This agreement, effective as of July 22, 2017, is entered into as of this 6th
day of September, 2017 by and between The Davey Tree Expert Company, an Ohio
corporation (the "Company"), and Karl J. Warnke, non-executive Chairman of the
Board and retired Chief Executive Officer of the Company (''Warnke").

Warnke retired from active employment with the Company, and was succeeded as CEO

will remain in his current capacity of non-executive Chairman of the Board
during the remainder of his current term as a director, concluding with the 2018
Annual Meeting of Shareholders, currently anticipated to be held in May 2018
(the "2018 Annual Meeting). The purpose of this Agreement is to set forth the
Company's and Warnke's mutual understanding as to certain matters pertaining to
his service as non-executive Chairman of the Board.

In consideration of the mutual covenants and agreements set forth herein, the
Company and Warnke hereby agree as follows:

1.    Non-Executive Chairman, Agreed Service Period. During the Agreed Service
Period (as hereinafter defined), Warnke will continue as a member of the Board
of Directors of the Company and will continue to hold the position of

2.2     Unless Warnke advises the Company to the contrary as provided in Section
2.1, management of the Company will recommend to the Corporate Governance
Committee of the Board and to the Board that Warnke be nominated for re-election

Board held in conjunction with the 2018 Annual Meeting and continuing through
the conclusion of the 2019 Annual Meeting of Shareholders, currently anticipated

Warnke, the Agreed Service Period will thereafter continue through the
conclusion of the 2019 Annual Meeting.

non-executive Chairman as provided above in this Section 2, it is understood and
agreed that Warnke will retire as non-executive Chairman of the Board effective
