Australian Driveshaft Pty Ltd delivers reliable power transmission solutions for haymaking equipment across Australia’s diverse farming landscapes. In raking operations, driveshafts connect tractor PTO outputs to rotary rakes, ensuring smooth rotation of arms and tines that fluff and windrow cut forage. Finger wheel rakes often operate ground-driven without PTO needs, but rotary models demand robust shafts to handle continuous torque in dusty paddocks from Victoria’s dairy regions to Queensland’s tropical pastures. These components withstand vibrations from uneven terrain while maintaining alignment during turns.
Raking follows mowing in hay production, turning swaths for even drying or forming windrows ready for baling. Rotary rakes excel at gentle handling, lifting material with curved tines to minimize leaf loss in lucerne or oaten hay. Power flows through the driveshaft to gearboxes driving multiple rotors, allowing widths up to 10 meters for large-scale operations in NSW Riverina. Finger wheel designs suit smaller acreages, relying on ground contact for motion, but hybrids and larger rotary units in commercial setups require dependable PTO shafts rated for 50-150 HP tractors common in Australian fleets.
Challenges arise in variable conditions. Dusty Victorian summers accelerate wear on universal joints, while wet Queensland winters introduce moisture risking corrosion. Shafts must accommodate angles up to 35 degrees when navigating contours in hilly NSW tablelands. Telescoping sections prevent binding during lift or transport, with overlap maintained for safety. Overrunning clutches protect against inertia when disengaging PTO suddenly after long rows.
Farmers appreciate shafts that balance durability with ease of maintenance. Grease fittings on crosses allow quick service between cuttings, extending life in abrasive environments. Quick-disconnect yokes speed implement changes, vital during tight weather windows.
One Victorian dairy operator switched to our reinforced series after repeated failures on a 8-meter rotary rake. The upgraded shaft managed peak loads from dense ryegrass without vibration, completing 200-hectare seasons flawlessly. Similar feedback comes from Queensland mixed farms where wide-angle options handle sharp turns in irregular paddocks.
Overall, proper driveshaft selection enhances raking efficiency, preserving forage quality for premium hay markets.

Queensland Haymaking Practical Experiences
Queensland’s subtropical climate shapes unique raking demands. High humidity delays drying, requiring frequent tedding passes where rotary rakes shine. Driveshafts endure heat expansion and dust from dry periods, with sealed joints preventing ingress.
In Burdekin and Wide Bay, large rotary rakes cover vast pastures. Shafts handle prolonged operation at 540 RPM without overheating. Wide-angle capability aids contour following on undulating land.
A Darling Downs producer reported halved downtime after adopting our CV shafts on a twin-rotor rake. Previous standard joints wore quickly in silica-rich soils, but reinforced crosses lasted multiple seasons.
Safety aligns with WorkSafe guidelines, emphasizing full guarding and chains.
New South Wales Regional Applications
NSW Riverina stands as Australia’s hay heartland, producing premium lucerne. Rotary rakes form fluffy windrows minimizing ash content for export quality.
Driveshafts manage variable loads from dense stands. Overload protection via friction clutches prevents damage during stump encounters in older paddocks.
Central West operators favor robust series for trailed rakes pulled by 100+ HP tractors. Telescoping accommodates 3-point height variations.

Frequently Asked Questions
Which driveshaft series suits a mid-size rotary rake?
Series 4 handles most 60-120 HP applications reliably, offering good torque margin for dense forage without excess weight.
How do finger wheel and rotary rakes differ in power needs?
Finger wheel models are ground-driven with no PTO requirement, while rotary styles need robust driveshafts for continuous tine rotation and better fluffing.
What causes excessive vibration in rake shafts?
Worn crosses, mud buildup, or improper overlap commonly contribute—clean regularly and maintain minimum 300 mm engagement.
Should I add overload protection for pasture raking?
Friction clutches prove ideal for variable loads, slipping safely during blockages rather than shearing components.
How frequently grease rake driveshaft joints?
Every 50 hours or before each major cutting, using high-quality lithium grease to displace dust and moisture.
What maximum angle works safely?
Standard joints manage 25 degrees; upgrade to CV for 80 degrees in contoured Australian paddocks.
Are metric tubes compatible with Australian tractors?
Yes, lemon or star profiles fit common yokes—ensure exact cross matching for seamless operation.
How ensure guard compliance down under?
Full enclosure with restraint chains meets AS/NZS requirements—inspect daily for damage.
What leads to early joint failure in hay work?
Dust contamination and dry running accelerate wear—use sealed greaseable kits suited to abrasive conditions.
