Well,
We had the Original hooked up to the sled for the first time today. My son pulled it once in the 1050 (Kids) class and I pulled it in the 1050 (Adults). It only wieghed in at 850lbs so, we were giving up a LOT on weight.
It has 8.5" ags on it and I was curious to see how the belt would do under those conditions. Turns out, that it did rather well! Never heard a squeak out of it, but the tires sure did spin.
He pulled in low and I pulled it in 2nd. He pulled 102ft and I pulled 96". (It was a LONG drive home)
I've got a line on a set of 10.5 ags and I might try them next month. Overall, the little tractor did fine. In fact, I'll be learning to throttle back a little bit. We've been thinking at some point we'll do a ring/gasket job on the ol' girl and while we were talking to a guy there, he said he had a good engine that he would GIVE us so that we could go through that one while we still have the engine running in ours! It was a good day and Jr. said he had a great time. What more could you ask for?
