General Information Operator’s Manual The Operator’s Manual provides information regarding the operation, general maintenance and maintenance intervals for your Greensmaster 3150. Refer to that pub- lication for additional information when servicing the machine. Check Hydraulic System Fluid The hydraulic system on the Greensmaster 3150 is de- signed to operate on high quality hydraulic fluid.

Towing Traction Unit In case of emergency, the Greensmaster 3150 can be towed for a short distance. However, Toro does not rec- ommend this as a standard practice. IMPORTANT: Do not tow the machine faster than 2 to 3 mph because drive system may be damaged. If machine must be moved a considerable distance, transport it on a truck or trailer.
