sure settings must be made after the
assembly is complete, such as for a
hydraulic motor on a track drive.
Schematics are essential
Hydraulic schematics are essential for
troubleshooting systems. Unfortu-
nately, they are not as readily avail-
able as they were in the past. This
scarcity is often brought on by
variations in systems for machines.
However, in support of the manufac-
turer, it is also necessary for the repair
technician to have pressure gauges

available in order to test circuits and
readjust limit pressures. Most farm
shops do not maintain sets of pres-
sure gauges for setting pressures.
In the last three years we have seen
great strides in controlling planting
depth, seed depth and soil firming
pressure. These types of controls
become especially challenging where
corn, wheat or beans are being
planted into high residue soil cover.
Seeding control-device combina-
tions are becoming so numerous and
sophisticated that individual combi-
nations of hydraulic control systems
are just not readily available. Thus,
unfortunately, no standardized
hydraulic schematic is likely to
become available for common use in
Ontario or elsewhere.
Staying on top of rapid change
It is imperative that at least one mem-
ber of every farm team that is operat-
ing planting and/or harvesting
equipment take courses or find other
The variety of planting and firming equipment options available is
very extensive.
