Long story short the exhaust fell off the McCormick,the fitter is welding it up but re fitting it is a pig as there is a pipe that runs to the air filter box from inside the upright which is causing a bit of trouble.I'm sure I read somewhere that it doesn't do much so the question is can we dispense with it blank it off and weld it all up and put it back without.

It's a mtx 150.over to the learned ones.

as long as its not electronically connected just block it off
is there a temperature controlled valve where it joins on to the main air inlet ?
sounds same as our MC 135
If you like I will pull the pipe off on ours and see if it runs better
been meaning to do that anyway

Not sure if there's a valve as didn't look before I left but if you don't mind giving it a try would be interesting to know if it makes any difference.Just looking to make life easier and get it back together quicker.It's rotted off where the silencer joins at the bottom and then also where the little pipe comes out of the big bend.

Well I took it of and gave it a run up the road and I think it might actually be a slight improvement . It is a little bit sooty so if its meant to just let it draw hot air to warm up quicker it must have a leak from the exhaust
. Ours pulls ok when warmed up or with a 4 furrow plough on but its a dour brute on the road . I think I will also leave pipe of for a week to evaluate and see if its better left of altogether
do no harm just blanking it I reckon

Sounds like its the pipe that sucks the dust out of the air filters pre cleaner section by using a venturi effect where the pipe goes into the silencer. Its safe to block it off if thats what it is.

Our dear old TW has a sort of metal flap valve in a housing on the side of the filter and at about 16,000hrs it started flapping at tickover making a sound like the old exhaust rain caps do. Simple solution was to weld a washer on one end of the 1" steel connecting tube with its hole welded up, refit the pipe and clean the air filter a bit more often
