Cat 320D LRR if your going to be bagging given your area is similar to mine i would go with the 34 efi. Reason being i have a exmark 52 with a 25hp and a 60 with a 27hp and i can tell the difference from one to the other. I wish they had the bigger 34 when i bought my mower. My dealer is only carrying the 34 on the X. Will only order the 27 or 29 if you don't want the vac or don't plan on having it. I can cut so much faster in the spring with the 52 because of the power it has over my 60.
