    Installation and Set Up Chapter 2 2.0 Position the grinder Determine where on a concrete slab the grinder will be located. The reel mounts on top of the grinder. The operator loads and works from the front. Adequate working area must be provided around the reel grinder.

  • Page 7: Leveling The Base

    2.2 Leveling the Base Set the grinder to your desired height. Mount the leveling pads provided in to the four corners of the grinder. With the grinder in its final location, use a good quality carpenters level to adjust the leveling pads until grinder is level.

  • Page 8: Reel Drive Motor

    Again using the level, adjust the foot pads so that the back of the grinder is slightly lower than the front. This will let the reel roll into the fence. 2.3 Reel drive motor Mount the reel drive motor. Clamp it in place. The clamping knobs are ratchet style handles and can be adjusted by pulling out and turning.

  • Page 9: Connecting The Service

    Plug and twist the motor plug into its receptacle on the same side as the reel drive motor is mounted. The reel drive motor is smart wired so that it will always rotate in the correct direction. The cord is only long enough to plug the motor into the side on which the reel drive motor is mounted.
  • Page 10 If you have the optional Digital Readout, plug an extension cord to the transformer plug on the bottom of the back panel. Store your tools in the rack.

  • Page 11: Prepare The Cutting Unit For Grinding

    Preparing to Grind Chapter 3 3.0 Prepare the cutting unit for grinding Clean all dirt, grass, rust, grease, and oil from the mower assembly, especially where it accumulates behind the lip of the bed knife. Inspect for a wavy appearance or condition along the top face of the bed knife.
  • Page 12 Check that the front spacer bar and that the bed knife is not loose. If the frame is loose, it is probably out of alignment. Check the mower manufacturer’s manual to reset alignment. Check the reel for free rotation and examine the reel blades for bad nicks that might indicate a twist or sprung spider.

  • Page 13: Mounting The Cutting Unit

    3.1 Mounting the cutting unit Open the front shield. Place the cutting unit on the reel support rails. Position the reel front to back until the center of the reel shaft is above the center of the grinding stone shaft.
  • Page 14 If you are grinding with the bed knife in place, locate the reel so that the grinding stone will only grind the reel blades and clears the bed knife, front roller, and any other part of the reel. Bring the rear fence up to the rear roller.
  • Page 15 Feed the grinding stone up until it almost touches the reel blades. Move the carriage past the reel support rails and make sure there is adequate clearance between the grinding stone and the reel support rail. If it does not, loosen the two socket head bolts in the front reel support rail and slide the rail back.

  • Page 16: Reel Diameter Tape

    3.2 Reel Diameter Tape™ The Reel Diameter Tape™ measures the diameter of a reel by wrapping around the circumference. It is calibrated so that each inch is 3.142 inches long or pi (π) inches long. This will automatically convert the circumference into a diameter. The Reel Diameter Tape™...
  • Page 17 Locate the zero (0) on the right side or vernier side of the Reel Diameter Tape™. Read the measurement just above the zero. Each large numbered line is 1 inch. Each small numbered line is .1 inches. Each small line without numbers is .025 inches.

  • Page 18: Measuring The Reel

    3.3 Measuring the reel Place the magnet of the Reel Diameter Tape™ on a blade at the left end of the reel. Make sure that the magnet is in far enough so that it will not touch the Reel Diameter Tape™ when you wrap it around.

  • Page 19: Adjusting The Cutting Unit

    Make sure that you wrap it in a straight line so that the end of the tape lines up with the vernier line of the tape. Note the reel diameter, in this case, 4.534 inches. INFO-The tighter and straighter the pi tape is, the smaller and more precise the reading will be.
  • Page 20 Feed the grinding stone up at the large end of the cutting unit while turning the reel until the wheel just touches the reel. You should do this at the same place you took your Reel Diameter Tape™ measurement. While holding the hand wheel, turn the dial until it reads 0.
  • Page 21 You may have to turn the scale on with the blue button. Move the grinding head to the small end of the reel. Infeed the hand wheel the difference in the left and right lawn mower diameters by reading .020 on the hand wheel dial...
  • Page 22 ... or on the Optional Digital Read Out. While turning the lawn mower blades, adjust the front roller until the grinding stone just touches the reel. Lower the fence jack.
  • Page 23 Adjust the rear roller until there is no rock. If the rear roller is fixed and the frame is welded, you may adjust the front roller up to .010 to remove the rock, otherwise you need to adjust the frame. If the rear roller is fixed and the frame is bolted, first adjust the front roller as before.
  • Page 24 Check for rock. Loosen the frame and shield bolts, then twist the frame until there is no rock. Retighten the frame and shield bolts. You can also use either the shim kit or eccentric kit available from the mower manufacturer.
  • Page 25 If you would like to be more precise, you can use the dial indicator and magnetic base. Slide the magnetic base front to back and find the high point on one end of the roller. Set the dial indicator to zero. Find the high spot on the other end of the roller, then adjust the rear roller to remove half of the difference.
  • Page 26 If you have a reel to bed knife adjustment, adjust the roller to remove the rock. Then make your adjustments using the reel adjustments rather than the roller adjustments. Use the optional support stands for cutting units without a front roller. To adjust the cutting unit, loosen the frame or roller mount.

  • Page 43: Mounting The Indexer And Relief Stone

    5.2 Mounting the indexer and relief stone Mount the indexer on the collar with the two captured countersunk screws using the t-handle allen wrench. There are different length blade stops that can be used with different width stones depending on the clearance between the end of the reel and the frame.

  • Page 44: Setting The Relief Angle

    Mount the relief grinding stone. 5.3 Setting the relief angle You must set the relief angle so that the grinding stone does not contact the blade in front of the one being ground. Find the closest blade gap by checking for uneven blade spacing or bent blades.

  • Page 45: Engaging The Indexer

    Adjust the grinding stone down 1 to 2 revolutions of the hand wheel for smaller reels and 4 or more revolutions for larger reels. Make sure that the relief angle does not exceed 45°. This will give approximate the correct relief angle for most reels.
