The minimum mowing height is the height on the average condition green. In the casethat the undulation of green is substantial, set the mowing height higher lest the lawn beshaved.2) Adjust the front groomer according to the condition of the green before use.* If the groomer blades are set deeper than the ground surface, the shaft may bend.* The front groomer, when it is put too low, will apply an excessive load to the engine andtransmission section, causing malfunction or failure.3) When using the grooming brush, adjust the height so that it will be equal to the mowingheight.The brush will be worn easily when the height is too low.4) [IMPORTANT] Adjustment of front roller heightBring the mowing height gauge into contact with the front and rear rollers (as shownbelow), and adjust the height of the bottom blade.a. Loosen the long nut (1-39) of the roller bracket, and move the front roller up or down withroller adjuster (1-24).b. Position the front roller with the mowing height gauge.c. Make adjustment at right and left ends of the mowing unit.d.

Blade engagementCheck that the engine is at rest before making adjustment.Grind and adjust the blade reel cylinder and bottom blade entirely so that a newspaper willbe cut sharply.Conduct lapping after mowing operation (before adjusting the engagement).1) Check the engine portion of the blade reel cylinder to check which portion is dull. (If anewspaper can not be cut in any portion, put in two sheets of paper to carefully checkwhich portion is dull).2) Connect the lapping machine (RM20A) or lapping bolt (option) to the lapping shaft of themower.3) Rotate the blade reel cylinder in the direction opposite to the mowing direction, andapply abrasive with a brush only to the portion where a newspaper was sharply cut.The portion where a newspaper was not cut is worn away. Do not apply abrasive tosuch portions.The right side (when viewed from the front of the blade reel cylinder) of the blade reelcylinder will be worn away 3-4 times earlier than the left side. When applying abrasive tothe blade reel cylinder, be sure to move the brush from left to right. When the abrasive isa mixture of powder (#200~#400) and oil, mix them at the rate of 1:3 to 4. The gelcompound (option) can be used as it is.4) Keep rotating the blade reel cylinder, and stop rotation when the contact sounddisappears. Put in a newspaper again to check the blade reel cylinder entirely for thesharpness of each portion.5) Repeat operations (3) and (4). When the blade reel cylinder and bottom blade are incontact with each other uniformly, apply abrasive to the blade reel cylinder entirely forfinal lapping.6) After lapping, remove the abrasive with steam, etc.Danger Both blade reel cylinder and bottom blade are edged. Handle themcarefully.Be careful of the fingers, which turn the blade reel cylinder, when cutting anewspaper to check sharpness. Uniformly lap the right and left sides ofthe bottom blade in contact with the blade reel cylinder, and the life of theblade will be maximized.
