Scag SZL36-18FR 18HP Kawasaki 36" Liberty Z Rider

The Scag Liberty Z® is specifically designed for the home owner that wants a high-quality mower but does not need a large, commercial-grade unit. Now, there is no need to take a step down and buy a big box, throw away mower. Now, you can buy something that will last, and perform at a very high level.

The Liberty Z is designed, manufactured and assembled Scag tough, just like every other Scag product. It has a strong, fully fabricated (bent and welded, not stamped) cutter deck that is designed to last a long time, and deliver a beautiful cut. There are self-adjusting belts and sealed bearings throughout the mower to minimize maintenance.

Cover some serious grass with ground speeds up to 7mph and a large capacity fuel tank. The tube steel main frame and a heavy-duty steel bumper give the mower incredible strength and durability. An extra large footplate makes getting on and off the Liberty Z a snap, and changing cutting heights can be done right from the seat. Fast, easy, simple, reliable.

The high-back, contoured, padded seat fits like a glove and is very comfortable. The LIberty Z is so comfortable and fun to drive, you may just find yourself looking for more grass to cut!
