I have twenty acres of relatively wet and hilly overgrown Vermont pasture. I have a 1428 MF compact tractor with FEL. (28 HP) I have been shopping for a rotary cutter and have been steered away from the "disposable units like King Kutter and Rollins" toward a 4ft MF ($1150.00) or 4 ft Woods unit (1250.00). I am told a 5ft is too much so I need the 4ft. The Woods unit has a clutch which is "a necessity" and the MF unit does not because the clutches "always freeze up" and the "shear pins are safer" (I can add a clutch to the MF for $163.00.) I did have one guy tell me I could use a 5ft Rollins or a 4ft Woods but not a 5ft Woods because of "the difference in gearboxes and weight of the units". "The MF units are built better that the Woods" and vice versa. Another said that "the Rollins is just as good as the Woods or MF units ....you are just paying extra for the paint" UGH! I have read many of the previous posts regarding rotary cutter but at this point I am just confused and would welcome any and all advice. I am not using the cutter commercially. I will mow my fields for to five times a year. There are rocks and stumps and there is some serious mud if any of that matters. Thank you in advance for your help.
