The 2653B PrecisionCut frame is designed with all these demands in mind and provides excellent weight distribution and the durability required for the most-demanding terrain. The frame design keeps a low center of gravity while providing excellent visibility to the front cutting units and rear of the machine.
Sit-on-seat (SOS) diagnostics provide aid when starting machine
SOS diagnostics are provided to assist the operator in getting the machine started. The SOS system checks the machine system functions to be sure they are in the proper configuration for starting.
The system functions that must be satisfied to crank the machine are as follows:
Park brake engaged
Mow lever disengaged
Backlap valve disengaged
Forward/reverse pedals in neutral position
The SOS system alerts the operator by flashing a light on the instrument cluster located on the dash of the 2653B PrecisionCut™ if any these conditions are not met.
The battery indicator light flashes a code while the key is held in the start position. There is a label located on the white box control module access panel that advises the operator what functions are not set properly based on the code that is flashing. This label is in both English and Spanish.
White box electronic control module provides onboard electrical diagnostics as standard equipment
White box controller
This controller gives the technician on-board diagnostics as standard equipment, meaning there are no diagnostic tools or plug-ins to purchase separately. No tools are required to access the white box controller. Simply disengage the latch to open up the access panel. This allows the technician to troubleshoot electrical problems while sitting in the operator seat.
The controller has a heartbeat feature to aid the technician in diagnostics. When the LED light in the center of the controller is flashing at a regular rate, it indicates the controller is properly powered up and there are no circuit problems. Each switch or solenoid on the machine has its own LED light on the controller. Input and output functions can be diagnosed by observing the appropriate lights.
When the heartbeat LED light is flashing at an irregular rate, it indicates there is a system fault of some sort. The irregular flashing rate leads the technician to the circuit to start proper diagnostics. These codes can be found on the front of the access panel to the controller. Detailed information is located in the operator's manual and technical manual.
Frame design for a wide stance and low center of gravity for excellent stability
Low center of gravity
A low center of gravity and a wide, 55-in. (140-cm) wheelbase ensure comfortable and safe operation, even in adverse mowing conditions.
Wide 20x10-10 front and 20x10-8 rear turf tires provide excellent traction and stability for superior mowing performance.
Air-restriction indicator with sight glass visually shows if air restriction is present
An air-restriction indicator is standard on the 2653B PrecisionCut™ Trim and Surrounds Mower. The air-restriction indicator has a sight glass with markings that show if service to the air cleaner is required. This air-restriction indicator is the same one used on the 2500B PrecisionCut Diesel Riding Greens Mower.
When the sight glass in the air-restriction indicator shows red, a major airflow restriction in the system needs to be addressed immediately.
Top shield adjustment for clipping dispersal and grass catching
Top shield adjustment
The Quick-Adjust 7 (QA7) cutting unit features an adjustable top shield to either disperse clippings or throw grass deep into the grass catchers. By adjusting the shield closely to the reel, but not touching the reel, the velocity of the grass as it is being ejected from the cutting unit can be increased.
This throws the clippings further out in front of the machine. When mowing without grass catchers, this means better clipping dispersal and recycling of clippings. When mowing with grass catchers, this helps throw grass deeper into the catcher, making sure as many clippings as possible are caught.
The top shield adjustment is an important adjustment that provides for optimum dispersal and catching performance as the reel diameter changes due to wear.
Fixed front roller for less-aggressive attitude at lower heights of cut
Fixed front roller, notches, and numbering system
To minimize possible damage to the grass plant at lower heights of cut, the Quick-Adjust 7 (QA7) cutting unit features a fixed front roller. If a cutting unit becomes too aggressive, the reel is unable to properly present the grass to the bedknife. This results in an impact cut, similar to a rotary mower, rather than a precise scissor action. A fixed front roller creates a less-aggressive bedknife attitude at lower heights of cut by tucking the bedknife closer to the center point of the reel as the rear roller moves for lower heights of cut.
The front roller uses a notch system to lock both sides of the roller into place. This notch system prevents the front roller from moving during lift and lower cycles, maintaining a more consistent height of cut while mowing. The notches also set the desired height of cut range. Numbers on the roller bracket correspond to height-of-cut ranges in the operator manual. Simply line up the number that represents the desired height-of-cut range with the arrow in the cutting unit casting, and tighten the roller bracket into position. All that is left is to then set the final height of cut by adjusting the rear roller.
