10.6 ARMREST PIVOT __________________________________________________________
1. Adjust the plunger as required so that the plunger
button stops the armrest at both ends of armrest pivot
slots. The plunger body must not contact the armrest
pivot. Do not use the plunger to increase the pivot
tension.
2. Adjust the clamp hardware to get 2 to 6 lbs. (9 to 26.7
N) of force needed at the visor end of the armrest to
move the armrest. Do not over-tighten the pivot
hardware or leave loose.
10.7 BEDKNIFE-TO-REEL _______________________________________________________
1.
Check the reel bearings for end play or radial play.
2.
Inspect the reel blades and the bedknife to make sure
of good sharp edges without bends or surface
damage.
a
The leading edge of the reel blades must be sharp,
without rough edges and show no indications of
become blunt.
b
The bedknife and the bedknife backing must be
correctly tightened. The bedknife must be straight and
sharp.
c
A flat surface of at least a minimum of 1/16 in. (0.15
cm) must be on the front face of the bedknife. Use a
standard flat file to prepare the bedknife.
3.
If backlapping can not correct wear or damage to the
reel or bedknife, use a grinder to correct the surfaces.
4.
Correct reel-to-bedknife adjustment is very important. A gap of 0.001 to 0.003 in. (0.0025 to 0.0076 cm) must be
kept across the full length of the reel and bedknife.
5.
The reel must be parallel to the bedknife. An incorrectly adjusted reel will lose its sharp edges and can cause
damage to the reel and bedknife.
6.
Grass conditions can change the adjustment.
a
Dry conditions will need a wider gap to prevent temperature increase and damage to the reel and bedknife.
b
High quality grass with a good moisture amount will need a closer gap (near zero).
