i have a zetor 5245 4x4 , and i hooked up a logging winch to it, i noticed with the three point hitch all the up my winch is only coming off the ground about 12 to 13 inches,, i thinking that its not going all the way up ,,, does anyone know why my three point hitch is not coming up the whole way,,Without the winch attached and the three point hitch up as far as it will go , i can manually lift them anouther 10 inches.. is this normal.
