have you ever wondered what the difference is between a timberwolf and a force chipper
well today is your chance because we're going to put them side by side we're Machinery nation
and we bring you videos about tools and Machinery every Tuesday and Friday so please click subscribe
let's crack on tested by Machinery Nation so a couple months ago I checked out the brand
new Force st6 PhD yes it's the petrol six inch chipper and I was so impressed with it
I had to find out what the competition was like so I asked a few tree guys that said
look I want to compare some chippers what should I do and they said I had to put it
up against a Timber wall and have an equal test so today we've got the six inch diesel
version from Forced and the six inch diesel version from Timberwolf today we are going
to put them up side by side to see what the differences are if any we are going to chip
some brush we're going to chip some bigger Timber we're even gonna put a couple fencing
sticks through it to make it as Fair as possible and also look at how easy they are to service
and maintain but full disclosure this is a used timberwolf and that is a nearly new forced
but we have serviced them both and they both have brand new blazing to make this as Fair
as possible let's crack on so General spec wise they are very very similar they are both
six inch chippers and they've got exactly the same four-cylinder Kubota Engine in both
of them I don't think you can get fairer than that so we've got two chippers and we've got
two piles of brush which weigh in at exactly 200 kilos how do I know that because I weighed
it all individually yesterday yes it took me hours but it had to be fair so 200 kilos
for the timberwolf and 200 kilos with the forced let's send it through the Timberwolf
to start with right so how we're going to time the test is for when I start chipping
I'm going to throw it in the chipper as quickly as possible and we're going to time it from
when the chip starts coming out the end of the spout to when it finishes I think that's
the way we can do it I think it's the best way right send it through
thank you

there it is
it went through the chip has gone through the Timberwolf I gotta say it's a lot quicker
to chip it than it was to weigh it what machine right thank you to Oregon for uh lovely PPE
always love it got the boots on got the helm on and the gloves love it time for some forced
action there's a major difference between the fourth and the Timberwolf is this dial
here so you can actually turn the speed of the rollers up and down so if you want a really
fine chip you can turn it down if you want a really chunky chip you can do it out so
I asked the question to some people who've got three of these four strippers and said
where do you have it in general use and they said about there so I'm going with that about
there
[Music]

[Music]
next test something a little bit more chunky so I've got some five inch pieces of Cypress
here and to be honest that's probably what you're putting through your chippers most
of the time they both weigh 13 and a half kilos I was like chopping off little bits
of it each time Timberwolf first let's go [Music]
chunky chunky it's got the big stick in the forest
s
right now times the fencing stake test yes we have two four inch by five foot six post
straight out of our farm supplies as you can see no tampering still got the tantalized
on the top we're going to put them both in exactly the same time one into each chipper
and I'm going to have them literally tickling at the rollers so they're ready to go and
go three two one boom straight in right let's firing both up and put them in
foreign
[Music]
[Music] I think that's a photo finish and what a wasted two fencing Stakes I think my
goats would have preferred them there we go how much wood can a chipper chip and how far
can it Chuck let's find out no this is not a microphone it is a decibel meter because
we are going to put here on the end of the hopper and see what the decibel meter reading
is because we all know chippers are noisy machines so let's check it out
because it's all very well for a chipper being able to Chip and be able to cope with the
material that you want to be able to put through it but maintenance is as a big a thing some
of these chippers do a lot of hours major hours used day after day after day so maintenance
is important and it's going to be done easily and efficiently so let's check out the Timberwolf
to start with how easy it is to maintain and then we'll have a look at the Forest right
so engine access on the Timberwolf you've got two plastic panels each side which you
do need a spanner 19 mil here nice ratchets balance that will make it easier you've got
to undo this bolt on the side to slide this panel out so main general maintenance on the
engine you'd have to do this on each one
does have a flat Bonnet so you know you have actually got some of the big tools and then
that slides out and reveals your beautiful Kubota four-cylinder diesel engine so there
is everything and then on the other side it's exactly the same under the bolt slide off
the cover everything's all there nice and easy to get to right same again put it back
on
bolt back in again
like 90 newton meters of torque that is obviously right it's a daily task checking oil coolant
levels nice and easy it's got a little hatch at the top that's probably where you get the
rattle from but it's got a key on it you're supposed to put a key in there to unlock it
I don't have the key luckily a bit of a cheat just do that and you can open it up so you
