Breaking hard ground with motors

Click For Summary

Discussion Overview

The discussion revolves around finding an appropriate motor for breaking hard ground, particularly in the context of agricultural applications. Participants explore various motor specifications, battery requirements, and the mechanics of tillage, while also considering the practicalities of farming techniques and equipment.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning
  • Experimental/applied

Main Points Raised

  • One participant suggests that a motor's effectiveness in breaking hard ground depends on the implement it spins, such as a roto-tiller or motorized plow, and emphasizes the need to define the specific tool for the task.
  • Another participant questions the assumption of using a 50V motor and suggests exploring car batteries, noting that a typical car battery has a reserve capacity that could be relevant.
  • Concerns are raised about the feasibility of operating at 5 MPH, with some participants arguing that tillage is energy-intensive and that the speed may not be appropriate for effective soil breaking.
  • A participant points out that the concept of horsepower is often misunderstood, noting that a horse can exert more than one horsepower under certain conditions.
  • There is a discussion about the necessary battery specifications, with one participant clarifying that 160 amp-hours is needed to sustain a 20 amp draw for 8 hours.
  • Some participants express skepticism about the original poster's understanding of farming practices and suggest looking for existing methods or advice from experienced farmers.
  • One participant proposes a solar-powered solution for utilizing crop remnants, indicating a potential alternative approach to traditional tillage methods.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best motor specifications or the appropriate speed for tillage. There are multiple competing views regarding the necessary power, battery requirements, and the effectiveness of different farming implements.

Contextual Notes

Participants express uncertainty regarding the assumptions made about motor specifications, battery capacities, and the mechanics of tillage. There are also unresolved discussions about the appropriate speed and depth for effective soil breaking.

Are you contending that the use of the contraction "aren't" is proper while the full form "are not" is not?

Shirly you can't be serious.

You have not established that issues with agriculture in LDCs is due primarily to production.
You have not established that the issues with food production are limited by planting rate.
You have not established that planting rate in LDCs could be improved with robotics.
You have not established that even if planting rate in LDCs could be improved with robotics, that farmers in LDCs could buy them. If these are intended as charity, that robots are superior to equivalent cash donations.
You have not established that even if all the above were true that there exists battery technology to power this up.

But you're worried about the outer covering of these robots.
Do you understand why this does not look like you are being serious?
