High-Clearance Jack Speeds High Boy Wheel Swap
Changing wheels on high boy sprayers is time consuming and can be dangerous. High clearance jacks from Dave’s Machine Shop are a lot safer than putting a jack on top of a stack of wood, which is what many farmers do.

    “All high-clearance sprayers come with wide floater tires for pre-emerge application and skinny wheels for in-season spraying,” notes Dave Horn, Dave’s Machine Shop. “With crops at different stages of growth, a farmer or custom applicator can be changing tires twice a day. Our self-contained units make changing wheels fast, safe and easy.”

    Horn developed his high clearance sprayer jack for area farmers and ag retailers. It’s tubular steel with a 2 1/2 by 2 1/2-in. inside leg that slides inside a piece of seamless 3-in. tubing. Four legs provide solid bracing, sinking slightly into the ground and anchoring the jack in most soils.

    “If conditions are muddy, you might want to use some plywood under it,” says Horn. “Otherwise it’s fine by itself.”

    A steel plate at the base of the legs provides a base for a 10-ton or larger hydraulic jack. Horn says he originally tried a design with the jack at the top of the tubing, but it wasn’t as stable.

    “With the jack at the bottom, it’s steady as a rock,” says Horn. “All the weight is transferred straight down onto the hydraulic jack at the base.”

    Fully extended, the 42-in. tall unit stands 70 in. high. It weighs 96 lbs. and is priced at $480 without the hydraulic jack.

    “With my jack, you don’t have to spend time looking for blocks, stacking them or worrying where you put them,” says Horn. “You can do all 4 wheels in the time it used to take to do one.”
