📝 Step-by-Step: How to Select Your Ridge Plough / Bed Former Gearbox
Selecting the correct gearbox for your ridge plough is essential for achieving optimal ridge forming performance. Follow this checklist:
| Step | What to Confirm | How to Determine | Why It Matters |
|---|---|---|---|
| 1 | Required disc/rotor drive Speed | Refer to your ridge plough manufacturer’s manual for the recommended disc/rotor drive operating speed | Together with PTO speed, this defines the exact gear ratio your gearbox needs |
| 2 | Existing Gearbox Identification | Record the brand, model number, and any part numbers from the nameplate of the gearbox being replaced | Speeds up the matching process and ensures dimensional compatibility with your bed forming implement |
| 3 | Working Hours per Season | Estimate your annual operating hours for the ridge plough to determine appropriate service life rating | High-hour operations justify premium bearing and gear specifications for lowest cost per hour |
| 4 | Power Requirement | Match the gearbox HP rating to your tractor’s PTO horsepower output and the ridge plough’s demand | Under-rating leads to overheating and premature failure; over-rating adds unnecessary cost and weight |
| 5 | Rotation Direction | Determine whether the disc/rotor drive on your ridge plough requires clockwise or counter-clockwise output when viewed from the drive end | Incorrect rotation direction will damage the implement or produce no useful work |
| 6 | Tractor PTO Speed | Check your tractor’s PTO specification — standard is 540 RPM or 1000 RPM | Determines the input shaft spline size and the baseline for ratio calculation |
| 7 | Torque Demand | Calculate the peak torque your ridge forming application generates — including shock loads from obstacles or material variations | The gearbox must handle peak torque without activating overload protection during normal operation |
💡 Pro Tip: If you are unsure about any parameter, photograph the existing gearbox nameplate and mounting area and send the images to our team via our contact page. We will identify the correct replacement within 24 hours.

⚙ Fitting Guide: Ridge Plough / Bed Former Gearbox on Your ridge plough
Installing a new gearbox on your bed forming implement is a straightforward process when done methodically. Allow approximately 1-2 hours for a complete replacement using standard hand tools.
Before removing any bolts, take detailed photographs of the old gearbox from all angles — document the mounting orientation, PTO driveline routing, and any shims or spacers. Then drain the gear oil into a marked container and dispose of it according to local environmental regulations.
Complete a first-service at 10 operating hours: retorque all fasteners, change the break-in oil and replace with fresh oil of the specified grade, inspect seals and breather, and confirm the disc/rotor drive connection remains tight. This early service removes any metallic particles generated during initial gear run-in.
Ensure the ridge plough is fully supported and cannot roll or tip. Shut down the tractor, remove the key, and disconnect the battery if working near electrical components. Lower all hydraulic implements to the ground. Put on safety gloves, steel-cap boots, and eye protection before beginning any work.
Mate the gearbox output to the disc/rotor drive input. If using a flanged connection, align the bolt holes and use grade 8.8 or higher fasteners torqued to specification. If keyed or splined, confirm the coupling seats fully before applying locking hardware. Verify zero binding by hand-rotating the assembly.
Charge the gearbox with the specified volume and grade of gear oil. Do not overfill — excess oil causes churning, overheating, and seal pressure. Install the fill plug with thread sealant if required. Check that the breather vent is clear and properly installed.
Lift the new Ridge Plough / Bed Former gearbox and slide it onto the mounting flange. Ensure the housing is oriented correctly (check your reference photos from disassembly). Start all mounting bolts by hand before tightening any of them. Apply final torque using a calibrated torque wrench — refer to the torque specification card included with your gearbox.
Separate the PTO driveline and the output connection to the disc/rotor drive. Mark the orientation of the gearbox on the frame before removal. Use an appropriate lifting device (the gearbox may be heavier than it looks). Remove mounting bolts working from the outside in, then gently pull the gearbox away from the mounting surface.
Apply a thin coat of lithium grease to the input shaft splines. Engage the PTO driveline, confirming the splines mesh fully and the safety collar locks into position. Check the driveline angles: measure with an inclinometer if possible. Angles above 15° require a CV (constant velocity) joint upgrade to prevent vibration damage.
