I am moving to a new house in 2 weeks and have the need for a mower. The new place has about 3 acres to mow. It is fairly level except for one small hill, so I have decided to get a zero turn. I am looking at two models that Gravely makes. The HVZ 2350 for $3199 and the ZT 2348 for $4299. I also was considering the Cub Z-Force 50 for $3999 but I have read/heard some poor reviews on the cub's. I guess what I am looking for is anyone that ownes one of the Gravely's, and a good reason for me to spend the extra $1100 for the 2348. Is the IZT drive and the fabricated deck worth the extra coin??? Thanks!