can get it to your dipstick not me the one in there and your coolant and everything so
you can check that on a daily without having to slide the side panels off it's quite handy
there we go back together again why we're in this area of the machine I'm going to mention
this bit right this bit here adjusts the spout to where you want to put it great nice and
easy to access but if you Bang Your Head on it it hurts and I speak from experience don't
like don't like it looks like a testicle don't like it so you want to change the blades on
your Timberwolf this is how you do it again you need some tools as you would on anything
there we are not your mil spanner again there seems to be a running theme here in 19 mil
undo this plate here oh no locks Two Nuts yes I can count I do like the flat top for
putting your tools on probably don't do the paintwork any good yeah obviously a nice technician
we put a nice little Rodney little mat there wouldn't they so once you've got them out
you can then grab this handle and pull out right highly recommend cut proof gloves because
obviously chipper blades are sharp you know that spin the flywheel around until you find
a blade which are four inch Long Blade double-sided and there they are look okay there's your
blade you've rested down there so once you've got your blade there on that level section
you'll see a bolt hole there and a bolt hole in there as well you've got a hole in through
here so you can put a locking bar in there so you slide a bar in through there which
then goes into the flywheel into that hole which then allows your flywheel to lock in
place you have a 20 mil socket on the back in here to unlock the lock nuts then the square
shanked round flat headed bolts will pop out but do you got to get the back bolt out you've
got to take the top plate off up here to be able to release this spring because this spring
is in the way of that bolt coming out once you've got that out of the way you can then
pop those bolts out turn your blade over and pop it back in again will change the blade
and then pop a lock nut in back a new lock nuts on the back talk to spec put it all back
together but most people know that you've got to keep your blade shut but what a lot
of people forget is the Anvil so you've got your blade coming down but it's going against
the Anvil you think of a pair of scissors it's got to have two sides for it to cut exactly
the same with the chipper and it's called The Anvil to get the Anvil out it's a little
bit more complicated and probably something for a dealer to do unless you're extremely
you know good at maintenance mechanics what I'm going to call it so let's just give you
a brief show so I need to take this card off anyway which you'd have to do to take our
spring off for the blades so I'll take this one off first once you've got the bolts out
take the cover off like so eat that out of the way where it gets complicated because
that whole feed roller has got to come out to access the Anvil bolts so first of all
take your Springs off each side two Springs each side pop them off you've got these two
bars at the top pop them off and then you've got the hydraulic motor this side to be able
to take off and then you can slide that top feed roller out then you need some big Allen
keys because you've got to get down in there because is three hex headed sunken bolts that
you'll need to take out on top of the Anvil I was taking those three out you only need
to put a slide hammer into the side of the Anvil and then have a slide hammer and pull
the Anvil out and then you can change it turn it over whatever you can do to it and put
it back in again and then put everything back together probably more of a technician's job
in your dealership or Workshop job or if you're very technically minded and great but a little
bit more involved to be able to get to the Anvil on this one and then you've got to put
it all back together again right so the forced engine maintenance how would you get to the
engine nice and easy solid steel cover over the whole thing so nothing plastic on a force
whatsoever bar the mud guards to be quite honest I quite like seeing metal mud guards
now that 750 kilo towing capacity isn't a problem whole of the construction is metal
on a forced and you've got these little Clips on the side unclip one of them here unclip
one on the other side and the whole bonnet lifts up so you can get everything nice and
easy checking your oil servicing checking your coolant everything's in there and then
for full maintenance you can obviously take the gas dry off and fold it right back over
so you can get to everything that's in there nice and easy you straightening onto your
belts right here everything's really accessible and you can get into the top of the engine
there isn't too many obstructions great feature really really nice simple also that Bonnet
is very aerodynamic you know your wind behind your vehicle going up through everything's
flowing in the right direction I like that it's a nice feature blade access on a forced
pop your Bonnet out access cover here two bolts two 19 mil volts which you just undo
them fairly easily yes there we go nice wearer spanners put the back in your pocket all right
look at that nice flat area up here put your tools again if you need to do your bolts there
we are pop around the other side don't put your bolts there you'll see why then grab
your chute pull that over here there it is it's open it's not just taking you two bolts
out pulled up your cover you can access your flywheel really easily you can pull the flywheel
