756 won't move or steer in very cold weather

My 756 lost it's prime on the mcv valve, so I cannot steer and the tractor won't move. I am able to raise and lower the loader, operate the fast hitch and the pto turns. The low side of the ta is out. This only happens when it is very cold.... 5 degrees or less. I am assuming I have ice built up and making my filter into a snow cone! I plan on changing the filter Saturday morning when I have the time. The hytran is a couple years old and still looks very good. I would rather not drain and refill it. I don't use the tractor very often, so, I believe condensation is causing the problem.

I have been searching for solutions on the internet to stop this issue from happening. Some possible solutions include:
1. adding the allied filter extension to use 2 filters...allowing more oil to pass thru. I have the 17 gpm pump installed.
2. replacing a drain plug with a drain plug heater that you plug in. Not sure which one to get or which plug to replace.
3. slapping on 1 or 2 magnetic oil pan heaters...1 by the filter and 1 by the mcv?

I have a torpedo type heater that I can point at the tractor to warm it up enough after I change the filter and hope it picks up prime. If not, I have in the past taken the 5/8 nut off the back of the mcv and started it to prime it. Very messy...hoping not to need this step again.

Sorry for the long post. Hoping to be able to push the snow off of the lane without the hassle of defrosting the system.

Thanks a lot for all of your advice. I wimped out on changing the filter as it was about 5 degrees when I started this morning and the tractor is in a open front, dirt floor barn. I pointed the heater towards the filter area as I poured in about 5 gallons of molasses consistency hytran....all I had on hand. I suddenly became very religious....praying that it would work! I fired it up and voila it primed as it should and I was able to go and steer. I worked it by pushing snow in my lane and opened up my drifted over road...so, I can get out.

I will order and install the double filter from allied....when it gets a bit warmer and I can move the tractor to the garage with a cement floor. I definitely can't afford a cozy heated shop....so, this will have to make do....

Sometimes simple works. Do the filter thing as well. Jim

Yep Delta Nailed it the 17 gal pump is sucking more then the 9 gal and the 9 gal is getting on the weak side . Plus you have some water in your Hyd. system and the ice cristles are blocking the filter a bit . You probably don't run the tractor hard enough often enough to cook out moisture . and the seal on the pick up tube is probably sucking air also . Now there are two ways to solve the air sucking , one is tear the tractor down and replace all the seals on the suction side , always replace the gskt on the hyd filter and make sure that the filter housing is FLAT at the bolt holes , Or just dump in five extra gallons once you are at the fulll mark . Next find one of them Allied filter extension housings and add a second Hyd filter . Then and only then can you flow enough oil thru the filter . Or you can BUILT A Cozzy warm tractor shed and keep your toy inside where you keep it 70 degrees . Then all your problem will go away .

A 'regular' filter has too much restriction for a 17 gpm pump,especially in cold weather. It is starveing the mcv pump. More pronounced when the mcv is worn.Far a test,you can remove the filter and see how it performs.A double/increased flow filter system may be nessesary.As was said adding 5 gal of fluid may help.

Over filling it by 5 gallons might help prime it (after changing the filter). Jim

On his sounds more like he needs to change his oil more often along with reg filter changes . If you do not run them hard often to cook out the moisture you can not believe how much water will collect in the large frames in short order . With me i stopped running hy Tran ( yep go ahead and beat me ) , the reason why is Hy Tran will suspend water and the filter is suppose to filter it out . well that is all well and GOOD BUT the filter will plug fast and ok so you change the filter if there is a lot of water in the fluid the filter will plug again in short order FAST . I have seen around here on systems that had milk shake or coffee with cream colored oil that just dumping out twenty gallon in the drain pan and putting a new filter in and running it in less then and hour the oil is milky again and maybe after a dozen or so filters it will Start to clean up . Buy not running hy trans and not usen the tractor that much one can get under it and crack ALL the drain plugs and let her drip dry BEFORE starting . BUT IF someone just bounces in the seat and starts the tractor all that condensation gets sucked into the filter and it plugs off fast and the bypass screen opens and then the rest gets mixed in to the oil and now you have coffee with cream once again . I go thru this every year with my friend and i get to here him whine about the cost of changing the oil when all it would take is for him to just crack the drain plugs and let them dip till ya see oil coming out before start up.
