Frequently Asked Questions
How much does the CAT 420 weigh?
The CAT 420 has an operating weight of 17,271 lb and a 91 hp engine. Cab, counterweight, tracks, and attachments can move the real weight of a given unit up or down from this spec figure, so check the serial plate or the OEM spec sheet for the exact build before booking transport.
What size grapple bucket fits the Caterpillar 420 Backhoe Loader?
The Caterpillar 420 Backhoe Loader runs a 1.25 cu yd loader bucket, so a root or rock grapple in roughly the same 0.5–0.7 cu yd class is the right match — typically a 60-to-66-inch grapple. With 91 HP and a 17,271 lb operating weight, the machine has the hydraulic flow and front-axle weight to run a single- or dual-cylinder grapple without front-heavy handling. Always confirm the quick-attach plate style and auxiliary hydraulic coupler match your unit before buying an attachment, since loader mount standards vary by model year.
