One of my scariest rides on a tractor was a J-D model B like that one that a friends dad had..the "Tricycle" front end and a loader were a risky combo,first time I was allowed to drive it I didn't put the bucket down close to the ground after we used it to pick up a pile of large stones .
I made it across the back lawn ok,but when I went to turn the corner and drive it to where we needed to dump the stones,one back tire came about 2 feet off the ground!..
I put in the clutch and hit the loader lever to drop the bucket and it stopped dead in its tracks..
I almost wet myself after I stopped it..
..
My friends dad said the tall skinny tires didn't really hold enough liquid ballast to make it stable with the loader,and he "forgot" to tell me not to use anything but first gear..the stones had to be hauled about 500 feet,so I used second gear and opened the throttle some..it was just fast enough to be dangerous in second!..
My friend popped a back tire on that tractor once when we hayed a big field ,he ran over a hunk of concrete that had a rebar sticking out of it,an old foundation that wasn't buried completely..the field was owned by the town,and a tractor pulling club used to rent the "track" there to hold pulls,my friend had volunteered to cut the hay & field so they could hold the pulls that weekend--a new tire costed him over $250,and the club refused to even pitch in and help him pay for it!..this was back in the early 1990's too,the tires probably cost more now..
That old two cylinder J-D could really pull though,it sounded like it was only going 400 rpm,but it was practically impossible to stall it..
