DeepNdirt made a couple good points, especially about tilling unknown ground: hitting rocks, pipes, electric cables or whatever is a real hazard. If this garden is new to you, there may be stuff you don't know about under the soil. I wouldn't want to find it with my neighbor's tiller.
I should have mentioned this earlier: I run a 5' Shibaura tiller on my 18 PTO horsepower Mitsubishi. It does fine, although it does require slow going and a ready hand on the lift control in case things bog down when cutting deeply. It has a temperature gauge, and things never get above 155 Fahrenheit on the indicator. (I don't know how accurate the gauge is. Doing light work with lots of idling, pulling a tool car around the orchard and the like, the gauge never gets above 150 degrees, so I'm not really worried.)
As deepNdirt and California have pointed out, it seems like the US style tillers require more power per foot, and the 5 foot tiller may really work your machine. I'd still at least try it. The PTO horsepower ratings should be more or less continuous ratings for our purposes.
For the Nebraska tractor test, for instance, the data sheet for my YM240 shows that they ran the tractor at full power and maximum drawbar pull for two hours continuously, then ran for ten hours (!!!) at full power but 75% load. As long as your cooling system is up to snuff, running the engine at full power and full load shouldn't hurt anything. In fact, it may actually clean the engine out some. Like deepNdirt warned, though, overloading the engine, whether by lugging it or popping the clutch repeatedly to get going or whatever else will wear out the machine faster than using a correctly matched implement.
