Well, the Gravely 148Z loaner has gone home, and has been replaced by.... a 2004 Exmark 52" Lazer Z HP with 23 Kohler and striping roller. What a machine! The HP is sweet. The cut and striping are incredible, even at top speed (in the few spots I can use it). The low center of gravity really helped hold it up when cutting the side of the berm on my yard. It dispersed clippings very well, and the deck setting adjustment works well. It's compact size left plenty of room in my shed. Gripes with my HP? I like the control handles on the Gravely better. I liked the cooling fan under the seat on the Gravely. The Exmark did not have the anti-scalp wheel on the front right of the deck, and even though the deck is really close to the front caster, it still seemed to want to scalp more than the Gravely. And petty as it seems, the keys were nicer on the 148 as well. I love my Exmark. Now, can anyone tell me if you can use an ultra-vac on a machine that has a masterchute ocdc?
