blade. The left hand joystick used to
select travel direction and to provide
infinite speed control up to a
maximum of 9.7 km/h. Side mounted
buttons allow manual selection of any
of the 10 speed increments to suit
particular operating requirements. To
hold the 1650L stationary when the
engine is switched off, the machine
comes as standard with a heavy-duty,
spring-applied hydraulic release
parking brake.
Low-effort blade
hydraulics
The right hand joystick controls all the
motions of the PAT (power, angle and tilt)
blade by means of logical forward/reverse,
left/right and twisting movements.
The low-effort hydraulics aid precise blade
adjustment on the move to maximise load
retention and carry out efficient dozing to the
required grades. A separate right hand lever
operates the optional ripper (not fitted on the
Monthyon demonstration machine) that can
be equipped with three or five teeth.

The use of a narrow instrumentation panel and a tapered bonnet view provides a clear view of the front of the
tracks and both sides of the 3.98m wide, 3.2m³ capacity PAT blade.
The test dozer had the 2.13m gauge LGP (low ground pressure) tracks with 864mm wide shoes which maximise
flotation when used on soft ground. Other track options are the 1.87m gauge XLT (extra long track) with 610mm track
shoes for precision grading and the 2.13m gauge WT (wide track) with 864mm shoes – most suitable when extra
stability and a wider blade are needed for finish grading or slope work.
Sealed and lubricated track pins
Ground pressure varies from the XLT at 42.8kPa, to the WT at 38.7kPa and the LGP undercarriage, which puts down
just 31.9kPa. All models use the Case Lubricated Track system with its sealed and lubricated pins. An optional Case
Extended Life Track, with a second hardened bushing, is available for abrasive soil conditions.
All the three LGP, XLT and WT configurations utilise Case Lubricated Track with sealed and lubricated pins as
standard. An option for sustained use on abrasive ground is the more durable Case Extended Life Track (CELT).
Daily service checks can be carried out from ground level and there are quick-disconnect diagnostic test points to
assist any necessary troubleshooting. Mechanics will appreciate the side tilting operator platform and cab. It takes less
than ten minutes to ‘open up’ the machine in this way to obtain really good access to its power train, electrical and
hydraulic systems.
The 1650L and 1150K were launched in the USA at the ConExpo exhibition in 2008. Now their availability in
Europe will provide Case and its dealers with more sales opportunities. Time will tell whether the other Case
bulldozers are also offered in Europe. [CP&E]
