Round 1
Reviewer 1 Report
The author's work presented is quite good and well written. The authors present an elastic tooth type lateral straw clearing roller to reduce soil disturbance, power consumption, and vibration. Also, the field experiments were carried out by the orthogonal test method.

Reviewer 2 Report
The authors of the paper "Design and Test of Elastic Tooth Type Lateral Straw Clearing Roller based on the Straw Clearing and Mulching No-tillage Precision Planter" present a relevant topic, namely the presentation of "indices for evaluating straw cleaning performance and energy consumption”, A relevant aspect for cereal farms, which makes the work have the effect of multiplying at the level of farms that want to optimize energy consumption.
The bibliographic sources, citations, key concepts used in the study are appropriately mentioned and presented by the authors of the research. Specifically, such as the work of Chen Haitao et al. [10] which shows that "the test for optimizing the combination of parameters on the influence of the number of rigid teeth, the arrangement and the rotational speed on the equivalent energy consumption and the vibration intensity".
The research methodology is substantiated, with tools and methods that confirm as clearly as possible the research results. The authors of the research used the Orthogonal Test Method, the analysis of the strength of the elastic tooth and the arrangement of the elastic teeth. Moreover, the authors base their research on the relevant test schemes for the research results.
The research results are presented by the research authors based on the models mentioned in the research methodology, among which we mention the results generated by factors that "had extremely significant effects on the indices of evaluation of straw cleaning performance and energy consumption." Moreover, the authors also highlighted the factors that did not significantly influence the research result. However, we ask the authors of the research to highlight the main scientific results as a personal contribution to the scientific literature, given that the results are adequately presented but much focused on the application side and can create a multiplier effect for work done on farms globally.
The conclusions are presented by the authors of the research, respectively the authors emphasize for example the fact that "lateral cleaning of straws of elastic tooth type reduced energy consumption by 63.3% and vibration intensity by 43.2%". However, we suggest that the study authors also present the limitations of the study as well as future research. Moreover, as we mentioned in the results chapter, we appreciate that the personal scientific results that contribute to the scientific literature should be highlighted.
We congratulate the research team, we suggest the revision of the paper according to the above mentioned.

Reviewer 3 Report
The authors presented the design of an elastic tooth type lateral straw clearing roller to no-tillage precision planter for straw removal and mulching, which were previously equipped with rigid teeth. The key parameters and values affecting the performance of the device were determined based on theoretical analysis. The comparative test of both devices showed that there was reduced power consumption for the elastic tooth type lateral straw cleaning roller over 60% and vibration intensity over 40% at no crucial difference in the straw clearing rate between the two.
The paper is interesting and fitted to the journal topic. I have no fundamental objections to its content.
Strong
Very well-done illustrations. The graphics are very professional and therefore easy to read. From this point of view, the article reads with pleasure. A small comment, more to future papers. An even better effect in drawing clarity can be achieved by using a font similar to technical writing, even Arial, in place of Times New Roman. But using the current font is certainly not a mistake.
Weak
In the present state, the title of the subsection "3.4. Parameter combination optimization" is not justified in the content. It could, at best, be this: “3.4. Improvements in parameter combination ...”
In the article I did not find any detailed description of the optimization method. Even when we use statistical software, we should present the details of the method that is implemented in this system.
I can see two ways to improve this problem:
1. Remove the connotations of optimization from the paper and improve instead.
or
2. (Select) and describe the optimization procedure in detail- better.
I can recommend a simple but effective method of optimizing (and modeling) - RSM, based on an orthogonal array:

Introduction
We avoid "wholesale" quoting of literature as in the first sentence of this chapter: [1-6]. It would be appropriate to add at least some details of each of these references and eventually get specified authors.
2. Materials and Methods
Figure 3 can be boldly enlarged for improved readability.
Subchapter 2.2.3. Test scheme
What is L27(313)? Maybe L27 (33) is proper?
Subchapter 3. Vibration intensity.
What is oeration?
Small errors, I hope typographic only:
Is: Hou shouyin et al. [11,12]; should be: Hou Shouyin et al. [11,12]
Below subchapter 2.1.4 title. One “the” will be enough
