Re: 48\' MOWER OR 54\" MOWER bx1500
I presume you mean an MMM, not an RFM?
My
BX2200 has far more than enough power to run my 60" MMM. I'd guess the
BX1500 has plenty of power to run the 54" MMM.
I'd think the 54" should cut more grass faster. It will have a 3" narrower turn radius when cutting around things like trees, so less forwards & backwards movements doing so.
Do you have to cut between any two objects that are more than 48" apart yet less than 54" apart? If so the 48" fits & the 54" doesn't. On the other hand, it you have other objects with something less than 48" between them, you're still going to need a little push mower or string trimmer to get between them anyway.
Getting a 60" MMM attached & detatched from a
BX2200 can be an involved task (if you care to, you might want to search the archived threads). I have no idea re. this but I wonder how the 48" & the 54" compare in ease of attachment/disattachment. A smooth paved surface makes a huge difference. If you don't have one, getting the MMM out is harder; will the few pounds less weight of the 48" matter in that case? (Some people just drive over the MMM, but I wouldn't.) If you're using your
BX1500 exclusively for mowing, this is a moot point. If you only need to remove the MMM on rare occasions, it might not matter too much. If you need to remove it often (the lift arms for the MMM & the lift arms for the rear 3ph move simultaneously-if you lower a rototiller on the 3ph & you have the MMM still attached, the mid-arms will lower the MMM at the same time) then this is probably something to consider.
Good luck with your decision.
