Well, I've done it both ways, front and rear blower.
IMO front while nice is only good with a hydrostatic tranny,
For speed a plow beats it all and when coupled with a rear blower for big events you have the best.
I found that a 7ft frt blower on a TN75 was a scary beast when working in close quarters as there was a wide swing in turns and visibility at blower corners was hard to judge due to angles and blind spots.
My setup is rear blower and backup camera installation combined with a front plow.
Plow for minor events and blower for major dumpings as well as reducing berms.
