The web is abuzz with questions about the new 420 cc Craftsman motor!  Ok, the buzz isn’t quite as strong as the latest iPhone 5 rumors, Dancing With The Stars or even Anne Hathaway but for those of you looking for an inexpensive lawn tractor or riding mower the questions you have are more than relevant.

I’ll keep this article short. Feel free to ask questions in the comments.

Here is what I know:

The engine was introduced last year in the Craftsman Model 25000 riding lawn mower and the owners really like the power it has. They also brag about the fuel economy.

It is designed from the ground up to handle today’s unleaded and 10% ethanol blended fuels.

It has a full pressure lube oil system with oil filter. This means it will run on inclines without running out of oil.  It is better than all the other motors currently on the $1400 and less lawn tractors.

It is not made by Briggs & Stratton or Kawasaki. It is made by MTD. MTD has been making engines for quite some time now and they are proving to be reliable and trustworthy engines.

It is designed to replace competitor’s engines up to 500 cc.

I HAVE THIS ENGINE IN MY MOWER. DOES ANYONE KNOW OF A REUSABLE AIR FILTER AND IF SO MAYBE A PART NUMBER OR MANUFACTURER OF THE FILTER. THE EXPERTS AT K & N DIDN’T KNOW.

The gas cap being cracked or off did not work

Paul , my neighbor has the Sears rer1000 and after about 20-30minutes of mowing it sounds like it is running out of gas and dies. If you let it sit for about an hour it will start up and do the same thing. Any ideas in what could be the culprit? He’s had it to a local mechanic and at first he said it was the low oil sensor , then it might be vapor locked, and now he’s putting a head gasket in it , but I don’t think it has anything to do with any of these items.… Read more »

Did the gas cap idea work for you

Have you had any feedback on the hydro trans now being offered? I’ve seen it on Cub Cadet & Troy Built 30″ rear engine models. I test drove the Cub Cadet & liked it. I want to know if I can pull a yard cart or lawn roller with it. The Cub I drove didn’t have the hitch plate installed, but I saw it in the user manual. My 36″ lawn roller is full of pea gravel (doesn’t freeze) and is pretty heavy. I’ve never had a hydro, and don’t want to toast a new piece of equipment. I can’t… Read more »

Purchased the Craftsman 29000 series rear engine. What a sweetheart! Right up til it will not start…just start with the safety switches. Seat, deck, engagement and brake / clutch combo switch. After testing all of them…none bad! Simply stated, the brake switch had simply slipped out of position. It looked as though it was attached properly, it was not. On the Lawn again, Can’t wait to get on the lawn again fa la la la la. Great bang for the $$$.

Paul I have a rear engine Sears LT 1500 that needs the carburetor rebuilt. How does the carburetor come off or how do you remove the item 139 studs to get the carburetor off the engine block?

I successfully threaded a Briggs & Stratton Oil Drain Valve 5401K onto the engine. That has a specification of 3/8″ x 18 NPTF. The valve was unsuccessful because the brilliant design of the Craftsman 247.288820 meant that the steering pushrod went through that same space and broke off the valve. I am on my 3rd or 4th season and this time my 1/4 extension rounded out the hole so I need to use a screw extractor on it and perhaps replace it with a more standard automotive plug. This thing has never wanted to come out. Maintenance parts seem hard… Read more »

Hi Paul. I am really intersted in this LT1500 as it sure is Budget Friendly at Sears, at $999 out the door, versus the John Deere Models. I understand there is a difference with this LT1500 model to the ohn Deere 100 Series D125, not apple to apples, but if I am mowing on flat ground, less than 1/4 acre in total, with the features of the 420 motor, pressure lube, and 7 speed trans in the LT-1500, and the D-125 being $1799, plus the bonus of a free portable Weber Grill, the Deere is almost double this model, and… Read more »

I just purchased the sear rear engine model 290000. This is a great running maching and easy to use. I used it late last year and need to change the oil and filter. The original parts seem to be over priced and i am wonder what after market replacements i can use for the following. I used the lawn mover late last year and it is a great running machine and very user friendly.
Oil Filter
Spark Plug
Air Cleaner
Gas Filter

I have 29000 and have changed the oil several times using the plastic sleeve to try to direct the flow of oil away form the mower…..it doesn’t work!
Can I find out the thread size on the drain plug and just screw in an extension tube?
Regards, Bill

I’ve been trying to find the stock oil drain plug # 710-05311 thread size, or specifications for 5 weeks! I’ve called searsparts, mtd, search the Internet, and it must be some Chinese space secret! Know one seems to know, but hope I can get this simple info before I die,or this rider goes to the scrap yard. Maybe someone at MIT or NASA has this info! LOL

I have a LT1500 420 cc lawn tractor.

I’ve run into a problem changing the oil.
The drain plug has about a ¼ inch square female hole in it.
I tried a ¼ inch socket extension in the hole and the end of the extension sheared off when I tried to turn the plug.
I imagine I need to buy a square socket to remove the plug, but I don’t know the correct size.
As I said it’s about ¼ inch square, but it may be a mm size.
It sure doesn’t give the size in the manual

The plug is in there pretty tight.

Use the end of a 3/8″ socket drive extension, it’s square and it fits!
