I added the 997 to the X749 and 5525 that I already had. People had told me about how much faster a zero turn would cut versus my X749...and they are right.
This mower is awesome. I have not had any of the overheating problems mentioned in other reviews. The ride is much better than my X749. I went with the 72" deck and it is awesome. What took me 4 hours to cut I can now do in about 1 1/2 hours.
I have ordered the same rear tires that came on my X749 for the 997 to give me better traction on a hill. Should improve that experience. I also ordered the front jack for easy access to the deck blades. This is a nice option that I will use often. The front headlights work well and the rear guard has already helped me keep the engine hood from getting damaged when backing into a tree. Overall I am very impressed.
