The phenomenon you observed as far more to do with the tiny plot sizes in most of rural India than it had to do with the cost of labor.
Many/most farmers have farms sized such that they are, if not as bad as mere subsistence, unable to justify the efficiency gains of mechanization. This is not true in other parts of India, like the western states of Punjab and Haryana, where farms are larger and just about every farmer has a tractor. There are some cooperatives where multiple smallholders coordinate to share larger machines like combine harvesters which none but the very largest farmers can justify purchasing for personal use.
Optimal economic policy (in terms of total yield and efficiency) is heavily in favor of consolidating plots to allow economies of scale. This is politically untenable in much of India, hence your observation. However, it isn’t a universal state of affairs, and many other fruits of industrialization are better adopted.
