Roller-chain sprockets, plate wheels, taper-bore drives and hardened-tooth profiles — manufactured to ANSI, BS and DIN standards and engineered for the abrasive, dust-laden conditions of Australian field work.
An agricultural sprocket has one job — transmit torque cleanly between a roller chain and a shaft, season after season, in conditions that punish lesser drives. Our catalogue covers the full standard range plus a deep library of OEM-pattern wheels: simplex through triplex, plate and taper-bore, double-pitch conveyor sprockets, hardened-tooth profiles for high-shock implements, and stainless options for fertiliser and corrosive environments.
Every wheel ships with traceable material certificates, dimensional inspection data, and surface-hardness verification. Specifications are built around actual Australian use — combine harvesters running 14-hour days through the Wimmera, hay balers in 40-degree Riverina heat, sugarcane harvesters in tropical North Queensland.
Six core families cover virtually every agricultural drive scenario. If you have a serial number, an OEM drawing or a worn sample, our engineering team can match it.
The workhorse profile for the majority of agricultural transmissions — combine drives, baler pickups, mower decks, planter row units. Single roller chain engagement keeps mass low and serviceability high.
Two- and three-strand wheels share load across multiple chains, doubling or tripling effective torque without enlarging diameter. Standard fitment for combine threshing drives, large-square baler ram drives, and forage harvester feed rolls.
Lightweight flat-plate construction for low-shock conveyor and elevator drives — grain-handling augers, header chain returns, baler bale-tube conveyors. Lower mass means lower bearing loads and longer service life on long shaft runs.
Bushed sprockets that lock onto the shaft with a single tapered bushing — no key cutting, no grub-screw drift, easy field service. Especially valuable on irrigation pump drives and grain conveyor headshafts where downtime equals losses.
Two-times-standard pitch (ANSI 2040, 2050, 2060) and oversize-roller variants designed for slow conveyor speeds and large attachments. Standard fitment for grain conveyors, baler pickup conveyors and tomato harvester elevators.
For shock-loaded or corrosive duty: induction-hardened tooth profiles (HRC 50-58) for high-impact drives like rotary cutters and stalk shredders, plus 304 / 316 stainless wheels for fertiliser, slurry and effluent applications.

The difference between a sprocket that survives a single harvest and one that runs three is usually upstream — in the steel grade, the heat treatment, and the way the teeth are cut. Here's what we control:
Our sprocket range supplies these eight equipment sectors as direct-replacement parts and as new-build OEM components.
Threshing drives, header drives, clean-grain elevator returns and unloading auger sprockets.
PTO-driven implement sprockets — rotary tillers, mowers, slashers, post-hole diggers.
Row-unit drive sprockets, seed-meter sprockets and bin-fill auger drives.
Centre-pivot drive sprockets, hose-reel irrigator main shafts and pump-jack drives.
Pickup drive sprockets, ram crank drives, plunger drives and forage feed-roll wheels.
Forage harvester chopper drives, silage defacer apron drives, feed mixer auger sprockets.
Power harrow rotor drives, rotary cultivator gang drives, deep ripper conveyor wheels.
Disc mower bed drives, conditioner roll drives, hay rake conveyor sprockets.
Whether you're replacing a worn wheel or specifying a new drive, work through these in order. If anything is unclear, send us your details and our drive engineers will recommend a part number.
Read the chain identification stamped on the side plate (e.g. ANSI 60-1, BS 12B-2). If unknown, measure pitch with a vernier — pitch is the centre distance between two adjacent rollers.
Count teeth on the existing wheel, or calculate from the gear ratio you need — driving wheel teeth divided by driven wheel teeth gives speed reduction. Avoid prime-number tooth counts paired with prime chain links.
Measure shaft diameter, keyway width and depth, and required hub style — pilot bore, finished bore with key, taper-locked, or split-hub for tight installations. Photograph the worn wheel from both sides.
Standard 1045 is fine for most low-shock duty. For rotary cutters, balers, silage choppers and any high-impact drive, specify induction-hardened tooth profile (HRC 50-58) — tooth wear drops by a factor of three.
Around 40 percent of the wheels we ship are made to OEM patterns — replacement parts for discontinued machinery, new builds for Australian implement manufacturers, and one-off custom drives for engineering shops. Our OEM service includes:
