Cat 825 versus826: tips, waste guards and blades
The 825 spreads soil; the 826 protects itself against waste
Cat's 825 uses chevron tamping tips to work a soil lift. Its cleaner bars act on the drums in either travel direction, and their adjustment matters when material carries around the wheels. Inspect the bars and their replaceable ends with the tips.
A photograph of unworn tips alone will not show whether the cleaning equipment is correctly set for the fill.
The 826 adds protection for a landfill environment. Cat describes axle wrapping and seal guards, guarded fluid lines, a fine-mesh air inlet screen and ventilation arranged to reduce trash entering the engine compartment. Check those features underneath and behind the wheels.
Missing guards are not cosmetic omissions when the machine will return to handling wire, film and other wrapping material.
Blade shape changes the haul envelope as well as capacity
For the 826, straight, semi-U and U blades have separate dimensions. The largest stated capacity is not simply the straight blade with taller side plates: overall length, cutting-edge position and clearance also change. Specify the installed blade when requesting a transport quote.
Include the rear radiator guard in the length measurement because Cat's blade schedules explicitly use that configuration.
Wheel choices have their own weights. Paddle, plus, combination and diamond groups should be identified by their actual equipment records, not guessed from the model's maximum operating weight. Tip height and outside wheel diameter are different measurements.
Wear at the tip changes the working surface without turning a wheel-group mass into a complete-machine mass.
Read compaction mapping as a measurement with a defined purpose
The 825's Machine Drive Power system measures rolling resistance and relates it to soil stiffness. Optional mapping ties measurements to position. That is useful for finding an uneven pattern across a lift; it does not mean the screen directly weighs the soil or establishes every project's acceptance density.
Agree on the specified testing method and calibration before treating a displayed color as permission to place another lift.
Product Link records machine information such as location, fuel use and events. Those records answer a different question from mapped compaction coverage. Request both kinds of history where fitted, rather than accepting a location trace as proof of how uniformly the fill was worked.
On the 825, the left pedal can override throttle lock while providing braking and transmission neutralizing. The 826's lock-up torque converter and travel ranges deserve a separate demonstration. Similar C15 power ratings do not establish identical driveline operation.
Compare the equipment schedule for each machine before attributing a change in speed or response to a fault.

Short answer
The Cat 825 and 826 are closely matched soil and landfill compactors that Cat lists separately, with 2 listing entries: 825 and 826. Listed weight is 16,167 lb / 7333 kg. Earlier component-weight summaries must not be used for hauling: the operating specifications distinguish complete-machine, blade and wheel-group masses.
