I have a Gravely Compact pro 44 and I'm glad that I got the compact. I just started cutting a church and their cemetery and the 44 is perfect for getting inbetween headstones. I was also looking at the zt hd models, but the dealer pursuaded me to go to the commercial series and I'm glad I did. If I get really busy, I know that I have a mower that will stand up to the use. I got mine for $6000 out the door.
