New addition to Fendt’s traction management
Fendt’s new VarioPull alters the attachment point of an implement.
It can be adjusted on the move, on a horizontal plane, and brought within 80cm of the tractor’s rear axle. This increases road stability, due to optimum weight distribution. Or the driver can shift the attachment further to the rear, for more drawbar space to make headland turns. VarioPull can be automatically controlled, or conveniently adjusted from the driver’s seat. Previously, the axle load distribution of a tractor with a mounted implement could only be changed by using front weights, wheel weights, and the tongue weight. VarioPull allows reduction of front weights and hence of the tractor weight, which increases fuel economy and protects the soil.
The aim with Fendt VarioPull is to be able to set the ideal load distribution between the axles, by utilising the equipment weight better in terms of traction.
The weight is shifted as far as possible from the rear axle to the front axle, by drawing the coupling point, for example the lower link hook, as close as possible to the rear axle, using a hydro-mechanical locking cylinder. VarioPull is an Agritechnica 2017 silver medal winner for innovation.
The variable adjustment of the axle load allows the inner tyre pressure of both axles to be optimised, for the first time, in combination with Fendt’s fully integrated VarioGrip tyre pressure regulation system (which controls tyre pressure between 0.6 bar ann 2.5 bar within minutes). The ground pressure is also reduced, and the traction power maximised. Reducing front ballast also increases driving safety and comfort on the roads. There is an increase in acreage capacity thanks to less drag, less roll resistance in the field, fewer emissions, and better soil protection. Fendt say VarioPull fits well in their traction management, which consists of the VarioGrip integrated tyre pressure regulator system, the VarioDrive drivetrain system, and Grip Assistant electronic system. Fendt VarioGrip is also now available for stub axle vehicles. Previously, it was only available for flanged rear axles.
Fendt say making the VarioPull system easily and quickly operable for the driver was a key element. The user is always informed of the current position by Fendt VarioPull, and can conveniently adjust this from the driver’s seat in the cab, or optionally via an app. It also makes attaching implements easier and safer.
Fendt’s new VarioPull increases travel stability by altering the attachment point of an implement, on the move, for optimum weight distribution.