Front roller parallel/eccentric adjustment
The fixed front roller also features a parallel adjustment on each end of the roller. By using a gauge bar, the front roller can be perfectly squared to the bedknife. This ensures the front roller, rear roller, bedknife, and reel are all operating in the same plane, virtually eliminating any chances for step cutting and providing a consistent cutting height across the cutting unit.
An added benefit of the roller bracket design is the brackets are mounted to the front of the cutting-unit housing, so once the front roller is paralleled, there is no need to re-parallel the front roller when moving the roller to a different notch setting.
Belt-driven rear-roller power brush for quiet performance and consistent height of cut
Rear-roller power brush overall
To promote a consistent height of cut, the belt-driven rear-roller power brush prevents debris buildup on the rear roller of the Quick-Adjust 7 (QA7) cutting unit. In some conditions, the rear-roller power brush may also eliminate clumping by evenly distributing grass that may build up on the rear roller. The bristles of the brush are adjusted close to the roller, but do not touch the roller, and rotate when the reel is engaged, deflecting debris off and away from the roller.
Power-brush clip-mounting system
The housing is easily secured to the cutting unit by a clip system. The same clip is used to secure the power-brush housing to the Greens Tender™ conditioner (GTC) gear case if a GTC is installed, or directly to the cutting unit housing if no GTC is installed. The clip system allows a power brush to be installed on the QA7 cutting unit quickly and easily.
For quiet and reliable operation, the power brush is driven by a cogged belt system. To prevent water and other debris from entering the housing, the housing is also sealed by a gasket to prevent damage to the belt or bearings. An innovative cam design is used to quickly set proper belt tension, and also allows for quick and easy brush removal.
To aid in speed while adjusting the brush clearance, the system moves in unison with the rear roller so the brush does not have to be readjusted when the height of cut is changed. Only the wear of the bristles over time need to be adjusted; no other adjustment is required.
Two 0.63-in. (16-mm) locknuts on each end of the brush system serve as the adjusting point to set the clearance between the brush and rear roller quickly. All it takes is a 0.63-in. (16-mm) wrench or socket to complete the adjustment. Turn the locknuts counter-clockwise to move the brush away from the roller and clockwise to move the brush closer to the roller.
Notch system for easy and precise reel-to-bedknife adjustments
Reel-to-bedknife adjusters on top of cutting unit
The Quick-Adjust 7 (QA7) cutting units feature a quick and easy notch system to maintain proper clearance between the reel and bedknife. The adjustment is performed at each end of the cutting unit for maximum accuracy and precision from side to side. For easy access to the adjustment, the adjusters are located on the top of the cutting unit.
Close-up of reel-to-bedknife adjustment
All it takes to perform the adjustment is one 0.63-in. (16-mm) wrench or socket. As each adjuster tower is turned, each notch can be felt. Each notch represents a reel movement of 0.0005 in. (0.01 mm). This allows for a very fine-tuned adjustment that moves the reel with accuracy and precision. To move the reel closer to the bedknife, turn the adjuster counterclockwise. A clockwise turn moves the reel away from the bedknife.
Simply use the notch system to set the proper reel-to-bedknife clearance of 0.002 in. (0.05 mm), and it is ready to go. This system saves time without sacrificing a premium cut quality for all closely mowed turf areas. Adjustments are so quick and simple they can be performed effectively not only in the shop, but also on the golf course.
An added benefit to the reel-to-bedknife system is that the bedknife is fixed, meaning that when an adjustment is made, the height of cut does not have to be adjusted as a result.
Front and rear roller options to meet virtually any turf condition
The 3-in. (76.2-mm) diameter spiral-grooved front roller with spiral end caps allows more grass to stand up along the entire width of the cutting unit, providing a better quality of cut. This roller is also self-cleaning, reduces material buildup on the ends, and improves the overall appearance of the finished cut.
The unique spiral design will not pick up objects commonly found to clog grooved rollers. More importantly, this roller design does not require a scraper due to its self-cleaning design, which works debris to the end of the roller rather than filling the gaps between the grooves. This maintains a consistent height of cut across a wide range of conditions.
Heavy-duty smooth and grooved rollers are available for the front of the reel cutting units.
Heavy-duty smooth rollers are standard equipment for the rear of the reel cutting units.
Both of these roller options have respective roller scraper kits to minimize debris buildup and maintain a consistent effective height of cut.
