Another thing I've been wanting to ask Peter. I know the 1845 and 1850 have overheating Problems, one thing were not to crazy about. Does this happen on the 1445?
A PT-1445?

Ummmmmm Nooooooo the 1845 and 1850 do not have overheating issues. The way the Deutz is implemented by PT is what has the overheating issues. So, the 1430 to the 1850 all suffer the same overheating issue.
There are two oil systems on the PT. One for the engine (which cools the engine as well as lubricates) and one for the Hydrualics. the engine creates a lot of heat and IMO has an inadeqate cooling system for a dusty environment.
The Hydraulics can overheat on all the systems but they have a large radiator and an autmotive grade fan that seems to keep that portion of the system cool, near as any of us can tell cause other than Ken Simolo, I don't think any of us have a way to monitor our Hydraulic temps.
Also, please remember that the 1845 and 1850 are technically mowers first, and are generally purchased by contractors with large crews. So, by being mowers first they tend to work in dustier environements. And by being owned by contractors, they tend to be poorly maintained.

I agree with Woodlandfarms comments.
The problem is that the radiator PT has chosen to use on the Duetz engines is designed for a clean environment. Duetz actually makes a radiator that is designed for a dirty environment but PT doesn't use it in their tractors--several years ago there was a poster who investigated getting the radiator designed for dirty environments but it was very expensive and taller so that it would have required modification of the deflector mounted above the radiator if it would have fit at all.
In my experience the cooling is very adequate so long as the radiator is clean. Simply installing screen over the rear of the tractor--where air is drawn for engine cooling--significantly reduces the amont of chaff that gets into the radiator and extends the interval between required cleaning.
Mowing is particularly stressful on the cooling system because it tends to put a lot of chaff in the air that gets drawn into the engine radiator.

Sorry Carl and Bob. I meant the engine. The machine itself I imagine is fine.
I saw (I think AltavistaLawn used it) 1 or 2 addition fans on the engine, the kind that comes standard on the top of the hood. How does this work?

I have no experience with extra fans but I don't think they will help with the engine cooling issue caused by a blocked radiator.

I think Alta was chasing some bigger demons. He had problems for sure, but they were many, and it was unclear what was causing all of his grief.
Mostly what you hear here is that the engine sucks in chaffe very quickly. But that there are lots of fix ideas. We all just wish PT would
#1, listen to our complaints
#2, make some changes, most of us feel the bottom line would not be effected.

Yeah I agree. Another thing, this is for the 1445 owners out there, I've been wondering for a while, can you get a 1445 with the 26x12.5 tires instead of the big Skid steer type tires?
I'm not in a good mood BTW. I heard YouTube's going under.

Yeah I don't believe. Their saying it's supposed to change in a few days. That was a few WEEKS ago.Ah, the Internet rumor mill.
Pay no heed. It's not true.
Though if this happens, I'm joining the fight to bring it back.
I post all my equipment videos on there and me and my friends are going to start a YouTube series.
But enough about YouTube. Back to Power-Trac.
26x12 tires on a 1445. Could it happen?

You can get them with turf tires, 31-15:50x15, but if you ask nicely and pay, you can get pretty much anything. e.g. wider tires, lashing hooks... They don't make each machine to order, but they are happy to make machines to meet customer needs.
On the overheating issue, yes it happens to 1445s, you need to put on screening or keep a really close eye on your temperature gauge. That said, I have only gotten my machine beyond its normal 200-220F once, when mowing brush with dandelion like seeds. It took surprisingly little time for it to be an issue.
Frankly, I would keep an eye on it. If it turns out to be an issue for you, add the screening, move the PT hydraulic fan on to the side to blow cool air into the engine compartment and buy a larger fan (e.g. 18-20", with a relay) to replace the PT hydraulic fan. Its cheap, and a win-win-win solution.
All the best,
Peter
