Deutz Fahr Agrotron 106-135 Workshop Manual – 696 Pages

Description

If you’ve ever pulled a transmission out of an Agrotron and found out later you used the wrong clutch pack clearance because you trusted a third-party PDF, you know the pain I’m talking about. That’s time, money, and a redo. I’ve been turning wrenches for 28 years, and I’ve seen more than one tractor come back because some aftermarket manual had the wrong torque setting for the PTO shaft. This Deutz Fahr Agrotron 106, Agrotron 110, Agrotron 115, Agrotron 120, Agrotron 135 Workshop Manual is the real deal. 696 pages of factory procedures, not someone’s idea of what the procedure should be. You get the exact same document that goes to authorized dealers. No reprints, no missing pages.

Transmission Overhaul: Power Shift vs Power Shuttle

The manual splits the transmission chapter into two distinct versions: Power Shift and Power Shuttle. Each one gets its own subsections for main components, hydraulic system, gearbox, main clutch, and solenoid valve operation schematics. If you’re rebuilding either type, you need the factory breakout of the hydraulic gearbox and shuttle distribution valve. Section 10 covers it all. The gearbox components are laid out with exploded views and part numbers. I’ve used these schematics to diagnose a shuttle engagement issue that had stumped two other shops. You can learn more about Manual Transmission fundamentals if you’re new to tractor powertrains, but this document walks you through the specific Agrotron system.

What’s Inside the Hydraulic System Section?

Five different hydraulic system configurations are documented: CCLS and LS versions for both the 106-115 HP models and the 120-165 HP models. The manual covers variable displacement pump repair, boost pump overhaul, load sensing valve calibration, and pressure cut-off valve adjustment. For the smaller models, there’s a dedicated gear pump for hydraulic services and steering. The larger models use a combined pump. Each subsection includes the exact pressure specs and flow rates. If you need the user manual for the later 120-165.7 series, check out the Deutz Fahr Agrotron 120-165.7 2006 User Manual – 462 Pages for operator-level information. For this workshop manual, the hydraulic section alone is worth the access.

3 Critical Safety Rules from the Manual

First: never use makeshift tools. The manual specifically calls that out in the safety notes. Second: before starting work, clean the machine thoroughly to remove mud, dust, road dirt, oil, snow, and ice from access steps and grab handles. Third: follow the lifting instructions to the letter. The manual dedicates a full section to lifting procedures. These aren’t suggestions. I’ve seen a tractor slip off a jack because someone skipped the cleaning step. The OEM safety warnings exist because someone got hurt learning the hard way.

Get the Right Torque Data – Standard Tightening Torques

The manual includes a complete table of standard tightening torques for nuts and bolts, plus a section on threadlockers, adhesives, sealants, and lubricants. Don’t trust a generic chart from the internet. The factory specifies which threadlocker to use on which fastener, and the exact torque range. Over-torque a bolt in the rear axle housing and you risk cracking the casting. Under-torque the PTO housing bolts and you get leaks. This section also lists the special tools required for each job, with the OEM part numbers so you can order them. For related axle work, the SAME Deutz FAHR 26.6 30.7 Workshop Manual – OEM Axle Specs covers similar final drive components.

Braking System: Factory Procedures for Trailer Brakes

Brake systems vary by market, and this manual accounts for it. The trailer braking section covers hydraulic trailer braking for Italy and export versions, plus air trailer braking for both. It includes detailed procedures for the compressor, pressure limiting valve, cab suspension feed valve, and both 2-way and 1-way trailer braking valves. The brake master cylinder and brake section are also included. If you’re working on a tractor that tows heavy loads, you need the correct adjustment procedure for the trailer braking valve. The Deutz Fahr Agrovector 26.6 30.7 Workshop Manual covers a different chassis but shares some braking components.

Skip the aftermarket junk. This is OEM.

Frequently Asked Questions

Does this manual cover the Agrotron 150 and 165?

Yes, the manual includes those models as well.

What makes this manual different from aftermarket versions?

This is the actual factory document reserved for authorized dealers and service centres. It includes safety symbols, specific warnings, correct diagnostic methods, and update bulletins from the manufacturer. Aftermarket manuals often skip steps, use generic torque values, or omit entire sections like the electronic system schematics for the transmission. With this OEM manual, you get the exact procedures that the factory technicians use. No guessing, no missing pages, no reprints. You also get the special tool list with part numbers so you don’t waste money on the wrong tool. For learning more about how manual transmissions work in general, see Manual Transmission.
