Rear weights (UC13263) are required based on machine configuration. Must also order TCB10303, rear weight mounting bracket.

*Mower deck offset for trimming capability. Vehicle track width is 2 in. (5.1 cm) wider on the discharge side of deck. This may cause the tire to drive over uncut grass on discharge side of deck.

NOTE: These mower decks will not retrofit to F900 Series or F1145 Front Mowers.

Rotate for Service (RFS™)

Rotate for Service (RFS) feature provides access for cleaning and maintenance of the mower decks:

The rotation angle will vary depending on deck size and power unit tire size.
No tools are required to access belts.
The underside of the mower deck is easy to access.
Easy on/off design simplifies installing and removing mower decks.
Top, greaseable spindles can be accessed without removing belt covers.

The Rotate for Service position also reduces the length of the machine for trailering.

Certification

TerrainCut Front Mowers comply with ANSI B71.4 safety certification.

Heavy-duty blade spindles

The mower spindle housings are made of ductile cast iron.

Key benefits of ductile cast-iron spindle housings:

Ductile cast-iron material provides superior impact strength.
Gusseted design puts reinforcement where it is needed.
Strength of cast iron protects against damage from blade impacts.
Grease fitting is mounted at the top for easy access.
Grease pressure-relief valve minimizes seal damage from overfilling with grease and keeps debris from entering housing.
The 8-in. (20.3-cm) diameter housing distributes loads and impacts to minimize deck-shell damage.
Spindle allows ability to be rebuilt.

NOTE: The 72-in. (183-cm) 7-Iron V-Flex Side-Discharge Mower Deck has an aluminum center spindle housing. The outside blades are driven by cast-iron gearboxes.

60-in. (152-cm) 7-Iron PRO Side-Discharge Mower Deck

Features include:

Blade tip speed of 18,000 fpm (5486 m/min) for more blade strikes per inch mowed.
Trim-edge bumper reduces damage to the mower deck and property.
Redesigned front baffle manages airflow and controls clippings better.
Blade spindle housings are made of ductile cast iron
- Gusseted design puts reinforcement where it is needed.
Spindle pocket reinforcement gives even greater structural durability.
Adjustable anti-scalp wheels help smooth out the mowing job.
Standard semi-pneumatic caster tires will not go flat from punctures.

The mower is designed to provide exceptional cut quality at higher travel speeds:

The mower deck is stamped 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.
- Provides precision components and long deck life
- Single piece of steel means no welds to break
- Provides a smooth underside, without corners, reducing material buildup
0.75-in. (1.9-cm) solid steel bar is welded to mower deck perimeter for added strength.
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.
A deep-deck design of 5.5-in. (14-cm) delivers excellent airflow so material can be processed quickly and efficiently.
1-in. to 6-in. (2.5-cm to 12.7-cm) cutting heights, in 0.5-in. (1.3-cm) increments, allow the operator to match all mowing conditions.

Unique baffling system allows grass to stand up before being cut, producing a uniform length and appearance:

Baffling system eliminates clumping, blowout, and windrowing.
Wide discharge opening provides even clipping dispersal for an excellent, finished appearance in all conditions.
