muffler question on the Carlton 7015

AAASTUMPSERVICE · Feb 27, 2012

I came across this video on you tube... Carlton 7015 Tracked Stump Grinder - YouTube
it looks like this model came with a muffler, is that a requirement in another state or country? I couldnt really tell how much quieter the machine was on the video than my machne but i would think their would be some difference? I thought about putting a different exhaust on mine only because it hits me n the face everytime i rev it up to grind, maybe if i got it to point out the other direction or had a muffler setup like in the video it would be quieter and keep me out of the diesel smoke...curious if it would have any power los with a muffler like this?

Muffler Question

I've been selling grinders for years and I believe Carlton received many complaints about the noise of the engine. Previous mufflers vibrated off of the engine over time. Deutz won't be offered for awhile as they can't seem to meet the Tier 4 regulations and the Kubota's that manufacturers are converting to have mufflers. I don't believe it's a requirement however, it could be in the UK as they must meet the CE requirements. Most diesels need a muffler as they need back pressure. If you're getting smoke in your face, get a different exhaust riser or move the current riser in a different position. Make sure you have a raincap on the riser as you don't want water going into the turbo and ruining it.

Hope this helps!

The muffler system on the later year 7015s with the Deutz is quite flimsy as Carlton will acknowledge. Carlton is proud of the new Kubota muffler. The Deutz muffler system uses rubber bushings that wear out quickly, a flex pipe that breaks, engine mount bolts that shear off in the engine, and support plates that need welding. Still, it is considerably quieter than the non-muffled 60 hp Deutz turbo such as on my 4400-4. Pep Boys to the rescue - they have $5.00 18" long flex pipes, $2.00 exhaust adapters in various diameters, and lots of clamps. Between Pep Boys and my welder we keep the muffler system in one piece. btw I put an $18.00 Pep Boys glass pack onto the exhaust pipe of my non-muffled 60 hp 4400-4 and it actually cuts down the noise a bit.

Do you have any pictures of your setup? Does adding onto the stock exhaust hurt engine performance?

The first two pics show the 7015 muffler setup. In pic #1 you see the Pep Boys flex pipe cause the original flex pipe flanges and exhaust pipe cracked from vibration and stress. In pic #2 you see the muffler support plate with numerous welds, one of two engine mount bolts (just below the pump hoses) missing sheared off in the engine. There are 4 funky looking elongated double rubber bushing studs for the 4 corners where the muffler mounts to the top plate and in between the 2 plates that Carlton sells for $50 a set but they wear out in 50 hours so I don't bother. Pic #3 shows the Pep Boys glass pack on my 4400-4 60hp turbo. I cut off part of the original exhaust before mounting the glass pack. No drop in performance, in fact my Deutz dealer recommended it for some noise reduction (Note that my exhaust pipe bent somewhat years ago but no drop in performance from the constricted air flow).

btw I never post here but allow me to say that Jeff, Huey, Johnny, Marshall, Dean and the Parts Dept. at Carlton are a great small corp. family of regular guys who specialize in stumpers, love their work, and really care about their customers and equipment nationwide.

I agree 100%. These guys really care about the products they build, the customers who purchase those products.
