Descrizione
Small engines earn their reputation in the first three seconds. Pull the cord, and either the machine wakes up or the afternoon is gone. That is why a general-purpose power unit is judged by cold starts, fuel habits and how it behaves after a season of dust, and it is why the overhead-valve single cylinder remains the default answer for anything that has to work without a mains cable.
The Ironheart 210 is a four-stroke OHV single rated at 7.5 horsepower, producing 2.8 kilowatts continuously and 3 kilowatts at peak, with 10.8 newton-metres of torque at a governed 3600 revolutions per minute. Displacement is 210cc, the crankshaft measures 20 millimetres in diameter and 50 millimetres in length, and the bore and stroke are 70 by 45 millimetres. It runs on gasoline from a 3.6-litre tank with 0.6 litres of lubrication oil, and its stated fuel consumption is 360 grams per kilowatt hour, which is the number that actually decides what a day of work costs.
Cooling is forced air through a ventilated heat sink, and the exhaust carries a silencer so the machine can work without dominating the site. Starting is available by hand or by electric starter depending on the configuration, and the ergonomic T-handle with its nylon pull cord is built to survive being yanked a few thousand times. Gross weight is 16.7 kilograms and net weight 14.55, shipped in custom foam packing that resists the compression and drops of a normal freight journey.
An engine that starts on the first pull has already paid for itself.

Where It Belongs
General-purpose engines end up in the least glamorous places and are judged hardest there. A go-kart built in a shed. A water pump on a smallholding where the mains pressure fails every August. A rotavator turning a vegetable plot. A log splitter, a plate compactor hired out by the weekend, a tiny generator set for a market stall, a concrete mixer on a building site without power. Every one of those applications asks the same four questions: does it start cold, how much fuel does it drink, can I get parts, and will the shaft fit the equipment I already own. A 20-millimetre crankshaft of 50 millimetres, a governed 3600 rpm and a 3.6-litre tank answer three of them before you finish reading the specification sheet.
Frequently Asked Questions
Q: What kind of fuel and oil does it use?
It runs on gasoline with a 3.6-litre tank, and it takes 0.6 litres of lubrication oil in the crankcase. Because it is a four-stroke, oil goes in the sump rather than being mixed with the fuel.
Q: How much power does it actually deliver?
Rated output is 2.8 kilowatts, with a maximum of 3 kilowatts, which corresponds to the 7.5 horsepower figure. Torque is 10.8 newton-metres at the governed speed of 3600 rpm.
Q: Is it a hand-start or electric-start engine?
Both configurations exist. The starter system depends on the version you order, and hand start uses the T-shaped pull handle with a nylon cord.
Q: Will the shaft fit my existing equipment?
The crankshaft is 20 millimetres in diameter and 50 millimetres long, the common general-purpose profile. Check the coupling, pulley or clutch on your machine against those two dimensions before ordering.
Q: Does it come with a silencer?
Yes. The exhaust is fitted with a silencer, which is the difference between a machine you can run next to a house and one you cannot.
Q: How heavy is it to move?
Net weight is 14.55 kilograms and gross weight with packaging is 16.7 kilograms, which is a one-person lift for most adults. Packaging uses custom foam, so the unit arrives without the cosmetic damage that loose cartons tend to produce.
