BALLAST
The performance of your tractor may
be
improved
if the correct amount of front or rear ballast
is
used to obtain the proper amount of rear wheel
slippage.
(1)
Rear ballast
The amount of rear ballast should permit operation
with approximately
10
to
15
percent slip of rear
wheels. Maximum
drawbar horsepower is available
when operating
in
this range. Check slippage as
follows:
a) While tractor is working, count revolutions
of rear wheel between two marks.
b)
Go back with implement raised and count
rear wheel revolutions between
same two
marks.
C) Compare the two counts. The first should
be
10
to
15
percent larger.
d) Check tire tracks often. With too much
ballast, tread marks will be clear and
distinct, showing no slippage. With too
little ballast, tread marks will be wiped
out by slippage.

Do not ballast tractor to

heavy loads. To extend tire life and avoid exces-
sive wear of power train components, avoid con-
tinuous full-load operation in the lower
gears.

Rather than weighting tractor down to pull
heavy loads, try to reduce load. Pulling
a
lighter load at a higher speed is cheaper and
more efficient.
Use no more ballast than necessary, and
remove ballast when
it
is no longer needed.

WARNING
Installing liquid ballast requires special equipment
and training. Have the job done by a qualified
tire
service store.
A
solution of water and calcium chloride
provides safe and economical ballast.
Used
properly,
it
will not damage tires, tubes, or
rims.
