The John Deere Max Z-Trak 797 zero turn lawn mower is another very large machine that is used almost exclusively by commercial contractors and professional landscapers. This is mainly due to the fact that it has such a large mower deck. This deck has a cutting width of 72 inches which means that it would be incredibly inefficient to buy for a small garden. The mower deck is constructed from super tough 7 gauge steel that has been stamped instead of being bolted or welded together. Inside the deck, there are 3 baldes, each of which has a diameter of 25 inches. The blades are each 0.25 inches thick. The mower deck on the JD 797 has an operating range of 3.5 inches from a low of 1.5 inches above the ground to a high 5 inches above the ground. It can be raised and lowered in very small 0.25 inch increments.

The engine powering the deck has an output of 29 hp. This engine has a displacement of 0.746 liters and is liquid cooled. The air intake into the engine is passed through a 2 stage air filter system. The first stage is a foam pre cleaner which gets rid of the larger particles. The second stage is the heavy duty canister air filter which stops small particulate matter from getting into the combustion chambers. The engine on the John Deere Max Z-Trak 797 is started by a 12 volt battery.

The John Deere Max Z-Trak 797 has a top speed of 17.7 mph (11 mph) going forwards, while in reverse, it has a top speed of 7.2 kph (4.5 mph). The speed and direction of the JD 797 is controlled using the lap bars in front of the operator. To make a zero radius turn, you just need to press each lap bar in opposite directions. If this machine is a little too powerful for you but you are looking for something similar, then take a look at either the John Deere Front Z-Trak F687 or the John Deere Max Z-Trak 777 lawnmowers.
