Silencer's are great Chutes, but I believe you are looking at a $13,000-15,000 price tag. Another Hydraulice out west that is very heavy is Salt Creek. It is made in Lakeview, Oregon. I believe the price tag is still around $10,000. Like most things, If you can write the check, it is the thing to do.......
C &S I believe was mentioned, we used in a feedlot I worked at.... they make a lot of different chutes, I think you still are at the $10,000 area.
I haven't heard what teco is doing lately.
The Stampede is also a great Hydraulic, but I think you are still above 10,000.
There are only two that I am familiar with under $8,000.
Hi-Qual has one that I think is generally $6,000-6500 before the power pack. The thought there is you can run it off of a tractor PTO...If not, the Power Pack is basically a generator you can hook up and run it, I think it is an additional $1,500...This chute is pretty well built and simple, but one drawback is bottom adjustment is manual. They have a pretty good head handler option.....
Powder River came out with what they call a Rancher Hydraulic Chute in January. It is very simple with a Scissors headgate, Side Squeeze and Tailgate all run on Hydraulics. It has a manual bottom adjustment. I think you can find one for around $6,000-6,500 including Power. I have heard of some in Motana selling it for $5,500. Shipping maybe accounts for price difference. It will run on 110 or 220v. Two unique things are the headgate adjusts in and out with side width adjustment (Pivot point moves out with bigger belly cows) and they use the frame as the Hydraulic tank. It isn't represented a a chute for Large Feedlots or Saleyards.
Speaking of Feedlot use, I worked at a 20,000 head one time capacity feedlot that had C&S. C & S were well built, but usually within 2-3 years, stress cracks would show up and need welding. After a bit, these would go to a Doctor area and they'd get a new one.
The worst Hydraulic beats the best manual. All have come leaps and bounds as far as being quiet. hope it works for you cause it trakes a lot of the work out of it!!!!!
