分数是本图鉴内的相对0–100分。用于浏览，不是工程规格。
简短问答
这类交通工具要看哪些本地机构或走廊规则？
先看本地视角中的型式认定、营运许可与枢纽——不要假定一份全球清单。
Is this a buying guide?
No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.
Are the scores official?
No. The six scores are relative editorial 0–100 marks across the 48 types on this site.
Where do the photos come from?
Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.
Why metric units?
Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.
How is this different from a wiki article?
Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.
拖拉机的推进、结构、控制与安全在同一运行包线内耦合。先分清各系统名称与职责，便于故障模式与合规审查。
下方仪表为设计裕度、可维护性与人因的相对评分，用于同级平台比较。
系统
车身·载荷路径
就拖拉机而言，Steel frame carries 发动机 mass; Category I–IV hitch links implement lift arms and top link to mounted tools.
推进·动力
就拖拉机而言，Flywheel PTO spins at rated RPM to drive mowers, balers, and pumps through guarded universal joints.
制动·能量回收
就拖拉机而言，Hydrostatic pedals give infinite speed control; powershift transmissions shuttle ranges for field work.
