I have found that running the rotary mower less than the required 540-rpm PTO speed and traveling too fast across the ground for the conditions results in more windrowing of the cut material. A slower ground speed with the mower running at 540 PTO speed gives the mower blades more time to...

DPF and DEF are used for two different results in altering diesel engine exhaust emissions. DPF is an exhaust filter that removes and collects soot. The regeneration cycle is necessary to burn off the collected soot. Regeneration is accomplished in two ways, active and passive. Active...

It could be that the original hose deteriorates prematurely from heat or other environmental sources and could eventually allow unfiltered air to enter the engine. I'll ask the tech when he comes to my place to replace the hose this week and post his answer. Bill

Today, I received a call from my Kubota dealer about a mandatory update on my L5460HSTC that I purchased last June. He is sending a tech out to my place next week to make the change which, if I understand correctly, is a short hose on the turbocharger intake. Bill

I purchased a new Kubota L3830GST in 2006 and put over 1,300 hours on it. I always thought I wanted a gear drive tractor for mowing and drawbar work . Last spring, I traded it for a new L5460HSTC and what a difference! I wasn't a fan of HST until I purchased this tractor. I mow pasture with...

Pieces of red hot carbon are ejected by non-DPF engines also and that's why spark arrestors are required on exhaust systems in some locations/conditions. Bill

The DPF is under the hood, insulated, and far away from anything combustible on the ground. The tractor exhaust system goes though a long tailpipe and at the end there is a 10-inch long air diffuser that mixes cool outside air with the exhaust gas thus cooling it. The exhaust stream blows out...

On my L5460HSTC, the "Auto Regen" is the default setting and it automatically comes on each time the engine is started. No button pushing is necessary. If I wanted temporarily delay the active regeneration, I would have to push buttons. My tractor has gone through two active regeneration...

Clutch in a HST? Where is the clutch pedal? Bill

All I've done with the tractor since it was delivered at the end of June is mow. For 540 on the PTO, I run the engine at 2.400 RPM. I have used my grapple a couple of times to load and haul cut brush to one of my burn piles. When using the grapple I slow the engine down to about 1,800-2,000...

In addition to no smoke and diesel smell lingering in my shop after starting, the direct injection common rail four cylinder turbocharged diesel engine in my L5460HSTC is quieter running than my old L3830GST with three cylinder naturally aspirated indirect injection diesel engine. With direct...

Yep, that's what I thought too in 2006 when I purchased my new L3830GST. I traded that tractor in mainly for the air conditioned cab in June of this year for a L5460HSTC and after about 10 hours with the hydrostatic transmission, I wouldn't go back to a gear drive. I'm retired from a tractor...

Our Kubota Tier 4 tractors have both passive and active regeneration. When the engine speed is high enough and the load on the engine is adequate to produce enough exhaust heat, it will burn off the soot in the DPF and the reason you will see lowering of the soot levels without seeing the...

I agree.:) Bill

Have you measured the width of your tractor? I'm wondering if a 5' rotary mower will cut out the tracks of the tractor. I currently own a L3830GST (a replacement L5460 HSTC is on order) with R4 tires and a 6' rotary mower barely cuts out the tracks. Personally, I don't suspect a problem with...
