operation of levers on 900 series

I have 3 levers I need a refresher on. Which way does the draft control work? Up to plow or down. On the left side there are two levers one works the PTO but what does the other do? Which way and for what. Thanks.
 
The right side under the seat area is the lever for draft control and on the opposite or left side under the seat are two more levers. The smaller one operates the PTO and right next to that is a larger lever and I can't remember what it is for. Thanks for your response.

Exactly what model is your tractor?

Below photos show left side of SOS and gear drive versions taken from the owners manual.

I hope the photos come out. I don't know much about this computer stuff. I didn't want to make this a big story. But The clutch isn't working. with it running I can't get it to shift into anything. I pulled it into my shop thinking there maybe some ice inside as it was parked outside. It seems that it has a two speed transmission on the 4 speed. I just can't remember and without it working I can't just try it out. I think this tractor is a put together from several and as close as I can come is like a 941. Any ideas?? I hope when it thaws out it will be working. [/img]
 
Kirk-NJ got you going on the draft lever. The way I always used to use to remember which way it works is down for 'in' the ground such as plowing and up for 'on' the ground such as a blade or mower.
 
It is a howard reduction transmission That's what that plate is sandwiched between the end of the trans and the front of the rear housing. It may be possible that it was knocked out off gear by someone moving the lever. In neutral detent the tractor will not move. Try moving the lever

I was thinking that maybe Ice was causing my problem but I have her in the shop and I have a clutch problem. It will not allow me to shift anything. It will grind if I try to shift the any of the levers so I figure the clutch is stuck to the fly wheel. What is the best book I can buy to repair this tractor? By looking at her picture what tractor do you think I have? Some years ago I tried to figure it out and some how I figured I had a 941 but I don't know. The stamping says it's a 621 but I know that's just the transmission so it has been put together from different tractors. Any ideas on how to break the clutch loose?
 
Pull the starter, with the clutch pedal blocked down, spray some
BP Blaster with a bent straw spray behind flywheel, rotate
flywheel with big screwdriver and spray. Give it a couple on
days. You can also jack up rear and rock rear wheels.

If you have decoded the model number correctly, you have a mutt. The paint scheme suggests a 1957-1962 01 Series Powermaster that most likely came with a 5-speed and was later converted to 4-speed.

If you can provide date codes from the engine or differential, we can narrow down the year it was likely manufactured.

The part number cast into the lower right side of the engine block will help ID the engine size.
 
Tin and brake system is the X01 series so basically you have a
901 series and call it a model 941 (even though I don't think
they made a 941)
Check you engine numbers. Could be a 134 engine which would make
the model number a 741.

I tried to find some information on the Howard gear reduction box but can't find anything that looks like mine. Do you know where I can find a picture and some information on this box I have? This has the 172 engine and a four speed transmission. Thanks for your help.
 
The howard you have is rare and I don't think you will find much info on them. They were suppose to be better then the earlier howards. I have howard tractors and have sold some howards over the
years. I have only come across two in all the years I have been doing this. One was an NAA and one was a 641. I suspect the 641 was an early one before the change in the spindles for the rear
coupler. Jim Webb had taken some photos of his when he took it out of an NAA. Hit the link for photos. This will give you some idea what's behind the plate. They were supposed to be very strong
units. I've heard people call them Bulletproof.
Here are a couple of photos on the earlier howard out of an N tractor for comparison.

here is what I did. I jacked one wheel up and tried to rock it back and forth and tried to rock it for a while. Took the starter motor off and poured about a gal of diesel in the bell housing put the starter motor back on and used it to rotate the flywheel and tire. many times. it is totally soaked it in diesel and left it for a day. The engine runs like normal. So today I wanted to try and pull it and the wheels will not turn the engine over. Just drags in the mud with Ice under it. The top two inches has thawed out over a hot spell. To my surprise one wheel would turn and the other would slide and turn the other direction. one side then the other and it would not turn the engine over. So I took the spark plugs out still would not turn the engine while dragging it. Any ideas???
 
Thanks for sending me the link for Smiths old tractor for a 4 speed transmission stuck in two gears. I have tried everything to free up the transmission . I can't get the flywheel to turn back. I can get it to move a little but it just comes back to where I started after moving about two teeth unless I have the clutch in. (at least I know the pressure plate is releasing but it won't do any good with the clutch in will it? Is there something else I can do?

Remove the spark plugs while counter rotating the flywheel to make it easier to turn.

You may have to enlist a second person to serve as a ratchet pawl. One pry bar through the starter hole to turn it and another through the timing hole to hold your purchase.

You want to turn the engine backwards at least 1 revolution.

Clutch must be engaged when jacking the flywheel so it can turn the transmission input shaft.

Have you pulled the shifter cover to verify which gears are locked? If so, you may try separating gears that way.

If neither of above solutions work, I'm afraid you're looking at disassembly. Not all but most locked gear problems can be resolved without a tractor split.
 
Well I got it loose with one hell of a snap. Sounded like I hit it with big hammer. I was thinking what I needed was some help to turn the fly wheel and I had tried every thing I knew of. Then I thought why not use compressed air in the piston going in reverse. found a cylinder that had just about ready to fire. I put 120 psi to move it back and it made it so mush easier to move the fly wheel. Put in the clutch and moved to another cylinder getting ready to fire and drove that one in reverse and moved the fly wheel and it snapped big and loud. Do they always make a load snap? transmission now unlocked and easy to turn the fly wheel. This process should help others. I didn't have time to but it back together but everything seems to turn. Thanks for every ones help in figuring this out. If I need to post again I'll start a new one as I'm getting lost in this one. Didn't want to start a long story but it turned out that way. Thank for sticking with me. One happy man today.
 
Glad you got it freed up - Check each gear set to ensure the loud bang wasn't teeth breaking.

Don't recall if you've pulled the shifter to check for worn parts that caused the tranny to lock up in the first place.
 
it's broken. Now I have to break her apart. How much damage will happen if I try to move her on a trailer under power or is it best to now try it? What gear is broken on?

I would use a come along to load your tractor instead of risking more transmission damage.

Your photo is too tight for positive ID. But if I had to guess, it would be first gear that's chipped. Look at parts diagram below and post back with part number of chipped gears.

In all likelihood you will see chipped teeth on the counter shaft once you get the main shaft out of the way.
