    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 Kubota KX040-4 weigh?

    Operating weight: 9,195 lb to 10,360 lb (4,171 kg to 4,699 kg). Standard configuration; 9,195 lb to 10,360 lb depending on cab, canopy and options. Buckets, attachments and options add weight, so check the serial plate.

    How big is the Kubota KX040-4?

    Transport length 16 ft 8 in, transport width 5 ft 7 in, transport height 8 ft 2 in.

    What trailer do I need to haul a Kubota KX040-4?

    One with a payload rating above 10,360 lb plus the weight of any buckets and attachments. At 8 ft 2 in tall it stays under 13 ft 6 in on a typical 60 in flatbed deck.

    Do I need a CDL to haul a Kubota KX040-4?

    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 10,360 lb machine needs a trailer rated well over 10,000 lb.
