Vermeer TM120 8-Disc Trailed Mower – 12 ft Cutting Width, 540 RPM, 2-Point Swivel [TM1423531]

Meet the Vermeer TM120 8-Disc Trailed Mower, a mid-sized trailed disc mower designed for efficient hay and forage cutting. With a 12-ft cutting width, eight-disc Q3^® cutter bar, 540-rpm PTO drive and a recommended 65-hp tractor, the TM120 is suited to operators who need dependable field performance, practical transport dimensions and hydraulic control for lifting, swinging and pitch adjustment. Its 2-point swivel-gearbox hitch configuration, nitrogen-charged hydraulic suspension and heavy-duty frame support productive mowing across a range of hay-cutting applications.

Efficient Cutting Performance

The TM120 uses an eight-disc Q3^® modular cutter bar with 23-in discs rotating at 2,700 rpm. Sixteen blades provide the cutting action, while hydraulic pitch control allows adjustment of the cutter bar angle. The specified cut height is 1–3 in, helping operators set the mower for different field conditions and forage requirements.

A driveline friction-disc clutch provides torque protection, while the standard Quick-Clip^® blade retention system and Quick-Change^™ shear ring are designed to support convenient service and component changes. The cutter bar is backed by a standard three-year limited cutter-bar warranty.

Swivel Hitch and Hydraulic Control

The TM120 is specified with a 2-point hitch and swivel gearbox, compatible with Category II or III N configurations. The swivel gearbox includes a pivoting header gearbox and CV joint, while the hydraulic swing cylinder helps position the mower. A drawbar with swivel gearbox is also listed as an available hitch option for the TM120 model.

Hydraulic suspension is nitrogen-charged, and the mower requires two hydraulic remotes: one single-acting remote for lift and one double-acting remote for swing. The tractor hydraulic system should provide 1,900 psi (131 bar) and 6 gpm (22.7 L/min).
