Checking and Adjusting HST Neutral Spring (for Dynamic
Braking)
WARNING
• Do not operate if tractor move on level ground with foot off
speed control pedal.
• If tractor moves on level ground with foot off the pedal, or, if
the pedal is too slow in returning to "Neutral" position when
removing the foot from the pedal, adjust the HST neutral
spring.
The HST neutral spring located under the front right side of the
fender can adjust returning speed of speed control pedal.
Since the HST neutral spring tension is weakened, the HST
tension should be checked and adjusted every 100 hours.
1. Checking the HST neutral spring tension : Dynamic braking
- Start the engine and hold the maximum engine speeds.
- Operate the machine on the concrete level ground.
- Shift the range gear shift lever to "High" position.
- Depress the speed control pedal to "Forward".
- Release the foot from the speed control pedal.
- Check the distance between the foot releasing point and the
machine stopping point.
- If the distance is more than approximately 3 m (9.8 feet),
strengthen the HST neutral spring tension so that the machine
will stop in approximately 3 m (9.8 feet) after releasing the foot
from the speed control pedal.
