I got stuck into the Rover this morning, excited to see what I could get sorted. There were a few small details I wanted to address, and in the process, I found a few other issues that I suspect led the previous owner to replace it.
The first thing I wanted to get sorted was the sloppy front axle, if I couldn’t fix this, the chassis would be effectively junk. After a quick look yesterday, the threaded hook anchors were loose and simply needed to be tightened up.
I could have simply nipped them up, however I decided to drop the axle and inspect the plastic bushes. I’ve seen worse than these, but seeing as I had some in stock, I decided to replace them. I also had a set of new old stock anchor hardware, but I managed to get the old ones tight, solving the problem.
In this image taken before removal, you can see the gap between the axle/bush and the top of the deck recess.
This is the same system used on the later ProCut models, so I have previous experience here. Those bushes and anchor hardware are long obsolete and extremely hard to find. The funny thing is, its because of these that I began doing my own repairs.
After a test start first thing, I could hear a light ticking noise that came and went. This was initially concerning, but then I remembered the state of the blades. With the deck in the air, I could see where the blades had been contacting the side of the aluminium deck. And while the blade hardware was TIGHT, they were far too sloppy. As luck would have it, I had a new set of blades, the 18-inch and 20-inch Rover’s used the same parts. This is when I discovered that the crush washers had been installed incorrectly, which was causing the blades to be sloppy. With the new blades fitted, a quick test start confirmed the fix.
Hearing that noise, and the sloppy front axle, this is where I suspect the previous owner bailed on the mower, thinking it was worn out. No, it just needed some attention and maintenance. Oh, and the blades put on the correct way!
After the test start, I left it running to warm up the oil for an oil change. The oil that eventually drained out was fairly contaminated. I ended up putting mineral SAE30 in it, purely because it's an old girl now with plenty of miles on it. Considering the oil that came out of it, and how quickly the usually bright red SAE30 turned brown, I’m going to use this oil as a flush and change it again in the near future.
Next, I needed to dive into the air filter situation. As per the previous post, the owner decided not to run the snorkel filter, instead relying on the filters at the engine. With the covers removed, um, yep……………………..
I’ll give those filters credit though, they did their jobs considering how clean the inner box was, any flecks of dirt were from me opening it up.
From here, I decided to just pull the filter box from the carburettor and clean things properly. I then soaked all of the filter covers with Surfex, including the snorkel tube and cap. Some agitation with a brush, I rinsed with the hose and set them aside to dry. Because I found something else that needed attention………………………….
That hose takes fuel from the tank to the carburettor, which believe it or not, wasn’t leaking. This hose has a very thick wall, which would is probably why it wasn't leaking, but no doubt it wouldn't be long before it did. So, the question was, replace it or leave it alone? My hesitation here stems from the plastic barb leading out of the fuel tank can often be brittle, so I didn’t want to junk a very expensive part of the engine. In the end, I thought I’d only have to pull it all apart again, and considering I had the hose in stock, I though I may as well do it now. The old hose came off easily, the new hose went back very firmly, assisted by a little Stihl press fluid, the old clamps reused. Fresh fuel in the tank verified my work.
Strangely, the fuel I drained out of the tank was bright blue, almost as if it was 2-stroke. Now, the engine wasn’t smoking on this fuel, but my fuel is always amber yellow. So, I’m not sure what’s up there.
At this point, I noticed the cylinder baffle plate was not installed correctly. This was an easy fix, the front bolts holding the blower shroud were removed, allowing enough upward movement for me to slot the baffle back to where it should have been. After reinstalling the bolts, I then went around and tightened up the valve cover bolts, which are known to back out over time and cause leaks.
Next, I dove into the parts department for a new spark plug, the old one was well past its use by date. These Intek’s take the same RC12YC Champion plugs that Briggs uses in all of its OHV mower engine these days, from the base 300e right up to the big boy 850-series. While I had the engine running to warm up the oil, I noticed the occasional slight miss, well the new plug fixed that.
At this point, I swung from small engine mechanic to detailer because I JUST HAD to remove the 26 years’ worth of oil and dirt from this engine. To avoid getting water where it shouldn’t be, I reinstalled the filter base to the carb, then the cover without filters installed. The snorkel outlet was then plugged with a towel. Shine Supply Wise Guy and Surfex teamed up here for degreasing, I then blasted the bulk of the grime off with the pressure washer. A reapplication of Wise Guy, then some agitation with a brush got the rest clean. The deck, wheels, catcher and snorkel housing got the same treatment.
It was then time for an application of Carpro Hydr02, then lashings of Megs Hyper Dressing.
After drying off with the blower, it was time for another trip to the spare parts department for some new filters. All three I had in stock! I really don’t know why you wouldn’t use a filter in the snorkel, in fact it was rather silly of Rover to put that sticker on the housing. If the previous owner had, the old filters would not have looked like they did.
Finally, I polished the muffler and used some steel wool to remove the surface rust from the chrome handle bars. On that front, I went around and tightened all of the handle mounting hardware, which were just a touch sloppy. This combined with the repaired axle made the mower feel much tighter, almost like new!
And with that, I’m very happy with the results here. Yes, a few battle scars, and it has the standard issue paint drips over the deck (explain to me how this happens, why wouldn’t you move the mower when painting your garage?). But for a 26-year old mower, you can’t really ask for more…………………..
Now, I never do this for financial gain, its purely my own curiosity and enjoyment. But I thought it would be insightful to see what this project has cost me (so far). It also relates to a theory I will explain shortly. Obviously, I haven’t included a labour charge here.
Now, lets address the elephant in the room. The previous owner basically gave this high-end lawn mower away. Yes, it needed some maintenance thrown at it, but a drop in the ocean all things considered. Because what did he replace it with? An EGO battery powered mower worth the better part of $1000.
Now, I actually respect the EGO brand, I have several EGO tools powered by THE BEST battery technology out there. And that joins several other battery-powered garden tools. But, will he get 26-years out of that mower? Not even close! Plastic deck vs aluminium alloy? Batteries don’t last forever, whereas an iron bore Briggs will. The original purchase price of that Rover would have been about $800 in 1999, plus 26 years of fuel and oil. But it’s not even close to the same amount he will eventually spend replenishing batteries over “life” of that EGO. And guess what? This Rover has another 26 years left in it.
So, which is the more economical and environmentally sound choice here? I’d wager spending that $90 on maintenance would have been the better choice. And that’s before you consider the limitations of an EGO mower.
