Mower And Equipment Modifications
#1

You fellas can tell me if this is where you want to talk about mower mods.

 

I've been modding all my mowers over the years.

In the late 90's it was Rover 20" "self drives" which were pretty much 1940's technology and full of reliability problems.

Then in the early 00's, I spent a day modding each industry donkey HRU216 Hondas before they even mowed the first lawn. They were gutless, had handle issues, blade issues, filter issues and wouldn't catch grass if it was wet. But they were solid and reliable, so were worth doing all the modifications on to turn them into a proper mower.

 

My current mowers are the new HRX217 Hondas (which I was importing from the USA years ago, and pushing Honda Australia to do the same).

They don't need as much modding - a snorkle (from a honda powered victa), independant blade clutch and drive levers, auto choke fix, a steel re-enforcement for the mulch ramp, and lower the blades 7mm so they can actually cut the grass without hanging up on the deck. It would be nice to have a better height adjustment system, but if you get your head around the American 4x adjuster system, you can actually control a lot more about how the mower cuts and how the lawn finishes. It just needs to be finer than 8 settings - of which you only use 1 or 2 because everything else is too high for Aussie lawns.

"Can't" is a dirty 4 letter word.
If someone says "Can't" , take the "T" off the end and brew in boiling water.
Sip on your 'T, relax, and take a look at what you've got left to work with.

The clutch throw on a HRU can be shortened with an added stop screw. this makes it possible to use the clutch one handed with your hand still holding the handles - ideal for fast turns. "The wasted time on a lawn is in the turns"

Also a throttle / gear guard is a huge benefit to stop branches snagging the levers. Honda won't do this mod because new plastic throttle levers retail over $20 each and only cost cents to make.

To get wet grass into the catcher, part of the problem is a clogged chute. To fix this a few mods to the rear axle and chute area make a huge improvement in flow.

The original under tray mod. Note handles are what supports the mower, not the chassis brackets, and the retaining catch is manual not automatic.

One of the crucial things to do to a HRX is to lower the blades. This picture shows the blades off with the alloy disc spacer beside them. By lowering the blades 7mm the cutting height on 2nd setting is more suitable to the equivalent "5th notch" on a HRU, and no longer "hangs up" the deck edges on thicker turf.

One of the really annoying things on the new blade brake mowers is having to hold the blade brake on constantly. It restricts movement and speed. When the engine isn't revving full blast and the grass is a bit deep, re-engaging the clutch will stall the engine.

Here is a first attempt at a latching blade brake lever.

However , I wanted a better, short throw drive clutch and the blade brake was in the way. 

By robbing the drive clutch lever off an old HRU and moving the blade brake to the upper half RH handle area it worked out brilliantly. The self drive can be operated independantly of the blade brake, and with a less cumbersome short throw drive clutch the speed and manouverability has returned.

Here is a picture with 2x mower handles left is before and right is after the mods.

Some great info there Arfa ;).

I am pretty much like you if a new Honda comes home it gets modified before it ever cuts a lawn.

Yeah - Iand beat me to it ! The hose is like 2 inch dia. Way overkill. but it's also a bit short. You'll have to drill some holes to mount the handle filter, the rest goes on with some cable ties.

Lots of mods I'm seeing

Back in the old days you'd buy a mower with all the mods done by the shop and this mower would run rings around anything today stock or modified.

giving out one of these machines to you the tester you would want one that's how good they were as they out performed todays machines.

Alas they are gone but if the manufacturer was to bring it back you contractors would have a serious look at it.

Just fitted the snorkel, Arfa was right, it,s a bit short, should have been at least the filter length longer but it does fit a few machines.

Victa part no AF07881A
Honda part no L1245-P06-100
Upper Filter AF07883A

Didnt think to check with Honda dealer re filter price but as Iand said plenty on E Bay.

Very impressive, wondering if you have an engineering or welding / fabrication background, or if you're just naturally inclined with this type of work? Either way, some great inspiration there for a lot of contractors  ;)

 

Thanks Steve. 

Just a rural background, (so used to doing the impossible, with nothing, yesterday)

Everyone has the ability - but not many get cornered into the "have to"

Sorry Drew - I only just saw your question tonight..

If you read the 3rd post you'll see a photo of the blades and stuff. there is a silver disc on the top right of the photo. I spun this up on the lathe from a bit of aluminium. It's 7mm thick where the blades bolt through. You will also need some longer High tensile bolts to replace the shorter originals.

If you make a spacer it must be balanced to avoid dangerous vibration.

Just mucking around with this today (rained out)

Took 2x old upper blades and cut the ends off so there was just the centre part. 

A little bit of a grind on the high points so they stack together properly, and they make a 5.5mm spacer.

New high tensile longer bolts needed and it should save me spinning up another spacer.

When I fit it to the next mower I'll post up some pictures.

Excellent thanks.

 

That was my first thought, just add another blade but didnt pursue it.

Basically the higher you get it the cleaner air your motor ( Mower car truck ) takes in.

I always had a snorkel on my Toyota,s for deep water wading and i mean deep, more than one occasion bonnet under water.

 

I dont plan on water wading with any of my mowers though.

Without the snorkel the airfilter on my 197's needed cleaning nearly every day and replaced quite often(can remember how often just remember that i couldn't believe what a difference the snorkel made and have never run one without since)with the snorkel the top one is blown or just tapped clean everyday or so  and replaced every month or 2 or longer in winter  and the bottom one is also only changed every couple of months one of the things i dislike about my TPE and 196 is how the airfilter clogs up and i can't just buy a snorkel for them.
