Five decks, two groups
The Liberty Z splits into two groups. The 36 and 42-inch models run a Hydro-Gear ZT-2800 transaxle and a 3.5-gallon tank. They get a padded seat with no armrests. Engines are a Kawasaki FR or a Kohler 7000, at 18 to 22 hp.
From 48 inches up, you get a Tuff Torq TZ450 transaxle, 5.5 gallons of fuel and armrests. A Scag SR engine joins the list, and the 52 adds a Briggs & Stratton PXi. Horsepower runs 21 to 24 on the 48, 23 to 24 on the 52 and 24 to 27 on the 61.
Weight runs from 555 lb on the 36 to 695 lb on the 61. Top speed is 7 mph forward and 5 in reverse, whichever deck you choose. The bigger three also ride on wider 11 x 6-5 front tires.
Sizing it to your place
Start with your gate. The 36-inch measures 48.5 inches with the deck out, and the 42 measures 54.5. They'll go through openings the bigger decks can't. The 48 and 52 come in at 60.5 and 64.5 inches. The 61 is 73.5 inches wide.
Then think about the open ground. A wider deck cuts more on each pass. So if you've got a few acres or more, the 52 or 61 gets it done in fewer passes. If your yard is mostly trees, beds and fence lines, a smaller deck is easier to steer around them.
Whatever size you pick, the deck is built from 2 steel plates. Cutting height runs 1.5 to 4.5 inches. Want more speed and a bigger tank? Look at the Freedom Z.

Questions people ask
What's the narrowest SCAG Liberty Z?
The 36-inch model, at 48.5 inches wide with the deck out. It weighs 555 lb and runs a Kawasaki FR or Kohler 7000 at 18 to 20 hp. If you've got a fenced backyard or a narrow gate, it's the one to measure first.
Which SCAG Liberty Z models have armrests?
The 48, 52 and 61-inch models have a padded seat with armrests. The 36 and 42 have a padded seat without them. The bigger three also carry 5.5 gallons of fuel to the smaller pair's 3.5, so you'll stop to fill up less often.
What transmission does the SCAG Liberty Z use?
It depends on the deck. The 36 and 42-inch models use a Hydro-Gear ZT-2800 transaxle. The 48, 52 and 61 use a Tuff Torq TZ450. Both setups top out at 7 mph forward and 5 mph in reverse, so you won't feel a difference in pace.

We keep current pricing on our live inventory page at j5tractors.com, where our Navasota stores list the SCAG mowers they have.
