My wife's uncle across the street has a Cub, in fact it is the one that got me onto this bug.. kind of infected me with the Cub Virus..
He too says the Cub isn't much for anything... but I gotta wonder cause he has had it now for almost 30 years... so he must like it
A well tuned Cub with a good sound engine can handle most mowing chores from all that I understand. From the 42" bush hog type of mower to the larger 59" finish mowers, the Cub can do it nicely. But don't for a moment think that it is going to perform like a 25 hp or more tractor cause it won't. The Cub when used properly within it's operating envelope is a great tractor.. after all it was designed for the 40 acre and under farm, meant to do all that the truck garden farmer, tobacco farmer and others who farmed in this size acreage needed done.
Many of us regularly use our Cubs to plow snow, landscape our yards, grade/level private roads, plow, harrow, cultivate our gardens and harvest crops. A number of us use our Cubs to pull ground driven manure spreaders, potato diggers and other implements. So, if you are really wanting a Cub, do your due diligence.. do the research, ask our members what they do with their Cubs, how they handle the 59" mowers etc., and get a good feel for what year/style Cub you want. There is a slight horsepower difference from the original Cubs that were introduced in 1947 and the Cubs at the end of the production run in the 70's ... but I don't think that is going to make a lot of difference. With a good well tuned engine a Cub should be able to handle a 59" finish mower.
