Overview

The gear head is the business end of your trimmer, and when it goes bad the whole tool becomes useless. This gear head and blade provides a factory-spec replacement at a fraction of dealer cost. A cutting blade is included, making this a complete kit for brush-clearing tasks. It ships pre-packed with lubricant so you can install and go.

Key specifications

  • Type: aftermarket replacement gear head
  • Pre-greased: yes
  • Material: die-cast aluminum housing with steel gears
  • Includes: brush-cutting blade

Compatibility

Engineered for compatible equipment trimmers and brushcutters with the same shaft diameter and spline count. Confirm your model number against the compatibility listing before ordering, as gear-head bolt patterns can differ across production runs.

Installation notes

Disconnect the spark plug wire for safety. Loosen the clamp bolt or bolts securing the old gear head to the drive shaft and pull it free. Clean any debris from the shaft end, then slide the new gear head on and align the drive splines. Tighten the clamp hardware evenly to the manufacturer’s torque spec. Attach your cutting head or blade, and run the trimmer briefly to verify smooth, vibration-free operation.

Common questions

Q: Will this gear head and 8” blade fit my EGO Power+ PH1400 power head, or is it only for the PH1420 and PS1000?

Yes, this replacement is made for the EGO Power+ PH1400, PH1420, and PS1000 listed in the compatibility details. If your unit matches one of those model numbers, the gear head and 8” blade should fit properly, but it’s still smart to compare the shaft connection and mounting style to your original assembly before installing.

Q: Does the 8” blade come already mounted to the gear head, and what should I check during installation?

The blade may or may not arrive pre-mounted depending on packaging, so plan to verify the blade orientation and all fastening hardware before use. During installation, make sure the gear head is fully seated on the shaft, the fasteners are tightened evenly, and the blade spins freely without contacting the guard or housing.

Q: What maintenance does this gear head need after installing it on an EGO PS1000 or PH1420?

After the first few uses, recheck the mounting bolts and blade hardware to make sure nothing has loosened from vibration. It’s also a good idea to clean off wrapped grass and debris around the gear head after each job, because buildup can put extra strain on the bearings and affect cutting performance.

Before you buy — how to verify fitment

  1. Measure shaft diameter. Common sizes are 24mm, 25.4mm, and 28mm — check your trimmer manual or measure the drive shaft.
  2. Count the splines. The gear head input must match your shaft spline count (typically 7 or 9).
  3. Check output thread. Verify the thread direction and size for your cutting attachment.
  4. Confirm your trimmer model against the compatibility list above.

Frequently asked questions

How do I know which gear head fits my trimmer?

Match the shaft diameter (typically 24mm, 25.4mm, or 28mm), the number of splines (7 or 9), and the thread direction on the output shaft. Check your trimmer manual for these specs.

Can I replace a gear head myself?

Yes. Remove the old head by loosening the clamp bolt, slide it off the shaft, and slide the new one on. Align the drive shaft splines, tighten the clamp, and check for wobble before running.
