I work with a volunteer group of guys called the Detroit Mower Gang. We work real hard trying to keep the grass mowed in the city parks for the kids. A brush cutter would be handy since the city is closing parks faster than we can cut them.
I have a B7500 which is 21hp tractor and I have a 4' bush hog. With you tractor being a 19hp I would recommend only a 4' as a 5' would be way to much load on the tractor. A good rule of thumb for implement width is 5hp per foot, 19hp divides down to about 4.
My 4' does not work my tractor and i have mowed stuff taller then the hood with no problem.
