Mowing - Cylinder Mowers

Cylinder mowers

Cylinder mowers have a cutting action which is similar to a pair of scissors. It therefore provides
a clean cut without tearing the grass. There are two working parts to the cutters - the cylinder and bottom blade.

The blades of the cylinder are made with a spiral twist to ensure a clean cut and lessen damage from any objects hit by the machine. The blades are connected by rivets or welding on a series of flanges to the centre shaft. A rapidly revolving cylinder with 5 -7 blades or more provides the best cut. Chains, belts or gears may drive the cylinder.

The bottom blade should be strong but not too thick to prevent a low height of cut. The bottom blade is attached to the sole plate. Careful adjustment is required to ensure that the cutting blades wipe the bottom blade without being too tight to encourage wear on the cutting surfaces.

The remaining parts of the cylinder mower include the front and rear roller, the throw plate and the grass box. The rear roller may be cast in one section or divided into two or three to assist with turning.

Adjustments to a cylinder mower

There are several adjustments necessary to a cylinder mower to ensure the best use of the machine. Before carrying out any adjustments all operators should have read the operator’s manual for the particular machine. At all times safety should be considered before any adjustment to a mower. It is necessary to take the following steps:

1. Switch off the engine

2. Switch off the fuel

3. Remove spark plug lead

4. Support the mower securely

5. Do not adjust the mower on the surface (to prevent fuel and oil spillage damaging the turf).
