Cat 428, 432 and 434: controls, stick options and upgrades
The 432's seat controls differ from optional 428 and 434 pilot pods
For the European 07A generation, Caterpillar separates seat-mounted electro-hydraulic controls on the 432 from mechanical levers and optional pilot pods on the 428 and 434. The seat-mounted arrangement lets the operator use the loader or backhoe functions from an offset seated position. A touchscreen does not turn the other control packages into that system.
The larger backhoe boom cylinder is standard on the 432 and optional on the other two models. The longer stick option also belongs to the 432 in this comparison. Those choices matter when a quotation offers an unspecified lifting upgrade or maximum digging depth: identify the cylinder and stick before comparing the figures.
The 434's equal-size tires and available steering arrangements need their own inspection. The European equipment list specifies all-wheel steering, although the same brochure's technical steering row says front wheel. That document conflict is retained below; establish the actual machine's steering modes instead of assuming its model name settles the question.

Cat's side-shift upgrade guide identifies machines by serial prefix, then separates mechanical controls from pilot and electro-hydraulic controls. Its additional-function kits use different hardware: a mechanical pedal and diverter on one arrangement, a joystick and diverter on the other. Similar-looking auxiliary couplings are not enough to select the kit.
The guide also distinguishes installing one-way hammer lines from adding two-way operation to a machine already fitted with one-way lines. Boom length changes some applications. Record the existing line routing, control type and serial prefix before asking for a conversion quotation.
Several kits require dealer activation as well as installation. The touchscreen replacement requires Cat Electronic Technician, and the powershift-to-autoshift upgrade has software-enabled features with possible additional hardware. A used display or transmission switch sold on its own does not establish that the retrofit will function.
Source: Caterpillar AEXQ3131-03, side-shift upgrade applications and activation requirements.The 432 North American sheet uses a different equipment basis
The separate 432 sheet specifies an estimated operating mass for an extendible-stick machine with a deluxe cab, multi-purpose loader bucket, hydraulic quick coupler and counterweight. Its maximum ROPS mass is another limit. Neither value should replace every European standard-stick operating figure.
The same sheet lists rear and front axle housings separately from their planetary compartments, so a housing refill is not a complete axle refill.
