“New information” - regarding motor oil I have followed several discussions about what motor oil to use. Now I have some “new” information to share. The biggest retailer in car parts, motor oils, batteries and so on in Sweden BILTEMA (“CAR TEAM”) have many different oils to choose between. Therefore, I mailed them and asked for their opinion. The response was that; the first digit: 5W, 10W, 15W and so on relates to how the oil performs in cold conditions. The lower the digit is the thinner the oil is. The thinner the oils are the better (easier) it will lubricate the engine when cold (when starting up the engine and this will be especially important during the winter season). IN ADDITION, the second digit: (-)30, (-)40, (-)50 and so on relates to how the oil performs when it is heated (after running the tractor for a while). With a high digit, it will stand up to heat better. It will not necessary lubricate better but it will stay thicker. For an older and more worn engine they highly recommend thicker oil. MY OWN CONCLUSION is therefore that a 5W-50 oil would be best for both cold conditions (5W) and for high engine temperatures (-50) especially if the engine is older (and more worn). BY THE WAY, the recommend “all synthetic” oils AND YOU SHOULD OF COURSE always by good quality oils. Sincerely yours Magnus Forssell of Sweden

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
