Limiting The Maximum Forward Speed - Briggs & Stratton FW25 series Setup Instructions

Limiting the Maximum Forward Speed

The operator can control the maximum forward speed of the
unit. The unit should not be adjusted for an overall faster speed
that it was designed for and the speed adjustment bolt should
never be removed from the unit.
1. Drive the mower in an open area to identify the maximum
preferred forward operating speed. Once the speed is
determined, note the location of the forward speed indicator
(A, Figure 23) to the forward speed indicator icons (B).

2. Park the machine on a flat, level surface such as a concrete
floor. Disengage the PTO, engage the parking brake, turn
the ignition switch to OFF, and remove the key.
3. Loosen the hardware (A, Figure 24) retaining the front
handle bar guard (B) in place and tilt the guard forward.

4. Loosen the jam nuts (C) on the adjustment bolt (D).
5. Push the forward speed control lever forward (E) until the
forward speed indicator is located in relation with the forward
speed indicator icon that you identified as your preferred
maximum forward speed.
6. Position the bolt so that it contacts the forward speed control
lever and then tighten both jam nuts.
7. Return the forward speed control lever to the Neutral
position by depressing the neutral return pedals fully.
8. Tilt the front handle bar guard back into place and tighten
the hardware to secure it in place.
Forward Speed Control Lever Operating
Force Adjustment S/N: 2017118254 &
Above
After adjusting the control responsiveness of the drive levers,
it may be necessary to adjust the operating force of the forward
speed control lever.
The amount of force necessary to operate the forward speed
control lever (A, Figure 25) is adjustable so that the operator
can customize it to their operating preference.
The forward speed control lever has a range of adjustment (B)
from the factory preset position of 1-7/8" (4,76 cm) to the
maximum position of 1-5/8" (4,13 cm). These measurements
are taken by measuring the length of the spring.

• To increase the amount of force necessary to operate the
forward speed control lever turn the adjustment nut (C)
clockwise.
• To decrease the amount of force necessary to operate the
forward speed control lever turn the adjustment nut
counter-clockwise.
