I own both a GC2610 and a 2016 GC1720. Yes, during winter cold the fuel Gels up including Winter Diesel if you live where it goes below zero like me.
In winter I add Diesel Gel fighting additive to my tank, with full tank I should say. I also will use Diesel 911 before starting it up in an hour or two. I no longer waste my time believing the Gas Stations crappy fuel is winterized. So including what I had just stated I "proactively" remove the fuel filter after a below zero night and before starting. I wipe it with paper towels, use a wooden toothpick to clean the ribs of the Gel in the filter (even with additives it happens). I fill the plastic fuel filter cover with the same filter placed inside 50% filled with Diesel 911 and 50% from the Diesel when reopening the petcock. WELCOME TO DIESEL ****.....Lol Joking" Diesel Gel will happen starting at 17 degrees Fahrenheit & below...... (Remember, ANY storage containers even 55 gallon drums of Diesel exposed to those cold temperatures need to having Anti-Gel additives mixed in or it will happen when you refuel with crappy stored Diesel.)
Above post is assuming your familiar with your fuel filter location. If not, use cardboard lay it down to keep dry. WITH ENGINE OFF, lay under Drivers side and look for a small about 5 ounce size almost clear plastic cap that has a grey metal ring at the top that is "Hand" tightened. Before touching it, on the side of the fuel unit you are looking at there is a metal petcock. Down position is for fuel and up sideways is fuel line shut off. Moves easily in one direction only...do not force it to go where it does not want to go! Unscrew the metal ring and wiggle off the plastic cover. It has an "O" Ring on it so do not damage it. If Gel has taken over the Filter may stay on and not slide off with the cover. Either way you will see the Diesel Fuel Gel we're all talking about. look up into the openings where the top of the filter was touching. If Gel is clogging two holes up there use whatever "CLEAN" utensil or toll you have to clean them out. Now take the fuel filter and cover with you inside Garage or if you can stand the smell of Diesel in the House. Use the wooden toothpick lightly to clean the Gel out from the Ribs of the filter, wipe out the inside of the cover. I do not recommend any ignition sources used near fuels. But yes, I have head from people using from a distance a Hair Dryer on Low to melt the Gel on the filter but I found there is no need to do so. Yes, Diesel is much safer than Gas but it is not a good practice to do or even a safe one at that.....Now go out with fuel filter back in cover "Hole Up", ensure metal ring is slipped back over it, get back under. Take the time to slide the cover "Slowly aligned with the filter hole" until the "O" Ring seats. Then screw on Metal Ring "Hand Tightened" turn petcock back down to fuel position. (Remember, I already own some Diesel 911 so I add it 50% in the cover before I seat the "O" Ring. Now it is time to start, Turn Key where you hear the fuel injector noise and yellow Glow Plugs noise wait 15 seconds. Turn that bad boy on, idle at low RPM until engine is warm before cranking it higher. (Some people do not know better and they tear up there Diesel Engines). If engine requires a higher throttle for start up, immediately take the RPM's down once the engine starts....I have a 2630 Snow Thrower on mine during the Winter cause I have a LONG gravel driveway out here in the country....BTW, Any Fuel issue that is not mechanical pump etc... is not covered by a new Tractor warranty and Dealers are expensive!!!!
