Collecting antique farm tractors is a popular hobby among both farmers and folks who remember using the old machines.
An offshoot of that hobby is collecting old lawn and garden tractors. Collecting these small tractors is usually a little less expensive than collecting full-size tractors, and it offers the advantage of taking up much less space. It is possible to work on and store multiple garden tractors in a single-car garage.
There is a growing interest in collecting garden tractors, particularly those from the 1950s and 1960s. Collectors acquire the older garden tractors and restore them to near-new condition. Some restorations are excellent. These restored tractors are then displayed at fairs, festivals, old tractor shows, local parades, etc. A good antique garden tractor can bring more now than it cost when new.
If you have an old lawn or garden tractor stored somewhere (or even still in use), you might be interested in this hobby, either from the standpoint of restoring the tractor yourself or selling it to a collector. You can find more information on this fascinating hobby at:
