152-cm (60-in.) 7-Iron PRO deck shown

7-Iron PRO mower decks have demonstrated quality, performance, and durability. They deliver a high-quality cut in diverse conditions.

Key features of the 7-Iron PRO mower deck:

Deck is stamped from 7-gauge, 4.6-mm (0.179-in.) 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 stamped from a single sheet of steel rather than multiple fabrications. An anti-skid step on the deck provides easy machine mounting.
A deep-deck design of 14 cm (5.5 in.) 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.

Mower rectangular leading-edge reinforcement

Dual-captured anti-scalp wheel

Deck has rectangular leading deck edge reinforcement and the rounded corners of the stamped deck help distribute impact stress to reduce the potential of damage when the mower contacts trees, rocks, curbs, and other fixed obstacles.
Dual-captured front and rear anti-scalp wheels provide deck flotation over even the toughest terrain.
Three 2.5-cm (1-in.), cold-forged spindles are heat-treated for strength without bulk and are supported by ball bearings, providing reliability and performance; spindle housings are ribbed cast aluminum providing both excellent strength and heat dissipation.
The front edge is raised above the blade plane to allow even cutting of tall grass and is reinforced with a square bar for durability. The front baffle has been redesigned to better manage airflow and control clippings.
Three spindle grease fittings are accessible from the top.
Blade overlap is 40.6 mm (1.6 in.) to reduce striping between blades.
Quick-change, cutting-height adjustment.
Optional mulch kit for 137-cm (54-in.) deck

Commercial-quality deck design

A large volume of material can be thoroughly processed with the deep-deck design:

Unique baffling system is designed to reduce clumping and windrowing often associated with rear-discharge mowers.
- Efficiency is enhanced with baffles surrounding each blade to control material as it is moved to the rear.
- Material exits the deck quickly as the baffles are lower at the rear.
- Movement of material is controlled to minimize the likelihood that clippings are thrown onto unwanted areas.
Less debris gets on the operator as material is directed to the rear and toward the ground.
- Debris is kept low and directed into the turf by the flexible rear shield.

Level cut

Center deck rollers and right wheel

Right-rear deck wheel

The deck is suspended from and supported by the machine to provide a level cut. Mower deck wheels and rollers help smooth out the mowing job in uneven conditions and reduce the chance of scalping the lawn:

Two wide front rollers at the center of the mower support the deck when necessary to prevent scalping.
Wheels at all four corners protect the deck from scalping at the sides of the mower.
Continued effectiveness results from wheels and rollers that are double captured for extra strength, which reduces the chance of damage.
Height of rollers and wheels is adjustable to suit mowing conditions.
- Higher setting (shown in images) are used when mowing at lower cut heights and for rougher conditions at all cut heights where you want to reduce the chance of the wheels hitting the ground.
- Lower settings are used for higher cut heights and for helping to smooth out the mowing job.
Mower cut height is adjustable from 2.54 to 14 cm (1 to 5.5 in.) in 0.64-cm (0.25-in.) increments from the machine operator’s station.

Heavy-duty components for long life

Strong, reinforced deck

Easy-to-operate height-of-cut adjustment enables on-the-go changes

Mower deck height adjustment knob

An easy-to-use cutting-height lift system allows the operator to adjust the mower deck height with no tools and minimal effort. The easy-to-grip knob allows operators to dial in the desired height of cut (HOC).

Cutting height can be adjusted from approximately 2.5 cm to 14 cm (1 in. to 5.5 in.). Each increment on the knob adjusts the HOC approximately 6 mm (0.25 in.). The deck can also be raised and locked in a transport position to provide maximum ground clearance when moving the machine from one area to another.

The transport lock function allows the deck to be returned to the previous HOC after being in the transport position:

Use the foot-lift pedal to lift the deck and engage the transport lock.
Rotate the knob to adjust from 2.5 cm to 14 cm (1 in. to 5.5 in.) in 6-mm (0.25-in.) increments.

This design increases productivity by allowing operators to change the cutting height without having to leave the seat.

Standard comfort and convenience allows for easy deck height adjustment and power take-off (PTO) shutoff
