The 107 cm (42 inches) Edge ™ mower deck adjusts to the conditions

The innovative design of the 107 cm (42 M) chopper cutting deck sets a high standard for grinding grass and leaves:

Removable inserts for ejection of cut grass overflow
Adjustable for optimal performance in a wide range of conditions
Flexible operation in all conditions
Uses a standard V-belt and unsynchronized blades for greater reliability

A storage location on the cutting deck is provided to store the inserts.

The lower part of the cutting deck is contoured and free of obstructions:

Ensures a smooth flow of cut grass
Minimizes grass accumulation
Designed for grinding and ejecting cut grass
Reduces fertilizer requirements
Eliminate the chore of scrapping
Remote mower blades allow blade overlap with the use of a standard trapezoidal drive belt
Guarantees that the blades can not come into contact with each other
Allows ejection of cut grass overgrowth under grassy conditions with two removable inserts on the back of the cutting deck
No ejector chute
Allows a bilateral mowing
Reduced storage requirements
No tools needed to remove inserts
Equipped with two gauge wheels for uniform mowing
Ordering Code: 5377M – 107 cm (42 inches) Edge Mulching Cup (42 inches)


Consult the user manual for adjustment procedures for each tractor model. The basic steps to properly balance the mower deck are:

Park the tractor on a level surface.
Inflate the tires to the correct pressure.
Refer to the label on the cutting height button located on the machine console. This label indicates the balancing position of the mower deck and the location of the mower deck set points.
Set the cutting height button on the mower to the correct 6.4 cm position.
Adjust the anti-scalp wheels of the mower as appropriate so that they do not touch the surface of the ground.
Remove the dipstick under the seat.
Using the ports and tool, adjust the trim deck balance from side to side so that the trim balance gauge slides under the left or right edge of the cutter deck at the points designated setting.
The left and right rear adjustment points are under the cutting board edge in the corners of the tray.
Adjust if necessary balancing the deck from front to back.
Loosen the rear nuts on both sides of the front linkage bar.
Turn each of the front nuts in the same way clockwise to raise the front of the mower or counterclockwise to lower it until the gauge slips below the front set point.
The front set point is below the front center of the mower deck.
Tighten the nuts before adjustment is complete.
Return the dipstick to the storage position.
NOTE: The adjustment tool supplied with the tractor is a hexagonal 8mm spherical key, part number M162737. The rounded end allows some offset with the nut when adjusting the cutting deck.


NOTE: In the diagram above, the solid line refers to a tractor with four-wheel steering, and the dashed line refers to a tractor with two-wheel steering.


The four-wheel steering offers significant advantages in terms of handling and cutting capacity compared to tractors with two-wheel steering.

For example, with an X354 Series Select ™ tractor equipped with a 107 cm (42 M) Edge ™ mulching cutting deck (the following numbers are as shown above):

the uncut circular radius is reduced by 66 cm (26 in.) with a two-wheel steering X350 tractor at only
38 cm (15 in), which greatly reduces or eliminates the need to backtrack around trees, shrubs, etc.
Interference between the mower and the tractor wheels is eliminated because they are several centimeters away from the object around which the mowing is performed.
The outside steering angle is reduced, which also reduces the time spent turning and increases the efficiency of mowing.
In addition, mowing in curves around flower beds or other landscaping can be done more comprehensively with a four-wheel tractor.

Designed for tight turns
The four-wheel steering system is designed for tight turns, which allows for better mowing efficiency:

the angles of the casters, camber and rocket pivots are optimized to reduce steering effort, especially during a transition between a straight line and a turn.
The steering geometry was designed using three-dimensional (3D) modeling, for the four tires to work together.
Sealed ball bearings are used on the torsion shaft and rear fuzes to reduce friction.
Reduced ground clearance (less than 25.4 mm [1 “] at the rear) reduces wear and variation in parallelism.
Designed for ease of management

Sealed ball bearings are used at the main four-wheel steering system connections to achieve reduced friction, increased service life and reduced maintenance requirements.

The ease of management is an important factor for a pleasant mowing experience:

The wider, 14-inch diameter flywheel offers good leverage for cornering.
The wide toothed sector improves (increases) the sensitivity of the steering.
Improved steering sensitivity reduces steering effort.
Double longitudinal struts help balance steering loads and reduce the risk of steering errors.
The ball joints at both ends of the steering tie rod help to maintain good driving accuracy longer.
The long steering arms improve the mechanical benefits of the steering system throughout the movements.
The steering shaft pivots on a sealed ball bearing at its lower end, close to the pinion gear, to reduce steering effort and allow smooth driving that improves the service life of the steering gear. tractor.
Pivots on the toothed sector on a shaft and not on a ring to avoid meshing and eliminate the risk of seizure.
Pivoting on sealed ball bearings at the upper and lower ends of the toothed sector shaft reduces steering effort and allows for a smooth ride that improves tractor life.
Front steering knuckles are greasable to increase their service life
