Generally this is a sure indicator that you have gotten air into your brake lines. The way this most often happens is if you are leaking some fluid somewhere and then the reservoir on the master cylinder got too low and you pumped the air into the lines. Another way it can happen is if you have a leak and the air gets sucked into the line via that. USUALLY if this happens, it's just before a complete brake failure though. The first thing is to check the level in your master cylinder. If that is good, the next thing is to bleed the brakes at each wheel. After that if you have no air bubbles coming out of the brakes at any of the wheels and you have a good supply of fluid then chances are your master cylinder or an power assist has gone bad.

Pull glow plugs, then try. If had small water leak. Got water on top pision.

There is usually a diagram on left side of the deck, that show the direction the belt should go, note start the belt over the engine pulley and work your way from there, the spindle pulleys take the v-groove part of the belt and the idler pulleys take the flat/wider part of the belt

Go to any auto parts store and have the battery tested for free, after verifying a good battery, check, & clean all connections with sand paper. Battery, cables, ground wire to body... After verifying connections, test "stator" charging system for engine... It will be located behind the flywheel.

With the machine off, check to see if anything is jammed underneath the deck, or around belts, clean everything off. try to manual turn the blades with you hand (tractor off and key out of the ignition) if blades don't remove, take off deck belt and then try and move each blade individually, see it any bearings are seized. Check to see if any one of your safety switches were disconnected, and test out the pto switch for power.

Yes... Most clutches can be adjusted... You'll need a feeler gauge and a socket set, and the manual. I believe it's a .012" feeler gauge and a 12mm socket... All 3 nuts have to be turned a quarter turn each at a time until optimal gap is obtained. There are 3 slots to place the feeler gauge in between the clutch disc. Note it may take 1-5 quarter turns on each one...

Clean battery connections, and re tighten battery cables... Check ground connection to body...

Could be a few things, but sounds like your low on hydraulic fluid... check to see that you have enough hydraulic fluid in the system... Top up with fluid, if not full! Could also be an air pocket in one of the lines... So try and bleed out system...

Drain fuel completely from tank, fuel line, and carburetor... Change fuel filter, change spark plug(s) add FRESH gas... Not 1 week, month or year old gas... (Can't be contaminated, or mixed with old fuel) there will be a drain screw on the carburetor (at the side of the bowl) You may need some quick start to get the engine to initially start up and keep it running with the spray until the fuel system fills up with fresh fuel and stays started.

Fill the tank and all fuel filters with diesel... There should be one or two fuel pressure release valves on the fuel line, one after the pump and filter. If there's only one, losen it, and crank over engine, let all the air out of the system, and wait till there's only diesel, gushing out of the line, before you tighten up the valve. If there's 2... Open both and Start with the one farthest away from the injectors...when fuel comes close the farthest one first, then the other one.

It could be corroded... water, dirt, etc, could have finally taken a toll on it.... Try spraying some electrical friendly lube on the shaft on the switch and try open and close it without the machine running... If not. You'll have to replace the switch.

Expose the shifter mechanism from the base, look to see it the is an obstruction that is causing the shifter not to shift... Pay attention to the shifter mechanism ends and see if it's worn out, they sell both OEM and aftermarket shifter arms and linkages..
