Installing PTO Hydraulic Pump vs Tapping Into Rear Lift Pump
— Which Hydraulic Power Solution Fits Your Tractor?

Farmers and tractor repair shops often face a critical choice when adding auxiliary hydraulic power for log splitters, dump trailers, post hole diggers and heavy farm implements: install an independent PTO hydraulic pump, or tap into the tractor’s original rear lift pump circuit directly. Green Hydraulic, a professional agricultural hydraulic pump manufacturer, breaks down the pros, cons, performance differences and suitable scenarios of the two solutions to help you make a cost-effective, long-lasting decision.

1. Core Definition of Two Hydraulic Power Solutions

Option 1: Install a Separate PTO Hydraulic Pump

Option 2: Tap Into the Tractor Rear Lift Pump

2. Head-to-Head Comparison: PTO Pump vs Tapping Rear Lift Pump

Performance & Working Efficiency

• PTO Hydraulic Pump (Advantage)

  Independent large-displacement design delivers high GPM flow and stable pressure up to 2500–3000 PSI. Hydraulic cylinders extend and retract quickly even under heavy loads, ideal for high-demand tools like 30–40 ton log splitters and large dump trailers. No power loss to the tractor’s lifting system, so your three-point hitch maintains full lifting capacity while running attachments.

• Tapping Rear Lift Pump (Disadvantage)

  Factory rear lift pumps are low-flow (usually 4–8 GPM, 1600–1800 PSI only). Auxiliary equipment moves extremely slowly. When you operate attachments, the tractor’s rear hitch lifting speed drops drastically, and long-hour heavy use causes system overheating and pressure sag.

Impact on Tractor Original Hydraulic System

• PTO Hydraulic Pump: Zero Damage to Factory Hydraulics

  Fully independent oil circuit, no extra load on the tractor’s original pump, seals and transmission. It avoids premature wear, oil leakage and expensive tractor transmission repairs caused by overloading the factory lift pump.

• Tapping Rear Lift Pump: Accelerated Original Pump Wear

  The factory lift pump bears double load from both the rear hitch and auxiliary tools. Continuous heavy use shortens pump service life, leads to frequent seal failure and oil contamination, and you must replace the tractor’s internal pump at high labor cost once it breaks down.

Installation & Cost

• PTO Hydraulic Pump: Higher One-Time Cost, Low Long-Term Expense

  You need to purchase a complete PTO pump kit, tank and pipeline accessories. But the system runs independently, no extra maintenance fees for tractor hydraulic parts, and the pump itself has a 5–8 year service life under normal farm use. Green Hydraulic offers factory-direct wholesale kits to cut your upfront procurement cost.

• Tapping Rear Lift Pump: Low Initial Cost, Hidden Long-Term Costs

  Only split tees and extra hoses are needed at first. However, frequent oil changes, seal replacements and eventual tractor pump overhaul bring continuous hidden expenses over years of farming.

Application Scenarios

Choose PTO Hydraulic Pump If You Have:

• Heavy-duty attachments: log splitters, large dump trailers, heavy post hole augers, front loaders

• Daily long-hour hydraulic operation during planting and harvesting seasons

• Multiple hydraulic tools to run at the same time

• Large tractors above 50 HP that need to keep full rear lifting power while working

Choose Tapping Rear Lift Pump Only If You Have:

• Light-duty, occasional use: small sprayers, mini grain drills, light rake attachments

• Low horsepower compact tractors with rare auxiliary hydraulic demands

• Budget-limited small-scale hobby farms with minimal hydraulic workload
