City, I don't see anything wrong with a trailer and a sprayer placed inside. Sometimes when spraying weeds at the farm, I've used the reverse. I've taken a 25 gal sprayer on wheels and put it in the bed of my pickup. I can go up and down rows and spray weeds from my pickup window that way (I know that sounds funny.) It's easier to maneuver with a sprayer in the pickup bed vs. pulling it behind. "Does anyone have any experience with atomizer sprayers?" Mike, The sprayer Michael357 has, is an atomized sprayer (just fits on your back). They make small pull behind atomized sprayers too. An airblast sprayer is also a form of atomized sprayer. The advantage of an atomized sprayer is that it takes less water and coverage is better than a hydraulic sprayer (A hydraulic sprayer is simply a sprayer which uses water to carry the pesticide.) Let me explain. The pesticide on the surface of the tree/crop is what you are really after. Generally this is accomplished by using some form of a carrier. Early in pesticide development, powdered limestone or talc was used as a carrier. Crops were "dusted" with a dry pesticide which consisted of a small amount of pesticide mixed with an inert powder. The powder was only used as a carrier for the chemical. Powdered Sevin today is similar to this. The next technology was to use water as a carrier. Mix a small amount of pesticide with water and spray that on trees/crops. This is referred to as a hydraulic sprayer. It works pretty well, except that it takes a lot of water. Plus water doesn't penetrate dense crop canopies very well. As technology advanced, it was discovered "air" could be used as a carrier for a pesticide. This is a bit confusing because it still takes some water to use "air" as a carrier. In this, a much smaller amount of water is mixed with the chemical, "atomized", and blown through the canopy. It has the advantage of less water and very good penetration if there is a good air stream. Essentially the air in the canopy is replaced with air which has fine pesticide droplets. Foliage can deflect air, so it's important to have high air velocities. Although I've never owned a small pull behind atomizer, a potential problem is the small amount of air volume and velocity generated to penetrate the canopy. My airblast is a fairly small one (as far as airblasts go) and I'd estimate it takes about 43 PTO horsepower (minimum) to run it. There's a reason airblast sprayers take so much horsepower. Essentially they are one big pump for the pesticide carrier - air. Air has weight just like the carrier "water" and just like a water pump, horsepower required for an air pump (i.e. fan) is a function of volume and velocity. A good airblast sprayer will "pump" 7000 lbs. of air per minute. The motors for small pull behind atomizers are less than 10 horsepower, so it is puzzling to me how they could generate enough air volume and velocity for anything but small crops (like tomatoes) or very small dwarf trees. Michael's sprayer has a wand of sorts, so the idea is to direct the air in a small amount of area at a time. I suppose it would be a sort of hybrid of a hydraulic and air sprayer. This may be more answer than you wanted, but I find the topic interesting. This post was edited by olpea on Sat, Feb 8, 14 at 13:49

Thanks, I ended up buying the Husqvarna 50 cc after being assured by another dealer that it's virtually the same machine as the RedMax because it's made by them. (I think it's the BT150) I needed to buy this quick because it was a Father's Day gift for my hubby. I got it for $299 at a nearby power equipment store. The store manager told me he had ordered 10 Redmax in early spring and got only three (they were gone within 10 days). He has an additional 10 on backorder for summer. I guess I'll leave it up to my husband whether he wants to keep the Husqvarna or exchange it for a RedMax when the backorder arrives. Working with the local power equipment dealer was much nicer purchase than going to one of the Big Box stores. The owner threw in two containers of gas mix and carried it out to my car. He also mentioned to use only high octane gasoline in the unit. Individual service and no waiting for someone from "lawn care" to be paged!

If I am not mistaken... All Stihl equipment is required to be assembled and serviced when sold(fueled, oiled, test ran). A few people are also correct that Stihl has a 7 day return policy. This is not a dealer policy but Stihl's. If something can't be returned call Stihl. Or If something can't be returned it might not be in sellable condition. Last on my rant is box store returns. Try returning a lawn mower to home depot that has gas in it. You will be told you must take the machine out of the building because they can't have fueled machines inside the store. Some returns people will tell you to go down to the tool rental t have them drain the gas. They are never happy when told to do this. Most of the items being returned are sent to an outside company and checked over as well as repaired. This costs the HD about 40 bucks. Unit is then sold as refurbished. HD return policy on fuel equipment has changed several times over the years but was only 14 days on power equipment. After that machine is sent out for warranty repair. If it is not warranty(which it was usually not) customers will get an estimate to repair. If not repaired customer still pays the $40 estimate fee. You want best price do the small dealers a favor and shop Home Depot. You want service do yourself a favor and shop at a dealer. Also remember just because something is 3 months old does not mean it will be covered under warranty. Example fuel tank vent leaks fuel into air cleaner. Customer removes air filter to make machine work. Debris enters engine. Original tank vent was warranty. But now entire warranty is void. Example customer bought new mower did not put oil in it. Ran engine for 1 min. Realized what he did added oil. Unit runs ok for 6 months. Now engine is seized. Tech finds metal transfer on crankshaft. Customer claims he has had oil in it from min 1and changed it every 40 hours( which is true)not warranty. We fix 16-20 mowers a day. 1-2 warranty requests a day. Warranties approved by tech and mtg a month .............4 last month. I have seen returns on used units. We check them over If nothing is damaged and unit is barley used it gets returned and discounted to the next customer. I have also seen engines warrantied because a customer used straight gas. Obviously this is not the norm. But a good dealer will go the extra mile and talk to distributors or manufactures to try. I also know that the profit that a dealer makes on an fs46 is about 10- 20 dollars. Try asking a counter person for a discount on the cheapest chainsaw or trimmer.

Canguy, You're right, I have never seen a local Solo dealer, but there are several Stihl dealers in my area.
