6.1:   Sample calculations: Exercise for Combine Harvester

Calculation exercise "Combine harvester":  

Part 1: Machinery costs

Part 2: Procedural costs

Part 3: Comparative costs and minimum extent of utilization at equal quality of work.

Part 4: Comparative costs and minimum extent of utilization at different quality of work.


 6.1.1:    Part 1a: Machinery costs,1a -task

 
Materials  

The average costs per ha at an average use of 600 ha per year amount to....

A.  153,45 € per hectare
B.    84,33 € per hectare
C.  109,43 € per hectare
D.   72,56 € per hectare

 

 6.1.2:    Part 1b: Machinery costs,1b -solution

 
   Materials

 

 6.1.3:    Part 2a: Procedural costs, 2a -task

 
Materials  

The entire procedural costs (machinery costs + labor costs) per hectare are on average:

A.  123,43 € per hectare
B.  130,32 € per hectare
C.  112,68 € per hectare
D. 117,83 € per hectare

 

 6.1.4:    Part 2b: Processing costs, 2b -solution

 
   Materials

 

 6.1.5:    Part 3a: Comparison costs and Minimum Extent of Usage, 3a -task

 
Materials  

The minimum extent of utilization in hectares per year for the owned harvester

A.  600 ha per year
B.  543 ha per year
C.  400 ha per year
D.  489 ha per year

 

 6.1.6:  Part 3b: Comparison of costs and minimum extent of utilization, 3b -solution

 
   Materials

 

 6.1.7:    Part 4a:
Comparative costs and minimum extent of utilization, taking into account differences in the quality of work - Exercise 1, 4a -task

 
Materials

The minimum extent of utilization in hectares per year for the owned harvester under consideration of timeliness costs is:

A.  418,8 ha per year
B.  600 ha per year
C.  350 ha per year
D.  400 ha per year

 

 6.1.8:    Part 4b: MEU with differences in the quality of work, 4b -solution 1 and task 2

 
Materials

The minimum extent of utilization in hectares per year for the owned harvesters, under consideration of higher yield losses due to internal mechanization

A.  592,5 ha per year
B.  600 ha per year
C.  489 ha per year
D.  543 ha per year

 

 6.1.9:    Part 4c: MEU with differences in the quality of work, 4c -solution

 
 Material

The correct answer is: The minimum extent of utilization for an owned harvester, taking into account the higher losses on the side of internal mechanization, is 592.5 ha per year. Accounting for both effects simultaneously, the minimum workload is only at 447.6 ha per year.
