The Viking looses traction real easy - even on lush green grass. OK I'm trying to go up about a 45� slope but even on flatter ground it looses it - The next door neighbour has as steep a block and a much bigger area and man that comes in to mow doesn't have any trouble getting his ride on about the place.

Mate of mine was expounding the virtues of a diff lock on his mower but I guess that is not a retro fit option. Oh and the tyres are not bald, well treaded but not knobby

Any suggestions?
