MMM BX80 Question

[Ringman308]

I’m new to this forum. Want thank you for the info and advise. There has been a lot of good info provide.
My question stems from availability issues. There seems to be a lot more of the 60-in mower decks on the secondary market. And in my area, just about every dealer stocks new 60-in decks.

BX1880-1 says it is compatible with the Rck48-18BX, Rck54-23BX, RCK60B23BX
BX2380-1 says it’s compatible with the Rck54-23Bx, Rck60B23BX, but also Rck54D-26BX, RCK60D-26BX (drive over decks).

Can you fit a RCk54D or RCK60D to the BX1880-1?

The BX1880 can only use the smaller of the two MMM decks: 48” or 54”. Kubota USA website pdf (1 page attached) downloaded just now lists the options for non-drive over MMM decks.

hmm... IF you run a 60" deck you make 9 passes for every 10 using a 54" deck,that 'should' be a + BUT 60" deck is wider (6"+) so NOT good in tighter places....---

have to wonder how well a 18HP engine could spin 60" deck, especially the tall,wet grass most seem to have to cut.

I’ve seen that info. If you go into Kubota’s online parts catalo, the BX1880 lists the Rck48-18bx and Rck54-23BX as related equipment. The BX1880-1 lists Rck48 and Rck54 but also lists the RCK60B23Bx as related equipment.

if the Rck54-23BX is related equipment why wouldn’t the Rck54D-23BX work with the BX1880-1?
