I have a 60" mower deck on my B7100. If I bought a 48" mower deck, would it quickly interchange or is the actual bolt on mounting hardware completely different? I only want something i can quickly swap out.

If you're talking about a 3PH mower then I'd say ..yeah.

Why anyone with experience would would buy a MMM...I dunno.

There must be a lot of inexperienced people on these boards then.

Why go from 60 to 48 inches?

Only if you go from an RC60-71B to an RC48-71B series deck. I believe that anything in the -71B series will interchange.

oh yeah, i meant a B7100 48" mower and a B7100 60" mower. same 71B tractor and mowers for that tractor. that's good to know they should interchange, guess they attach the same way?

i'm looking for an extra deck to use as a field mower for mowing my fields and paths without hacking up my finishing mower blades for my yard. it'll only be used a couple times a year.

first i don't think i can find another 60" mower, but i have seen a 48" for sale.

there's a few paths that are up the side of a mountain, i mow backwards up the mountain. it's so steep i don't know what a 3PH mower would do for stability and if i could navigate those steep terrains and have the mower not get hung up...because it's not smooth either, lots of undulations and stuff. if you're going backwards and the grade changes substantially instantly, seems like the 3 point mower would hit or bottom out or something.

i am going to get a 3PH rear mower for my flat field, so maybe i'll wait until have that for a bit in case it would work. but i'm doubtful, that mountain is frightfully steep.

I would think the 3pt would be more stable and handle the dips and such better than a mid mount mower, if only due to the mower having more travel. A mmm only has a limited amount of travel before it bottoms out when going over a bump in the path. Coming out of a dip, you can always raise the 3pt clear of the ground if it is required.

ha ha, i'm getting mountain side mowing tips from flatland! that's awesome.

i had a suspicion about what you are saying being true, just not enough to pull the trigger on a 3PH mower. i probably will get one though, seems it'll be easy to pick up a used one.

though it's not really "bumps", more like a few steep grade changes, like shelves for a lack of better way of putting it. i guess i just raise the 3ph at those grades. with the MMM the rear wheels do it for you. i've never really used a 3ph mower except on flat land so i don't really know how they work on this stuff.

The 3pt rotary cutter will do a better job of trail mowing, especially if it get's away from you and is in the 12" or taller range. The B7100 will pull a lighter duty 4ft brush cutter reasonably well. For hillsides and steeper grades I would recommend some front weights for ballast as my 7100 tended to get pretty light in the front when mowing up hills with the rear mounted mower of 450lbs.

this is impossible to mow front first, there is no question whether or not it would flip. this is an extremely steep mountain side and i go backwards up it to mow.

thanks for the feedback. i will probably get a rear mower anyway for the flat fields so i can try it out and learn how it works/feels. if there's something awkward about it, then i'll get the MMM. so you fellows saved me from buying another MMM i don't need, at least for now, probably forever.
