I personnally have never seen a trailer with shocks on them. 30-40Kg
is fine for a trailer weighing in at 300-400kg (i.e. the average
household tailer). tongue weight gets real important when you start
talking about short trailers with 4000kg on them (a small skid steer
loader for example). the local rental place LOVES to load them right
up on the tongue of their trailer.... probably 40-50% trailer weight
on the tongue... the trailer tows like crap... when I load the trailer
with the loader more on the wheels it tows soooooooo much better.

The local garage here builds their own design of trailer, made of 6mm thick
box section and I girder steel, with leaf springs off 1 ton or 2 ton light
trucks and shocks.

And they go up from there. 4000Kg skid steer? they built the car trailer
they haul a 6500Kg tractor with FEL and tray themselves.

Our small household trailer was re-done by them with Bedford van springs
when we shifted out to the farm, and rather than towning light loads of
branches to the city dump we started hauling heavy loads of gravel. they
reinforced it majorly but we still often borrow the neighbours shocked
trailer if we're gonna be hauling real loads of gravel or suchlike.

I don't know if you have them in NZ, but the Bobcat is the most often
used brand name. (kind of like Kleenex for facial tissue). check out
www.bobcat.com the ones I usually use are older models that weigh in
at about 2000kg (743B) and 3000kg (853H). my point was how much
tongue weight will affect the handling of a trailer, esp with short
trailers (under 4 m OAL) the longer the trailer the more forgiving
they are.

I know of bobcats, The Q-mark was actually to express surprise at the
weight, most of th ones round here tend to be about 3 tonners (853H maybe?
don't know the number sorry). Dingos are becoming far more popular now for
household hire and landscaping, they're only about 800 to 900 Kg. they're
small stand-on-top skid steers.

the 9 series actually can get quite large the 980 weighs in at over
14,000lbs! I've never actually seen one, most around here use 743's
or 863's. I can imagine trying to use a stand up loader... a bobcat
beats you up bad enough..

Heres some info on the Toro dingos, I can't find the Australian origionals
used here in NZ. If you look closely at some of the pictures the operators
do look a bit higher on some and theres a little red shelf jutting out,
others are walkbehind models.
