Merry Tiller Spare Parts

We have a range of spares for the Type C Major circa 1958 to the 1990 Major, UK Professional, Wizard and Titan. As there are some differences between early and late models it is important to know which Merry Tiller you have got, before ordering spares. Also many Merry Tillers have been modified, engine transplants are common. If your machine has been modified will the standard part fit? Merry Tillers rarely wear out but we list a few of the common consumable and most often lost spare parts. All spares are reproduction unless marked as genuine. Most engine spares are available from your local Briggs & Stratton agent or Gateshead Lawnmowers who have been mending Merry Tillers since the 1970s we do not carry them. No Clinton spares are available.

We do not sell spares to the US or Canada as US and Canadian owners can use the MacKissic dealer network for parts.
