I can not get enough traction to stall a 10HP engine in 1ST gear without a creeper,,,,,,
What would you have to do to get enough traction to worry about the creeper??
Hook it to a weight transfer sled??
I would not worry about the creeper because the tractor will always be traction limited.
I feel the creeper will only be useful to change speeds, not add wheel torque.
The creeper will be great for a snow blower, or a tiller, or my use,
letting the tractor crawl across the lawn in 1ST gear low creeper at an idle by itself as I throw in sticks that fall from the trees each winter.
