Powder Metal Parts for Agricultural & Gardening Machinery
Chainsaws, lawnmowers, tillers, brush cutters and hedge trimmers all share the same ingredients: a small engine or motor, a transmission that turns speed into torque, and a cutting head. The gears, sprockets and bearings inside them are ideal powder metallurgy parts – high volume, complex shape, exposed to dirt, vibration and moisture.
BO Powder Metal manufactures sintered components that keep this equipment running reliably in demanding outdoor conditions.
Chainsaw and Outdoor Cutting Equipment
- Drive sprockets and clutch drums – formed to match standard chain pitches, with hardened working surfaces for long chain life
- Clutch shoes and centres – sintered friction components with stable engagement characteristics
- Chain tensioner parts – small net-shape components that would be costly to machine
- Anti-vibration mounts and fittings – structural brackets in sintered steel
Lawn Mowers and Ride-On Tractors
- Mower deck gears and spindles – quiet-running sintered gears with corrosion-resistant finishes
- Transmission gears and washers – for hydrostatic and gear-drive transmissions
- Blade adapters and hub components – high-strength sintered steel
- Wheel bushings and axle bearings – self-lubricating bushings that survive grass, mud and rain
Tillers, Cultivators and Brush Cutters
- Tiller gearbox gear sets – helical and spur gears designed for high torque and shock loading
- Brush cutter clutch and drive parts – centrifugal clutch components and flexible drive couplings
- Auger and drive components – sprockets, pinions and hubs for soil-working equipment
- Shaft couplings and collars – net-shape parts with integral keyways
Agricultural Machinery
- Seed metering and feeder components – accurately formed pockets and profiles
- Hydraulic pump parts – gear sets, wear plates and cartridge components
- Implement bearings and bushings – oil-impregnated and grease-lubricated variants
- PTO and gearbox internals – sprockets, gears and washers for heavy-duty drives
