In some embodiments, the housing system 20 of the deck-mounted mower 100 further includes a storage article 24 at least partially movably connected with the front cover 23. The storage piece 24 is formed with at least one storage space 241 with an opening substantially upward, and the storage space 241 is located rearward of the energy storage device 96 in the front-rear direction. It should be noted that the storage space 241 is not the same space as the accommodating cavity formed by the front cover for accommodating the energy storage device. The storage boxes of the related mower are fixedly mounted on the vehicle body, so that the use flexibility of a user is greatly reduced, and the cleaning of the inner space is not facilitated. The movable connection between the storage article 24 and the front cover 23 is arranged in the application, so that the user can take out the articles in the storage space more conveniently. For example, when a user stores fertilizer or crops using the storage space 241, the fertilizer or crops can be more conveniently taken out by adjusting the angle of the storage piece 24 or directly taking out the storage piece 24. When the storage article is in the storage state, the storage article can form a receiving cavity with the front cover, and the receiving cavity is used for receiving the energy storage device. Of course, it is also possible to provide the energy storage device with a receiving space in the front cover independently.

In some embodiments, referring to fig. 4, the storage item 24 is a flip-top storage box, one end of which is rotatably mounted to the front cover 23. The storage piece 24 can be flipped over relative to the front cover 23 to change the opening direction of the storage space 241. Specifically, the storage piece 24 also includes a rotation axis. Wherein the rotation shaft is connected to the front cover 23, and the storage piece 24 is rotatable about an axis 242 of the rotation shaft to be turned over within a predetermined angular range. The storage member 24 is flipped about the axis 242 by an angle of 180 degrees or less. Of course, the rotation axis may also be linked to the storage piece 24, and the above-mentioned angle should be understood as the angle at which the storage piece 24 is turned over relative to the front cover 23.

In other embodiments, as shown with reference to fig. 5-7, the front cover 23 forms a receiving cavity 231 for receiving at least the energy storage device 96. At least a portion of the storage member 24a is disposed behind the energy storage device 96. Unlike the embodiments described above, the storage item 24a is a retractable storage box, at least a portion of the storage item 24a being movable relative to the front cover 23. Specifically, the storage article 24a includes a first storage article 241a and a second storage article 242a. Wherein the first storage article 241a is separable relative to the front cover 23. The second storage piece 242a is provided in fixed connection or in reversible connection with the front cover 23. The first storage piece 241a has a handle 243a for convenient operation by a user. The user can conveniently lift the handle 243a to freely take or place the first storage object 241a. Of course, the handle 243a may be foldable, which saves space. In some embodiments, the handle 243a is not a true handle, and any location on the first storage article 241a that a user can grasp may be considered a handle. Accordingly, the form and position of the grip 243a is not limited in this application. The first storage object 241a forms a first storage space 244a, and the second storage object 242a forms a second storage space 245a. Wherein, the opening direction of the first storage space 244a is different from the opening direction of the second storage space 245a. The volume of the first storage space 244a is different from the volume of the second storage space 245a. After the user pulls out the first storage object 241a, the user can take or store the object from the second storage space 245a. Thus, the user can store different articles separately, and the user experience is improved.

The front cover 23 includes an upper cover, which has an open position and a closed position 232. When the upper cover 232 is in the open position, the user may access the storage space 241 or perform an operation of flipping or taking the stored items 24. The storage space 241 can be used for storing small tools, gloves, sun-shading caps, clothes and the like according to the requirements of users, so that convenience is brought to the users and the comfort level of mowing work is improved. Specifically, the upper cover of the front cover 23 may be movably and rotatably connected to the front cover 23 by a rail, a hinge, or the like, which will not be described in detail herein. The upper cover of the front cover 23 may be opened according to the configuration of the storage space, and the specific shape and size of the upper cover are not limited in the present application.

In some embodiments, referring to fig. 8, the maximum length L1 of the storage space 241 formed by the storage object 24 in the front-rear direction is 150mm or more and 300mm or less.

It should be noted that, when only one storage space 241 is formed by the storage objects 24, the maximum length L1 of the storage space 241 in the front-rear direction is defined as the size of the storage space 241. When the storage space 241 formed by the storage objects 24 has a plurality of storage spaces, the maximum length L1 of the storage space 241 in the front-rear direction is considered as the sum of all the storage spaces.