around to access your blade which is right there in front of you very easy to get to
and on the fourth chipper compared to the Timberwolf is it's two eight inch blades on
here rather than two four inch blades whereas on the Timberwolf we've got two four inch
step blades so you're sort of getting one cup per bit every other Revolution whereas
with this one you're getting two full wide cuts every time that Blade's hitting the timber
all you got to do on here again there's Square Shanks bolts Two Nuts under your nuts pop
them off pull your shank bolts out take your blades out turn your blades around sharpen
new blades whatever you're doing and then pop them back in again do them back up close
your cover two bolts in Easy right so I'm going to stress again how important it is
to keep up with your Anvil and change it and turn it in everything you need to do and there's
no different on the forced but this is such a great design fantastic design to take the
Anvil off on a forced you've got a 90 mil bolt which you'll need a socket for rather
than the spanner take the bowler take the Locking plate out have your slide hammer screw
your slide hammer on and pull out your Anvil done turn your envelope put it back in or
replace it put the Locking plate back on and put your bolt in simple as that done so controls
starting engine revs all of that jazz Timberwolf nice and simple turn the key you've got a
glow plug light and then you can start her up and you've got an hour clock to the right
of it simple nice and easy and then below here you've also got your greasing point so
you've just got one single place to put your grease gun and grease everything and then
your throttle is up on your Hopper they're nice and easy to get to nice access yeah just
simple easy robust how everyone knows how to use it there's a little bit more going
on with the force because you've got this digital display here so when you turn the
key on it goes through a sort of warming up process so it goes as these dots going along
and once the dots get to the end that means you can start your machine it's nice because
it tells you it's going through its processes what it's doing is just checking that the
whole system is okay because on this display it will bring you up reading so there's a
problem with the machine it will give you a code pointing you towards where the problem
Elements which for backup purposes is great because you can say hello Mr technician on
the other end of the phone I've got code s345292 what's the problem and he goes mate it's not
hitched up you know or whatever and I think that's great system to have some people don't
like going down the computerized route but it's got it illness the way everything is
going you're seeing this sort of thing more and more on Machinery again greasing points
all the way down through here nice need to get to there's five on this one where there's
only four on the Timberwolf so I'm not going to follow them around see where they're going
once you've got your speed control dial here for your feed rollers so you can control them
up and down the smaller chip bigger chip faster chip and slower chipping it's nice to have
that I think it's a great feature and bear in mind on the fencing State tests we've done
just now we had this turned down so the feed rollers were going exactly the same speed
as it was on the Timberwolf because we thought that was only fair whereas you could have
turned it right up and those feed rollers could have been gone really fast but they
won't throttle on the right hand side there download up high it's all there feed roller
controls oh yeah estimate and go forwards and obviously reverse if you need to and they
are on here on the thimble you've got these buttons here which seems like solid and quite
robust tell us in the comments if you have any comments on either of these machines on
how you think they work what I don't like is this little baggy wiring this sort of wiring
sticking out I feel if you're going down a track or something you know most of the time
where these chippers are going are you know it can be places where there's going to be
lots of overgrown stuff and everything I feel they could just gets [ __ ] I don't know
is that is that a thing let me know in the comments was that massive fan of the force
buttons they're smooth they're round they don't have anything protruding from them and
you just touch them and when I first saw them I thought oh that looks a bit of a gimmick
but apparently right these are from the London Underground so if you go to the London ground
or your laminar then you probably recognize them anyway because that's what you used to
stop and start the trains or open the doors or whatever something like that and nice and
easy no wires no cabling just looks like it's just great like it so the biggest question
are you team Timberwolf or are you team fours we've had a look at the machines put some
Timber through them and to be quite honest very similar results when it comes to actually
doing what they're designed for doing but when it comes to the maintenance side of things
the force that is just so so easy to maintain and the easier things are to maintain the
more likely people are to maintain them and trust me I speak from experience the Timberwolf
great chipper design robust it's all there the forced has got some great features on
it so much of a muchness but let us know in the comments whether you're team Timberwolf
or team forced we're Machinery nation and we bring you videos every Tuesday and Friday
