    i don't need a new one, just figured it could come in handy when hauling mulch and gravel etc.... do you need a cdl to drive a dump truck? say 650 or 750? also, some i've read say 9 speed, is this similar to my 5 speed truck? thanks for all replies.

    You need a CDL to drive a truck over 26,000 pounds gross vehicle weight. A 9 speed transmission is a Road Ranger type tranny. It's not syncronized, meaning you have to match the input shaft speed for the road speed of the truck. This is hard to explain, but for example you are going 10 mph in 1st gear at 3000 rpm. If the truck turns 2000 rpm in second gear at the same speed, when you shift from first to second the input shaft of the tranny has to be turning 2000 rpm before you can shift to second. A nine-speed has two ranges, low and high. You start in low range, shift through the gears, flip the range selector to high range and shift through the gears again. If you buy a truck with this type of tranny and have never driven one, you really should get an experienced driver to help you because you can tear one up pretty easily when you're learning. Having said all that, buying an old truck like that is really a gamble. You may find one that runs and works good for cheap, and it may stay running for a long time. Or, you may buy one that runs good for a week, and then you break a motor, injector pump, tranny, clutch, rear end, hydraulic pump or any other major component, and then you are looking at serious money to fix it if you can't do it yourself.

    You looking at a medium duty dump truck then if you say 650 and 750 which are both 3 ton trucks rated at 26,000lbs. As for owning a medium duty dump truck it will be expensive because you have insurance etc. Unless you plan on working the truck atleast 3-4 times a week it maybe worth it.

    If you are a small landscaper stick with a F-450 or F-550 sized truck atleast you can use the truck as a daily driver or a general work truck it doesn't have just one purpose.

    As for a 9spd who ever told you its like a 5spd is pulling your leg. You probably won't find a 9spd in anything but a truck with a 30,000lb and greater gvw. Any truck that you would be looking at if you plan on sticking with a 26,000lb 3 ton will either have a 6spd or 5+2 gearing.
