Design includes a heavy-duty formed and welded steel frame

ZTrak Mowers are designed around a heavy-duty formed and welded steel frame for strength and reliability.

Large front caster wheels and large rear drive wheels provide several operator benefits:

  • Smoother ride
  • Better slope performance
  • More operator comfort over uneven ground
  • Better traction


The operator platform is roomy and uncluttered for maximum comfort, and the controls are convenient to use:

  • Easy to get on and off the mower
  • Ample legroom for comfortable operation
  • Adjustable motion-control levers for height and position, enabling the operator to stay comfortable while using them
  • Color-coded and logically placed controls


Engine is smooth and powerful V-twin design

A V-twin engine with 44.2-cu in. (724-cc) displacement provides plenty of power and torque to handle tough mulching, mowing, and bagging conditions:

  • V-twin cylinder design for greater torque, lower vibration, and improved sound quality
  • Engine model M44
  • Electronic ignition for fast starts
  • Cast-iron sleeves for longer engine life
  • Overhead valves for excellent power and fuel economy
  • Spin-on oil filter with pressure lubrication for keeping the oil cleaner for long engine life and extended time between oil changes; pressure lubrication is also more effective when operating the tractor on an incline
  • Easy access to the no-tools oil drain valve for oil changes
  • Rear engine guard for protecting the engine and providing additional strength and integrity


The Z525E engine has extended life series (ELS) features for enhanced performance and longer life.

Replaceable fuel filter and oil filter are easy to access and change to minimize service time and cost.

John Deere recommends the use of fuel stabilizer in gasoline. See Fuel-Protect for gasoline engines (8 oz) for more information
