Two different versions of the Rotex Avant NT R are available, depending on the cutting width:
- Rotex Avant NT R6 with 6 discs and a 2.45 m cutting width
- Rotex Avant NT R7 with 7 discs and a 2.85 m cutting width
The compact and light-weight load-bearing frame drastically reduces the overhand of the mower with respect to the tractor, optimising weight distribution and making the use in "combination" with rear-mounted mowers more stable.
It is recommended to install Rotex Avant NT R on tractor having azote-operated hydraulic suspension, to keep the cutterbar load on ground always regular and for a better adaption to the ground contour. As an alternative, a spring suspension kit is available (for standard tractors only).
The main transmission boxes feature gears in oil bath and are designed to operate with tractors with PTO at 540 or 1,000 rpm. The control support, with the gears in an oil bath, is made from spheroidal cast iron to ensure maximum resistance to stress during operation and movement, and it is situated behind the first disc to reduce the overall dimensions and facilitate the passage of the mowed forage.
A free wheel and a clutch are also standard features to protect the transmission. This makes it possible to use a simple cardan joint to convey the motion from the tractor PTO to the machine.
Six types of frames with tractor linkage make the Rotex Avant NT R compatible with all the tractors currently on the market.
A central articulated joint allows the machines to oscillate with respect to the coupling (± 5°), adapting to the morphology of the soils on which they are used. A pin makes it possible to lock it during road transfer.
