The John Deere Z520A lawnmower is the bigger brother of the John Deere Z510A mower and is a member of the John Deere ZTrak Estate Z500 series of lawn mowers. It is a non current model of zero turn radius mower from John Deere that many people are quite fond of. As it’s a big machine, it has a correspondingly big engine. It’s a Kohler 2 cylinder, gasoline engine. It’s engine size is 0.725 liters (44 cubic inches) but produces 25 horsepower to drive the machine forwards as well as powering the mower deck. The JD Z520A’s engine is air cooled and uses full pressure lubrication to help prevent wear and tear.

The John Deere Z520A is designed for heavy use and large grass cutting jobs. As a result, it has a massive 26.5 liter (7 US gallon) fuel tank. The top speed of the JD Z520A is very impressive, clocking in at 16 kph (10 mph), while it’s understandably slower when reversing hitting up 8 kph (5 mph). Thanks to it’s ergonomic handles, this John Deere mower is really easy to operate, even for extended periods.

The John Deere Z520A could originally be bought with 2 different sized mower decks. The smaller mower deck has a cutting width of 54 inches, while the larger mower deck has a cutting width of 60 inches. The size of the mower decks, combined with it’s high speed, makes the JD Z520A a favorite among professional landscapers and commercial contractors when cutting the lawns of very large parks, gardens, golf courses and playing fields. Grass is discharged out the side of the Z520A. This lawnmower is a big one. It’s weighs in at 510 kg (1125 lbs). The John Deere Z520A comes with a 2 year or 300 hour warranty (whichever comes first) for those who purchased it. The people buying this lawn mower are almost exclusively private contractors and not individuals, due to the size, power and cost of it.
