•IMPLEMENTS: I have explained that Deflectors, Chain Guards, or Solid Skirts must be installed and maintained in good repair.
•DRIVELINES: I have made certain that all driveline, gearbox, and other shields are in good repair and fastened securely in place to prevent injuries from entanglement or thrown objects.
•HYDRAULIC MACHINES: I have explained the necessity of using clean hydraulic oil, changing filters as
instructed, stopping leaks, damage caused by operating with over-heated oil, caring for hoses, using hoses of
proper rating, maintaining the specified operating pressure and the potential hazard of oils penetrating the
skin.
•FOLDING-TYPE IMPLEMENTS: I have explained that it is not possible to guard against thrown objects when
the head is lifted off ground and that operator is responsible to watch out for persons in the area. I have
explained that the lifted mower head or boom can contact overhead obstructions with damage to cables and
telephone lines and possible injury. I have explained that the extended head or boom or retracted boom can
contact power lines resulting in electrocution, injury or death and that operator is responsible for keeping clear
of such hazards.

ROTARY MOWERS CAN THROW OBJECTS 300 FEET OR MORE UNDER ADVERSE
CONDITIONS.
TO AVOID SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS FROM THROWN OBJECTS:
•KEEP bystanders 300 feet away
STOP MOWING IF PASSERSBY ARE WITHIN 300 FEET UNLESS:
•All THROWN OBJECT SHIELDING including, Front and Rear Deflectors, Chains Guards, Steel Guards, Bands,
Side Skirts and Skid Shoes in place and in good condition when mowing.
•Mower sections or wing are adjusted to be close and parallel to ground without exposing blades.
•MOWING AREA has been inspected and foreign materials and debris have been removed.
•PASSERSBY are inside enclosed vehicle.
INSPECT AREA FOR POTENTIAL THROWN OBJECTS BEFORE MOWING:
•REMOVE debris, rocks, wire, cable, metal objects and other foreign material from area.
Wire, cable, rope, chains and metal objects can be thrown or swing outside deck with great velocity:
1. MARK objects that cannot removed.
2. AVOI D these objects when mowing.
HIGH GRASS and WEED AREA INSPECTION:
•INSPECT for and REMOVE any hidden large debris.
•MOW at Intermediate height
•INSPECT and remove remaining debris
•MOW at final height.
MOWER THROWN OBJECT SHIELDING:
•KEEP all thrown object shielding including, Front and Rear Deflectors, Chains Guards, Steel Guards, Bands, Side
Skirts and Skid Shoes in place and in good condition when mowing.
•DO NOT OPERATE with any thrown object shielding missing, damaged or removed.
RIGHT OF WAY (Highway) MOWING
•USE DOUBLE CHAIN GUARDS for highway, right-of-way, parks or greenbelt mowing or all other mowing where
human dwellings, vehicles, or livestock could be within 300 feet of the mower.
•No shielding is 100% effective in preventing thrown objects. To Reduce Possibility of Injury:
1. MAINTAIN MOWER SHIELDING, side skirts, skid shoes, and blades in good operational condition,
2. RAISE CUTTING HEIGHT to 6 INCHES minimum,
3. INSPECT AREA thoroughly before mowing to REMOVE potential THROWN OBJECT HAZARDS,
4. NEVER ALLOW BLADES to CONTACT SOLID OBJECTS like wire, rocks, post, curbs, guardrails, or ground
if implement driveline does not match Tractor PTO shaft:
•DO NOT USE PTO ADAPTER.
Using a PTO adapter can cause excessive vibration, thrown objects, blade and implement failures by
doubling operating speed. Increased working length exposing unshielded driveline areas. PN PE01
