(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.
