Not Sure Which PTO Gearbox You Need?
Selecting the correct agricultural gearbox is critical for equipment longevity and operational efficiency. Our engineers can help you navigate gear ratios, torque ratings, input/output shaft configurations, and mounting compatibility. Whether it's a gearbox for rotary cutters, a rotary tiller gearbox, or a speed increaser for hydraulic pumps — we match you with the right solution every time.
What to Prepare Before Ordering a PTO Gearbox
Providing complete technical information upfront accelerates the quotation process and ensures you receive the ideal agricultural gearbox solution. Here are the key details our engineering team needs:
Application & Equipment Type
Specify the machine your PTO gearbox will power — rotary cutter, flail mower, round baler, rotary mower, fertilizer spreader, post hole digger, rotary tiller, wood chipper, feed mixer, or manure spreader. Different applications demand specific gear configurations, seal types, and housing materials.
PTO Speed & Gear Ratio
Standard tractor PTO speeds are 540 RPM or 1000 RPM. Indicate your required input speed, desired output speed, and the gear ratio needed. For PTO speed increaser gearboxes or pto gear reducer applications, exact ratio calculations prevent costly mismatches.
Torque & Power Requirements
Define the horsepower (HP) or kilowatt (kW) rating your pto drive gearbox must transmit. Include peak torque loads for heavy-duty operations such as stump cutting, hay baling, or soil tillage. Overloading a hydraulic PTO gearbox without adequate safety margins leads to premature failure.
Mounting & Shaft Details
Provide mounting bolt patterns, shaft diameter, spline count (6-spline, 21-spline, or 20-spline), shaft rotation direction, and housing orientation. If replacing an existing unit, share the OEM model number or a photo of the nameplate for accurate cross-referencing.
What Our Customers Say About Our PTO Gearboxes
From tractor PTO gearbox replacements to large-scale OEM supply of agricultural gearbox assemblies, our clients trust us for quality, precision, and responsive service.
We ordered 200 units of rotary cutter gearbox assemblies for our equipment line. The quality matched our original specifications perfectly, and delivery was two weeks ahead of schedule. Excellent gearbox for rotary cutters — will reorder for the next production run.
Their flail mower gearbox replacement saved our fleet from extended downtime. The engineering team helped with cross-referencing our old Italian gearbox part numbers and suggested an upgraded seal design. The gearbox noise and vibration levels are noticeably lower than our previous supplier.
We needed a custom hydraulic PTO gearbox with a speed increaser for hydraulic pumps on our irrigation systems. Ever-power engineered a solution that runs 15% more efficiently than the German brand we previously used — at half the price. Strongly recommend their agricultural gearbox engineering team.
