B100 - 36 inch mower compatibility?

[Brockport Bill 2,254]

Perhaps the Forum Administrators or other members can help clarify this issue?

the B100 Tractor is listed as manufactured in 74,75,76,77............there were 36 inch mower decks listed for those respective years as models 5-0721; 5-0621; 5-0722; 5-0622; 65-36ms01; 65-36xr01; 75-36ms01; and 75-36xr01. Also perhaps, 76-36xr01 ????

 

there were "next generation" or "successor" 36" rear discharge model decks including later in the 80's --- eg: 36 inch r.d. models 05-36mr01,and 02,03,04 etc

 

Can the 36 inch decks from the 80's be used on the B100 of the 1970s? Are they compatible? Thanks, Bill

This is a list put together from the Attachment Interchange. It lists the deck (2) that replaced the original (1) and the deck that was available when the Interchange was created (4). What is missing are the decks (3) between (2) and (4). They are listed but you have to follow a deck year by year to find the others.

The decks thru their final year in 2007 will work just fine on the 1977 and older B's. I'm still using a deck I purchased in the 70's on my 2005. I initially purchased it for a 76 B. Keep in mind that in 78 the B-series became lawn tractors so the interchangeability isn't there.

My 1974 B-80 came with a 36" RD deck, that is pretty much the same as the one that came with my 1987 310-8.
