Abstract

A movable test and demonstration carriage for tractor-powered implements (Figure 1) was constructed mainly for machine demonstrations to the agricultural students at the University of Helsinki. The carriage is provided with a PTO-shaft run by a 3 kW electric motor trough two car gear boxes. The PTO-speeds on different gear combinations are 30—550 RPM (Table 1). For attachment of the implements, the carriage is also provided with a 3-point hydraulic lift, run by the electric motor.
