A heater for the John Deere Gator 825i / 825m / 855D, 2011–2022
This Ice Crusher heater kit is built specifically for the John Deere Gator 825i / 825m / 855D — not a universal heater adapted to fit. It puts 14,600 BTU of engine-coolant heat through 5 adjustable vents, including dedicated windshield defrost. The heater unit mounts behind glove box passenger side. Because it runs on engine coolant, it makes real heat without draining your battery; the fan draws about what a factory blower does.

Installation
The heater mounts behind the glove box on the passenger side. You tap into the engine coolant and route the hose to the heater; the instructions show every step with pictures. Basic hand tools do the job.
Options
Seat rows: Pick one or two rows of seats so we pack the right length of coolant hose. The price doesn’t change.

Gator 825i

Gator 825i S4
MaxStat (+$85.99): Adds about 10–15° of cab heat by keeping the engine thermostat from cutting coolant flow to the heater core.

Hose clamp tools (+$24.99): A pair of clamp-off pliers that seal hoses up to 2 inches, so the coolant tie-in stays clean. Handy on radiator hoses too.

Questions we hear
What does the MaxStat add?
About 10–15° more cab heat. It is an inline bypass thermostat that keeps hot coolant flowing to the heater core when the engine thermostat would otherwise close, so the heat stays steady instead of cycling. Add it at checkout; this machine uses the 1-inch (26 mm) size. It comes with a 180°F thermostat, or 192°F if you ask before it ships.
Will it drain my battery?
No. The heat comes from your engine’s coolant, not the battery. The fan draws about what a factory blower does.
Does it fit the Gator XUV 835 or 865?
No. Those machines use a different kit: the XUV 835 / 865 heater.
How long does the install take?
Plan on 4–8 hours depending on experience. Experienced do-it-yourselfers land at the low end; first-timers should set aside a full day and follow the picture-rich instructions step by step.
Do I need the hose clamp tools?
You can install without them, but they make the coolant tie-in faster and cleaner. They pinch the hoses shut so coolant doesn’t pour out, and less air gets into the system, which makes bleeding the air out much easier. Sold as a pair; they fit hoses up to 2 inches.
