All Case 400 and 200 Series are true garden tractors in every sense of the phrase.
Either one can be fitted with either a sleeve hitch or a three point hitch now that the newer HH-34 hitch became available in 1988. Prior to that, the 3 pt was only available for the 400 Series.
Either Series is capable of powering hydraulic vacuums, chipper/shredders, bush hog style field mowers, log splitters, rototillers and other attachments offered by Case and Ingersoll over the years.
Many owners prefer the Lo Pro 200's for cutting their grass and have no complaints about them when pushing or blowing snow either. Granted, the extra 4 inches of ground clearance provided by the 400 Series can come in handy but that is essentially the difference between these two garden tractors.
You will often find both Series at local ploughing matches with 10 or 12 inch bottom ploughs on the back. Give the 200 a try in your garden but set it up properly first. Tire chains or Ags are needed along with proper weighting.
