It is a full time job! Unfortunatley most wives don't appreciate how much we agonize over every attachment. /forums/images/graemlins/confused.gif
As far as Landpride RFM vs. New Holland MMM. The landpride had a slightly better cut. I believe it had a higher tip speed & the aerodynamics of the deck were better. The New Holland has to fit under the tractor, so the designers are constricted as to shape of the deck. That said, I wouldn't hesitate to use the MMM professionally. It is a commerical quality deck, in both it's manufacturing quality & cut quality.
As far as manuvering. The MMM wins hands down. The only advantage the RFM has is you can back under low tree branches. I either trim the brances up or mulch around the tree to avoid this problem. The RFM added 50% to the overall length of my TC18. When you turn left the mower swings right & vice versa. With the RFM in close quarters you are looking backwards all the time (stiff neck). I have lots of trees & other obstacles & the MMM makes mowing a pleasureable experience.
The RFM takes about 5 minutes to remove vs. the MMM 10-15 off, 15-20 on. It takes a little practice to get the techinique down. So if you envision heavy dirt work and are going to want the mower off often, that's a consideration. Also the RFM costs about $1,000 less than the MMM. ($2500 vs $1500). If you've got a wide open field, I'd say go with the RFM, if you've got lots of obstacles, go with the MMM.
