Looking for a new mower and liked the Exmark Quest 50", in checking into competing models I looked at the Toro 5060 and it appears to be and identical machine. Since Toro bought Exmark it does not suprise me that they have put this in at the lower end, but does anyone know about the performance of this mower. I will be using it to mow about 5 ac and am worried it is not "commercial enough" to stand up.
