eter, the travel speed chart performs two
basic functions:
1. Checking the tractor ground speed
when travelling in a speed limited area.
2. Establishing the correct gear and en-
gine speed at which to operate in or-
der to comply with the requirements
of certain PTO driven implements, e.g.
Spinner broadcasters or sprayers, etc,.
Fig. 5: Travel speed chart.
To read the travel speed chart:
1. The bold horizontal bars on the chart
represent the ground speed range in
each gear, between the two engine
speeds given in the inset below the
tractor.
2. The small inverted arrow in the hori-
zontal bar indicates the point within
each ground speed range at which the
PTO shaft will be operating at 540 rev/
min (engine set at 1789 rev/min). This
can be related to the road speed in kph
or mph at the top and bottom of the
chart.
3. The numbers on the left of the chart
are the gear ranges, 1 st to 4th in the
low range, 5th to 8th in the high range.
4. The information in the box gives the
engine operating speed range, in this
example, 1500 to 2250 rev/min. The
540 PTO engine speed is 1789 rev/
min.
5. Example of use:
Require 540 PTO speed at 8 kph (5
mile/hr) road speed.
Set engine speed to 1789 rev/min, on
the chart select the horizontal bar where
the small inverted arrow is opposite, or
close to the 8 kph (5 mile/hr) road speed,
in this case it is the bar for 5th gear.
NOTE
Refer to the speed chart on your trac-
tor for the correct gear and speed range.
