Pre Pruning Machine Pass Speed Calculator
Budget actual pre-pruner row/pass travel and caller end-turn time per pass at matched measured travel rate; not route coordinate transformation, optimal machine speed or equipment safety.
Description
Pre-pruning time combines row travel with repeated turnaround allowances.
Pre-pruning time combines row travel with repeated turnaround allowances. A calibrated travel rate should match the planned operation.1
Enter nonempty positive lengths, integer passes 1–100, positive m/min rate and nonnegative turnaround minutes per pass. Return distance, total row-passes and time.
When to use Pre Pruning Machine Pass Speed Calculator
Use Pre Pruning Machine Pass Speed Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No route optimization, equipment setting or machine performance is guaranteed.
Prepare the measured vineyard records, aligned lists and independently verified local limits or catalog requested. Keep units, crop stages and observation periods consistent.
How to use Pre Pruning Machine Pass Speed Calculator and understand its results
- Prepare the measured vineyard records, aligned lists and independently verified local limits or catalog requested. Keep units, crop stages and observation periods consistent.
- Enter observedRowLengthsM, callerPassesPerRow, measuredPrePrunerTravelMMinute, callerTurnaroundMinutesPerPass using the field table and calculation rules, then run the tool.
- Read plannedTotalPrePrunerTravelM, plannedWholeRowPasses, modeledPrePruningSessionMinutes. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedRowLengthsM | Observed row lengths m | list of number | Required |
| callerPassesPerRow | Caller passes per row | number | Required |
| measuredPrePrunerTravelMMinute | Measured pre pruner travel m minute | number | Required |
| callerTurnaroundMinutesPerPass | Caller turnaround minutes per pass | number | Required |
Enter nonempty positive lengths, integer passes 1–100, positive m/min rate and nonnegative turnaround minutes per pass. Return distance, total row-passes and time.
distance=sum(rowLengths)×passes; minutes=distance/rate+rowCount×passes×turnTime Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| plannedTotalPrePrunerTravelM | Planned total pre pruner travel m | number |
| plannedWholeRowPasses | Planned whole row passes | number |
| modeledPrePruningSessionMinutes | Modeled pre pruning session minutes | number |

}Limitations and assumptions
No route optimization, equipment setting or machine performance is guaranteed.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Harvester Throughput Hectares Hour Calculator: Harvester throughput depends on whether hours include downtime. Unequal sessions should be pooled by area and exposure. For a complementary task, use Brush Removal Rate After Pre Pruning Calculator: Brush-removal productivity should use net collected mass and active hours. Tare and unequal observation time change the pooled rate.
