48 inch Kubota Deck that know one can identify - RC48RTG

[Malwood]

on a lot of the older kubota decks the lower seal was a completely different type of seal. I don't remember the dimensions or numbers but a lot of the lower ones were a grease seal that would deal with higher pressures from greasing the deck. Some also sealed on a spacer or "boss" as Kubota called it which was large dia than the shaft itself.

pull the spindle apart. To get the seals out without damage, sometimes you can knock the bearings out from the inside and it'll push the seal out with it. That assumes there is no snap ring retaining the bearing under the seal.

Yes Auburn got bought out by Ariens a number of years ago. Had a family member who worked there for a little while before the buyout happened. Most of our family lived in Nebrask, most still do really but we are the black sheep rednecks out here in the hills of Arkansas. Yeah we wear shoes. Most of the time.

Hi Lugbolt,

Thanks for the info. I didn't expect to be able to get the seals out intact so I will try your method and see if I can manage to do so. Also a thank you for some very useful info you posted years ago about the HST on this tractor that was so useful I printed and filed it!!

These pics showing the seal numbers might help someone.

I am rebuilding a deck and have ran into an issue also, the preload spacer is preventing the bearings from being tightened and there is some vertical movement in the rotors. I have rebuilt without the centre spacers now, but I am concerned the rotors will loosen. I have also considered measuring the vertical movement and having the spacers machines to minimise movement. Does anyone have any experience rebuilding or adjusting this style of rotor with the spacer between the 2 tapered roller bearings?

Thanks RC for those pics. I haven't stripped mine yet as life got in the way last month so cant really comment on this as yet.

Regarding the blade solutions we discussed (as the blades on this deck seem to no longer be readily available and the hole size appears to be different to most other blades). This deck uses a 'top hat' style washer that locks the blade in place but I gave up trying to find any blades that had what seems to be a 24mm hole so here is my solution in case it is helpful to others...

Hopefully the photos are self explanatory but basically I turned the top hat washer upside down. Bought a new set of blades designed for a 48 inch kubota deck (standard blades not mulching in this instance) with a smaller 18mm hole but also sourced a nylon washer (ebay - see photo) which friction fitted perfectly to the blade bolt and sat perfectly in the blade hole to eliminate any side play. hope that makes sense with the pics.
