I started my machine this morning it’s about 30 outside lows in 20s last nite I haven’t run it in 3 weeks . I let it warm up until water was around 150 just brought from idle to about 1/4 throttle just to move to barn and machine moved just fine let it sit and warm up some more then went to move it backed it up and turned it around at about 1/4 throttle started forward moved pretty normal speed then throttled it up and it slowed down at full throttle I’m mean it seemed like I moved the stick half way for speed ? It dint matter forward or revers slowed throttle back to 1/4 and moved it and the speed was back just not at full throttle ? Checked oil it’s fine only have 40 hrs since serviced all filters and changed all fluids using all cat fluids . Any ideas?
