Well John I checked out the Cub Lowboy. Actually there are two lowboys in the lot.
1) Cub Lowboy 154, 1973. Running condition. turf tires 80% tread one tire excellent 1 checked. 3-point. hydrostat. tin very good. Paint - typical. This tractor has been recently moved. Appeared to have been worked on recently.
2) Cub lowboy, 1966. Rough, very rough, hasn't ran in years. Does have very good almost new turf type rims and very good turf tires on the rear. Does have a belly mower. You can check out the 2nd tractor at http://www.schaeperkoetter.com/
under used equipment. Warning the picture is at least several years old - cause the tractor no longer looks any where that good. At the rear of the tractor is an 18 horse Briggs engine mounted on a frame to power the belly mower. You can't see the Briggs in the photo.
They are asking $2500- for tractor number 2. I think it's worth about $300- for the rear rims and tires.
