Early morning this past Saturday I drove it home. The top speed is about 17 to 18 mph. I've been so busy with the irrigation pipes I haven't had a chance to do anything else with the tractor.
I did check and the tractor will just fit in the pole shed with about a foot to spare. That's good as the tractor has a block heater and the pole shed has electricity. I just need to find time to clear out one of the sections of the pole shed to drive the tractor into.

I also bought a new bale spear for the tractor. I brought the bale spear home using the pickup. While the salesman and I lifted the bale spear into my pickup, I had to use a couple of boards to slide the spear from the pickup to the ground. I haven't had a chance to test attaching the spear to the tractor.
