I have a 72" Bushhog brand very heavy well made and I bought it used it is at least 15 years old now, in my experince, buy name brand American made, try to get one with solid tires and replaceable, also replaceable wheel bearing, and heavy gauge mowing deck, I have a side discharge but if done again, I would buy rear discharge, also there are a lot of moving parts, with a lot of viberation, so look over welds and buy one built out of heavy gauge metal will last longer.
