Description

Calculated values

TL

kg

Tractor empty weight

TV

kg

Front axle load of the operational tractor without mounted implement or ballast weights

TH

kg

Rear axle load of the operational tractor without mounted implement or ballast weights

GV

kg

Total weight of front-mounted implement or front ballast

GH

kg

Permissible total weight of rear-mounted implement or rear ballast

a

m

Distance between the centre of gravity of the front-mounted implement or the front ballast and the centre of the front axle

a1

m

Distance between the centre of the front axle and the centre of the lower link connection

a2

m

Centre of gravity distance: Distance between the centre of gravity of the front-mounted implement or the front ballast and the centre of the lower link connection

b

m

Wheelbase

c

m

Distance between the centre of the rear axle and the centre of the lower link connection

d

m

Centre of gravity distance: Distance between the centre of the lower link coupling point and centre of gravity of the rear-mounted implement or rear ballast.

  1. Calculate the minimum front ballasting.
  2. Calculate the actual front axle load.
  3. Calculate the actual total weight of the tractor-implement combination.
  4. Calculate the actual rear axle load.
  5. Determine the tyre load capacity for two tractor tyres in the manufacturer specifications.
  6. Write down the determined values in the following table.
IMPORTANT
Danger of accident due to implement damage caused by excessive loads
Make sure that the calculated loads are smaller or equal to the permissible loads.
