TOWING CARTS AND OTHER AT TACH MENTS Tow only the attachments that are recommended by and comply with speciﬁ cations of the manufacturer of your trac- tor. Use common sense when towing. Too heavy of a load, while on a slope, is dangerous. Tires can lose traction with the ground and cause you to lose control of your tractor.
