Caroni flail mower
The type B rotor (56 blades) seems to be what is advertised most for the Caroni TM1900. Is there any disadvantage to the type F rotor with twice the number of blades?
Going to buy one soon and need to decide.

Ah yes, the "either or issue".
The F rotor will cost more but the greater number of knives for slicing grass and brush are worth every penny; especially mowing wet brush and turf.
The 4 row F rotor will provide you with a better cut and you can go from brush to turf and back to brush with out changing knives
and you wil have nothing left to clean up other than possibly going over thick weed stalks twice.
I have a mathews 48 inch lawn genie with staggered knife hangers and The grass slicer Y blades and I have been very happy with it as it takes much less time to mow turf than with our wheel horse 525 with the 60 inch deck.
The F rotor will have more knives mowing the entire width of cut at all times slicing the grass or brush into very tiny bits with little left to see on the ground and it will slice up any left overclippings and slice them even more.
All depends on your turf or brush situation and how much time you spend motoring around the place to mow.
The nice thing about the grass knives is that when they slice the grass blades they stress the grass much less than a rotary mower and the same thing occurrs witht he cup knives for grass slicing- you need to proceed at a slower forward speed to get a nice turf edge though and the cup knives tend to ding up more where the Y blades have huge cutting surface in total inches of slicing edge.
Either way you wont make a mistake but the F rotor will be a plus with any thickness of brush or overgrown grass which eliminates buying hammer knives for a B rotor.
Having the four rows of knives will make mowing a breeze with few if any clippings to see and if there are any you can just goe over it again and slice them some more.
The one drawback with the B rotor is you have to drive slower to get a finer sliced turf and brush work
please be sure to purchase the spring disc type slip clutch PTO shaft for your tractor and mower as it is the first line of defense for your tractors drive train after the mowers V belts.
Edit: You have to run the engine at the proper high rpm to maintain the 540 RPM speed delivered to the rotor or you will plug up the mower and burn the belts as it is not cutting at a high rpm of 100 MPH or greater under the mowers hood.
