Horse was worshipped on the advice of brahmans

[shastarSingh]

Umdat ut tawarikh is a huge persian granth written in 5 volumes (called Daftars) by Lala Sohan Lal Suri who was the official chronicler, record keeper and diplomatic representative (Vakil) of Maharaja Ranjit Singh and his successors and even British Residents after the annexation of Punjab. Suri writes:

In 1830, all the chieftains and Sardars enthusiastically engaged 
themselves in the preparation of their garments for the dussehra day.Celebrations of dussehra were begun by worshiping of horse, cannon and sword according to the 
advice of the Brahmans.The Maharaja then visited Harmandir Sahib, took sacred bath, made prostration and offered large sums of money as ardas in different bungas and other places. The poor and needy shared his bounty, as the Maharaja showered money with both hands.

Not sure why Brahmans were consulted to do worshipping of horse.

Horse has always been dear to khalsa.

Polier in 1780's writes:

Though they make merry on the demise of any of their brethren.they mourn for the death of a horse, thus showing their love of an animal so necessary to them in their professional capacity.
