3.15 CUTTING MODES__________________________________________________________
1. The mower may be operated in the Fixed Mode or
the Floating Mode.
2. Fixed Mode is generally used for cutting heights
greater than 1 in. (25 mm) and the mower does not
require a front roller unless the terrain is rough and
uneven.
If a front roller is required, the roller should be raised
1/4 in. (6 mm) higher than the rear roller and used for
anti-scalp purposes only.
3. Floating Mode is generally used for cutting heights
less than one inch (25 mm) and a front roller is
required.
If a 2-1/2 in. (63 mm) solid front roller is used, the
cutting height will range from 3/8 to 2-1/8 in. (9 to
54 mm).
If a 3 in. (76 mm) grooved front roller is used, the
cutting height will range from 3/8 to 2-1/4 in. (9 to
57 mm).
4. To convert the mower from Fixed to Floating Mode,
remove hardware (H) from each side of the three
mower frames.
Install a front roller and store hardware (H) for future
conversion to fixed mode.
5. To convert the mower from Floating to Fixed Mode,
assemble hardware (H) as shown and remove or
raise the front roller.

3.16 CUTTING HEIGHT ADJUSTMENT _____________________________________________
1. Raise and lock the lift arms in transport mode.
2. For easier access to the height adjusters on the
motor end of the front reels, Jacobsen recommends
raising the front end of the mower just a few inches
off the ground then, being careful not to damage the
hydraulic hoses, tilt the front mowers 90 degrees,
and tether the mowers together.
3. On the rear mower (center) remove the pin and
collar on the shaft and slide the mower backwards.
4. Always make the reel-to bedknife adjustment
(Sections 3.13 and 3.14) before making the cutting
height adjustment.
5. Select Fixed or Floating Mode and convert the
mower accordingly.
6. Loosen skid mounting hardware (D - Figure 3N)
then adjust the cutting height. (A special tool is
provided with the mowers. A 5/8 in. socket and
ratchet are required).
