Motor has the shortcomings that torque output is uneven, the working time is short and at high cost, and the resistance to dust effect of brushless motor is bad.
And the rake grass of electronic grass rake mechine is different with the adapted to working environment that loosens the soil, so will appear following situation:
1, it loosens the soil when fixed constant speed revolving speed is high, due to revolving speed height, strength is superfluous, and effect of loosening the soil is uneven, to setting
Standby impact is big, and temperature increases, and the component that is hit is easily damaged；It loosens the soil when fixed constant speed revolving speed is low, since ground is hard, bears
Carry it is bigger than normal, low speed be more conducive to work, loosen the soil effect more evenly.
2, rake grass is carried out when fixed constant speed revolving speed is high, since the soft load of withered grass is smaller, so that the careless effect of rake is good, work
It is high-efficient；Rake grass is carried out when fixed constant speed revolving speed is low, constant rotational speed is relatively low so that harrowing careless inefficiency.
I.e. use grass rake mechine soil-loosening function when, need to harrow careless axis and slowly run, using grass rake mechine rake grass function when, need
Harrow careless axis high-speed rotation.
