a.This should be done with two shims (or spacers) on the bottom and one shim on the top of the
caster support arm.
b.The front-to-rear leveling of the blades should be between level and .25” lower (preferred) at the
front of the blades but never higher at the front.
•
Temporary Height-of-Cut Adjustment: Using the caster shims (or spacers) you can adjust the blades
downward temporarily .5” or 1” below the original coarse setting as described above. This assumes
that the blades are level with two shims (or spacers) on the bottom and one shim on the top of the
caster support arm. With the blades level at this assumed starting point, you should never move all of
the shims to the bottom since that would make the blades higher at the front.
The angle of attack of the blades should always be level or lower at the front. This makes the blade
cut the grass only once and saves fuel and wear on the whole mower. It also allows more efficient
mowing and grass catching or dispersal. If you mow in an area of the country where the lawn is very
thick and spongy you may have to set these two adjustments as they would appear on the grass and
not on a hard surface due to the tires “floating” up on or “sinking” down into the lawn.
•
Fine Adjustment: Adjust the blades equally in five settings up or down 0.25” each in a 1.25” total
range. The shims on the blade bolts are moved from under the spindle to the top of the spindle. If
possible, leave at least one shim at the top and the bottom of the spindle shaft. Using the maximums
and minimums of these methods gives you a total range of 2.75” from 1.75” to 4.5” in eleven distinct
settings. The factory setting is 3” when measured to a hard floor surface at the front of the deck.
6.7 Moving the Mower with the Engine Off
Set the transmission shifter to Neutral and lock the hand levers into the neutral position. The mower
is now free to be moved. When parking the mower set the shifter into First or Reverse depending on
the direction the mower is facing. If the mower is facing slightly downhill, set the transmission into
Reverse. If facing slightly uphill, set the transmission into First. Allow handgrips to remain engaged.
Never leave mower unattended on hills or sloped ground.
6.8 Transporting
Use a heavy duty trailer or truck when transporting the Velke Hydro PG. Block wheels and securely
fasten the unit to the trailer or truck with straps, chains, cable or ropes.
6.9 Loading and Unloading
Use extreme caution when loading and unloading units on/off trailers or trucks. One full width ramp
that extends beyond the rear tires is recommended rather than individual ramps for each side of the
unit. The ramp should be long enough so that the angles between the ramp and the trailer or truck
does not exceed 15 degrees. A steeper angle may cause the mower deck components to get caught
as the unit moves from ramp to trailer or truck. Never attempt to turn the mower around on the ramp.
Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a
ramp.
6.10 Cleaning the Mower
The underside of the mower deck should be checked and cleaned twice daily and more often if the
grass being mowed is lush or wet. The entire mower should be cleaned daily at the end of the work
day. Cleaning should be done with a leaf blower or low-pressure compressed air. Wash with water
only when necessary and do not use a pressure washer or nozzle as the water can enter bearings
and electrical connections causing an electrical short, rust and corrosion. When washing with water,
avoid spraying near the hydro cap and do so when the unit has cooled down. Washing a hot
machine can cause various unseen system damage. If water is used for cleaning, immediately dry it
with a leaf blower or low-pressure compressed air and run with blades engaged for approximately 10
minutes. Once the wash is complete, always lubricate and grease all applicable areas.
