The 20-HP, V-Twin John Deere engine has plenty of power and torque for the Z315E to handle tough mulching, mowing, and bagging conditions – most suitable for a flat with obstacles terrain, up to one acre.

Smooth, powerful V-Twin engine

  • A 20-hp (14.9-kW) V-twin M40 engine provides plenty of power and torque to handle tough mulching, mowing, and bagging conditions. The engine is V-twin cylinder design for greater torque, lower vibration, and improved sound quality, with overhead valves for power and fuel economy.
  • A full-pressure lubrication and oil filter keeps oil cleaner for a long engine life and extends the time between oil changes; and there’s easy access to the no-tools oil drain valve for oil changes.
  • A rear engine guard for protects the engine and provides additional strength and integrity.

Get an even cut with the 42-in. (107-cm) Accel Deep™ (42A) Mower Deck

  • The 42-in. (107-cm) Accel Deep Mower Deck is a stamped-steel, deep, flat-top design that delivers excellent cut quality, productivity, cleanliness, durability, and versatility. Optimal performance and dispersion of clippings is provided, even at faster mowing speeds.
  • 12.6 cm (4.97 in.) deep throughout the entire deck shell for optimum mowing, mulching, and bagging performance.
  • Stamped-steel design eliminates sharp edges and corners where material can build up and diminish mowing performance
  • Mower deck suspended from the vehicle for a smooth and level cut
  • 6.4 mm (0.25 in.) cut-height increments allow the mower to be set at the desired cut height
  • Compatible with efficient 230 L (6.5 bu) two-bag cut-and-throw material collection system

Comfortable ride delivered by operator station with adjustable controls and seat position

The operator station is designed for operator comfort and convenience when operating all controls:

  • Excellent visibility forward and to the trim side of the deck makes operation easy and comfortable for the operator.
  • Controls are color coded for easy identification.
  • Translucent fuel tank displays fuel level.
  • Twin-lever controls adjust, using cut-height pin/socket, for convenience and operator comfort.
  • A shock absorber dampens motion control lever movement to give smooth operation.

Great appearance, reliability, and performance delivered by a heavy-duty design

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

Efficiency and durability from dual transmissions with large, 2.5 cm (1 in.) diameter axles

Dual transmissions efficiently power the ZTrak™ mower forward and reverse and give steering capability:

  • Transmissions are set low in the vehicle for excellent hillside stability.
  • Hydro-Gear® transmissions are reliable and durable.
  • Maintenance-free unitized transmissions are sealed and have no hose connections to leak hydraulic fluid.

Easy refueling with a conveniently located fuel tank

The fuel tank holds 11 L (3 U.S. gal) of fuel. It is located low on the left side of the machine:

  • Fuel-fill opening is located low and angled for easy refueling.
  • Large, 5.1 cm (2 in.) fuel-fill opening reduces the chance of spilling when adding fuel.
  • Cap is tethered to the fuel tank to prevent the fuel cap from getting misplaced.

Translucent fuel tank displays fuel level.
