I have two "like new" cart caddies that were used for two weeks before being put into storage. The facility closed for business and they sat unused for years before being removed during renovation. These unit were around $7500 each when purchased new. The tire are solid and show no wear. Other that some dust, they are in near perfect condition. I can no longer store them because I sold the storage facility. They are fully functionable but would require new batteries to be at optimum efficiency. Perfect to move around aircraft, carts, wagons, trailers, boats, cars or other heavy equipment. Can modify the front end to suit your requirements. An adjustable 2.5" hitch will bolt to the front control arm for easy modifications for towing. They are rated to push or pull 10,000 pounds, and have variable speed control. These are similar to what they use to push grocery carts but stronger.They are $3500 each or $5500 for both. Can help deliver locally. I can put new batteries in them so that you can have the warranty at point of sale for additional fee.
