Yes, we would recommend that both petrol and electric mowers are serviced either at the start of the new mowing season or at the end.
Petrol models do have some additional servicing requirements for the engine (e.g. oil and filter changes).
Your local ALLETT Service Dealer will be able to explain to you more about the different services they offer and how much this will cost.
You can also take in your cylinder cartridge for sharpening when required.
