Tractor madness

This is an account of the tractor experences tom and I have had so far. So about two or three weeks ago. I had my first gasp moment going down a fairly steep hill and i changed gear and i couldn't get it into the next gear. The tractor picked up a fair bit of pace and i did swear because at the emd of the hill is a main road.
The next moment of tractor madness was, i got the tractor beached on the same road but slightly further up. I took the turn to wide and got the bottom of the trailer dug into the road surface about 5 or so centremetres. The tractor was stuck right i n the middle of the road so there was only one car able to get past at one time. Luckly the road is a rather quiet. I ran to the orchard up the road because i didn't have my mobile phone on me so i had to us Adam's. Dave sounded rather relaxed on not bothered when i spoke to him and he said he was on the way. It took about 5mins or so to get the tractor out but he did it in the end. The best thing was he didn't shout and wasn't annoyed at all. He told me how to stop it happening again, i said i was sorry and no more was said.
The last tractor occurence was performed by Tom. We were picking golden delicious near daves house and the weather was appaling, one minute it was hammering down the next the sun was beaming, Tom moved the tractor down the row with about half a bin of apples and touched the brake, Next thing i hear him shouting "Raymond, Raymond, Raymond" (in a really girly voice). I look down to see the whole tractor sliding toward the row of trees on the right hand side. The skidmark was about 5 metres long and he was moving at an alarming rate, i think he must have been travelling no more than 3 miles an hour, but the sheer terror in his voice was great. I shouted to take his foot of the brake which he did but he still slide towards the tree. In the end he pulled the stop button on tractor and the whole ordeal was over. He still had about 2 metres from the tree so i imagine he would have had time to try practically anything before impact. We had a really good laugh about it which was nice to take the edge of his impending death (not).
Later i realised i'd left it in 2wheel drive mode, sorry Tom.
