OK, I have to yeild to Keith's 16hp issues.......my 169 is fine when plowing (short runs, rough ground, pulled down further, etc.) BUT, man....when I mow with it it's rough/harsh!!!! 4 hours of mowing killed a hood hinge, completely tore it out.
Before everybody says 1650/ISO mount, I had this thing in a 1650 frame and it shook the heck out of it too.
How much can be gained by balancing the rotating assembly?????
I'm seriously considering puting this motor in the 128 and putting my fresh 14hp back in the 169 (actually 109) frame.
