How to replace the cutting blade of the GARDENA PowerMax 37 E?

Question

Accepted Answer

To safely replace the cutting blade of your GARDENA PowerMax 37 E mower, start by completely turning off the device and unplugging the power cord from the electrical outlet. This precaution is essential to prevent any accidental start during the operation. Remember to wear protective gloves when handling the blade to prevent cuts.

Gently turn the mower over onto a soft surface or place it on its side while protecting the motor housing to avoid any damage. Locate the blade fixing screw under the cutting deck and unscrew it with a suitable screwdriver, taking into account the washer and spacer. Warning: do not damage the spacer while unscrewing, as it is essential for the balance of the blade. Carefully remove the old worn blade while holding it firmly.

To install the new blade (reference GARDENA 585207001 or 4016-20, DuraEdge™ model), ensure that the inscription "This side to grass" is facing up and visible. Position the spacer, then insert the washer and fixing screw. Tighten the screw to a torque of 15 to 20 Nm – this is crucial for secure fastening without over-tightening and damaging the spacer.

Important: the blades must be replaced at the same time as their fixing system (washer and spacer) to maintain the balance of the mower. An unbalanced blade will cause excessive vibration that can damage the motor or cause injury. After replacement, return the mower to its normal position, plug it in, and perform a test on a small area to check that the blade is working correctly and that everything is securely fastened.
