What are the head bolt torque specifications for a briggs and stratton 31C707 engine?
Torque Head Bolts
Since I do not have a way to send you a picture, I will describe the
sequence. With the cylinder head in a position where there are two holes on
your left and an open, blank, space on your right in the vertical surfaces
(you might want to make a sketch of this) - I will give the sequence going
in a clockwise direction. The open blank space I refer to is in the pushrod
No. 1 is in the center of the side closest to you. Number the holes 1 thru 7 going clockwise.
Tightening sequence - 1, 3, 6, 8, 5, 2, 4, 7.
Torque to 220 inch lbs. Tighten first round to 75 inch lbs next step to 150
inch lbs next to 200 inch lbs, then final step to 220 inch lbs. and recheck.
Tighten all bolts in sequence to whatever figure you are using.

Why will blades will not disengage?
check your return spring on the deck. it goes from hole in bracket welded to deck to hole in moving lever that one of the deck pulleys is attached to. if spring is missing or broke, it will not dissengage or may dissengage slowly. If spring is there, the moving lever may have debris under it or may be bent. If spring is there, remove deck and try pushing the pully with the spring to see if it breaks free.

I have loss of power on my tractor when blade and transmission are engaged. Engine sputters and backfires.
We're assuming that nothing has been done to diagnose your problem. I personally would start by removing the carburetor bowl and check for any contamination of either water or any other form of contaminants. If anything is found clean the carburetor bowl all out. The carburetor bowl I'm referring to sits on the very bottom of the carburetor and normally is held on with a brass colored plug or it will have a fuel shut off solenoid which will have a single wire that can be disconnected. Both styles( plug or solenoid) can be removed with a 1/2 wrench. If it is the electric solenoid style you may have to sacrifice one of your wrenches by grinding it down for there's not much room between the solenoid and the carburetor bowl. Care will have to be taken when reinstalling the bowl for the seal can fall away from where it should sit and can be pinched causing a leak. Start there and if that's not your problem we'll check other common options.

Troy bilt mower pony
are your blades engaged when you try to do this??
if so it is a back up safety feature from factory,turn blades off and try?
Or put the ignition switch in the position that will keep the mower running when you go in reverse with the blades on or push a button on dash when you go in reverse,probably not on yours just some of the features on some models and just something to look for on yours

Steering gear slips
You have the steering shaft the pinion gear on the end of the shaft and the stationary gear at the bottom on the frame. Either the gears are worn out or the steering shaft has too much play in it causing the gears to slip.

How do you change the transmission belt
There is a instruction decal,on how the belt is installed,around the pulleys. This decal can be found under the left foot rest,on most Craftsman tractors. Didn't find on left footrest,try right footrest. Hope this help answering your question. Sincerely,Brad Locke 11/23/15

WHAT LUBE GOES IN TRANSAXEL
I believe that's a tecumseh trans axle. They really aren't a serviceable part. But it you're brave... Yeah I've torn them apart to replace bearings and such. I never found a "spec" for the lube but it's really heavy. I used a nice sticky molly grease when ever I put one back together.
