The colloquial term "Ferguson 28" is sometimes used in Australia and New Zealand for later models of the TE-20 including the petrol TEA-20 and diesel TEF-20.[citation needed] "Ferguson 28" has never been an official tractor model designation. Initially the TE20 had the 'Continental' Z120 23HP engine, as did the Detroit-built TO20 introduced a year later. The 80 mm bore 'Standard' petrol engine was phased in in mid-1947 as the TEA-20, approximately 3,000 of the 20,500 tractors built to 31 December 1947 being TEA-20s. Subsequent to the introduction of the 85 mm bore TED-20 in April 1949, the petrol engine was also made with an 85 mm bore, which increased its power to just over 28 hp. The term "Fergie 28" refers to the nominal horsepower of the later range of tractors. To benefit from the reputation of the later models in the used tractor market, the 23HP TE-20 is often advertised simply as TE-20; only very rarely is it referred to in Australia as a "Ferguson 23". In North America the 'Standard' petrol-engined TEA-20s with the 85 mm bore were known and advertised as TE-2085s.

- Check the owner’s manual for the correct fluid type and amount.

- **Check for Leaks**:
- Start the tractor and let it run for a few minutes.
- Inspect for leaks around the pan and filter.

- **Additional Repairs (If Necessary)**
- If the transmission fluid is contaminated or if you notice grinding or slipping, parts like the clutch plates or bands may need replacement.
- Inspect seals and gaskets; replace if they show signs of wear or leaks.

- **Final Steps**
- Recheck fluid levels after running the tractor.
- Dispose of old fluid and filters properly at a recycling center.

To exhaust the pipe on a Massey Ferguson TE-20 tractor, you need to understand the exhaust system's role and the theory behind the process. Here’s a structured explanation:

### Theory
The exhaust system in a tractor, including the Massey Ferguson TE-20, is designed to channel engine combustion gases away from the engine and reduce harmful emissions. The exhaust pipe connects the engine's exhaust manifold to the atmosphere, allowing gases to exit efficiently. Over time, exhaust pipes can become corroded, blocked, or damaged, leading to reduced engine performance, increased back pressure, or even engine damage.

When you "exhaust pipe" a tractor, you are likely referring to either cleaning, repairing, or replacing the exhaust pipe. Here’s how you would typically approach this:

### Steps to Repair or Replace the Exhaust Pipe

1. **Identify the Issue**:
- Inspect the exhaust pipe for signs of rust, holes, or blockages. A damaged exhaust pipe can lead to back pressure, affecting engine performance.

2. **Gather Tools and Materials**:
- You will need wrenches, a socket set, a new exhaust pipe (if replacing), and possibly exhaust tape or sealant.

3. **Prepare the Tractor**:
- Ensure the tractor is parked on a flat surface, and turn off the engine. Allow it to cool down to avoid burns.

4. **Remove the Old Exhaust Pipe**:
- Locate the bolts or clamps securing the exhaust pipe to the exhaust manifold and the muffler. Remove these fasteners carefully.
- Detach the old exhaust pipe from the manifold and muffler. If it's corroded, you may need to use penetrating oil to loosen the connections.

5. **Inspect the Exhaust Manifold and Muffler**:
- Check the manifold and muffler for damage or rust. Clean any debris or soot buildup to ensure a proper seal with the new pipe.

6. **Install the New Exhaust Pipe**:
- Position the new exhaust pipe in place, aligning it with the exhaust manifold and muffler.
- Secure it using the original or new bolts/clamps. Ensure all connections are tight to prevent leaks.

7. **Test for Leaks**:
- Start the tractor and let it idle. Listen for any unusual noises or leaks. You can use a soapy water solution to detect leaks at the joints.

8. **Final Check**:
- After a short run, recheck the connections and tighten if necessary. Ensure there is no smoke or fumes escaping from any joints.

### Conclusion
By replacing or repairing the exhaust pipe, you restore the system's ability to efficiently expel combustion gases, thereby reducing back pressure and improving engine performance. A properly functioning exhaust system is crucial for maintaining the health of the tractor's engine and ensuring compliance with emission standards.
