I have a model 606 Huskee/MTD lawn tractor that pops out of

Resolved Question:

I have a model 606 Huskee/MTD lawn tractor that pops out of gear in the forward position. I adjusted the Detent shaft assembly and it helped for a few weeks but now is getting worse. Do I need a new drive shaft? Reference pages 40 and 41 in owners manual "Automatic Lawn Tractor Model Series 606"

This is NOT something that can really be diagnised for sure without me actually being there and doing tome testing by driving it and so forth.

Ranwell1 :

But most likely what you are going to find out is that the ENTIRE transmission is going to have to be replaced.


Ranwell1 :

These usually are not something that we recommend that they be rebuilt.


Ranwell1 :

They usually do not work very well if they are taken apart and the cost of rebuilding them usually are not too far from the cost of replacing them..


Ranwell1 :

But of you want to try to check this out, I am including a complete parts breakdown of the transmission for you.


Ranwell1 :

The part number for the complete transmission is 753-05851

Ranwell1 :

The actual problem is most likely in the two gears #15 in the diagram
The clutch collar #16 in the diagram
The Detent shaft #20 in the diagram
And probably the detent ball and spring #21 & #22
There is also a good chance thet the shaft #17 may also be worn.

But the gears and the clutch collar are almost always bad along with the detent shaft.

Thanks for the info on the transmission. It's what the Lawn guy said but I wanted a different opinion. If you owned this Huskee tractor, with your skill level, would you fix the transmission or replace it. I have some skill as a mechanic but it may not be worth the time and money if its a better value all around to replace it with a new one. Is it better to buy direct from MTD or go on line? Looks like Huskee and Sears is the same tractor, am I correct? I'm heading out the door to go to work but will check back for your answer later. Thanks, Bill

Actually if you really want my opinion, I wouldn't even bother fixing the tractor at all, I would buy a new tractor.....

But if you are asking if I would fix the transmission or replace the transmission, I would Replace the transmission.


Usually the factory doesn't sell to customers, but you might check with them.

Online usually will give you a better price. Check They usually have a decent prices.
