I was at the dealer today shopping the Deere X380/390 against the 2021 Cub Cadet GX54D. I know that the K58 transmission on the X380 is not "easily" serviceable but in the X390 you get the drain cap, large cylindrical filter and a reservoir that you can use to fill from the top of the transmission. When I was looking at the transmission in the GX54D, which is listed as a K62AF, there is the same type of drain cap on the bottom of the case. There is also a fluid reservoir on the top of the transmission. When I conferred with one of the service advisors they could not find a large cylindrical filter that goes behind the drain cap drain cap on the GX54D like found in the X390 transaxle.
I am wondering whether or not this transmission (the K62AF) can actually accept the filter that is used in the K58 as found in the X390? Even if it does not, I would think that having the reservoir and the drain cap would have to make servicing this specific transmission easier. I have posted some pics of what I found underneath the GX54D.
I may have found the answer to my question. Upon looking at the schematics of each transmission it would appear as if the filter mates to a charge pump that is absent from the K62AF but found in the K58. Tuff Torq lists the K62 as having the option of a charge pump but I doubt that Cub Cadet would have opted for this feature when they are already opting for steel cut gears and differential lock.
