Discussion Overview
The discussion revolves around the feasibility of creating a portable grass trimmer that can simultaneously cut and vacuum grass. Participants explore various aspects of this concept, including practicality, design considerations, and comparisons to existing equipment.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant questions the necessity of a combined cutting and vacuuming device, suggesting that bagging cuttings is simpler and more cost-effective.
- Another participant proposes that mower blades function similarly to fans, implying they already assist in moving cut grass.
- A different viewpoint describes mower blades as impellers that throw cuttings against the mowing deck, leading to bagging or scattering of debris.
- There is a suggestion that on an industrial scale, it may be more efficient to allow grass to dry before vacuuming it up.
- Participants discuss the idea of a "nano-scale" version of the device for personal use, with one referencing a specific trimmer model as a potential example.
- Clarification arises regarding terminology, with one participant distinguishing between lawnmowers and weed whackers, noting the latter's suitability for tight spaces.
- Concerns are raised about the complexity and practicality of integrating cutting and vacuuming mechanisms, including issues related to power take-offs and debris management.
Areas of Agreement / Disagreement
Participants express differing opinions on the practicality and necessity of a grass trimmer that vacuums simultaneously. There is no consensus on whether such a device would be beneficial or efficient compared to traditional methods.
Contextual Notes
Participants mention various assumptions regarding the design and functionality of existing grass cutting equipment, as well as the specific needs based on geographical location.

Maybe it was a homebuilt unit on Daily Planet.. my memory fails me, but I know for sure that I saw it somewhere.
On the other hand, I can't figure out why anyone would want to do that, when simply bagging the cuttings is so much easier and cheaper and more convenient.

Doesn't the blades of the mower act as a fan already, so it in a way already is a vacum?

I'd say that they're more of an impeller. They throw the cuttings against the inner surface of the mowing deck. Where that surface is removed to form a chute, the debris goes out and gets bagged (or just strewn about the yard).

On an industrial scale, it's better to cut the grass and let it dry a bit before you hoover it up...
But you may need a nano-scale version of this to use in your back yard

Depends upon location. If he lives in Canada, that could be his back yard. (My signature refers to the time when I parked a Cessna 150 in my friend's yard.)AlephZero said:But you may need a nano-scale version of this to use in your back yard

yeah i need to make a nano size of that one..and that is my problem. like this kind http://www.husqvarna.com/us/products/trimmers/husqvarna-trimmers-for-homeowners/

Okay, that's a different scene. I thought that you meant a lawnmower, which is what we use in North America for most cutting. What you picture is a weed whacker. That's for tight areas or stuff that is too tough for a mower. Given its limited scope of use, it would be a lot easier and cheaper to just take after it with a rake. Think of all the crap involved in power take-offs and sucking and ducting and carrying bags around...
