Ford 6610 Block Heater
Rather than heating the whole engine block, this sort of burner only heats the oil pan. It aids in improving viscosity and minimizing frictional damage by reducing the thickness of the oil on the motor. To be safe, plug in your engine compartment heater when the temperature drops to -15° C or lower.
If you ride a diesel car, you may need to use the automotive engine burner to maintain the temperature from falling too low. Most block heater cables can be located wrapped in a vividly colored piece of tape around the right or left ends of your tractor’s engine area.
Ford 6610 PTO Problems
The PTO system on the 6610 is self-contained, indicating it works separately from the drivetrain and clutch. It engages the PTO with a manually applied, spring-released gear pack. The lever you use to activate it turns a loop in the PTO relief valve to turn the clutch bag’s oil on and off.
Your tractor’s PTO is necessary for completing specific tasks. You’re not totally out of good fortune if your PTO isn’t riveting; there are several measures you can do to improve matters. Several reasons behind PTO issues are mentioned below.
- Low transmission oil levels or low air pressure levels
- faulty electrical wiring
- It’s possible that anything is interfering with the circuit.
Solution to Ford 6610 PTO Problems

The PTO Clutch Isn’t Getting Disengage
If your PTO clutch isn’t working and you’re not sure why then one possibility is it doesn’t have enough voltage to operate. Locate the clutch gear assembly and consult your instruction booklet to see where your machine’s battery is. Use a voltmeter to check power once that’s been found. Your voltmeter should read at least 12.5 volts; anything less will require charging.
The PTO grinds away but refuses to engage
There’s really hardly anything you can do to change it from the outside in this scenario. This is an issue that usually necessitates the replacement of your clutch pack. When the PTO is overloaded, the clutch pack is damaged.
This can potentially cause damage to the PTO clutching bands and driveshaft, necessitating their replacement. If you believe this is the issue, you should consult a mechanic who is familiar with your tractor.
Ford 6610 PTO Shaft Removal
Making Use of a Hammer
If the PTO shaft appears to be firmly attached to the tractor, then you can stress the problem by removing the PTO shaft with a hammer. You can use a hammer to strike the PTO shaft, but ensure to place a wood block below it. You don’t have to slam the PTO as hard as you think. Sometimes all it takes is a slight shove for it to loosen up.
Keeping the Connection Lubricated
If corrosion is the source of the PTO shaft jamming, the lubrication approach can be used. Rust will appear, particularly if the PTO units are exposed to water and are not used. It would help if you lubed the PTO shaft with plenty of lubricating oil to prevent it from becoming stuck on the tractor because of rust. You may break it out of connection this way.
Disengage the PTO Shaft with the Pry Bar
Destroying the PTO shaft component is another way to disconnect the PTO shaft from the tractor. To gain sufficient elbow room, you must first dig out the pits. Then take down the PTO shield. This isn’t difficult to accomplish. After that, you can go out and get a pry bar. Begin prying as you go about. The problem is that any resistant locking mechanism must be dismantled.
Ford 6610: Reviews and Ratings

Despite its age, Ford’s 6610 tractor always appears to handle whatever is thrown at it without issue. It offers a lot of interesting characteristics that make it a worthy investment. The 6610 has proven to be very convenient and robust over the decades, having been used with a wood splitter in the cold, spraying when needed, harvesting with a baler, and strolling around the field with a trailer delivering feed to the cattle out on the hills.
Overall, it was a neat and efficient package, but early versions had porous automotive components, which led to oil spillage; this was a severe problem that necessitated design adjustments and the development of a heavy-duty, ribbed engine block. It is, above all, the right kind of tractor provided for fellow citizens like you!
