Exhaust
As far as it's possible, you would want to have your minitractor make as less sound as possible and a broken exhaust can ruin this for you. At least try to maintain the exhaust as best you can. If it's really neccessary to get a new one, you're at the right address at Tracpartz for a new exhaust or gaskets. Some of the brands that we have are Iseki, Kubota and Massey Ferguson.
