This document discusses the benefits of Ferris independent suspension for ride-on lawn mowers. It outlines seven key benefits: 1) increased productivity through longer legal operating hours due to reduced vibration, 2) improved accuracy since all wheels remain on the ground, 3) enhanced safety since braking wheels stay on the ground, 4) better cutting quality since the deck floats level, 5) reliability through a 4-year warranty on suspension parts, 6) uniqueness as Ferris is the only manufacturer that offers independent suspension, and 7) extended chassis life through reduced stress. Independent suspension keeps mowers stable and reduces vibration to allow for longer, safer, and more productive use.

The Benefits of Ferris Independent Suspension

2. The overview

3. There are seven key points (sweet spots) to
consider when assessing Ferris’ independent
suspension.
They are summarised in the following slides
and covered in detail later in this course.
The Seven Sweet Spots

4. 1 Productivity
• You can mow for longer, legally

11. Productivity

12. The Health & Safety Executive (HSE) stipulates
how long a machine can be used each day
based on how much vibration it generates.
Two vibration measurements affect mowers:
• Whole Body Vibration (WBV)
• Hand Arm Vibration (HAV)
Lower vibration, longer hours

13. Independent suspension dramatically reduces
Whole Body Vibration.
By reducing vibration, Ferris ride-on mowers
can legally be used for longer than many
other mowers.
Lower vibration, longer hours

14. Local Authorities are especially conscious of
HSE recommendations. It is cheaper and more
responsible to follow HSE recommendations
than face litigation from injured staff.
Lower vibration, longer hours

15. The HSE publish calculators that specify how
long a machine can be used based on its
vibration.

18. The results to focus on are:
• Exposure Action Value (EAV)
• Exposure Limit Value (ELV)
These numbers illustrate the amount of
vibration an operator has been subjected to
during a day’s work.
Proving the point

19. Exposure Action Value (EAV)
• If a mower exceeds this value during a day the owner is
advised to show they have assessed the risk to the
operator and taken necessary precautions.
A mower with independent suspension
vibrates less so it can be used longer before
reaching the EAV.
Proving the point

20. Exposure Limit Value (ELV)
• The operator must stop using a machine once this
value has been reached.
A mower with independent suspension
vibrates less so it can be used longer before
reaching the ELV.

22. Accuracy

23. Independent suspension keeps the drive
wheels on the ground.
Wheels on the ground can steer the mower.
Wheels in the air can’t.
Better steering, more accuracy

24. Safety

25. Independent suspension keeps the braking
wheels on the ground. This can become
critical when loading and unloading mowers.
Wheels on the ground can stop the mower.
Wheels in the air can’t.
Effective braking, enhanced safety

26. Cutting quality

27. The cutting deck floats with the wheels not
the mower’s main chassis.
As the wheels follow the terrain, so does the
cutting deck.
Floating deck, better cut

28. Reliability

29. All new Ferris ride-on mowers have a 4-year
warranty on the independent suspension
parts.
This covers the lifetime of most Local
Authority contracts.
This is in addition to standard warranty.
4-year warranty

30. Unique

31. Ferris is the only manufacturer to offer all-
wheel independent suspension.
If you want the advantages independent
suspension brings, there’s only one option.
Only with Ferris

32. Chassis life

33. All-round independent suspension extends
the working life of a mower by reducing three
types of chassis stress:
• Torsional stress from uneven ground
• Jolts from holes, bumps and kerbs
• Vibration from general use
Less vibration, longer life
