Comparison RAYCO C100, ASV 100, CAT 287C with HM312 or HM315

[JAGD44]

I would like to know which of this tractors is the best for mulching, according to the price. Is it worth it to buy the Rayco C100 instead of the ASV?.. or I can use the Caterpillar with the attachment with no problem? ( and I can do 2 x 1 work ). I'm planning to use this in an area that was previously cleared and use to have grass, but now it has about 6' to 7' of undergrowth and in some areas trees between 1-4 inches diameter. Thank You.
