I use dixie chopper on 12 acres its 60 inch cut 28 hp EFI engine this my 5th year cutting. Blades belts oil filters and one battery in five years that all I've had to buy so for I can see in near future set tires coming up dry rot. If buying new mower to cut larger I would go for 74 inch cut and 40 hp motor it cut 12 grass weed very easy. There a lot zero turn mowers that cut your 6 acres but I say try out dixie chopper first you want need dealer very much for repairs last I hear you return one if got less 60 hours on mower without problem.

I think thats what ill wind up doin this dealership has demos I can take home for a week at a time. Everyone around my neighborhood is saying kubota. Even tho it is heavier than the other 2 it is a diesel. Im not worried about it sinking in yards not very many of the properties I manage has soft ground. Plus the Kubota I will get a free dump from the seat bagger and a light kit installed on the rops for about 17Gs financed with no APR%. But the only draw back is that the kubota is twice the price than the other 2. But hey what do you expect its a beast. The dealership says they sell more than 20 times more Kubotas than they do any other tractor for wat I need it for.

Having owned an L100, I know it is not the 120 but close, I would say it can handle what you state you have, just maybe a few more turns. As far as the X304, which is what I have now and lovin it compared to your exMark zero turn, all I can say is look at the quality of both machines. The AWS has been around and proven, the Zero turn is relatively new and has no real reports as to it's reliability down the road. Being that both are the same price I'd go green but the decision is something that you have to live with..

Don't know your situation but I just bought a 20HP Ariens from Home Depot, using the $250 "bath" cupon code, had to add a cart to the deal to get the coupon, but with free shipping to my door (cross country in 7-8 days) an almost free cart and the fact that the Sears and Ariens are all made by Husqvarna in the same factory, it seems like a good deal. A zero turn will get almost into corners but for the price of the yard tractor??? Down side is that Home Depot has very little customer support for this, upside the Agri-fab brand front tractor scoop from sears (and Husqvarna) bolted right up and from calling a Husqvarna dealer who measured the rims on the rear it seems Husqvarna wheel weights are a direct bolt on option. With free shipping, at under $1400 bucks, I just don't know. I used to be a Craftsman fan BUT the quality and customer service today stinks, mostly the customer service which we used to depend on, all thing being equal I would not buy from Sears again, I only bought the scoop as it was on sale and over $100 less than the local Husqvarna dealer wanted for it. $1000 more for zero turn (trust me you will still need to trim with a mower or string trimmer) or a std lawn tractor is all up to you.
