Features may include:
Stamped rotary decks and rigid frame construction to maximize deck durability
The 9009A TerrainCut Rough Mower is equipped with five and the 7400A TerrainCut Trim and Surrounds mower is equipped with three 68.6-cm (27-in.) stamped rotary decks for superior productivity and strength. The rotary decks perform exceptionally well across a wide range of grass types, including warm- and cool-season grasses.
A strong stamped, 10-gauge shell construction is an integral part of this durable deck. The stamped design uses a single piece of steel to form the shell that provides consistent strength throughout all areas of the deck. This is the starting point of the strength and durability of the deck construction.
Surrounding the deck is a tough, steel frame designed to protect the deck shell. It all starts with the frame on top of the deck which is then bolted to the shell providing extra protection. The front and rear roller brackets are attached to the framework, so as the front and rear rollers encounter obstacles, the force is transferred through the frame rather than through the deck shell. This design also decreases the distance from the blade tip to outside edge of the deck for closer trimming around objects like trees and fences.
An angled skid plate between the front roller and deck shell helps protect the front lip of the deck from tough terrain such as tree roots or other objects. The skid plate helps move the deck over the object to prevent the front edge from contacting and damaging the deck shell. The side of the deck also has additional protection to increase durability with a 38-mm (1.5-in.) tall and 12.7-mm (0.5-in.) thick steel stock welded to the decks edge.
Roller brackets are cast steel with extended housings to effectively protect the roller bearings from a wide range of debris types. The large front rollers are greaseable to help purge water and debris and use snap rings to ensure bearings stay in place, increasing durability and longevity of the front rollers.
Rear-discharge design provides premium cut quality and dispersal for less clumping and blowing for cleanup
The 9009A and 7400A TerrainCut™ Mowers 68.6-cm (27-in.) deck features a deck design with an asymmetric rear discharge cutout and molded chute to promote better airflow, leading to improved clipping dispersal and cut quality.
The unique shape of the deck shell cutout includes a heavily rounded opening on one side that gradually transitions to a larger opening on the other side of the cutout, allowing the grass to exit the deck evenly while significantly reducing the possibility of the deck congestion. This design incorporates deck structure along the bottom of the discharge area that reduces sound power, does not affect cut quality negatively, and acts as a foot guard eliminating the need for an external guard that can lead to external grass build up which can be dropped in the mowing pass over time.
When the asymmetric deck shell discharge shape is used in combination with the asymmetric discharge chute, this deck outperforms the competition in cut quality by minimizing clumping with smooth transitions and guiding the discharge material in a more dispersed pattern.
