Branson 6640C 2012 Operators Manual

I’ve seen more than a few tractors come into the shop with broken shift forks, burned-out PTO switches, and guys cussing because they bypassed the neutral safety circuit. Nine times out of ten, they were working off a photocopy of a photocopy or some online translation that dropped every third line. That’s why when I say the Branson 6640C 2012 Operators Manual belongs on your workbench or in your cab, I mean it. This is the factory document – 167 pages of what Branson actually printed for the 6640C. Not a reprint, not a summary. The real thing.

If you’re a DIY farmer or a home-shop guy who bought a used Branson 6640C, you’ve probably already found out the hard way that the previous owner lost the book years ago. So you google a procedure, get a forum post that says “just flip this lever,” and next thing you know the hydraulic remote is locked in position and you’re bleeding down the system. That’s the pain point. This manual kills that guesswork.

General Precautions – Page 8 Tells You What Not to Do

The manual starts with a section on general precautions that I wish every equipment owner would read before they even turn the key. Page 8 covers proper clothing, fire prevention, and what to do before you start the engine. It’s not a list of suggestions. It’s the OEM’s warnings. I’ve seen guys skip the part about checking the PTO shield, and then they spend a Saturday in the ER. That page alone is worth the price of the book.

Switches and Levers: Factory Locations and Functions

The chapter on switches and levers breaks down every control on the 6640C. You get the main key switch (page 58), the combination switch (page 60), the F/R shuttle lever (page 60), and the dash meter (page 62). Each one has a diagram and a description of what it does when you pull, push, or twist it. If you’ve ever had a PTO switch that felt dead and you didn’t know whether the switch itself was bad or the interlock was engaged, the manual walks you through the logical check sequence. No hunting. No guesswork.

Pedal Operation: Clutch, Brakes, and Accelerator

The pedal operation section covers clutch pedal (page 70), brake pedals and connector (page 70), and acceleration pedal (page 71). I’ve worked on tractors where the brake pedals were not adjusted to the same height, and that’s a safety hazard on slopes. This manual gives the factory pedal free-play specs. You won’t find that in a generic aftermarket guide. If you’re rebuilding the brake linkage, page 70 is the reference.

3 Reasons to Choose OEM Documentation Over Aftermarket

First: accuracy. The Branson 6640C 2012 Operators Manual was written by the engineers who built the machine. The wiring colors, the hydraulic flow diagrams, the torque specs for the wheel bolts – they are taken from the production line, not from a third-party who looked at a photo. Second: part numbers. When you need to order a replacement PTO switch or a hydraulic joystick for the mid remote valve (page 73), the manual lists the correct OEM part designations. Third: safety. Aftermarket manuals often omit the warning about never engaging the PTO while the engine is off because the clutch brake won’t stop the shaft. The factory manual includes that.

Lever Operation – Right Side and Left Side

The right-hand lever bank includes the mid remote valve joystick (page 73), main gear shift lever (page 73), range gear shift lever (page 74), rear remote control lever (page 74), accelerator lever (page 75), PTO switch (page 75), PTO selection switch (page 76), and the 3PT position control lever (page 77). The left-hand bank covers PTO shift lever (page 81), parking brake lever (page 81), creeper lever (page 82), and MFWD lever (page 82). I’ll be honest – the creeper lever is one of those controls that a lot of owners ignore until they need to creep at 0.5 mph in a feedlot. The manual explains how to engage it without grinding gears. That’s a procedure you don’t want to invent yourself.

Does This Manual Cover the Fuel System?

Good question. The table of contents lists general precautions, warranty, overview, functions, switches and levers, pedal operation, lever operations (RH and LH), others (differential lock, work lamp, wiper, side window, climate control, seat), operation and work, checking before operation, and starting/stopping the engine. It does not include an engine overhaul section or injector pump rebuild. That’s the service manual’s job. But for daily operation, pre-start checks, and understanding each control function, this operators manual is what you need.

FAQ

Does this manual include wiring diagrams?

No. The operators manual covers control functions and basic operation, not electrical schematics. For wiring diagrams, you need the service repair manual for the 6640C.

Will this manual help me adjust the clutch pedal free play?

Yes. Page 70 gives the pedal operation details, including the inspection and adjustment procedure for the clutch pedal. Factory spec is provided.

Is this an OEM reproduction or a reprint?

It is an original OEM manual in digital format – exactly what Branson printed in 2012. Same pagination, same warnings, same part numbers. No third-party content.

What if I need the torque specs for the rear wheel bolts?

That information is not in the operators manual. You will need the Branson 6640C service manual for torque specifications. The operators manual focuses on safe operation and control familiarization.

If you’re tired of guessing where the PTO engagement lever is supposed to be or why the parking brake won’t release, get the factory manual. It’s the same book the dealer uses to train new operators. Access the Factory Manual from AutoRepairManuals – 167 pages, direct from the source.