In some embodiments, the storage space 241 is separated from the energy storage device 96 by a sidewall of the storage object 24. In this way, the items within the storage compartment 24 do not contaminate the energy storage device 96, while the natural barrier is formed by the structure of the storage compartment 24 itself separating the two, making the space more compact and expanding the capacity of the storage space 241. In the present application, the material of the storage member 24 is not limited. Can be plastic, metal, a mixture of plastic and metal or other materials.

Currently available riding mowers, garden tractors, and the like allow use of mounted tools, whether in front of or behind the lawn maintenance vehicle. When using such tools, many known fastening methods include the use of threaded fasteners or the need for a separate hand tool for attachment. This may require additional time and effort to connect the tool to the lawn maintenance vehicle. The tools described above primarily include, but are not limited to: spade, hammer, screwdriver, ratchet kit, wrench, etc.

Referring to fig. 1, the deck mower 100 further comprises a tool attachment means 97. The tool attachment device 97 in this application may be described as a "quick attachment device" in that it does not require the use of a mating tool such as a fastener or the like to effect attachment of the tool. Examples of the manned mower 100 include, but are not limited to, a standing mower, a lawn tractor, or other utility vehicle, such as an all-terrain vehicle. Further, a trailer coupler 97a connected to the frame 91 is provided near the tool attachment 97 of the deck mower 100. When the manned mower 100 fails or runs short and cannot travel normally, the user can pull the manned mower that cannot travel normally back to the charging station or the after-market maintenance part by connecting the manned mower to the trailer 97a via another device. Of course, the trailer coupler 97a described above may also have other means for transporting, for example, the deck mower 100 through the trailer coupler 97a.

Referring to fig. 9, a tool attachment device 97 is mounted to the frame 91 and is disposed rearward of the seat 92. Of course, the tool attachment 97 could be mounted at other locations on the deck 100, such as the front, left or right. It should be noted that the above-mentioned seat may also be understood as a support member, and in other models, such as a standing mower, the support member is a standing portion for supporting an operator. In some embodiments, tool attachment device 97 includes at least one attachment 971, at least one attachment 971 allowing for insertion of tool 973 in a generally up-down direction. In some embodiments, the attachment member 971 comprises a tubular member including a receiving cavity 971a configured to receive at least a portion of the tool 973, the receiving cavity 971a extending generally in an up-down direction. The attachment 971 includes a hollow tubular member, and the tool 973 is capable of adapting to the hollow region of the tubular member to be retained within the tubular member. In some embodiments, the tool attachment device 97 includes at least two attachment members 971, each attachment member 971 being capable of independently adapting a tool. In some embodiments, the number of accessory members 971 may also be 3, 4, or even more. The attachment 971 may be shaped as a round tube or a square tube. In some embodiments, the attachment 971 is made of a metallic material, thereby ensuring that no deformation occurs when the tool is placed. In some embodiments, the tool 973 comprises a pole-type tool, such as a shovel, hammer, or the like.

Tool attachment device 97 further includes a connector 972 fixedly mounted to frame 91 or integrally formed with frame 91. In some embodiments, the connector 972 includes a stopper 9721 fixedly coupled with the frame 91 and a fixing 9722 extending in the left-right direction. The attachment 971 is mounted to the mount 9722. In some embodiments, the securing member 9722 is removably mounted to the 9721 retainer member, such that a user can flexibly choose to remove the securing member and the attached member when not needed to carry a tool. Of course, the user may also adapt the appropriate accessory 971 according to the choice of tool 973 to be carried. Of course, the connector may take other forms, as shown in fig. 10, and the connector 972a includes an L-shaped rectangular tube 9721a. Rectangular tube 9721a is fixed to frame 91, and attachment 971 is fixed to rectangular tube 9721a. In some embodiments, the connector 972a further includes a bottom plate 9722a disposed at the bottom of the attachment 971 for supporting the attachment 972 a.

The tool attachment device 97 of the present application can provide a convenient, quick and inexpensive way to connect a tool to a manned mower without the use of a separate hand tool, such as a screwdriver, ratchet kit, wrench, or the like. The described structure may also provide a relatively strong connection between the tool and the lawn maintenance vehicle, as compared to other attachment methods and structures.
