Operating Tips
Mow When Grass is Dry
Mow either in the late morning to avoid the dew, which
causes grass clumping, or in late afternoon to avoid the
damage that can be caused by direct sunlight on the
sensitive, freshly mowed grass.
Select the Proper Height-of-Cut Setting
to Suit Conditions
Remove approximately 1 in. (25 mm) or no more than
1/3 of the grass blade when cutting. In exceptionally
lush and dense grass, you may have to raise the
height-of-cut to the next setting.
Mow at Proper Intervals
Under most normal conditions you will need to mow
approximately every 4-5 days. But remember, grass
grows at different rates at different times. This means
that in order to maintain the same height-of-cut, which
is a good practice, you will need to cut more frequently
in early spring; as the grass growth rate slows in mid
summer, cut only every 8-10 days. If you are unable to
mow for an extended period due to weather conditions
or other reasons, mow first with the height-of-cut at a
high level; then mow again 2-3 days later with a lower
height setting.
Always Mow with Sharp Blades
A sharp blade cuts cleanly and without tearing or
shredding the grass blades like a dull blade. Tearing and
shredding causes the grass to turn brown at the edges
which impairs growth and increases susceptibility to
diseases.
Mowing Patterns
Change mowing patterns often to minimize aftercut
appearance issues induced by repetitive operation in
only one direction.
Counterbalance
The counterbalance system maintains hydraulic back
pressure on the deck lift cylinders. This counterbalance
pressure transfers cutting deck weight to the mower's
drive wheels to improve traction. The counterbalance
pressure has been factory set to an optimal balance of
aftercut appearance and traction capability in most turf
conditions. Decreasing the counterbalance setting can
produce a more stable cutting deck, but can decrease
the traction capability. Increasing the counterbalance
setting can increase the traction capability, but may
result in aftercut appearance issues. Reference the
service manual for your traction unit for instructions to
adjust counterbalance pressure.

Transporting (Groundsmaster 4700–D
Only)
Use the two rear transport latches for the outer cutting
units when transporting over long distances, rough
terrain, or when trailering.
After Operating
To ensure optimum performance, clean the underside
of the mower housings after each use. If residue is
allowed to build up in the mower housing, cutting
performance will decline.
Note: Lower cutting units to the ground whenever
machine is parked. This relieves the hydraulic load from
the system, prevents wear on system parts and also
prevents accidental lowering of the cutting units.
