Electrify Cattle Chute Hydraulics

I need to retire the small gas engine that currently drives the hydraulic pump on my cattle chute and replace it with a clean, battery-powered DC solution. The chute is used daily on a working ranch, so the new setup has to match—or ideally beat—the existing system in torque while running quieter and with minimal maintenance.

Core goals
• Convert the existing hydraulic power unit from combustion to DC electric.
• Prioritize energy efficiency so the batteries last through a full working day.
• Engineer for durability and reliability; the chute lives outdoors and sees dust, mud, and winter starts.

What I’m looking for
1. A detailed conversion plan: component sizing, DC motor and pump selection, battery chemistry/capacity, controller, and any pressure-related adjustments.
2. Wiring and hydraulic schematics that drop straight into the current hose layout.
3. A parts list that I can source in North America, plus any custom fabrication notes.
4. Brief commissioning guide—startup procedure, safety checks, and recommended maintenance intervals.

Nice to have, if it fits: advice on solar trickle-charging or rapid-swap battery trays.

I’ll provide dimensions of the existing pump, flow and pressure data, and photos once we start. If you have prior projects converting agricultural or industrial hydraulics to electric, especially with cattle chutes, let me know—case studies and performance numbers will be a big plus.
We have tested our chute under DC power and have the data to provide (GPM-KWH etc) . Design will include programming /talking to smart batteries . Integration of the entire operating system.
