Mowing how do you install belt on MF 1231 mowing deck

[dlbeaty]

I need the schematics on how to install a new belt on a Massey Ferguson 1231 mowing deck series 5757 (60" deck)

This is for a different deck (2325, 60"), but procedure may be very similar. Maybe this will help.

Did you ever get the schematic for installing the belt?? I have the same issue (however with the 72" deck). I got a diagram from a dealer but it is totally wrong. I don't think it is for the series 5757 deck, although they say it's the right one. Thanks.

Here are some pics from my 1231 manual.

Thanks Dave. This is the same diagram that the dealer provided me. I Have since found out that this diagram is for the 54 and 60" decks but is not for the 72" deck (which I have). I understand that in some later issues of the manuals figure 78 is changed to include the 72" deck diagram. A dealer is supposed to be sending that to me. Just FYI the motor pulley and the spring loaded idler pulley on the 72" deck are on the left side and the fixed idler pulley is on the right. Thanks again for your help.
