Tractor sprockets drive the chain mechanisms in PTO-powered implements, front-end loader chain drives, track-type tractor undercarriage systems, and auxiliary equipment chains. Australian agricultural conditions — extreme heat, red dust, crop residue, and seasonal peak loading — demand sprockets with hardened teeth, corrosion protection, and robust construction. We supply tractor sprockets in ANSI #40–#80 and ISO 08B–16B with zinc or zinc-nickel plating for outdoor durability.

✅ Zinc-plated as standard — inferior sprockets ship bare steel, rust within weeks outdoors.
✅ HRC 40-50 hardened teeth — handles dust abrasion. Unhardened teeth wear rapidly in sandy conditions.
✅ Precision bore for vibration-free PTO operation — loose bores damage tractor shafts during peak harvest.
Tractor sprockets are located on PTO-driven implement shafts, front-end loader chain drives, and track-type undercarriage drive systems. The sprocket on the PTO output shaft or implement gearbox engages roller chain to drive seed drills, fertiliser spreaders, slashers, and other chain-driven attachments. In tracked tractors, the drive sprocket engages track links to propel the machine.
Key locations: PTO output, implement drive shaft, loader chain, undercarriage. 功能： Transfer engine power to agricultural implements and ground drive.
OEM： Compatible with John Deere*, Case IH*, New Holland*, Kubota*, Massey Ferguson* tractor and implement chain drives.
*仅供兼容性参考。
选择： Match chain pitch → measure shaft bore → tooth count for speed → zinc for outdoor.
安装： Disengage PTO → remove implement chain → swap sprocket → align → tension → lubricate → test at low PTO speed.
Issues: Rapid wear = dust ingress (improve guarding). Chain jumping = elongated chain (replace both). Noise = dry chain (lubricate). Vibration = loose bore (check keyway fit).
Moree, NSW: “Zinc-plated #60 sprockets on our JD seeder. Survived two dusty seasons. No rust.” ★★★★★
Dubbo, NSW: “#50 on our feed mixer. Hardened teeth handling grain dust abrasion. Good value.” ★★★★★
Toowoomba, QLD: “Replacement sprockets for our Case IH implements. Dimensional match was perfect.” ★★★★☆
Geraldton, WA: “#80 on our front-end loader chain. 4140 steel handling the shock loads.” ★★★★★
Murray Bridge, SA: “Bulk order for our fleet. Consistent quality across 50+ sprockets.” ★★★★★
