Features may include:

Powerful 37 hp (27.6 kW) engine has electronic fuel injection (EFI) and electronic throttle control for quick starts and superior performance

EFI with electronic throttle control

Electronically adjusts the supply of both fuel and air, responding instantaneously when the mower transitions from light to heavy mowing.

Unlike mechanical governors that droop under load, torque rises while maintaining constant full-throttle engine speed.

Productivity and cut quality are improved because the mower blades keep turning at full speed, delivering optimal cut quality and dispersion of clippings.

Immediate starting in hot or cold ambient temperatures or after long periods of seasonal storage

No choke linkage for the user to operate

Higher reliability with the elimination of vapor locking, misfiring, run-on, and after-bang

Automatic altitude compensation

Extra durability and mowing performance from 7-Iron™ PRO Side-Discharge decks pressed from a single piece of steel

Deck is forged from 7-gauge, 0.179-in. (4.6-mm) steel to minimize the number of welds and provide a smooth underside with fewer sharp corners for reduced material buildup.

Significantly fewer welds on the deck shell to wear or break - it is forged from a single sheet of steel rather than multiple fabrications. An anti-skid step on the deck provides easy machine mounting.

Extra reliability and long life with cast-iron blade spindle housings.

Higher blade tip speed than many competitors - approximately 18,500 fpm (5,639 m/min) for more blade cuts per inch mowed.

A deep-deck design of 5.5 in. (14 cm) delivers excellent airflow so material can be processed quickly and efficiently.

The wider and higher discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.

Quick-release belt covers do not require tools or the removal of a ring clip; just lift one corner of the cover and rotate it slightly to remove.

This makes it quick and easy for you to clean out trash that may collect around the spindle sheave.
