I like the green and yellow stuff. I use this 24 YO JD 240 to pull my plugger and that 1000 lb roller in the back ground. It does it with ease, and no weights or chains, or ag tires are needed to do so. It has a 14 HP Kawi in it, and 6 speed transaxle designed for this type of work. I pull them both at about 1/3 throttle most of the time in, and that inlcudes up hills ( I have a fair amount of them that I do the plugging with it on). The 318 is even heavier in weight, so it wheel slip is a none issue IME. The 318 I owned sure didn't have any trouble. This 240 is the fore-runner to the 335/345/355 series and has the same exact frame, which is quite large/thick. It also uses the same exact implements.
