(60 Skid-Steer Loader shown)
The motors and chains of the 60 Skid-Steer Loader are
located under the floor panel, in the 18-U.s.-gallon reservoir,
for cooling and lubrication.
(90 Skid-Steer Loader shown)
On the 90 Skid-Steer Loader, the ratio between engine
horsepower,hydrostatic motor sizeand reservoir sizeis such
that the motors have sufficient coolingwithout being placed
in the hydraulic reservoir.The chains are located in 1.5-U.S.-
gallon chain cases for lubrication ("A" above).
The 90 Loader features a T-bar, and the 60 Loader uses
two levers to control the direction and ground speed of the
loader. Two-lever control is necessary on the 60, in order to
allow easy entry and exit of its narrow operator station.
Aneutral start safety switch is provided at the base of the
drive clutch lever. This means that the pumps must be dis-
engaged before the engine will crank.
