Cutting Height - Jacobsen HR 5111 Parts And Maintenance Manual

3 ADJUSTMENTS

3.16 CUTTING HEIGHT _________________________________________________________

Level the front mower before setting the cutting height for
the first time. Do not remove the cutting units from the
tractor to change cutting height.
Cutting height for decks can be adjusted from 1 to 5-1/2
in. (25-140 mm) in 1/2 in. (13 mm) increments. Actual
cutting height may vary somewhat from the heights given
depending on turf conditions, tire variances and other
factors.
Note: When cutting undulating areas, lower cutting
heights may cause scalping. Adjust height accordingly to
prevent turf damage.
1. Park the tractor on a flat, level surface. Raise the
decks until the caster wheels are raised off the
ground enough so caster wheels can be removed
from deck. Place blocks under decks so they are
supported on all sides.
!
To prevent serious injury, lower deck until it is
resting completely on the supports. This will
prevent it from accidentally lowering while making
adjustments. Disengage
parking brake, stop engine and remove ignition
key.

3. Adjust spacers in quantity listed. Store extra spacers
on top of spindle. Always leave one thin spacer
above and below caster arm.
4. For cutting heights 3 in. (76 mm) and below, caster
arms should be assembled to upper set of holes
(A). For cutting heights above 3 in. (76 mm), caster
arms should be assembled to lower set of holes (B).
Note: After setting cutting height, fully lower cutting units
onto a flat, hard surface, stop engine, and measure the
distance from the blade tips to the ground. If the distance
is different from the desired cutting height, make
adjustments as necessary. Cut in a small test area and
make any final adjustments for desired turf appearance.
