1. Basis of the report
a. With regard to the language, the international search was carried out on the basis of:
the international application in the language in which it was filed.
a translation of the international application into                                          which is the language of a translation furnished for the purposes of international search (Rules 12.3(a) and 23.1(b)).
b.
This international search report has been established taking into account the rectification of an obvious mistake authorized by or notified to this Authority under Rule 91 (Rule 43.6bis(a)).
c.
With regard to any nucleotide and/or amino acid sequence disclosed in the international application, the international search was carried out on the basis of a sequence listing:
2. Certain claims were found unsearchable
3. Unity of invention is lacking
This International Searching Authority found multiple inventions in this international application, as follows:
1. claims: 1-8, 14
lawn mower comprising two discharge tunnels
2. claims: 9-13, 15-21
lawn mower comprising a specific power transfer assembly
1.
As all required additional search fees were timely paid by the applicant, this international search report covers all searchable claims.
2.
As all searchable claims could be searched without effort justifying additional fees, this Authority did not invite payment of additional fees.
3.
As only some of the required additional search fees were timely paid by the applicant, this international search report covers only those claims for which fees were paid, specifically claims Nos.:
4.
No required additional search fees were timely paid by the applicant. Consequently, this international search report is restricted to the invention first mentioned in the claims; it is covered by claims Nos.: 1-8, 14
Remark on Protest
The additional search fees were accompanied by the applicant’s protest and, where applicable, the payment of a protest fee.
The additional search fees were accompanied by the applicant’s protest but the applicable protest fee was not paid within the time limit specified in the invitation.
No protest accompanied the payment of additional search fees.
4. Title of the invention
The text is approved as submitted by the applicant.
The text has been established by this Authority to read as follows:
5. Abstract
The text is approved as submitted by the applicant.
The text has been established, according to Rule 38.2, by this Authority as it appears in Box No. IV. The applicant may, within one month from the date of mailing of this international search report, submit comments to this Authority.

A lawn mower (100) may include a blade housing (200), a power source (110) supported at least in part by the blade housing (200) to selectively rotate a drive shaft (281), a mobility assembly (120) including a first set of wheels (240) and second set of wheels (242) operably coupled to the blade housing (200), a first cutting blade (210), a second cutting blade (212), and a power transfer assembly (140). The first cutting blade (210) and the second cutting blade (212) may be disposed to be rotatable within the blade housing (200) in a same plane such that respective blade orbits of the first cutting blade (210) and the second cutting blade (212) at least partially overlap at an overlap region. The power transfer assembly (140) may be operably coupled to the drive shaft (281) and configured to drive the first cutting blade (210) and the second cutting blade (212) to rotate within the blade housing (200) in opposite directions and control timing of passage of the first cutting blade (210) and the second cutting blade (212) through the overlap region. The blade housing (200) may be configured to be operably coupled to a bagging attachment (250) via a first discharge tunnel (260) disposed proximate to the first cutting blade (210) and a second discharge tunnel (262) disposed proximate to the second cutting blade (212). The first cutting blade (210) rotates to generate a first flow path along a first side of the blade housing (200) toward the first discharge tunnel (260) and the second cutting blade (212) rotates to generate a second flow path along a second side of the blade housing (200) toward the second discharge tunnel (262).
