What size rotary cutter for M5660SUHD?

[GuidoSarducci]

Does blade tip speed increase with a larger diameter single spindle mower or will 2 gearboxes give a better cut?

The twin spindles start easier because of moving less mass and normally require less horsepower.. They also bring the weight closer to the tractor so less front ballast is needed on irregular terrain as they only stick behind the tractor the same as a 42" wide bush hog. They also are twin tail wheels so they allow higher ground speed and less beating of the machine on rougher terrain..
So a twin spindle will allow you to cut wider with less horsepower, less fuel burned. The twin spindle will cover the ground faster so that is less time and fuel. So you save fuel and time. Sounds like the cheap price might be costing you more the rest of the time you own it! Yes they are about 5,000 right now for the land pride or Bush hog 7' twin spindle but in the long run they are cheaper. Seen a lot of people buy what you are and then come back for the twin!

Thanks for the detailed explanation. That’s what I was looking for, why the twin is or isn’t better than the single. I’ll be going with an 8’ twin spindle.

highly recommend ballast of some kind up front, your chassis size is small for an implement of that size/weight. with ballast, you should be fine. assume your rear tires are loaded.
& yes, agree twin spindle is the way to go (if a tractor can handle it), i will never look back @ my 5' hog days,
best of luck, stay safe

Got the loader up front and that’s over 1,000lbs. My rear tires are filled but not the fronts.

sounds like a nice set up, & all the best w.your new tractor & brush hog. do check those 3 gearboxes, many manufacturers will ship with minimal gear oil. my Rhino takes 85/140, but yours could be different. & know you're anxious to start work.
i hit a yellow jackets nest yesterday hogging, only stung once. luck of the draw. take care

I saw a neighbor's 7' single box cut one day and I said I'd never have such. If you have any variations to your mowing area they are just too big. Better to get an 8' twin blade with dual rears. Ensure that you get the 90 hp gearbox, and not the 45 that winds up on 6' economy models most times. Standard boxes, not OEM specific self made, come int 45 and 90.

So when I went up from 6' it was with a Mohawk 8', as I described, used, originally used for highway mowing. Changed the fluid in the gearboxes, greased everything up, sharpened the blades and away I went for a great price.

Ensure you include front chains to protect your rear tires. Rear are required also in some instances like commercial mowing of roadways and such but problem with them is that they cause bunching of clippings so that your field looks lumpy rather than nice and smooth when you have finished mowing. I think if I had to have some for certain conditions I'd just put them on when needed. Not that big of a deal....3 or 4 bolts and they're off.

I would go with a 6 footer unless time is a big factor. They are much lighter and much more affordable. You can do 2 acres an hour on that setup in open fields.

I had an old 5’ BMB cutter running behind a 3038E. Caught some barbed wire and it went clean into the sidewall of my rear tire. Needless to say I now require chains on all my cutters.

GuidoSarducci, what is the measurement of the overall width of your rear tire spread? It would be nice to get a cutter that would at least cover your tire tracks. Also I heard of some complaints with the twin spindle models leaving some stalks standing at the blade overlap area.
