Marshalltown Gas Powered Spin Screed Assembly with Honda GX35 Power Unit

Description

Watch concrete piles roll forward as a counter-rotating fluted aluminum pipe spins across perimeter forms. The Marshalltown Gas Powered Spin Screed strikes off pervious concrete, low-slump slabs, and slope pours without back strain. A Honda GX35 engine turns roller pipes. Pervious mixes dry fast, penalizing crews that pause roller rotation during strike-off passes.

Seamless schedule 40 extruded aluminum forms the rotating roller pipe, while cast aluminum houses the engine drive transmission and bearing mounts. The 1.3 HP Honda GX35 four-stroke engine operates at 7,000 RPM, spinning the pipe via a chain drive reduction gear. Power unit weight measures 29 lbs without pipe, featuring an agile footprint with T-handles that adjust for worker comfort.

Key Features of Marshalltown SPNRSSAGAS

Pervious concrete specialists, slope paving crews, and commercial flatwork teams deploy this roller screed for circular pours, parking aprons, and highway patch repairs. Search commercial distributor pricing to buy Marshalltown SPNRSSAGAS roller screeds for uniform strike-off on difficult mixes.

• Honda GX35 four-stroke gas engine runs on clean unleaded fuel without two-stroke oil premix.
• Spinning roller pipe cuts through aggregate piles while rolling excess concrete forward.
• T-handle pull design allows upright operation to protect worker lower backs and knees.
• Chain drive transmission provides reliable rotational torque to spin pipes through dense slump.
• Live bearing end support allows smooth pipe rotation along wood or metal perimeter forms.
• Modular pipe couplings permit pipe changes from eight up to twenty-four feet wide.
• Deadman throttle switch halts pipe rotation the moment the operator releases the grip.
• Works on pervious concrete, standard slabs, bridge decks, and circular slope pours.

Roller Drive Torque Dyno Metrics

Pipe runout measures under 0.030 inches TIR across a sixteen-foot roller length. The Honda GX35 engine maintains 6,800 RPM under load, turning the roller pipe at 350 RPM through chain reduction. Counter-rotation creates aggregate cut action that consolidates low-slump and zero-slump pervious concrete without aggregate separation. Drive chain tension holds steady under high resistance without tooth skipping. Engine cylinder head temperatures stabilize at 265 degrees Fahrenheit during continuous afternoon pours in warm summer weather.

Roller Strike Operator Service Realities

The upright T-handle lets two operators walk forward comfortably along outside form rails while guiding the spinning pipe. The deadman throttle control responds with positive mechanical release through thick work gloves. Do not buy this roller screed for wet-screeding expansive warehouse bays lacking rigid screed pipes or form rails. Pervious concrete installers and bridge deck paving crews extract immense time savings here.

• Wash concrete paste from the aluminum pipe and drive chain right after every pour.
• Lubricate drive chain links with dry chain spray every twenty operating hours.
• Check engine oil levels before each pour and change oil every fifty hours.
