John Deere Z345M 42 Zero Turn Riding Lawn Mower Review

The John Deere Z345M is an ideal zero-turn riding lawn mower for the people having land of 2 to 5 acres and wanting a smooth and great cutting experience with the ability to maneuver swiftly around the pathways and objects.

Due to its heavy-duty frame tubing giving it a strong body and its big sized rear wheels the mower can take some jerks over some bumps and a small slope without affecting the running of the mower or the riding engine. The seat is suspended with two springs giving the comfort to the driver/operator over a hill or an uneven ground area.

Features of John Deere Z345M: 

This riding mower offers great power from its 22hp ready start engine branded by John Deere (manufactures highly reliable and efficient engines for tractors and other vehicles). The mower can go to a mowing speed up to 7 miles per hour while going forward and up to 3.5 miles an hour in reverse. The speed and direction can be controlled by twin levers on the side.

The ready start engine mode in this mower offers the comfort of not having to pull a lever to start the mower but can be started just like a car does. The engine has an amazing capacity of 3-gallon fuel at a time. The mower features a deck of 42 inches which covers three large blades whose height being able to adjust gives you a range of cutting heights increasing your flexibility and effectiveness.

The blades can be set at 1 to 4 inches from the ground with an adjustable hand lever and a foot lever which can increase or decrease the height with 0.25 inches per increment/decrement. The platform above the deck can also be removed for easing the purpose of cleaning and maintaining the deck. This product also features a 2years or 120hours bumper to bumper warranty from the company.
