    Robin Engine Nikki Carb mystery

    The PT422 starting surging, and application of some choke made it go away. This pointed to a carb cleaning. I took the carb off of the engine. To my surprise, there was a small hose connected to the bottom side. (See attached pix, I tried to circle the points of interest) It's connected to...

    Potential Robin Engine Cold Start Remedy

    Have a potential remedy I thought of last night on the Robin Engine cold start difficulties: Just a note, I have not tried this. So proceed at your own discretion. Here is my cold start set-up along with synthetic 5W-30 oil in the engine, dino 10W-40 in the hydraulic tank. I use two magnetic...

    Tube or Slime

    I purchased some used wheel/tires for my garden tractor to put on in the winter. There is some cracking on the sidewalls causing some air loss. Would you guys try to slime this, or install tubes. I'm concerned that if I put in slime, I could not put in tubes at a latter date. I'm also...

    Snowblower Conversion

    Thought you guys would like to see a snowblower that I converted for use with the PT422. I took a 42” single stage snowblower and made new wings with a drift cutter to get 48” width. Used the same hydraulic motor as the PT lawn mowers since it was the right speed. (Tip speed of the auger is...

    Hydraulic Filter Poll

    Just wanted to check to see what people are using for a hydraulic filter on the PT4XX series power tracs. I'm still using the PT hydraulic filter, but with a $50 min order, wanted to see what others are using. Post the filter make and number. thanks Duane

    Engine Horsepower: Rule of Thumb

    People like rules of thumb to help evaluate things on an apple to apple basis. A common question is the comparison of diesel versus gas engines in a tractor. The common seat of the pants perception is that a diesel engine provides more useful power in tractor work than a gas engine. I think...

    Tires  Tire Slime

    After putting tire slime in a tire, can you still let air out the valve stem? Does the slime clog up the valve stem so it's difficult to add/remove air. Thanks, I picked up a nail, and was wondering whether to plug or slime it. Duane

    Hydraulic Reservoir Cap

    It looks like the new PTs come with a filtered hydraulic cap on the reservoir. Good idea. My PT along with the one year and older PTs have just a vented cap. Our caps are not threaded, just a two tang half turn type. I have not seen any two tang type filtered caps, just threaded ones. Has...

    PT Stump Grinder

    Does anyone know the hydraulic motor displacement (cubic inches per revolution) or grinder blade RPM for the stump grinder for the 400 series? Looks like PT offers a stump grinder with non-sharpening, non-relaceable teeth, and then a blade with replaceable teeth. The blade alone with...

    New PT425 Engine Compartment-Long

    Taking a stab at how the engine compartment layout change affects the overall engine compartment heat just for fun. The following numbers are ballparks for a PT425. Typically, a gallon of gas contains about 115,000 Btu per gallon. At a rate of consumption of 2.2 gallons per hour (full load)...

    Power Trac Draft Control

    Just curious to see how many of you guys that are operating the 1430 and bigger units, are using draft control. It seems like it would be a nice feature. It would seem especially useful when plowing etc in float when the tractor arms ride over the implement. How does Power Trac accomplish...

    Power Trac Lubricant for Spherical Ends

    Did'nt know if everyone saw this post. Super Lube is recommended by PT on the spherical rod joints etc. Super Lube may be hard to find, but at least you can get the same stuff at Lowes or a John Deere dealer. Post: In case the the url does'nt make it, look under 'lubricants' under 'what...

    PT Hydraulic Oil Temperature

    One of the design changes I have been contemplating for a while is the installation of a shroud within the PT hood. A while back I calculated the heat removal capacity of the hydraulic radiator on the PT. It has more than ample capacity (in addition to the heat rejection from the metal...

    Oil & Fuel  Deutz Diesel RPM

    Hey Charlie or Sedgewood, I was showing the brochures of the PTs to a person at work today and they asked "what is the max RPM of the diesel engine"?. Do you guys know. thanks Duane

    Yanmar Thermostart

    A good friend of mine recently purchased a Yanmar 1720D. (did not receive an operating manual with it.). He was having a lot of difficulty starting the tractor at temps below 40F. I did a search of cold start threads under Yanmar and discovered the thread regarding the thermostart system. I...
