    falling debris in the bush. Exhaust pipe goes thru them. One D7 I ran had pipe flush and a heavy plate trap door that you had to remember to open.Closed it kept the rain out. Cheers LD

    I have seen it where the pipe from the hood goes inside a fair bit larger pipe coming down from the sheet which is welded and terminated flush with the sheet so there is room for the lower pipe to move around and all you see from the top of the sheet is a hole. I don't know how they keep rain water out of the muffler or if it is necessary to keep water out, this is on a D6M.

    Yair . . . Here again machines have evolved differently in different places to do basically the same job . . . It seems I rarely see an American/Canadian tractor set up with a proper protective canopy which we consider to be essential for timber work Cheers

    Just to keep debris off the hood. Most cats here have them as most operators will find themselves in the bush at some point. Pipes go up and terminate at the top of the canopy. Mines older but still the same principal. My 7e the pipe is large enough that a gallon ketchup can fits perfect over it. Never a drop of rain gets in there and its quick and easy for when I transport it too.

    When you get a limb weighing a thousand pounds fall on your canopy, you will be grateful for the strong canopy

    This is the way we do it. Just remember to cover the opening with some sturdy mesh to stop sticks falling down the chimney. Doesn't take long to set em alight. Cheers, Greg

    Keeps the hornets nests from falling on you as well!

    How thick of sheet metal is used on top??

    Holy mobile home!! Is there shingles on top of that, and drapes on the inside :falldownlaugh Looks like someone had a few too many beers out in the shop one night and got frisky with the welder :lmao

    It's usually pretty heavy metal. Covering the top would also help keep heat in in the winter. The best time to clear is when the tree's are frozen.

    By contrast the heavily armored ones like that that I see in California are set up to work brush and forest fires in the heat of summer with full AC and glass around the operator. They have mesh covering everything and even so things still usually get broken after a couple of days on the line from sticks and branches poking in every which way.

    Yair . . . Those scrub tractors were built to run around the clock in heavy dust with some times zero visibility. They were constructed so any tree or branch that came back across them was of no consequence to the operator or the tractor. As mentioned up thread by .RC. thousand pound branches falling across them were an everyday occurrence when working certain types of country. There is no pussy footing, second gear full throttle, hit decel as the pusher makes contact, feed it to her and if the pusher happens to split the tree and half of it comes back across the tractor we used to call that 'ringing the bell'. Biggest problem were mountings and a lot of reinforcing went into bracing and strengthening those running boards to take the weight. We tried aircraft style landing lights in those nacelles and while very good even with elaborate rubber mounting they couldn't cop the vibration and we reverted to marine light. Cheers.
