Built for contractors and serious DIY remodelers, this jumping jack compactor pairs a 6.5 HP motor with a 196 cc engine to deliver up to 3600 lb. of impact force and a 26 in. max compaction depth so soil, gravel, and trench base material settles fast and stays settled. The four-spring damping structure replaces the typical single-spring rammer to smooth out each blow, lower vibration into the operator's hands, cut fuel burn during long compaction passes, and extend the service life of the machine across deck footings, fence post holes, concrete slab prep, retaining wall foundations, and driveway repair projects. Visible oil and fuel windows make routine checks quick on the job site, with a 0.4 to 0.6 L oil reservoir and a 2.8 L fuel tank that supports prolonged, high-intensity operation between refills. Two 5.4 in. transport wheels and a top handle let one operator wheel the 145.28 lb. tamper between trenches, truck beds, and tight backyard work zones without a second set of hands, and the 29.13 x 18.31 x 42.52 in. body fits in most contractor trucks. Whether you're a pro pouring footings before a slab pour or a homeowner finishing a paver patio and driveway expansion, this vibratory rammer turns soil compaction from a slow hand-tamp grind into an efficient power operation with predictable, repeatable results.
