## Abstract

A method of preparing a log splitter comprising a first beam supporting a moveable blade configured for splitting logs and a second beam extending between two wheels, the method comprising: elevating the first beam in relation to the second beam while the first beam is connected to the second beam by a rigid element that is pin jointed at a first end to the first beam and at a second end to the second beam; rotating the first beam horizontally about a vertical connection until the first beam is oriented perpendicular to the second beam; and attaching a tow bar beneath the first beam and parallel with the first beam.

## Claims

### Claim 1

A log splitter comprising:
a first beam supporting a moveable blade configured for splitting logs;
a second beam extending horizontally between two wheels;
a connector that connects the first beam to the second beam, the connector comprising:
an upper pressure plate operably connected to the first beam;
a lower pressure plate operably connected to the second beam;
a vertical pin passing through a hole in one of the upper pressure plate or lower pressure plate, the upper pressure plate being rotatable about the pin while being in contact with the lower pressure plate,
at least one shoulder plate being rotatably connected about a first axle to the upper pressure plate, and being further rotatably connected about a second axle to the first beam, wherein:
the first beam is rotatable horizontally about the vertical pin between a first position being horizontal and parallel with the second beam, and a second position being horizontal and perpendicular to the second beam;
the first beam is moveable upwards, while connected via the shoulder plate to the second beam, from the second position which is a first distance from the second beam, to a third position being horizontal and a second distance from the second beam, the second distance being greater than the first distance; and
the first beam is vertically rotatable about the second axle between the third position and a fourth position being vertically oriented and perpendicular to the second beam.

### Claim 2 (depends on 1)

The log splitter of claim 1, wherein the upper pressure plate and lower pressure plate each define openings for a receiving a securing bolt for preventing horizontal rotation of the upper pressure plate in relation to the lower pressure plate.

### Claim 3 (depends on 1)

The log splitter of claim 1, wherein the shoulder plate and the upper pressure plate each define openings for receiving a securing bolt for preventing vertical rotation of the shoulder plate in relation to the upper pressure plate.

### Claim 4 (depends on 1)

The log splitter of claim 1, further including a tow bar, and wherein the shoulder plate and the tow bar each define at least one opening, wherein a bolt is inserted in each opening for connecting the tow bar to the shoulder plate.
