I have about 6 acres I would like to mow on a regular basis. I have decided on buying a ZTR mower, but which brand? My budget is between $6,000 to 7,000, so I have narrowed it down to 3 ZTR mowers. On paper they all seem similar, but would like practical advice on which to buy. They are the Exmark Lazer Z HP with 50" deck-23 kaw, the Scagg Tiger cub 48" with 19 kaw, and the John Deere 717a 48" 19KAw. The exmark is the high end at $7,000 and the John Deere is at the low end at $6,200. So, please help and give me some ideas.
