underside of the mower deck may collect a buildup of grass clippings and dirt, especially when grass is wet or has
high moisture content. This build-up will harden, restricting
blade and air movement and will probably show a poorer quality of cutting. Therefore, it should be removed
routinely. To do this it will be necessary to raise and block the deck, using jack stands or blocks, in the full up
position and scrape the build-up from underneath. Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled personnel. Consult Mean Green Products when assistance is
needed.
Torque Values: WARNING:
Particular attention must be given to tightening the drive wheel lug nuts and
blade spindle bolts. Failure to correctly torque these items may result in the loss of a wheel or blade, which can
cause serious damage or personal injury. Call your Mean Green Products Dealer for assistance.
Torque values are given below:
Ft.-lbs.
Wheel (l
ug) Nuts………65
-75
Blade spindle bolt bottom..30
Lug nuts only -
It is recommended that these be checked after the first 2 hours of operation, initially, every 100
hours and following removal for repair or replacement.
Tires
It is important for level mowing that the rear tires have the same amount of air pressure. The recommended
pressures are: 12 psi in rear tires. Front tires are either no flat tires (do not require air) OR pneumatic tires with the
recommended pressures of 12 psi.
Lubrication
Use SAE multi-purpose grease for front caster spindles and wheel bearings.
IMPORTANT: Recommended maintenance at the beginning of each mowing season and every
50 hours of operation.
Electrical system
This mower operates on a 48-volt electrical system. Refer to the
Electrical
section of this manual for detailed
information.
Mower blade maintenance
Check the mower blades daily, they are the key to power efficiency and well-groomed turf. Keep them sharp, a dull
blade will tear rather than cut the grass, leaving a brown ragged top on the grass within a few hours. A dull blade
also requires more power. Replace any blade which is bent, cracked or broken.
WARNING:
Never attempt to straighten a bent blade by heating, or weld a cracked or broken blade as the
blade may break and cause serious injury. Replace worn or damaged blades.
DANGER:
Never work with blades while key is in the ignition switch. Turn key to OFF position, remove key
from switch and disconnect battery cables by pulling up on
LARGE RED
battery quick disconnect handle in battery
box compartment! Block up mower when you must work under it. Wear gloves when handling blades. Always
check for blade damage if mower strikes a rock, branch or other foreign objects during mowing!
WARNING:
Always wear adequate eye protection when grinding mower blades.
Mower blade removal
Use a 9/16” wrench or socket to remove the 3/8” cap screw
holding the blade to the motor shaft from
underneath. It may be necessary to use a 1-
1/4” channel lock pliers
to keep the blade adapter from turning while
removing blade cap screw.
NOTE:
The blade adapter will come off when the blade cap screw is removed. Touch-
up sharpening can be done with a file. Check the blades for balance following grinding. A commercial balancing
tool is available through most hardware supply stores, or balancing can be done by placing the blade on an
inverted line punch or 1/2” bolt. Blade should not lean or
tilt. Spin the blade slowly, blade should not wobble. If
blade is out of balance, true it up before reinstalling. Lay the blade on a flat surface and check for distortion.
Replace any distorted blade.
