I have an acre of land and I'm looking at the 1042 vs. 1045. The motors are very similar (one hp difference). The decks however, 42" vs. 46", one having 2 blades and the other having 3. My question is I know the 46" cut will get me finished faster, making the extra $100 price worth it, but are there any considerations in going from 2 blades to 3? My experience is more moving parts = more trouble later. I'm looking to make a purchase in the next week so any help would be greatly appreciated. I've done alot of research on mowers and it seems like CC makes a great product. Thanks in advance.
