    Federal rules: a combination with a GCWR of 26,001 lb or more, towing over 10,000 lb GVWR, needs a Class A CDL for commercial driving (49 CFR 383.91). Equipment of 10,000 lb or more needs at least four tiedowns (49 CFR 393.130), with a combined working load limit of at least half the cargo weight (49 CFR 393.106). States can add rules.

    Common questions

    How much does the Caterpillar 308 CR weigh?

    Operating weight: 18,493 lb (8,388 kg). Standard configuration; 16,542 lb to 18,493 lb depending on cab, canopy and options. Buckets, attachments and options add weight, so check the serial plate.

    How big is the Caterpillar 308 CR?

    Transport length 21 ft 7 in, transport width 7 ft 7 in, transport height 8 ft 4 in.

    What trailer do I need to haul a Caterpillar 308 CR?

    One with a payload rating above 18,493 lb plus the weight of any buckets and attachments. At 8 ft 4 in tall it stays under 13 ft 6 in on a typical 60 in flatbed deck.

    Do I need a CDL to haul a Caterpillar 308 CR?

    For commercial hauling, almost certainly: a trailer rated over 10,000 lb towed by a truck whose GVWR brings the combined rating to 26,001 lb or more requires a Class A CDL (49 CFR 383.91). A 18,493 lb machine needs a trailer rated well over 10,000 lb.
