Country Clipper CHALLENGER D510, Product Manual, Page: 21 / 96

4.8
4.6.4 Travel Speed… Vary ground speed of mower to suite the turf conditions and terrain during the
year. (i.e. slowdown in tall thick grass, on slopes, wet conditions, rough terrain etc.)
4.6.5 Normal Mowing… It is recommended to cut off only 1/3 of the grass blade to maintain a healthy
lawn. When mowing an area for the first time it is recommended to cut the turf slightly higher to
avoid scalping uneven terrain and to avoid unseen obstacles in the lawn. If the grass is taller than
6 inches it may require mowing twice to get the desired quality of cut.
4.6.6 Turf Growth Rate… Turf grows at different rates during the seasonal growing period. Turf usually
experiences the greatest growth rate from early Spring to the start of Summer. During this period
the grass may require more frequent mowing to maintain the desired appearance. As you move
into Mid-Summer, less frequent mowing may be required. If regular mowing intervals cannot be
maintained; mow at a higher cut height and then come back a couple days later and mow at the
desired cut height.
4.6.7 Alternate Cutting Direction… Always alternate the mowing pattern to keep grass blades growing
straight and to disperse grass clippings evenly throughout the lawn.
4.6.8 Keep Blades Sharp… Dull blades and improperly sharpened blades can cause cut quality issues.
See Mower Blade Service for information and details on the proper maintenance of blades.
Transmission Free Wheel Release
4.7 If the mower drive becomes inoperable, the mower can be moved by releasing the “Bypass Valve” on
both transmissions which will allow the mower to free wheel. Bypassing the transmissions permits moving
the mower for a short distance at a maximum of 2 mph (3.2 Km/h) without starting the engine.
4.7.1 The Bypass Actuator can be located under the main frame inside the rear of each tire at the back
of the mower. Activate by pulling the Bypass Actuator tab rearward and then move the tab to the
center of the mower to lock in place via the notches on the tab. Both transmissions must be
bypassed to move the mower. Deactivate by moving the Bypass Actuator tab outward and
pushing forward back to the normal run position.
