G'day Tyler,
Morrison has been Masport's 'second tier' mower brand for quite a while now, but you've certainly scored one from the top of that range there.
Alloy chassis with washport is the giveaway for that. Does it have the 2 or 4 blade setup?
Though only an electric mower is now offered in Oz under that brand, they still offer a good range of petrol mowers in UnZud.
