Innovation and Technology Reducing
Greenhouse Gases
3
Briggs Stratton

• World largest engine manufacturer (13 Million
  engines world wide, sales 2.25 Billion).

4
Briggs Stratton

• Home Power Products Unit has developed dedicated
  Propane engines for use in the Home, Office, or
  School.
• When ever loss of existing electric power
  happens.

Briggs Stratton

• Ferris is part of Briggs Stratton Yard Power
  Products Group and Inventors of Independent
  Suspension on Zero Turn mowers.
• Suspension is the perfect complement to the new
  propane technology.

Environmental Concerns for our Industry

• Gasoline is one of the dirtiest and most
  dangerous (behind diesel) for its emissions,
  especially carbon monoxide and NOx a mixture
  of nitrogen and oxides.
• Many cities have banned the use of commercial
  mowers before 100PM on Ozone Action days.

8
Environmental Concernsfor our Industry

• A California Air Resources Board report shows
  lawn mowers statewide emit 8.28 tons of VOCs per
  day. Some cities are requesting the use of
  alternate fuel or electric.
• Lawn and garden equipment users inadvertently add
  to this problem by spilling 17 million gallons of
  fuel each year while refilling their equipment.
• Thats more petroleum than spilled by the Exxon
  Valdez in the Gulf of Alaska.

Advantages of Propane vs. Gas Powered Lawnmowers
10
Environmental Advantages

• Briggs Stratton BIG BLOCK Propane engine
  delivers a minimum of 30 lower harmful
  emissions.

11
Reduced Maintenance Costs per Year

• Propane burns cleaner no carbon build up on
  valves.
• Eliminates the carburetor maintenance due to poor
  fuel.
• Extended oil life means less time changing oil
  and filter.

12
Extended Engine Life

• Propane runs cooler with a vapor system and is
  much safer and cleaner than gas.
• Propane Liquid is -44 degrees.
• The Briggs Stratton Propane Engine is designed
  with special internal components to handle the
  higher octane of vapor and deliver extended life.
  

13
Restricted Mowing Hours During Ozone Action Days

• In Texas alone 48 counties are designated as
  non attainment areas because of their high
  levels of emissions.
• Gas mowers are not allowed to operate until after
  100PM on Ozone Days.
• Austin, Texas has allowed a 5 higher bid on
  mowing contracts for state properties to cutters
  using alternate fuel (Propane).

14
Fuel Loss or Contamination

• With gas the chance of spilling fuel during fill
  up, leaks in the tank or fuel line, and the
  shrinkage caused by theft or bad gas is
  eliminated.
• The Austin Independent School District realized
  almost 20 recovery of fuel after switching their
  fleet of mowers to propane. Loss was due to
  pilferage and contaminated gas.

15
Dedicated Propane Engine

• Engine is designed by Briggs Stratton to run
  on Propane and carries the 2-year commercial
  warranty.
• Not a converted gas engine.
• BIG BLOCK 32 HP engine has been EPA and CARB
  certified.

16
Dedicated Propane Engine

• Special safety valve prevents the flow of vapor
  to the engine until oil pressure is detected at
  start up.

17
Dedicated Propane Engine

• Hydraulic oil from the wheel motor used to heat
  the regulator eliminating the possibility of
  freeze up. This is common to many liquid
  delivery systems.

18
Fuel Tanks Designed for Safety

• ¼ inch thick aluminum will withstand even the
  sharpest object. Gas units with plastic tanks
  are not as strong and could rupture.
• Propane tanks are certified for 12 years by the
  EPA.
• Equipped with OPD valve for safety to prevent
  overfilling and left hand threads used to prevent
  use on fork lift trucks.

19
Reduced Fuel Cost for Propane vs. Gas

• Propane is 20-30 less expensive than gas at
  present. Regular gas today is 2.59 per gallon.
  Propane is approx. 2.05 to 2.20 per gallon.
  Some agencies purchase propane in bulk and the
  cost savings is even greater.
• The run time on propane is very similar to the
  same unit running on gas per hour.

20
Reduce our Dependencies on Foreign Oil

• Propane is a Domestically Produced Fuel and is
  obtained through natural gas processing and
  petroleum refining.
• About 90 of the United States Propane supply is
  produced domestically.
• 75 is refined in the state of Texas alone, This
  will help reduce our dependence on foreign oil
  supply.
