mmm vs rmm

Looks just like my YM240. It had what was labeled a YQM-60 MMM, but it would fit under just about any 2wd in the 18-40 hp range, as long as it had a Cat 1 TPH and a 1-3/8" PTO spline

Anyway, your follow-up post pretty much describes MOST rear PTO driven mid mound mowers. I'm bettin' your 272 JD MMM would fit my old Yanmar just fine. I'd even go so far as to consider yours as a "universal"

I sure mows nice, but its a real pain to take on and off.

Yup. Does that model require the lower lift arms to be removed, or was that done for some other reason? Mine hooked straight to the TPH as-is like any other implement. Removal was a breeze; drop the hydraulics, disconnect TPH/PTO shaft/chains, remove gauge wheels, then drive the tractor off - right over the top of the mower deck (that's why the gauge wheels had to be removed). Without a helper, it was about a 10 minute job to remove, 20 minutes to put back on.

Ground clearance will be an issue with an installed MMM

The top link and lower lift arms need to be removed. The gear box bolted on, cable pulleys bolt under the rear axle (where the lower lift arms bolted on).
Removal/install can each be a 1 hour job so I rarely take it off.

My first tractor had a MMM that had to be removed to use the front scraper blade. Big pain. Mainly due to that annoyance, my next tractor had a RFM. Because it worked well for me, the third tractor has a RFM. Some people prefer a rear discharge RFM, but I have always had side discharge mowers. They eliminate raking leaves in the Fall. Just mow from the center to the edges blowing the chopped-up leaves outward as you go....................chim

I have 1 tractor with a MMM and another that has a RMM.
If I was to buy again it would be a RMM.
The rear mower is easier to install/remove, cheaper to buy and with the mower behind you instead of under you I find it quieter to operate.
The MMM would be better if you have limited space and a lot of things to mow around.

I have both. I work with dirt a lot so I use the RFM most. The MMM get in the way big time with dirt or brush work. I bought the RFM because around here I have to cut the grass sometimes twice a week and hated putting the MMM on and taking it off.

If you use your tractor mainly for mowing get an MMM. If you have mainly trees in your yard get a MMM.

I actually prefer the MMM, but find it inconvenient.

I use my small 42" lawn tractor to cut around objects (two passes of 42"). Then I use the JD with RFM.

My rfm has to come on and off for each mow as inside storage is a premium and don't think I would like having a mmm attached when doing other work. Also I prefer the rfm for many of the same reasons as the others but probably the biggest preference is its mass and four wheels. I get a real nice cut for that very reason. Once you get used to pulling it it really isn't a problem with the swing associated with it hanging off the back. I actually do very little trimming and probably very little more than when I used a lawn tractor.
