HTLS-185 Heavy Duty Rotary Tiller

Prep clean seedbeds fast with the HTLS-185 Rotary Tiller, designed for 40–60 HP tractors. With a 73″ working width and a three-position 4″–7″ depth, it pulverizes hard soils and levels beautifully in one pass. CAT I/II three-point compatibility makes hookup quick across a wide range of tractors.

The oil-bath gear transmission drives a laser-balanced 270 RPM rotor carrying 54 boron-steel blades (6 per flange). A free-wheel Comer gearbox and slip-clutch PTO protect your tractor, while the spring-controlled rear cover and front safety curtains manage finish and debris.

The HTLS-185 Heavy Duty Rotary Tiller is built for 40–60 HP tractors with CAT I/II three-point hitch. It delivers a 73″ working width and a three-position, 4″–7″ working depth, giving you the bite and finish needed for seedbeds, orchards, vineyards, and food plots.

Unlike chain or belt designs, the HTLS uses a maintenance-free oil-bath gear transmission that turns a laser-balanced rotor at 270 RPM for smooth, torque-rich tilling in heavy soils. Under the 1/4″ steel hood, flanges spaced at 10″ carry six boron-steel blades each54 blades total on the HTLS-185—individually replaceable or regrindable. The reinforced free-wheel Comer gearbox prevents back-driving when the PTO is disengaged, while the slip-clutch PTO protects your drivetrain.

Setup is quick: adjustable lower hitches align the tiller to your tractor track; the spring-controlled rear safety cover levels and firms the soil; and front safety curtains contain debris. The unit ships largely assembled in a wooden crate; bolt on the 3-point hitch and PTO guard and you’re ready to work.
