Duffer,
I appreciate your response, and I don't doubt that your trailer does handle that well.
What I can't understand is that your trailer looks a lot like mine, the axles seem to be in approximately the same position, etc, and yet my trailer, with 4 ft sidewalls, weighs only about 2800 lbs.
Therefore, if I have it altered to add the 1950 lb JMS grapple and the 650 power unit on the front, the tongue weight will be increased dramatically and unacceptably.
My welder suggested that we could add another axle in front of the existing two (making it a tri-axle). But yours apparently does fine with two axles. Perhaps it is balanced differently from the manufacturer, but it just looks so similar.
I will talk with the manufacturer and try to acquire some insight from them. If it looks like the cost of alterations to my current trailer will be less cost-effective than purchasing the entire grapple trailer package from JMS, then I will go that route.
I had a little epiphany last night that, with this grapple trailer, I could place and remove my SC252 stump grinder from the back of my bucket truck. I plan to design a "bra" for the grinder with canvas straps attached to a large steel bracket that can be grabbed with the grapple. The stumper can then be placed into the yard with no need for spacey ramps or tailgates on the the truck.
Any additional insight into this tongue-weight issue would be greatly appreciated.
Thanks,
Nate
