Well, here's what happened. I ended up at Early Tractor in Cameron, MO. and got the battery. $333.00. I availed myself of coffee, donuts, cookies, and some other pastries they have. It is a very customer service oriented dealership. I had a problem with the 4WD indictor light on the dash coming on and asked the service manager about it. He got me a wiring diagram and we both agreed that since I replaced the switch on the dash for the 4WD and that the wiring should be OK, and the dash light all worked that it was probably the pressure switch. So I started the tractor, disconnected the wires from the switch and jumped them. Light came on. Tried to clean the switch, etc. and that didn't work. so I'll replace the switch.
