Brief addition to the list.
eXmark has added a 31hp gas model Lazer XS for 2005.
This is the machine I purchased in May and love it!
The biggest thing to look at on this chart is the tire sizes. I previously used a Woods Mow'n'Machine that couldn't hold a line on a slight grade due to the small tires.
This eXmark is a monster and has 26" drive tires. It will climb and stop anywhere I put it. Only thing you have to watch is momentum downhill on wet grass as you are trying to stop almost 2000 lbs.
New XS with 60" deck, the QDS hopper style grass catcher (no bags! - just back in, pull the handle on either side you want and you're off!), Full suspension seat (std.), tow plate, and sun shade for $12,000 delivered.
Service has been great. Lost a bolt - no charge. 10 hour break-in oil change was a snap.
This is a great machine! Very stable. Enjoyable to drive with HD pumps which require little effort to turn.
Cut my father-in-laws 10 acres in about 8 hours (His JD with 7' Wood's FM died). Even has a cup hold for a fine cold one on a hot day!
I highly recommend this machine for anyone who needs to cut a large area and doesn't want it to be a chore. It also cuts nicer than anything I've seen.
