Engineered for hydrostatic drive systems, the PG-1GNP-DY1X-XXXX is designed to help restore smooth response, reliable hydraulic performance, and consistent drive power on compatible equipment. This replacement pump is commonly referenced as a replacement for Hydro-Gear BDP-10A-414, as well as Toro and Exmark part number 103-1942 and Stens 025-011.

This genuine Hydro-Gear pump fits select Exmark Lazer Z HP and Lazer Z CT models along with a wide range of Toro mower models, including units such as 74161, 74162, 74163, 74164, 74165, 74166, 74167, 74176, 74177, 74178, 74179, 74197, 74198, 74199, 74411, 74413, 74414, 74415, 74416, 74417, 74441, 74442, 74444, 74445, 74448, 74449, and 74450TE, among others. It may also fit other equipment using BDP-10A-414.

For proper ordering, always verify the Hydro-Gear part number stamped directly on your existing pump before purchasing. Hydraulic pump replacement should also include proper system maintenance. It is strongly recommended to flush tanks and lines, install a new oil filter, and inspect or replace the wheel motor when needed. Contamination left in the hydraulic system is one of the most common causes of premature hydro pump failure.
