Recollections and a pirep of two great airplanes

This summer, I have been fortunate enough to get back into ag flying. I started the year with the intentions of being a part-time, fill-in guy. That lasted around a couple of weeks until the work really started coming in and it has been pretty much wide open running since.

Started the year and continue to fly a Ayres Turbo Thrush with a 510 gallon capacity powered by a -34 P&W. This is a great airplane. It is big and has lots of room in the cockpit, flies very solidly, carries a load well, and what I really like about it is that it has a low profile ( sits low to the ground, therefore much more comfortable working around things). It is a little "twitchy" on takeoff and landing but an all around workhorse.

About three weeks ago, I also started flying a 602 Air Tractor. Both the Thrush and Air Tractor were designed by Leland Snow, but they are two totally different airplanes. The 602 is a much bigger plane than the Thrush, starting with a 630-650 gallon capacity. The controls are really light, and it is a joy to fly. It is powered by a -60 P&W and that is all the engine that it really needs. It will get off the runway very well. The only thing that really takes some getting used to is the constant use of flaps. I told someone the other day that you had to use a notch of flap just to taxi the thing. In all seriousness though, you do use flaps on take-off, every turn around and on landing. The ailerons droop when the flaps are extended. A very fine airplane! This is an airplane like the one that I ran in my business and I have around 6,000 hrs in them. I am sold on the airplane.

Only problems I've had (so far) this year, The A/C went out in the Thrush for a couple of days and I cooked for a while. It is really miserable in there without the air. Other little problem, I accidently got in the wrong field and gave a farmer a free fertilizer job one morning.:)

All in all, So far, it's been a good year. I have flown about 350-400 hrs and I have really enjoyed myself.

Just thought I'd share.
 
Glad you are enjoying yourself!

Nice write up... would love to see more on each airplane when you start to slow down.
 
Snow designed the Thrush line, and obviously the Air Tractor. My question has always been, did the various people who have owned Thrush pretty much leave well enough alone, or have they continued to refine the airplane? It sounds as if the Air Tractor is the better product. How many hours in a Champ would prepare me for the AT-602?

Did you ever get any time in a 401 with the R-1340? What is it like? Final question - what does the temp in the cockpit get to without the air? With the air running, how cool can you make the cockpit?
 
My dad got a free fertilizer job last summer by our local aerial appication business. He was stoked, another company was set to do the very same job two days later.

it looks like so much fun

The airplane is basically the same as Mr. Snow designed it. I do think that Fred Ayres was the owner who started putting the turbines on. The 660 has been designed since Mr. Snow sold the company also. After flying both, I really like the Air Tractor line better.



Waco, I really believe that if you are truly proficient in a small taildragger such as a Champ, you could fly this airplane. It really is a easy handling plane. Not twitchy at all.

I do have around 50 or so hrs in a 401. It is a good airplane that will haul 400 gallons well up into the morning when the temperature starts to climb. A great starter airplane. And it is built with the Air Tractor quality. I cant say anything negative about Air Tractors other than the fact that they are so expensive, but I don't worry about that part now.

Don't really know what the temp was, but it's like riding down the road with the heat on medium and can't roll the windows down. That's about the best way I can explain it. Luckily, it's fixed now. The Thrush uses an aftermarket A/C and it helps a lot but isn't anything like a car A/C. The Air Tractor's come with a factory A/C installed and it is much better.

I screwed my edit up,, Here ya go.

Waco, I am talking about you taking off and landing the thing with Champ time. NOT ACTUALLY WORKING IT!
 
Great PRIEP om 2 great aircaft, T-Cart! I worked for the Texas Dept of Agriculture right out of college with my territory consisting of the southern end of the Texas Panhandle and I spent alot of time with some of the operators in that area. Just curious, does anyone still use the Dromador aircraft? I saw one once and don't really know anything about them. Funny story, I nearly saw 2 operators come to blows when debating whether the TPE-331 or the PT-6 was a better engine on the front for ag operations...

hill country, I haven't seen a Dromadier around here for several years.

The way I can best explain the difference between the Garrett's and the P&W's is that the Garrett will cost less to get into but will cost more through the run of the engine. The P&W is the opposite, It will cost much more to buy, but will cost less throughout the course of it's run.

I have ran both a considerable amount of times on various ag planes and the both cost around the same for , say a five year run. $$$$$ LOTS!!!!:)
 
I would LOVE to do this:

That just looks way cool.....

And then there's the MikeD version.....

While we're on Ag planes, I always thought this particular craft was rather interesting looking. Apparently it'll seat pilot + 5 in lieu of a hopper, but that seems like it would be kinda cramped! Looks kinda fun to fly though.....

I would love to do ag flying, and I'm very jealous. Great post though.

Can you use beta and reverse with your PT6?
