Rubber Track systems in agriculture

1980ies 2010

� Increased belt lifetime

� Increased speed level

� Increased comfort level

� Increased pulling forces

� Increased machine weight

� Increased soil sensitivity=>

� Established technology

� Increased volume

� Increased application areas


31/01/1310

Agenda



Why tracks ?

� High contact area and very low ground pressure� Lower transport width in relation to contact area� High level of soil protection goes along with higher yields� Low slip capabilities in up hill applications� Secure staying on track in side hill operations� Harvesting capability also in heavy duty conditions� Higher seasonal performance� Optimized comfort with full suspension� Smoothness for header application

Dominator

LSD

A machine on duals (both 680 tires) followed by a 700 tire causes similar soil deformation compared to tracks

A Dominator (11 t) causes similar soil deformation as a track machine at 33 t

Influence of lugs limited to top 100 – 200 mm

Different longitudinal soil deformation shown for track (backward) compared to wheel (forward)

Track undercarriages - state of the art

Friction drive systemCLAAS, AGCO – Challenger, JD-T Series et al.Suspension at the interface Track UC vs. Machine

Positive drive systemSnowmobiles, Defence, Retrofit et al.Suspension of Midrollers via rubberblocks


1996: GEN 0a

Main features:

- Friction drive system- one midroller- pneumatic tyres as driverand idler

- wheelbase app 1200mm- paylod 12t per axle- no suspension- track frame structurewelded


1997: GEN I

Main features:

- Friction drive system- two midroller- stamped rubberized wheelsas driver and idler

- wheelbase 1825 mm- payload 20t per axle- no suspension- track frame structure welded


2005: GEN II

Main features:

- Friction drive system- two midroller- stamped rubberized wheels as driver and idler

- wheelbase 1825mm- payload 24t per axle- track system suspendedversus vehicle

- track frame structure casted

Targets for the new development

� Increased comfort� Improved evenness of ground pressure� Capable for higher road speeds� Stable costs for drive system – same axle structure as for

wheels� Less weight for drive system

Summary and outlook

� Outlook

� Tracks will gain even more importance because of bigger machines, higher flexibility and better risk management for farmers

� Many retrofit companies� In 2011 all manufacturer of Self propelled harvesting machines had

tracks available

� CLAAS has a long history in track development and did set a standard in Ag business


LenkgetriebeCLAAS TERRA TRAC – established in AG business


Very special application – most probably a niche !
