Thanks to all who assisted. I appreciate it. And I'm sorry for misstating the model as XT725. I conflated the Cub Cadet model XT1 with the Kohler KT725. It's not as difficult to do as you may think.

That's the OE filter for the KT725.
It's also a good choice.
I was hoping that he would watch the video and get a better understanding of the various filter applications.

The video, posted by MParr, is not very helpful.
Pleated filter media can do a good job , however it is hard to judge the degree of material caught/blockage and there is the ever present risk of the media breaking down and entering the carburettor. Use a gauze filter medium.
Opaque filter casing do not allow inspection at all. Need to be replaced at regular intervals ($) as the operator has no idea when they may be about to block. Use a clear/transparent filter.
The in- tank "filter" is known as a "Finger Strainer" - its main job is to catch large contaminates, before they enter the supply system. More appropriate filtration can/usually takes place down stream before the carburettor.

"Need to be replaced at regular intervals" That is correct. It's best to change them yearly or ever 100 hours. They are relatively cheap. Also, the super cheap stuff sold on Amazon or Ebay are not the best. OEM, Stens, or Rotary are fine for that time period.

My point is: Replacing an opaque filter at regular intervals, does not allow the maintainer to exercise judgement ie does it really need to be changed.
If the maintainer/operator exercises good refuelling "hygiene" the inline filter may not need replacing for many years. Saving $ You will only have confidence in doing this IF you can see the filter media (gauze)
I recently changed the filter on my ZTR. It had been on my mower for around a year. Inside was a very fine light colored sludge. The filter was a 10 micron Kohler filter. Any filter with a higher micron rating would not have captured that junk.
