I am working on the 50 hour service as recommended. I changed the engine oil and filter without incident. The manual recommends the transmission filter be changed. There are two filters, one on the left and one on the right side of the tractor (from the drivers seat). I believe the right side is the hydraulic filter and on the left is the transmission filter. I cannot remove the filter that the manual says is the transmission filter. it is way too tight. Perhaps I have mis-interpreted the manual. Any help will be greatly appreciated.

Same problem everyone else has with the factory filters. You may need a chain wrench to get it off the first time.

Yes the right side is the hydraulic fluid filter and the other is the HST filter, both should be changed at the 50 hour service.

Hello all, I'm trying to avoid starting a new thread, but haven't seen my question posted previously. I thought this might be a good place to start.

I hit 50 hours not too long ago, but was in the middle of a project and had to finish, so I'm a couple of hours past 50. I'm wondering if anyone knows of compatible filters for the L4701 Engine Oil, HST Trans & Hydro Filters rather than paying the dealer prices. Are there NAPA equivalents, or something similar? Or, should I just bite the bullet and get them from the dealer?

Thanks

Given that you have a brand new tractor with dpf filter and high tech engine whose warranty you'd like to keep in force, buying cheap filters for it could be an expensive mistake. Bite the bullet and make friends with the parts department at your dealer.

Thanks Sheepfarmer, that's the direction I was leaning to begin with, but I hate spending more money for something if I can get something just as good or better for less money. At least these filters aren't too terribly expensive.

Lots of folks in the same boat, want to save a little $$$. Kubota talked about an aftermarket "equivalent" fuel filter (referencing th L3301, 3901, 4701, and the MX's) a while back, going on to say that the "equivalent" filter only filters down to I think 15 microns, where the Kubota filter will go all the way to FIVE microns. They also went on to say that if an aftermarket filter was installed, and the engine suffers a fuel system failure directly related to dirt/junk entry into the fuel system, they can deny warranty help. Worth mentioning especially since the fuel system on these things is EXTREMELY sensitive to dirt/dust/poo entry-and if you ever have to pay to have one repaired, you'll beat yourself up pretty good. Not to mention the cost. A fuel rail is about $1500 by itself....pumps are considerably more, PLUS labor, gaskets, etc.

And on the other filters, I have personally witnessed an aftermarket filter's comparison to a Motorcraft when I did Ford's, and then again when I briefly did GM stuff, and the Motorcraft and AC demolished the "equivalent" filters away in EVERY way (flow restriction, particle pass-through size, filter media durability, construction, drainback valve, and canister construction). After seeing this, it's no wonder the other"equivalent" brands are cheaper; it's because they're cheaper.

"Equivalent" does not mean "same". To my knowledge, a Kubota filter has never failed due to a filter defect. John Deere on the other hand......we won't go there.

Looks like a Fram PH7328 for the oil filter...

But a Fram PH16 is longer, and a PH8a is even longer...

Look at the specs on Fram website...

AutoZone has STP s16 and S8a, for under $5...

A couple months ago a friend of mine had his Chevy Duramax diesel engine lock up at 25k miles. Dealer blamed it on the NAPA oil filter and denied warranty. Cost him $19,000.00 to replace the engine in his truck. He is seeking legal help to try recover some or all of his cost to replace the engine. I would spend the few extra dollars and use factory filters.

X3 on the chain wrench, but there are other techniques and tools that will work also.
I also recommend sticking with Kubota trans and hydraulic filters. You may find that the oem filters will only cross to Baldwin (which is a quality filter) and they aren't much cheaper.
I had a problem with Kubota filters on my L3410 years ago... The hydraulic filter blew out upon starting in 0 deg f weather. Turns out there was service bulletin out that required the filter's replacement in cold regions (one state north of me). Anyway, my point is that even oem filters are not exempt from failure, but the dealer came out and replaced the filter as well as the 3+ gallons of oil.
