Let neighbor borrow tractor for a couple hrs, and he came over and told me the tractor is overheating. Noticed the fan belt slipped off, so took it back to the shop and slipped it back on by loosening the alternator and then tighting it back on and bolting it down. Ran it for about 30 min before it slipped again. Anyone else have this issue? Have 58 hrs on it and never had any problem with it.

I would say you have a bad water pump, alternator, or belt.

Check everything.

58 hrs on it and a neighbor is using it.

Wolfman's advice on the technical problem is undoubtedly correct.

I will be waiting for others' reaction to loaning an expensive machine.

In Canada, asking a farmer to loan another farmer a big socket is a touch and go proposition, a tractor, no one would even dream to ask.

If my brothers need tractor work, I will go and do it but they will not have the tractor. In the end something is misused or broken and you have the expense and time to fix it.

Rental places exist for people who want to borrow tractors!!

What did your friend borrow the tractor to do? Could he have ran a tree limb or something in the engine compartment and bent something. I have seen belts come off if the pulley is bent in a little making the area where the V-belt rides narrower causing the belt to be pushed up.

Too many time you have to go get your borrowed item back so YOU can use it!!!

Very seldom do things get returned in good time and condition.

I did loan a soil puleriuzer to Daren Todd. He came up 350 mile to get it, replaced bearings and returned it...and at that time had only met him on this form! Thanks Daren. An example of charactor!

I can never figure out why I can use a tool for years without a problem and the minute you loan it out something happens to it. Folks cannot even clean the tool before returning it. I will not loan out anything anymore, even to close friends. I just do the job for them.

I borrowed a friends electric chain saw many years ago to cut joists for fitting in a beam. I did not want to use my gas saws for CO reasons.

Saw was making noise when I was finished with the few cuts that were required. Returned saw clean and with two new bearings.

Yeah same here, I do not loan tools anymore.

My dad needed to use my tractor (MF1145) to do some loader work at his place. No problem, come get it, I don't have a trailer so bring yours. MONTHS go by, and I needed it for my own work around my place. So I asked if he was through with it. He said my brother's got it. Great. Y'all don't know my brother, but he destroys everything he touches. Besides that, I was never asked if he could borrow it. So I am mad by then. I went over there, as opposed to calling, to get it. Tractor not there. It was on loan to his friend, who by the way also borrowed my brother's old Belarus and actually broke the tractor in half, cracked the clutch housing all the way around. Ruined it. So by now I'm totally PO'd. I told him to go get my tractor from his friend, deliver it to my house by 9:00 pm the next day, or I'm going to call the sheriff and report it stolen, and then they can deal with it themselves. It was at my place when I got home the next day, but the clutch is SHOT, loader valve joystick broken off, 3ph leaks down, and left front tire was totally flat.

So yes, I will never EVER loan tools out again.

I did have a 4701 on the shop a while back with similar issue, fan belt. Came to find out AFTER the fact that the operator had knocked the belt off at some point by using the tractor for a dozer, clearing timber, probably a limb or stick or log knocked the belt off. They reinstalled it but it never stayed on after that. When I got it, I removed the old belt and it would not hold it's position. Somehow it had a memory, in that it wanted to "roll over" by itself. Replaced with new belt and that solved his problem.

My choice of words is not the best but it feels heartwarming to see so many members having my reaction to lending equipment.

It is like lending money. If your friend really needs it and you have it GIVE it to him, no loan and in that way your friendship of years is not destroyed over $.

For me lending:
Smashed boat propeller: I did not know it was shallow over there.

Army truck stuck in a creek full of water: I thought those trucks would go anywhere.

Cars: last Friday my youngest brother, who is 60, asked to borrow my 5 std standard Pontiac Vibe. When he got home he realized he was driving with the parking brake on. The red light on the dash ignored. Really good for the clutch and the rear drum brakes on a 2006 car which is all I have.

My M7040......... if you need something done and I like you & have time I will do it for you but I drive.

And then the reverse. A.... hole of a neighbor, teacher and local municipal politician, conned my teenage son into looking after his dog while they went to Florida for months. A large female German Shepherd with breast cancer, very obvious once they had left and then my son said what is wrong with the dog.

The Vet bill was about $1,500 20 years ago when that am't of money was not lying around. Neighbor returns in the spring and I ask for my $. Well really it was not his dog he was just looking after it for someone else and when he sees them again he will ask them to pay me. I am still waiting. My only perverted satisfaction was when his high school teacher son was arrested for exchanging lewd material with a student.

Most of the time I'll go with my gear and do the work, fortunately I haven't had too many problems, have had some tools never returned, on the few occasions when I have had the need to borrow myself, I have generally serviced or repaired the equipment for the owner and sent it back in better condition than when I borrowed it.
But I know that when I loan my trencher out next it'll probably blow a hose, I can't afford to have everything in A1 condition.
Sometimes we forget that things do fail, and they may just fail when someone else has the machine. If it happens when you have it yourself, you just go ahead and fix it and forget about it. As long as it's not abuse, we need to just think that it could have happened any time and move on. If it's been abused, we fix it and remember not to go there again!
Back to the OP problem, once a belt has jumped/flicked off or twisted, it's likely to happen again, sometimes it may be just the belt, but more likely stemmig from another issue as NIW suggested.
