SECTION 13B. VERTICAL MOWER
GENERAL
Vertical mower attachments are normally used as
replacements for standard reel mowers when thatch
removal and grain control is the primary greens and
fairway care objective.
The vertical mower uses the same lift yoke and reel
motor as the standard reel mower.
There is no grinding or sharpening procedure for verti-
cal blades. Bent blades can be straightened; broken or
dull blades must be replaced.
The vertical mower assembly includes a front roller
assembly and front roller grass shield assembly.
REPAIR AND SERVICE
Normal repairs and servicing of vertical mowers consist
of blade replacement and cleaning and lubricating or
replacement of bearings.
Individual blades are readily removed without removing
the reel from the frame. To replace the blades, back off
the blade clamp nut 0.25 to 0.375 in (6.3 to 9.5 mm).
Pull the spacer next to the blade to be removed toward
the blade clamp nut to disengage it from the locking
lugs on the spacer. Remove the slotted blade from the
shaft. Install replacement blade with the slot in the
blade in the same position as the blade that was
removed and retighten the blade clamp nut 12 to 15 ft-
lbs (16 to 20 Nm). Retighten the clamp nut lock screw
and nut.
NOTE:
When replacing all the blades, starting from one
end rotate each blade 90° in the same direction.
1. Remove the reel motor and disconnect the mower
from the lift yoke.
2. Disassemble and reassemble the cutter assembly
as shown in Figure 13B-1.
