Bosch Drive Gearbox Seal Failure

Robot mower is leaking oil or grease from the underside or wheel area.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn wheel motor gearbox seals, Cracked gearbox housing, Overloading on steep slopes, Impact damage to the wheel assembly

Safety: Turn OFF the mower, disconnect it from the dock, and wear gloves.

Identify the source: Tilt the mower carefully and locate whether the leak is from a drive wheel gearbox or the cutting motor area.
Clean the area: Wipe away leaked grease to inspect for cracks or loose screws.
Check wheel play: Wiggle the affected wheel; excessive play suggests internal wear.
Do not continue heavy use: Operating with a failing gearbox can cause complete drive loss.
Replace the assembly: Install a new drive wheel motor/gearbox assembly specified for your Bosch Indego model.
