Looking for hammers to replace flails on Chinese manufactured mower model number 1JH 2200.
Dimensions: Top (fitting space to mower) 44 mm; Length (top to bottom) 120 mm; Bottom 50-65 mm; Top hole (attachment bolt diameter) 20 mm.
Can work with hole diameter slightly less than 20 mm as can be drilled out.
Need a hard alloy which is durable as hammers may be required to cut occasional hardwood branches up to 50 mm diameter.
If unable to supply hammers then will consider replacing with flails as per manufacturer.
Can take up to 1000 units.
