MASSEY FERGUSON 410 Operators Instruction Book page 39

Running-in
A gradual running in of a new engine is not necessary.
Prolonged operation with light loads during the early
life of the engine is not recommended. DO NOT
operate the engine at high speeds without a load.
The following precautions should be taken during
the running-in period:
1. Experience has shown that the first 50 hours of
tractor operation have a significant effect on the
performance and life of the engine. From new, the
tractor should be engaged in work which will load
the engine as near as possible to full working
conditions.
2. Use low gear when pulling heavy loads.
3. During the running-in period, check frequently the
tightness of all screws, bolts, nuts, etc.
4. To ensure proper clutch life, care must be taken
to bed-in the friction plates properly. During the first
50 hours a careful watch must be kept on the clutch
pedal free travel, which should be adjusted as soon
as the pedal travel decreases.
Use of the travel speed chart
A typical travel speed chart is illustrated in (Fig.
46&47). The following instructions should be applied
to the chart on the instrument panel or fixed to the
tractor. Used in conjunction with the tachometer, the
travel speed chart performs two basic functions:
1. Checking the tractor ground speed when traveling
in a speed limited area.
2. Establishing the correct gear and engine speed at
which to operate in order to comply with the
requirements of certain PTO driven implements, e.g.
spinner broadcasters or sprayers, etc.
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 horizontal bar
indicates the point within each ground speed range
at which the PTO shaft will be operating at 540 rpm
(engine set at 1685 rpm). 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, 1st 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
rpm. The 540 pto engine speed is 1685 rpm for Live
PTO. If the tractor has IPTO, the engine speed is
1789 rpm for the 540 pto speed.
5. Example of use:
Require 540 PTO speed at 8 kph (5 mph) road speed.
Set engine speed to 1685 rpm, on the chart select
the horizontal bar where the small inverted arrow is
opposite, or close to the 8 kph (5 mph) road speed,
in this case it is the bar for 5th gear.
NOTE: Refer to the speed chart on your tractor for
the correct gear and speed range.
