| I’m getting a d21 in a little over a week It’s a series 1 with a series 2 motor and turbo the muffler is outside the Hood and like 5 foot tall. Question is aren’t all d21s turbo or not have muffler under the hood. It won’t fit in my barn with this tall muffler. Is there a muffler with the turbo or is it straight pipe and if it still needs a muffler is the factory one under the hood. If I can put muffler under the hood or put just a short pipe on it I can keep it inside. So much for having extra room in my barn. Is the d21 all solid gears and clutch like a b or c where there is no hydrolic clutch and you could pull start it just curious not going too. Hasn’t ran in 8 years is there anything to really check on these besides normal fluid and filter changes and clean fuel system. Why do some have chrome grill and some painted. This is bare back tractor with just hitch and hydrolics. D21s have any bad things like rear ends or axles. Thanks guys will post pic and more stuff when I pick it up - Ryan |

Tractors with turbos should not have mufflers. Just a straight pipe. A muffler will put a damper on the turbo's performance by restricting air flow. Series Is without the turbo had a horizontal muffler under the hood with a 4' pipe coming up through the hood. There is no hydraulic clutch. Just a 4 speed tranny with a 2 speed box - Foot clutch must be used at all times. Regarding the chrome grille, I think it was the earlier models that had it. They went to the painted grilles sometime after 66. Mine is an early 66 and it is chrome. The rear ends are not as strong as a 220, but if you are not doing any real heavy plowing you shouldn't have any problems. Be sure to post pictures when you get it home! ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

It should be illegal to run a 426 with any type of muffler. ------------- A little CQB never hurt anybody. |
