Lonny;
I have corresponded with the CC folks several times before purchasing the GT1554 and they offer a sleeve hitch for it and recommend it for plowing as well as several other chores including blading and tilling. They also offer a hydraulic tiller, Item No. 190-825 for the GT1554. It has a heavier rearend than the smaller 1000 series and is backed by the CCC company for the task mentioned above.
I purchased a Craftsman 10 hp lawnmower back about 20 years ago. It was small and had a 38" deck on it, designed only for mowing. Over the coarse of time I began using it for chores around the farm. It had a peerless transaxle not designed for gardening but I put bar tires and wheel weights on it and used it for hauling firewood and fencing pulling a 4 X 6 trailer that was loaded to the top a lot of times. Granted, I did have to get a running shot at some larger hills sometimes but it worked and it had the "rubber band" drive as all of them do. It came with a Tecumseh engine which I wasn't crazy about but it lasted for about 10 years under my abuse and I replaced it with a BS 12hp engine and kept on trucking. I also pulled a 6' heavy duty culitpacker with it when sowing my yard and parts of my 8 acre pasture.
About two years before I sold it, I purchased a Swishwer 60" pull behind mower as the deck on the Craftsman had finally bit the dust. I mowed my yard, about 3½ hilly TN acres with it without a hitch. I finally got tired of having to keep two riding mowers and the pull behind mower maintained so I sold them all in a sale and bought the GT1554 with a 54" deck.
I said all of this to say that the GT1554 is 10 times the machine the little Craftsman was so if it could do what I did with it under extreme abuse, the GT1554 should do what the Cub Cadet folks have told me it will do.
I did a lot of research for about a year into the different brands of garden tractors from the John Deeres to Craftsman and for my available cash, I feel the GT1554 will handle anything I have to do with it. No, it isn't the machine the 3200 series is, but then it didn't cost what one of those would, either. Yes, I would rather have hydraulics and cast iron heavy duty axles but then if I were going to put that much money into a small garden tractor, I would go another step and purchase the 5200 series and then you would have a true tractor with cat. 1 3 pt. hitch and everything but still in a small enough size to handle your yard mowing chores as well as gardening and most anything else you needed to do plus you would have the option of more accessories such as a front end loader.
