Operation

Introduction

Grooming is performed in the turf canopy above the soil level. Grooming promotes vertical growth of grass plants, reduces grain, and severs stolons, producing a denser turf. Grooming produces a more uniform and tighter playing surface for faster and truer action of the golf ball.

Grooming should not be considered as a replacement for verticutting. Verticutting is generally a more rigorous and periodic treatment that can temporarily damage the playing surface, while grooming is a routine and gentler treatment designed to manicure the turf.

g006671

Figure 26

  1. Grass runners (stolons)
  2. Thatch

Grooming brushes are less intrusive than conventional grooming blades when adjusted to lightly contact the turf canopy. Brushing may be better for the ultra-dwarf cultivars, since these grass types have an upright growth pattern and do not fill in well through horizontal growth. Brushes can injure leaf tissue if they are set to penetrate too deeply into the canopy.

Groomer blades should never penetrate the soil. They are effective in cutting runners and removing thatch.

Because grooming injures leaf tissue, avoid grooming during periods of high stress. Cool season species, such as creeping bent grass and annual blue grass, should not be groomed during high-temperature (and high-humidity) periods in midsummer.

Many variables affect the performance of grooming, including the following:

  • The time of the year (i.e., the growing season) and the weather pattern

  • The general condition of the grass

  • The frequency of grooming/cutting—both how many cuttings per week and how many passes per cutting

  • The height-of-cut setting on the main reel

  • The height/depth setting on the grooming reel

  • How long the grooming reel has been in use

  • The type of grass

  • The overall management program (i.e., irrigation, fertilizing, spraying, coring, overseeding, etc.)

  • Traffic

  • Stress periods (i.e., high temperatures, high humidity, unusually high traffic)

These factors can vary from fairway to fairway. Inspect the mowing area frequently and change the grooming practice as needed.

Note: Using the groomer reel improperly or too aggressively (i.e., too deep or too frequent grooming) may unnecessarily stress the turf, causing severe turf damage. Use the groomer cautiously.

Note: Continue changing the direction of cut whenever you use the groomer. This enhances the effects of the grooming.

Note: Operate the groomer in a straight line as much as possible. Use caution when turning while operating the groomer.

Height-of-Cut (HOC) and Height-of-Groom (HOG) Settings

Use the Height-of-Cut (HOC) and Height-of-Groom (HOG) table to determine the recommended engagement ranges.

Adjusting the Groomer Height

  1. Park the machine on a clean and level surface, lower the cutting units completely to the ground, shut off the engine, engage the parking brake, and remove the key.

  2. Make sure that the rollers are clean and the cutting unit is set to the desired height-of-cut (see your cutting unit Operator’s Manual).

  3. Rotate the quick-up levers (Figure 27) to the ENGAGED position (the handle points toward the front of the cutting unit.

    Important: Use the Height-of-Cut (HOC) and Height-of-Groom (HOG) recommended range table for setting the gauge bar; refer to Height-of-Cut (HOC) and Height-of-Groom (HOG) Settings.

  4. At the end of the groomer reel, measure the distance from the lowest tip of the groomer blade to the working surface (Figure 27). Turn the height adjuster knob (Figure 27) to raise or lower the groomer blade tip to the desired height.

  5. Repeat step 4 at the opposite end of the groomer, then check the setting on the first side of groomer.

    The height setting on both ends of the groomer should be identical. Adjust the height as required.

Changing the Groomer Operating Direction

The groomer has 3 settings: NEUTRAL, FORWARD, and REVERSE. To change the direction of the groomer, turn the knob at the end of the groomer drive box and align the desired position with the adjustment notch.

Testing the Groomer Performance

Important: Improper or over-aggressive use of the grooming reel (i.e., too deep or too frequent grooming) may cause unnecessary stress on the turf, leading to severe damage. Use the groomer cautiously.

Danger

Contact with the reels or other moving parts can result in personal injury.

  • Before making any adjustments to the cutting units, disengage the reels, set the parking brake, shut off the engine, and remove the key.

  • Keep your hands and clothing away from the reels or other moving parts.

It is important to determine the performance of the groomer before putting it into regular use.

  1. Set the main cutting reels to the height-of-cut setting that you would normally use without the grooming reel. Use a Wiehle roller on the front and a full roller on the rear.

    The amount of grass removed is a key indicator in determining the height/depth setting of the grooming reel.

  2. Set each of the grooming reels to the desired height setting.

  3. Examine the test area and determine if the groomed areas produces the desired results. If not, increase or decrease the height of the groomers and make another test pass.

Check the test area 2 or 3 days after the first grooming for general condition and damage. If the groomed areas are turning yellow and brown, and the non-groomed areas are green, then the grooming was too aggressive.

Transporting the Machine

When you wish to mow without the groomer or need to transport the machine, move the quick-up lever to the TRANSPORT position (Figure 29).

Note: This moves the groomer reel into a raised position.
