A 4-ton Cat 304E on the CR compact-radius frame, in basic trim with a standard backhoe bucket. This is the size people buy for residential lots, utility trenching and anything where a bigger machine would spend half its day repositioning.
Dig depth is 3.13 m and reach is 5.22 m, with 30.8 kN of breakout force. The bucket on it is a narrow 300 mm at 0.054 m³. That is a trenching bucket, not a bulk-dirt bucket. If you are moving volume, plan on buying a wider one, because it is the main thing to know before you order this particular unit.
Getting it to site
1.95 m wide, 2.5 m tall and 4.82 m long in transport, at 4 tons. It rides on a standard tandem equipment trailer. Track shoes are 350 mm.
Engine
Caterpillar’s own C2.4, 2.4 liters, 87 x 102 mm bore and stroke, rated at 31 kW and certified to Tier 4 Final. Filters and service parts are shelf items at any Cat dealer, which on a used machine matters more than the spec sheet does.
