The farm jack, also known as a high-lift or a handyman jack, is a multifaceted piece of equipment that is used by farmers and mechanics, as well as construction workers and labourers. This adaptable tool is used in a wide variety of duties and repairs that require winching, heavy lifting, pulling and pushing, and are commonly used for removing fence posts, and tractor and farm work. Farm jacks have a weight limit of 3175kg. and are typically available in 20-inch, 33-inch, 48-inch and 60-inch models.

Inspect the jack and make sure that all moving parts match correctly. Ensure that there are no visible cracks or bends on the handle or the rail. Stabilise the load to be lifted since the farm jack does not stabilise the load.
Place the jack on a solid, stable and level surface that is capable of supporting the weight of the jack, the operator and the equipment that is being lifted.
Pull the ratchet control lever---a crescent-shaped switch on the side of the runner---up until you hear the mechanism click, and the latch engages.
Place the jack's lift nose---a grooved platform on the bottom of the runner---completely under the object you are lifting.
Grip the handle and slowly pump it to raise the load.
Insert a grade 5, ½-inch bolt, not included, through the hole in the lift column---the steel rail---directly below the lifting mechanism once you have raised the load to the desired height.
Prevent shifting by inserting additional supports at the lift point to make sure the load is properly supported.
Lower the lift. First, put the handle into an upright position. Then, move the ratchet control lever to the down position. Slowly pump the handle up and down to lower the load and continue pumping the handle until the load is completely on the ground---the latch will click as the load is being lowered. Clean the jack and store it indoors.
