I got tired of eating twice-blown snow, so I got the local Massey dealer to install a cab on the GC2310 and hydraulic chute rotator on the Puma. Found a heater on eBay, it's either the Maradyne 5000 or a clone. The day the tractor was ready, the heater came in the mail.
I spent a cold Sunday morning plumbing the heater up. I plumbed in to the water pump/thermostat bypass loop. On the little Iseki engine a 3/8 hose fit loosely, but 5/16 fit perfect. Some brass barb fittings and a couple of brass 1/2" threaded couplers, and I had it adapted up to the 5/8 pipes on the heater.
It was a hurry-up job just to get it working before the storm, and is not in it's final form. I'm going to add a diverter valve and tee so I can shut off the flow to the heater in the Summer, and I have to wire up a SPDT toggle for the two speed fan.
It doesn't throw massive heat, but it certainly keeps the cab warm. I think the 5/16 hose might be too small for massive heat, although, grabbing the brass fittings to check the temp shows it's plenty hot.
My opinion is that the bypass is the best spot to plumb in to for a cab heater. Any and all heat the engine puts into the coolant goes through that bypass until such time as the thermostat opens, and the flow through there stays hot after that. Plumbing into the radiator hoses can delay heat until the thermostat opens, not my idea of fun.
