About the John Deere 494A and 495A

The John Deere 494A and 495A were toolbar-mounted row crop planters produced in the 1960s and 1970s, designed for 4-row corn planting in the standard 38-inch and 40-inch row spacings that dominated Corn Belt farming in that era. The 494A was configured for hill-drop or drill corn planting, while the 495A offered the additional flexibility of hill-drop or drill planting in a single unit without requiring separate attachment changes — the key operational distinction between the two models. Both used John Deere's cell-type metering mechanism, with seed plates that had to be matched to corn seed size (flat, round, or large round) and adjusted for target plant population. The attachment lineup available for the 494A and 495A was extensive, including dry fertilizer hoppers, liquid fertilizer units, trash kickers for minimum-tillage conditions, and multi-row extensions for 6-row and 8-row configurations. The 494A and 495A were also capable of planting soybeans and maize with the appropriate seed plates and population chart settings documented in this manual.

What This Manual Covers

This 64-page manual covers both the 494A and 495A with separate instructions where procedures differ between models. Key sections include:

• Identification & Specifications — model identification views and factory specifications for both planters
• Operation — preparing the tractor and planter; hitching and transporting; marker operation; planting depth adjustment; hill-drop planting (494A); drill planting (494A); hill-drop or drill planting (495A); soybean, maize, and plant population charts
• Attachments — fertilizer and dry fertilizer hopper attachments; insecticide and herbicide attachments; trash kickers and minimum tillage attachment; press wheels, bands, scrapers, and rubber tires; row leveling blades and gauge shoes; double disk furrowers and disk coverers; six-row planting extension and eight-row hitch; beet seed hopper (494A); pea and bean attachment
• Safety, Lubrication & Service — safety guidelines; lubrication points; beginning- and end-of-season service; timing the planter; runner alignment and rockshaft bearings; common planting problems and causes

Why This Manual Matters

• 494A vs. 495A procedures documented separately: The two models handle hill-drop and drill planting differently, and the manual documents each model's specific procedures rather than combining them — essential when operating or setting up a machine you didn't buy new
• Planter timing procedure: Correctly timing the metering mechanism is the single most important setup task for consistent seed spacing — the factory timing procedure documented here is the authoritative reference for both models
• Seed plate and population charts: Corn, soybean, maize, and population chart tables are included with the correct plate selection for each seed type and size — the reference that operators reach for when switching crops or seed varieties
• Troubleshooting common planting problems: Skip patterns, doubles, uneven spacing, and population errors are documented with their causes and corrections — the diagnostic section that's most valuable during planting season when there's no time to guess
• Minimum tillage attachment documentation: Trash kickers and minimum-tillage attachments are covered for operators running reduced-tillage systems, which were becoming common as these planters aged into the conservation tillage era
• Original factory content: This is the manual John Deere issued to 494A and 495A owners, carrying manual code OM-B25384
