Parts needed for this procedure:

Extended splined insert (right-hand threads)	2
Extended splined insert (left-hand threads)	1
Flange locknut (3/8 inch)	6

Note: You may discard all removed parts unless otherwise stated.

1. Remove all cutting units from the traction unit; refer to your Operator’s Manual.

2. Remove the carriage bolts and locknuts securing the height-of-cut (HOC) brackets to the cutting-unit side plates (Figure 3).

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.

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.

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 23) 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 chart for setting the gauge bar.

4. At 1 end of the groomer reel, measure the distance from the lowest tip of the groomer blade to the working surface (Figure 23). Turn the height adjuster knob (Figure 23) to raise or lower the groomer blade tip to the desired height.

   

   Figure 23

   2. Quick-up lever
   3. Groomer height (HOG)
   4. Number of rear roller spacers (below side plate pad)

5. Repeat step 5 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.

Note: Maximum HOG recommended is half the HOC to 6 mm (1/4 inch) maximum engagement

* Move the groomer front height-of-cut (HOC) bracket to the bottom (cutting unit location) side-plate hole.

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.

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.

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 gives 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.

Service Interval

After the first 100 hours

Every 500 hours / Yearly (Whichever comes first)

1. Clean the external surfaces of the groomer housing.

   Important: Ensure that there is no dirt or clippings on the outside of the groomer housing; if debris gets inside of the groomer it can damage the gearbox.

2. Remove the drain plug on the bottom of the housing (Figure 27).

3. Remove the fill plug on the side of the housing and loosen the air-vent plug on the top so air can pass through (Figure 27).

4. Align a suitable container beneath the oil-drain port to catch drained oil.

5. Tip the cutting unit back onto the kickstand until the drain port is at the bottom to ensure complete drainage (Figure 25).

   

   Figure 25

   1. Remove the drain plug from the drain port.
   2. Remove the fill plug from the fill port.
   3. Loosen the air-vent plug.

6. Rock the cutting unit back and forth to ensure complete drainage. When the oil is completely drained, place the cutting unit on a level surface.

7. Install the drain plug.

8. Use a syringe (Part No. 137-0872) to fill the drive box with 80-90W oil (approximately 90 cc).

   

   Figure 26

   1. Syringe with 80-90W oil
   2. Fill port

9. Install the fill plug and tighten the air-vent plug.

10. Torque all plugs to 3.62 to 4.75 N∙m (32 to 42 in-lb).

Note: Retain all removed parts for later installation unless otherwise stated.

Important: If you have any issues removing the groomer drive box, refer to your traction unit Service Manual or contact your authorized Toro distributor.

1. Remove the cap from the groomer.

2. Remove the clamp bolts connecting the groomer to the drive box (Figure 15).

3. Remove the adjuster pin and cotter pin connecting the groomer drive box to the adjuster arms (Figure 28).

4. Restrain the reel for removal; refer to Restraining the Reel for Removing Threaded Inserts.

5. Install the reinforcement screw (Part No. 1-803022—sold separately) to the internal threads of the groomer drive hex head and torque to 13.5 N⋅m (120 in-lbs) as shown in Figure 28.

6. Remove the groomer drive box from the cutting reel by turning the groomer drive hex-head (Figure 28).

   Important: If the groomer drive box is installed on the right side of a cutting unit, turn the groomer drive hex-head counter-clockwise (right-hand thread) to remove the drive-box shaft from cutting unit.

   Important: If the groomer drive box is installed on the left side of a cutting unit, turn the groomer drive hex-head clockwise (left-hand thread) to remove drive-box shaft from cutting unit

   Important: You must use a 6-point socket with heavy wall.

Clean off the grooming reel after using it by spraying it with water. Do not direct the water stream directly at the groomer bearing seals. Do not permit the grooming reel to stand in water so that the components rust.

Inspect the grooming-reel blades frequently for damage and wear. Straighten bent blades with a pliers and replace worn blades. When inspecting the blades, check to see that nuts on the right and left blade-shaft ends are tight.
