B2410 MMM support

[Rodney]

I know this question may be out of season especially since we have 22" of snow on the ground, but how do you hold the mmm up when using the 3pt hitch? There is a place to slide two pins in to support the front of the mower. I don't see a way to support the back of the mower. When pinned in front the back sags when I try to use the 3pt with other attachments. I have been removing the mmm when using another attachment, but I know there has to be an easy way to support the rear of the MMM. Maybe someone has a pic or can point me to a post that describes this. I expect it is the same as the B7500 and B2710 also but do not know for sure.

Thanks
Rodney
