Arhhhh Ill assume scarscasium...
No its a good old Brigs and Strat 4 stroke... (3.5HP )
Was going to buy a bottle of oil from the mower shop for $14.95 (1 litre) and the guy at the counter said "Castrol GTX is exactlly the same stuff"
Sucker, did him self out of a sale, but i did buy new blades... And might I add, what a bastard to change... At least you can just tip a lawn mower to get under it.
