I once had a Jim's mowing. ( it is not for everyone) Be careful and get financial advice before buying and be aware of the royalties, they are not cheap and have to be paid whether you make any money or not. The guaranteed income promised is not quite what it seems as you have to take whatever work they throw at you in order to qualify. Also the cost of buying the "run" is worked out by the amount of "mows" you do fortnightly but a lot of people postpone and have it cut every 3 or 4 weeks which gives a false set of figures.
BE CAREFUL.
