My grandfather never ran a mower on the 424. He kept the dog-eater, lawn roller, dozer blade and cart from his 2-wheel tractor. By the time I got to drive it, the dog-eater was replaced with an MA-style blower and we had a pull-behind lawn sweeper, too. It was in rough shape when I took an interest in it, and in high school I got my dad to replace a bunch of worn parts, and I stripped the whole thing down and repainted it (not accurate colors, I wish that I had). It had the classic "broken/missing fins" on the flywheel from being backed into something. It always shook when it ran and my dad didn't want to spring for a new flywheel.
When my grandfather died, my dad started using it and it spent its whole life pulling the cart around. We had a wood-burning furnace in those days, and we would drive into the woods and load up the logs from trees my dad felled the previous year. The cart overturned on the hills a couple times, and had to be re-built at least twice. The only thing original was the axle and tongue.
Here is the tractor in 1988, repainted and with the cart on the back:
The Snapper mower in the background is what my dad bought to mow our 2 acres. He said the "mower deck alone for the tractor cost more than the Snapper."
Here it is with the snowblower installed.
My dad had used the blower on the tractor until the Blizzard of '78, then he got a walk-behind. He said he "got tired of a lapful of snow" whenever he used it. I thought the skids were wonky, so I fabricated some casters. I never got to blow much snow with it, though, as the front drive shaft sheared off (from a bad repair job) after about 10 minutes of use.
