Abstract
A gang mower comprises a number of individual reel mowers ganged together, each reel being driven by an electric motor from an electric power source, such as an alternator, associated with the mower. The alternator is typically driven by the same motor that propels the gang mower along.
Claims7
A gang mower suitable for being propelled along the ground by an engine driven vehicle, including:
- (a) a frame connectable to move with said vehicle;
- (b) an alternator assembly securable to said vehicle, said alternator being couplable with said engine of said vehicle, whereby said engine speed and alternator output voltage vary together;
- (c) a plurality of cutting reel assemblies attached to said frame said cutting reel assemblies experiencing a load which varies with respect to the ground speed of said vehicle;
- (d) each of said cutting reel assemblies including a cutting reel mounted between and supported by a pair of wheels;
- (e) a single electric motor mounted on each cutting reel assembly in driving engagement with the corresponding cutting reel;
- and
- (f) power supply cables connected to each of said electric motors from said alternator to supply electrical power generated by said alternator assembly whereby when said engine speed decreases, decreasing said vehicle ground speed and the voltage from said alternator, the load applied to said cutting assembly decreases to correspondingly lower voltage requirements for said motor.
