The AA90 by Annovi Aldo, a high performance snowthrower

The standard equipment for the AA90 snowthrower in the new range designed and built by Annovi Aldo in Corlo di Formigine near Modena includes an adjustable hydraulic chute deflector, hydraulic chute deflector rotation of 240º, double support slides, a reduction unit with double 1000 rpm power takeoff right/left for connection with front and rear lifting system and an automatic limiting device right/left snow removal machine as well as a propeller shaft with a bolt torque force limiting device and a lifting system with 2nd category connections. This wealth of equipment was designed for snow clearance in deep winter conditions.

This machine is built of stainless steel to counter wear and fatigue and mounts an oil-bath transmission without chain, a choice hit on by Annovi Aldo technicians for reducing maintenance to a minimum. Moreover, the AA90, making its debut at the Agritechnica 2015, is fitted with automatic limiting for both auger arms and an elastic coupling on the gear box input with a conical gear. The protection of the throwing fan is, on the other hand, located on the cardan shaft safety bolt and is replaced by a maximum valve for a hydraulic transmission.

Overall, the AA90 Series is made up of as many as eight models with tractor power requirements ranging from the minimum of 100 hp to a maximum of 250 hp and with width of clearance from 2300 mm for the basic model to 2900 mm for the top of the range.
