challenging to see, especially at night.
•Use flashing warning lights and turn signals whenever driving on public
roads. Use lights and devices provided with the implement.
◼Comply with state and local laws governing highway safety and movement of farm machinery
on public roads.
◼The maximum transport speed for any Victory implement is twenty mph on paved surfaces and
ten mph maximum on an unpaved surface. Do not exceed. Never travel at a speed that does
not allow adequate control of steering and stopping. Rough terrain requires a slower speed.
Traveling excessively on uneven terrain that causes violent shaking or bouncing will damage
the attachment point on the implement and/or the tractor. This type of damage is not covered
under warranty.
◼Use the following maximum speed - for paved surfaces only:
-20 mph when weight is less than or equal to the weight of the tractor.
-10 mph when weight is more than the weight of the tractor.
◼The use of flashing amber lights is acceptable in most localities. However, some localities
prohibit their use. Local laws should be checked for all lighting and marking requirements.
◼When driving the tractor and equipment on the road or highway at all times under 20 m.p.h.
(32 km/h) use flashing amber warning lights and a slow-moving vehicle (SMV) identification
emblem. Do not exceed 20 m.p.h. (32 km/h). Reduce speed on rough roads and surfaces.
◼Plan your route to avoid heavy traffic.
◼Always install transport locks, pins, or brackets before transporting.
◼Do not drink and drive.

Operator’s Manual Victory FMHDH Series - Page 16 of 52 - Version 2.0
◼Be a safe and courteous driver. Always yield to oncoming traffic in all situations, including
narrow bridges, intersections, etc. Watch for traffic when operating near or crossing roadways.
◼Make turns or go up or down hills at a low speed and gradual steering angle. Ensure that a least
20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow down on a
rough or uneven surface. Always check the tractor’s User manual for proper use on slopes.
◼Use extreme care and maintain minimum ground when operating near ditches or fences. Be
careful when turning sharp corners.
◼Never allow riders on either tractor or mower.
4.7.1 Keep Riders Off Machinery
◼Riders obstruct the operator’s view; they could be struck by foreign objects or thrown from the
machine.
◼Never allow children to operate the equipment.
4.7.2 Practice Safe Maintenance
◼Always work in a clean and dry environment.
◼Lower the implement to the ground, put the tractor in parking mode, turn off the engine and
remove the ignition key before performing maintenance.
4.7.3 Prepare For Emergencies
◼Be prepared if a fire starts.
◼Keep a first aid kit and fire extinguisher handy.
◼Ensure you have telephone numbers for the doctor, ambulance, hospital, and fire department.
4.8 Safety and Health measures when using Hydraulic fluid
Anyone working on installations where hydraulic fluid, lubricating oil, grease, or preservatives are
used must observe the following rules:
◼Avoid prolonged contact of the liquid with the skin. In the event of contact, carefully cleanse
the skin. Wear clothing that is free of this liquid. Also, be careful when eating and drinking
during the operation.
◼Avoid skin contact with liquids over 60°C or hot machine parts.
◼Avoid eye contact; if this happens, cleanse with plenty of water and contact a doctor.
◼Liquid storage must follow official guidelines; pay attention to fire extinguishers and emergency
exits.
◼Permanently remove spilled liquids immediately to prevent them from slipping.
◼Hydraulic liquids should not get into the ground or in surface water.
◼Avoid high-pressure fluids hazards. Escaping fluid under pressure can penetrate the skin
causing severe injury.
◼Avoid the hazard by relieving pressure before disconnecting hydraulic lines.
◼Never try to stop leaks from the system by hand.
◼Have used liquids removed and recycled by specialized companies.
◼Use a piece of paper or cardboard, not body parts, to check for suspected leaks. Wear
protective gloves and safety glasses or goggles when working with hydraulic systems.

Operator’s Manual Victory FMHDH Series - Page 17 of 52 - Version 2.0
◼If an accident occurs, see a doctor immediately. Always treat any fluid injected into the skin
within a few hours.
4.9 Driveline Safety
Agriculture and forestry are very hazardous occupations. Today’s farmer spends long hours close
to increasingly complex and powerful machinery.
◼Everyone from the component supplier and the company that manufacturers and assembles
the machinery to the dealers and ultimately the actual user must keep safety in mind to avoid
accidents.
The following checklist relates to the driveline of agricultural implements, general safety literature,
and the standards published by the American Society of Agricultural Engineers.
4.9.1 Driveline Safety Checklist
Driveline Specifications
The first step toward safe applications is to specify and test the driveline to operate appropriately
under expected field conditions.
◼Specify and test the proper size joints and telescoping parts based on the power required by
the implement, rotation speed, joint angles, shock loads, and expected lifetime.
◼Test the hitch geometry to prevent the driveline from:
•Extending beyond the recommended maximum length.
•Bottoming out.
•Reaching a position that allows universal joints to lock.
•Exceeding the maximum allowable angle for the constant velocity of the universal joints.
You can find information concerning these parameters in all driveline manufacturer’s catalogs.
◼Specify and test telescoping parts to allow the lowest possible thrust loads, considering the
expected working conditions.
◼Specify and test torque limiters to control excessive shock loads.
◼Specify and test overrunning clutches to prevent inertial loads from overpowering the tractor.
Hazard Reduction
The second step in specifying a safe driveline application is to strive to eliminate as many hazards
as possible
◼On a driveline with torque limiting or overrunning devices, specify that this device is positioned
at the end of the driveline near the implement.
◼To implement connections that require bolts or set screws, select and/or supply hardware that
minimizes protrusions. You can find Information concerning these parameters in all driveline
manufacturer’s catalogs.
◼For the tractor's PTO shaft connections, specify a safety type yoke (twist or slide collar) to
minimize protrusions.
◼Provide a proper clearance zone for the driveline operation to avoid damaging the shielding
components.
Some common areas of interference are:

Operator’s Manual Victory FMHDH Series - Page 18 of 52 - Version 2.0
◼Three-point linkage.
◼Extended or eye loop hitch pins.
◼Hydraulic hoses.
Guarding
To not effectively eliminated hazards, provide guarding whenever feasible.
The PTO master, critical driveline, and input connection shield should offer an interactive guarding
system.
◼Provide instructions by labels or manuals. Use the implement only with the tractor’s PTO
master shield.
◼Specify and test an integral driveline shield with end cones that overlap but do not interfere
with the PTO master shield or implement an input connection shield.
◼Provide an input connection shield to interact with the integral driveline shield to guard the
shaft coupling and any torque limiting devices installed on the driveline.
◼Check that all routine driveline maintenance can be done without removing the shields.
Warnings and Instructions
Provide warnings and instructions for hazards associated with the machine. Provide instructions
for proper maintenance and repair.
◼Provide labels on the unit to advise the user of proper hitch dimensions and maximum safe
operating speed.
◼Check that proper danger labels are supplied with the driveline concerning these parameters
may be found in all driveline manufacturer’s catalogs.
◼The operator's manual provides instructions for proper driveline operation, maintenance, and
repair.
◼Advise against using PTO adapters, which may defeat the purpose of the tractor’s master shield
and adversely affect the driveline's performance.
◼Advise the user of locations of genuine original equipment spare parts.
