Triplex mowers are some of the most versatile reel mowers around and mow in a wide variety of applications where quality of cut on contours can be a challenge, including:

Greens
Tees
Fairways
Approaches
Surrounds

In these challenging conditions, a triplex mower must be able to handle not only the upward and downward contours, but also side-to-side rolling terrain and perimeter cuts. Contour following is an area where the 2700 and 2750 PrecisionCut™ and E-Cut™ Hybrid Triplex Mowers truly excel.

With its innovative three-axis lift system, the 2700 and 2750 Triplex Mowers are packed full of contour following capability, including:

42 degrees of upward and downward movement (21 degrees upward, 21 degrees downward)
36 degrees of lateral roll movement (18 degrees each direction)
36 degrees of front cutting unit steering (18 degrees each direction)
17 degrees of rear cutting unit steering (8.5 degrees each direction)

All of this built-in capability ensures excellent cut quality on tough contours and tight perimeters.

Cutting unit contour following system

The system consists of a series of ball joints, sealed bearings, and non-metallic bushings, providing excellent reliability and durability. Best of all, the system is completely maintenance free with zero grease points. There are three independent lift cylinders, and the lift/lower valve goes into float when the cutting units are lowered to allow for the contour following system to do its job.

Weight transfer spring

Spring in forward position

Spring in rearward position

An integrated weight transfer spring for each cutting unit helps transfer weight from the cutting unit to the traction unit. These springs do an excellent job in minimizing opportunities for marking and step cutting in turns, providing a high level of cut quality in perimeters. There are two operating positions for this spring: a forward position and a rearward position. In most conditions and applications, the spring will be operated in the forward position. This will transfer approximately 18 kg (40 lb) from the cutting unit onto the traction unit. In more aggressive undulations where quicker contour following response is needed, the rearward position can be used, which reduces the weight transfer by 4.5 kg (10 lb).

Cutting unit steering limiters

The 18 degrees of steering is very important, especially on greens, for maintaining high levels of cut quality in turns and in perimeter passes. The system allows the cutting units to steer as the machine steers, helping to minimize opportunities for scalping while maintaining a consistent height of cut. In combination with the weight transfer springs, the steering system helps provide consistent quality of cut with less opportunities for marking and step cutting in cleanup passes.

Steering limiters disengaged

However, there are some situations where you may not want as much cutting unit steering, such as highly undulating terrain in fairways, surrounds, and approaches. The standard cutting unit steering limiters provide the capability for the supervisor to lock out the cutting unit steering system to reduce the opportunity for uncut strips. This system provides flexibility to limit steering both in the inward and outward directions independently. With the limiters on both sides disengaged, they allow for full steering of the cutting unit. When engaged on the front cutting units (as shown), steering is limited to 9 degrees, or in combination with moving two washers, steering can be completely locked out to 0 degrees. Engaging the steering limiters on the rear cutting unit completely locks out the steering to 0 degrees.

A dual chain attaching system makes sure the cutting unit is square to the turf at all times during the lift and lower cycle and helps to maintain cutting unit stability when mowing hillsides. This can minimize any potential marking on cutting unit drop. The patented position of the lateral roll axis of the contour following system is close to the center of gravity of the cutting unit, keeping the cutting units very stable in transport.
