A rotary tedder such as the Volto 77 lifts mown forage using several tine rotors driven through a gearbox, throwing it loosely to the rear while turning it over. This brings damp material from the bottom to the top, aerates it and lets it dry more evenly before it is raked into a swath and harvested. The tines sit on pivoting arms guided around a cam track inside each rotor, lifting the crop cleanly off the ground without working it into the soil.
A tedder's size is set by the number of rotors and its working width, which needs to match tractor power and field width. As a trailed or mounted implement, a tedder is subject on public roads to the general rules for wide mounted equipment, in particular on lighting and marking while raised.
On a used machine, what counts is wear on the tines for abrasion and breakage, the condition of the tine arms and their bearings in the cam track, the tightness of the rotor gearboxes against oil leaks, and any distortion in the frame and lifting linkage. The guards and gauge wheels also belong on the checklist. The condition of the PTO drive shaft and its guard tube, along with a look at the mounting brackets on the tractor, round out the inspection.
