Predictika · Fertilizer spreader quotes

An AI sales agent's fertilizer spreader quote, checked before it goes out

An AI sales agent prepares a quote for a KUHN AXIS 2-series fertilizer spreader: the model, the hopper extension, the control, the section control, border spreading, the working width and capacity the farm needs, and what the tractor supplies. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of how those choices fit together and returns a verdict, every reason and the hopper capacity it computed.

Scope: One KUHN AXIS 2-series spreader per quote: model, hopper extension, control, VariSpread, OptiPoint, border spreading, hitch, tractor oil flow, working width and capacity. See everything this validator covers

This validator models KUHN AXIS 2-series spreader quotes, not just the scenarios shown below.

  • Models — the AXIS 20.2 W, 30.2 W, 40.2 W, 40.2 M-EMC-W, 40.2 H-EMC-W, 50.2 M-EMC-W and 50.2 H-EMC-W.
  • Hopper extensions — the L and XL extensions, each listed for some models only, with the hopper capacity computed from the model and the extension.
  • Control — QUANTRON-A or an ISOBUS terminal as listed for each model, with a terminal other than a KUHN CCI terminal going to a person, and OptiPoint needing a compatible ISOBUS terminal.
  • VariSpread and border spreading — VS 2, VS 8 and VS PRO section control, and TELIMAT, GSE 30 and GSE 60 border spreading, with TELIMAT for PTO-driven models only.
  • Tractor — the hydraulic oil flow the H-EMC disc drive needs and the hitch category.
  • Width and capacity — the working width and capacity the farm requires against the model, with widths of 37 m and more going to a person, and the capacity the quote states against the computed one.

Any KUHN AXIS 2-series quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: other KUHN spreader series and other KUHN machines. The validator models no prices.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Hopper extensions that exist for some models onlyOnly with care
Each extension is listed for some models and not others, so every extension needs a rule that reads the model, and the list grows with every extension added.		The model and the extension are fields of one request and are checked against each other on every call.
A control that is listed per modelOnly with care
Each model is listed with one control only, and OptiPoint needs another, so every pairing is its own rule.		The model, the control and OptiPoint are in the same request and are checked together on every call.
Capacity the farm needs against the hopperOnly with workarounds
The hopper capacity depends on the model and the extension, so it has to be calculated before it can be compared with the need and with the capacity the quote states.		The model, the extension, the need and the stated capacity are compared in the same pass.
Tractor oil flow and border spreading that depend on the driveOnly with care
TELIMAT is for PTO-driven models and the hydraulic disc drive needs a minimum oil flow, so each is a rule that reads the model.		The model, the border option and the oil flow are checked together on every call.
A working width with an approval rangeOnly with care
The standard discs cover 24 to 36 m and wider work needs a person, so a block and an approval range have to be kept in step.		Both ranges are checked in the same pass, and blocks and approvals come back together.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1The quote states a hopper capacity of 2,300 liters, but the AXIS 20.2 W with the L 800 extension holds 1,800 liters.
2No hopper extension is listed for the AXIS 50.2 H-EMC-W; its hopper is fixed at 4,200 liters.
3The L 1,500 hopper extension is not compatible with the AXIS 20.2; the compatible extensions are L 603, L 800, XL 1,103 and XL 1,300.
4The required capacity of 3,300 liters is above the 3,200 liters of the AXIS 40.2 W with the XL 1,800 extension.
5The required working width of 37 m is above the 36 m the AXIS 20.2 W is listed for.
6The required working width of 11 m is below the 12 m minimum working width listed for the AXIS range.
7A working width of 40 m on the AXIS 40.2 M-EMC-W is above the 24 to 36 m range of the standard spreading discs; confirm the disc type with a KUHN dealer.
8The AXIS 40.2 W is listed with the QUANTRON-A control box only, not with an ISOBUS terminal.
9The AXIS 50.2 M-EMC-W is listed with an ISOBUS terminal only, not with the QUANTRON-A control box.
10A terminal other than a KUHN CCI terminal is selected; confirm ISOBUS compatibility with the AXIS 40.2 H-EMC-W with a KUHN dealer.
11VS 2 section control is listed for the AXIS W models; the AXIS 40.2 M-EMC-W has EMC and takes VS 8 or VS PRO.
12VS PRO section control is listed for the EMC models only, not for the AXIS 30.2 W.
13OptiPoint headland control needs a compatible ISOBUS terminal; the control selected is QUANTRON-A.
14OptiPoint works with VariSpread section control; no section control is selected on the AXIS 50.2 H-EMC-W.
15TELIMAT border spreading is listed for PTO-driven models only; the AXIS 40.2 H-EMC-W has hydraulic disc drive.
16Axmat is listed as an option for the AXIS 50.2 only, not for the AXIS 40.2 H-EMC-W.
17The tractor supplies 44 l/min, below the 45 l/min the AXIS 40.2 H-EMC-W hydraulic disc drive needs.
18The AXIS 40.2 W is listed with a category 2 hitch, not the selected category.
19The AXIS 50.2 H-EMC-W is listed with a category 3 hitch (3/4N quick hitch optional), not the selected category.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for a KUHN AXIS 2-series fertilizer spreader: the model, the hopper extension, the control, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of how those choices fit together and returns a verdict, every reason and the hopper capacity it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a KUHN AXIS 40.2 W fertilizer spreader with the XL 1300 hopper extension, controlled with the QUANTRON-A control box. The farm needs a working width of 24 m and a hopper capacity of 3,000 liters. The rest of the request is on screen. The quote states a hopper capacity of 3,200 liters.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The required capacity of 3,000 liters is above the 2,700 liters of the AXIS 40.2 W with the XL 1,300 extension. The quote states a hopper capacity of 3,200 liters, but the AXIS 40.2 W with the XL 1,300 extension holds 2,700 liters. OptiPoint headland control needs a compatible ISOBUS terminal; the control selected is QUANTRON-A.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for capacity the farm needs against the hopper, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to AXIS 40.2 M-EMC-W, the hopper extension to XL 1800, the control to KUHN ISOBUS terminal and the section control to VariSpread VS PRO.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
