The John Deere 4400 is a widely found compact utility tractor valued for durability and attachment flexibility. Typical features include a three-point hitch, rear PTO, four-wheel drive, power steering and ROPS. Many units use hydrostatic transmissions and are commonly paired with front loaders; exact loader models and production details should be verified using the tractor serial number and OEM parts resources.

Overview

The John Deere 4400 is commonly listed on the used market as a practical, versatile compact utility tractor. Owners and restorers prize these machines for straightforward controls, wide attachment compatibility, and long service life. You'll find many examples restored or kept in active use on small farms, acreage and commercial properties.

Common features

Most 4400s are fitted with a three-point hitch and a rear PTO, which makes them compatible with mowers, tillers, and other common implements. They typically include four-wheel drive, power steering and a Rollover Protective Structure (ROPS), all of which improve safety and handling in rough terrain.

Several sources describe the 4400 with a hydrostatic transmission and simplified loader controls (one lever to lift/lower while tilt can be controlled separately). The tractor's rear differential lock is sometimes marketed as a Posi-Lock style system to improve traction on slippery ground.

Loader and attachments

Front-end loaders are a frequent pairing for the 4400. Older listings and parts catalogs refer to loader models compatible with the chassis; examples often cited include models numbered in the 400 range, but exact loader model compatibility depends on the tractor's year and sub-model and should be confirmed against serial numbers.1

Beyond loaders, the 4400 supports a broad range of aftermarket and OEM implements: backhoes, snow blowers, blades, box scrapers and landscape rakes. That attachment flexibility helps explain why many owners keep these tractors in service for decades.

Market and parts

The 4400 shows up regularly on used-equipment sites, local classifieds and auction platforms. Good examples and restored units can command higher prices, especially when owners include working loader assemblies and well-documented maintenance history. Parts availability is generally reasonable: common items (filters, seals, bearings, hydraulics) remain obtainable from dealer networks and specialty suppliers, though some model-specific parts may be scarce for certain production years.2

Notes and verification

Older descriptions sometimes conflate different John Deere lines or reuse model numbers (for example, references to a "4400 combine" appear in some discussions). If you need shop-specs, exact production years, loader model numbers or OEM parts cross-references for a specific tractor, check the tractor's serial number and consult an official John Deere parts catalog or a trusted parts dealer before purchasing or restoring.3

Bottom line

The John Deere 4400 is valued for its durability, simple controls and wide attachment support. When evaluating a used unit, verify the exact submodel, transmission type and loader compatibility against serial-number documentation to ensure you get the correct parts and implements.
  1. Confirm production years and common production run dates for the John Deere 4400
  2. Verify whether the 4400 used a 3-speed hydrostatic transmission or another HST configuration
  3. Confirm documented compatible loader model numbers (examples cited in 400 range) for the 4400
  4. Check references that mention a "4400 combine" to determine if that model number was used on any combine or if this is a conflation of model numbers

FAQs about John Deere 4400

What are the core features of the John Deere 4400?
Common features reported for the 4400 include a three-point hitch, rear PTO, four-wheel drive, power steering, ROPS and (in many examples) a hydrostatic transmission and simple loader controls. Verify specifics by serial number before buying.
Are loaders available for the 4400?
Yes - the 4400 is commonly paired with front-end loaders. Historical listings cite loaders in the 400-series range, but exact compatible models depend on the tractor's year and submodel, so confirm compatibility with serial-number data.
Is it easy to find replacement parts?
Routine maintenance parts (filters, belts, seals, hydraulic components) are generally available through John Deere dealers and aftermarket suppliers. Some model-specific components may be harder to source for certain production runs; check parts catalogs with your tractor's serial number.
Was the 4400 ever produced as a combine?
Some older or informal references mention a "4400 combine," but model-number reuse and naming differences can cause confusion. For accurate equipment classification, consult official John Deere documentation or a dealer for the particular serial number in question.
How should I evaluate a used 4400 before purchase?
Inspect the loader and hydraulics, test the transmission and PTO, check for leaks and frame damage, review maintenance records, and confirm the serial number against parts and service references. That verification helps ensure the right parts and implement compatibility.
