means of becoming technically
confident in the design and mainte-
nance of hydraulic systems.
Fortunately or unfortunately,
many sophisticated hydraulic systems
are operated by sophisticated electri-
cal systems. Added to those electrical
systems is the GPS system that auto
steers the planting tractor or the
combine.
How much progress have we made
in the last 20 years? Note in the
planting picture on page 47 that no
row marker system exists. GPS
steering systems have obtained the
capability to bring a tractor or
combine back on the adjacent pass
with accuracy to a few centimetres.
I hope that farm-equipment-dealer
service staff are continually updated
on servicing the latest in planting and
harvesting equipment. There is, and
will be, a great need for their services
in the next 10 years. Possibly one of
their challenges will be to provide
service schools or workshops for

Training workshops can be a very
effective means of sharing informa-
tion if the leaders and participants are
both willing to share their expertise
and experiences.

The goal was to create the most heavy-duty, versatile tractor in its class. So there’s more power for greater lift capacity and pulling heavier implements. Yet it’s nimble enough to maneuver through any operation, making it ideal for hay, dairy, livestock and municipal duty.
