One exception to this would be the Cub. I've had a Cub for a few years (a '51) and was used to checking the oil with it's dipstick, so when I got my '51 H, i looked and looked for a dipstick. Finally resorted to checking the manual ( :lol: ) and lo and behold, no dipstick!Matt Kirsch":hfdsahew said:IH didn't add a dipstick to tractors until the 350. Older ones might have it if the owner added it, or the engine was replaced with one out of a combine.
