Good to see another Hercules mower survived the test of time.My mower could do with a re-paint, someone has used a paint brush and the colours are a poor match for the original paint scheme.
The Victa Super 24 I think of like a Truck in the mowing world, lots of alloy in that base, not that this Hercules base is lacking alloy.
The Hercules mower weighs 25kg and 25kg is what a Power Torque Victa with a steel base from the late 1980's weighs also the early Victa 18 with the alloy base weighs 23kg.
The engine number on this Hercules mower starts 294X and I think the original engine should be 305X,(I think 294X and 297X are original Pace and Villager numbers because these numbers are on the mowers I have)
