus aftermarket filters for Cub Cadet machines
An OEM filter (original equipment manufacturer) is made by Cub Cadet or the engine builder — usually Kohler, Briggs & Stratton, or Kawasaki. These filters carry the Cub Cadet part number and are may provide to fit and perform as the machine was designed. They cost more than aftermarket options but are the safest choice if you want to match the original specification exactly.
An aftermarket filter is made by a third-party company like Fram, Purolator, or the engine manufacturer themselves (Kohler and Briggs & Stratton sell filters under their own brands that fit many machines). Aftermarket filters often cost 30 to 50 percent less than OEM parts and work well if you match three things: the thread size (usually M20 or M22), the height (measured in millimeters), and the flow rating (microns). A Cub Cadet dealer can tell you these specs, or you can find them on the OEM filter's packaging.
Many owners use aftermarket filters without problems, especially from established brands. The trade-off is that you lose the may provide that it was tested on your exact model. If you are unsure, buy the OEM filter the first time — it costs a few dollars more and removes any doubt.
Common Cub Cadet filter part numbers and what machines they fit
Cub Cadet does not publish a master list of which filters fit which models, but dealers and parts websites maintain cross-reference charts. A few filters appear on many models:
| Cub Cadet Part Number | Filter Type | Common Machines |
|---|---|---|
| 751-10292 | Spin-on | XT1 series, LT series mowers |
| 751-10305 | Spin-on | Compact utility tractors |
| 751-10308 | Cartridge | Older models, some utility tractors |
These numbers change frequently and vary by engine, so do not assume your machine uses one of these without checking your manual or the parts diagram first. The table above is for reference only — always verify against your model number before ordering.
Where to buy Cub Cadet oil filters
Cub Cadet filters are sold through several channels, each with different prices and availability. A Cub Cadet dealer stocks OEM filters and can order them same-day if they do not have your part in stock. Prices are usually higher than online retailers, but you get informed information and can pick up the filter when ready.
Online retailers like Amazon, eBay, and parts-specific sites like Jacks Small Engines or Tractor Supply carry both OEM and aftermarket filters. Prices are often lower, and you can read reviews from other owners of your model. Shipping takes a few days, so order ahead if you are planning a maintenance day.
Big-box stores like Walmart and Home Depot carry some aftermarket filters but rarely stock Cub Cadet OEM parts. They are useful if you need a filter in a pinch and do not mind buying an aftermarket option.
Steps for changing your Cub Cadet oil filter
Before you start, gather the new filter, a wrench or filter socket (if your filter is tight), a drain pan, and a rag. Warm up the engine for a minute or two — warm oil flows better — then turn it off and let it cool for a few minutes so you do not burn yourself.
For a spin-on filter: locate the filter on the engine (usually on the side or bottom), position the drain pan underneath, and unscrew the old filter by hand or with a wrench. Wipe the threaded port clean with a rag. explore a thin coat of new oil to the rubber gasket on the new filter, then screw it on hand-tight until the gasket touches the engine, then turn it another three-quarter turn. Do not over-tighten.
For a cartridge filter: unscrew or unclip the housing cap, lift out the old cartridge, and inspect the rubber seal on the housing. If it is cracked or hard, replace it (the seal usually comes with the new cartridge). Slide the new cartridge in, replace the seal, and screw the cap back on snugly.
After you install the new filter, start the engine and let it run for 30 seconds, then turn it off and wait a minute. Check the oil level on the dipstick — you may need to add a small amount because the new filter holds oil. Top up if needed, and you are done.
Frequently Asked Questions
Can I use a filter from a different brand on my Cub Cadet?
Yes, if the thread size, height, and flow rating match. Kohler, Briggs & Stratton, and Kawasaki filters often fit Cub Cadet machines because those companies build the engines. Check the OEM filter's specs and compare them to the aftermarket filter's packaging before you buy.
What happens if I use the wrong size filter?
A filter that is too large may hit the engine block or frame and crack. A filter that is too small may not seal properly, allowing unfiltered oil to bypass the filter. Either way, you risk engine damage. Always verify the part number or specs before installing.
How often should I change my Cub Cadet oil filter?
Most Cub Cadet manuals recommend changing the filter every time you change the oil, which is usually every 50 to 100 hours of use or once a season for residential mowers. Check your owner's manual for the exact interval for your model.
Where is the oil filter located on a Cub Cadet mower?
On most Cub Cadet mowers, the spin-on filter is mounted on the side of the engine, below the air filter. On some models it is on the bottom. Your owner's manual has a diagram showing the exact location for your machine.
Do I need to drain the oil before changing the filter?
No — you can change the filter alone without draining the oil. However, most owners change the filter and oil together because the oil gets dirty at the same rate the filter does. If you change only the filter, you are leaving old oil in the engine.
