Last year at Travis' I was loading the old case 220 backwards onto the trailer behind my buddy's cub. He said stop when I was close enough, jerked the directional lever too much and launched me and the tractor off the trailer. Knocked the ramps off as well and I landed 5ft from the trailer and that was something. The tractor is hydraulic driven, not hydrostatic but similar. the forward/reverse valve is in need of replacement and makes the tractor jerky to drive. My little exageration was enough to send it in the full forward position and with still being at full throttle for loading it went all out. That topped the day off because I had it tilted too much in the field and was there a smoke show of oil burning. Some may remember it, whole big cloud. The engine is reverse of cubs and it has a fuel pump. The diaphram in the pump was torn slightly before that and let all that engine oil in with the fuel, and gas in the crankcase. Combined it was a big cloud of smoke that took up a large portion of the field. Looked like it had started on fire but didn't. My friend thought it was halarioius of course and I still don't here the end of it.
