GEHL 418, 420 Parts Catalog – Factory OEM Manual

If you’re wrenching on a GEHL 418, 420 Parts Catalog you need the factory breakdown – not some photocopy with missing callouts. I’ve seen too many guys order a part blind because the aftermarket diagram shifted a reference number. This is the original 28-page Parts Catalog from GEHL Agriculture. It covers the 418 and 420 Finger Wheel V-Rakes, and if you need to find a bolt, a hub, or a hydraulic fitting, you stop guessing and start flipping. The torque values for standard hardware are printed on the inside back cover – right where you can smear grease on them without losing the number.

Main Frame & Drawbar Assembly Breakdown

Pages 4 through 9 give you the exploded view of the main frame and drawbar. Every cap screw, lock nut, and flange washer has a reference number tied to the parts list. The manual uses a hexagon symbol with a number inside for torque values in foot-pounds – that’s not a suggestion, that’s the spec. I’ve had a customer snap a Grade 5 bolt because he used a torque wrench set for Grade 8. This catalog prevents that kind of weekend-ruining mistake. You also get the full fastener description abbreviations: “CS” for cap screw, “FLN” for flanged lock nut, and so on. The hardware listed is for mounting information only – it tells you what size and grade, but you still have to buy those parts separately. That’s exactly what a real parts manual does: it gives you the part number so you can order it right the first time.

Does This Parts Catalog Cover Torque Specs?

Yes – but only for standard attaching hardware. The inside back cover lists the factory torque values for Grade 5 cap screws and bolts, plus the corresponding hex nut grade. If you’re torquing a flange bolt on the hitchjack (page 15), you use the spec for the fastener size shown in the drawing. The manual also includes a note: all cap screws and bolts are Grade 5, cadmium or zinc plated, unless otherwise specified. That means you don’t mix hardware grades on a rake that gets towed at road speeds. I’ve seen what happens when a Grade 2 bolt lets go on a farm tractor. It’s ugly.

28 Pages of Factory Part Numbers

The catalog runs 28 pages from the inside front cover to the numerical index. Every section – from Decal Locations (pages 2-3) to Options & Accessories (pages 16-18) – gives you the exact GEHL part number for each component. No “generic cross-reference” that may or may not fit. The numerical index on pages 20-21 lets you look up a part number and find which page and reference number it belongs to. That saves half an hour of flipping when you already have the old part in your hand. The alphabetical index (page 19) works the same way but for descriptions like “Hitchjack” or “Center Wheel.” This manual is about finding parts, not about theory.

Check the Decal Locations First

Pages 2-3 show where every safety decal and identification plate goes. If you’re restoring a rake or need to replace a faded decal, you get the exact decal part number and its position. The manual even tells you that the model and serial number decal is on the left side width adjustment wheel pivot frame member – “left” being determined from behind the machine facing forward. That kind of detail keeps you from ordering decals for the wrong side. I’ve had dealers send the wrong decal because they guessed the location. GEHL’s factory manual doesn’t guess.

Hydraulics Section: Factory Routing and Parts

Pages 12-13 cover the hydraulic system – cylinders, hoses, fittings, and the control valves. The exploded drawing shows each component with a reference number. If you need a hose replacement, the part number calls out the correct length and fitting type. The manual includes a note about “wet” products: a teardrop symbol with a number corresponds to an oil or grease description in the parts list. That matters when you order a seal kit – the wrong viscosity can wreck a cylinder in a season. For anyone working on a GEHL 418 or 420 V-Rake, these two pages are worth the price of the whole catalog.

Audience Fit: Who Should Buy This Manual?

You need this manual if you own or maintain a GEHL 418 or 420 Finger Wheel V-Rake. It’s for the farmer who wants to order parts without calling the dealer every time, for the independent mechanic who gets handed a broken rake, and for the shop owner who needs a quick reference for part numbers and torque values. The manual doesn’t teach you how to fix the rake – it gives you the part numbers so you can get the right piece of metal the first time. That’s what a parts catalog does. If you’re a DIYer with basic mechanical sense, you can use this manual. The exploded views are clear; the abbreviations are listed on page 1. You’ll need a set of wrenches and a torque wrench, but that’s your toolbox problem, not the manual’s.

Source Validity: Why OEM Beats Aftermarket

I’ve seen aftermarket “compilations” that reuse old drawings with wrong reference numbers. This is the original GEHL publication – form number 909818, replaces 908132. It came from the factory. The part numbers are what GEHL’s own dealers use. If you try to cross-reference a GEHL part with a generic catalog, you might get a close-enough part that doesn’t fit the splines or the bolt pattern. I learned that lesson on a hydraulic motor once – wasted a day. OEM documentation eliminates that gamble. For a deeper understanding of the equipment’s engine (if you’re working on the tractor pulling the rake), check out this Wikipedia article on diesel engines. But for the rake itself, you stick with the factory manual.
